Apply fall preemergence herbicide to avoid spring weeds

As soil temperatures cool, now is the time to plan for preemergence herbicide applications to eradicate common cool-season weeds like annual bluegrass and lawn burweed, said a Texas A&M AgriLife Extension Service expert.

Chrissie Segars, Ph.D., AgriLife Extension turfgrass specialist, Dallas, said homeowners looking to improve the look and feel of their lawns by preventing annual weeds and burs should prepare to apply fall preemergence herbicides. Preemergence herbicides are designed to disrupt the germination and emergence of unfavorable plants.

Other fall and winter management practices like proper irrigation will also ensure turfgrass emerges healthy in the spring.

“Fall weed management is an important part of annual turfgrass maintenance,” she said. “It rids lawns of undesirable plants that compete with our turfgrass and helps your lawn get a good start in the spring.”

Ridding lawns of weeds

Preemergence herbicide treatments in the fall can help rid your lawn of grassy weeds like annual bluegrass and rescuegrass, and broadleaf weeds like henbit, chickweed, Carolina geranium and lawn burweed. Choosing the right herbicide can seem daunting, but AgriLife Extension has a number of publications dedicated to identifying weeds and herbicide selection.

Segars said preemergence active ingredients are an important consideration for tackling unwanted weeds. Products will typically list a range of plants it will control whether perennial or annual and broadleaf plants or grasses. Preemergence herbicides are most effective on annual weeds, while other weeds must be controlled with post-emergence applications.

“Having knowledge of seasonal, chronic weed problems will help you narrow down product choices,” she said. “Choosing the right active ingredient for your problem weeds and applying it correctly are very important to weed management.”

Segars said homeowners who are not comfortable handling or applying chemical products should contact local landscape professionals. You should always follow product labels and distance applications from desirable plants to avoid injuring them.

Preemergence herbicide applications

Segars said AgriLife Extension recommends the fall preemergence herbicide regimen to begin when soil temperatures reach approximately 70 degrees. This recommendation is commonly based on annual bluegrass – a weed that germinates when soil temperatures are below 70 degrees. This generally falls in September or October, depending on where you are in Texas.

“Don’t get into the habit of relying on the same calendar date every year; that’s why we have soil temperature recommendations,” she said. “Environmental conditions can be drastically different from year to year. Some weeds will germinate later in the season but applying products in a timely manner builds up a preemergence program that stays ahead of weeds.”

Segars said soil temperature probes, even probe-type meat thermometers, can help homeowners gauge application timing.

There are weather-related websites and applications that monitor soil temperatures and even give updates via notifications, she said.

Identifying which weeds you want to control is important for choosing the correct herbicide option, such as broadleaves and grasses or perennial and annual weeds, she said. Segars recommends granular herbicides for homeowners due to ease of application.

“For best results, we generally recommend at least one application of a preemergence herbicide in the spring and fall,” she said. “These two applications, if done properly, can greatly reduce the number of annual weeds in your yard.”

Segars said some homeowners may desire to make a second or split application of preemergence, and it’s a good idea to have both a pre- and post-emergence herbicide on hand for the second application.

“Herbicides aren’t 100% effective every time, especially if you have heavy rains following application or missed the desirable timing,” she said. “Having a mixture of a pre- and post-emergence product just ensures you catch any weeds that break through your original application while they are immature.”

Watering in the preemergence herbicide immediately after application using some type of sprinkler system is recommended. Typically, granular preemergence products need one-quarter to one-half inch of water to dissolve properly, but always follow product label instructions, she advised.

“It’s easy to water in the product, especially if you have an in-ground irrigation system,” she said. “It could be risky trying to time it with rainfall. So, I would recommend using a sprinkler and figuring out how much water it is putting out and how long you’ll need to water to correctly activate the herbicide.”

AgriLife Extension has information regarding irrigation and sprinkler audits that will help homeowners determine how long to irrigate specific amounts. For more information about irrigation, visit the Texas A&M Extension School of Irrigation.

Say ‘no’ to weed and feed in the fall

Weed and feeds are a common and popular product, but Segars does not recommend using them as a fall/winter turfgrass management tool.

“We’re entering a time when warm-season grasses are slowing down in a lot of the state, and we don’t want to fertilize them too late, especially with nitrogen,” she said. “Putting nitrogen down promotes growth, and a quick freeze could cause damage.”

Segars said the last nitrogen application should be no later than four to six weeks before the average date of the first frost.

Watering as seasons change

Turfgrass needs adequate soil moisture going into winter, but as temperatures fall, Segars said homeowners should dial back on irrigation. AgriLife Extension’s Water-Wise Checklist provides good year-round recommendations that will maximize irrigation efficiency and effectiveness. 

Approximately 1 inch of water per week is AgriLife Extension’s summer turfgrass irrigation recommendation for actively growing grass. But as fall nears, Segars said rains should be enough, and that allowing grasses to visibly wilt before supplemental water applications is a good rule of thumb.

“If we are receiving typical fall rains, you can turn the system off or just water as needed until the grass goes dormant,” she said. “You don’t want to overwater, but you also want to have some moisture in the soil, especially in areas that experience hard freezes. Having some moisture in the ground will help protect them from winterkill and sustain them through winter.”

Scout now for spring preemergence application

Segars said now is a good time to scout for summer weeds like crabgrass and sandburs. Sandburs are a warm-season perennial grass known for their spiked seed pods that grow at the end of the stem and drop or attach themselves to any human or animal passersby.

Spring preemergence applications typically start when soil temperatures reach around 50-55 degrees, which can be January to March based on location and weather conditions. 

“Make note of what weeds you have now, and prepare for spring preemergence application,” she said. “Identify the weeds you have and note where they are. Make a game plan for getting your warm-season grasses off to a good start in the spring.”

How Texas became leader in safe public school pest management

2 people looking at chairs
2 people looking at chairs

AgriLife Extension school IPM specialist Janet Hurley and Wylie Independent School District IPM coordinator Tony Jacinto inspect a storage space of stacked chairs for pest issues at Wylie High School.

Anyone returning to a Texas public school this semester is safer from pests and pesticides, thanks to a host of integrated pest control practices required by the state and taught to licensed professionals by the Texas A&M AgriLife Extension Service.

Requirements for integrated pest management, or IPM, in Texas schools were passed by the Texas Legislature in 1991. IPM is the practice of controlling pests with alternatives to pesticide. It employs other methods that consider environmental safety and human health.

New laws, shift in focus

Man in coveralls

AgriLife Extension state pesticide safety coordinator Don Renchie, Ph.D., leads school IPM training in an industrial school kitchen.

By the time school IPM became law, AgriLife Extension’s state pesticide safety coordinator Don Renchie, Ph.D., and urban entomologist Mike Merchant, Ph.D., had

already been training pest control professionals in safe application for schools across the state. They were steeped in collaboration with the Texas Structural Pest Control Board — of which Merchant was a member — to develop comprehensive curricula for the training.

“There had been major incidents of human contact with pesticides in Texas schools, due to application by unlicensed applicators, leading up to passage of the IPM laws in 1991,” Renchie said. “In Texas, we decided that our children were most important, and that’s why IPM is the law here.”

Only 23 states have school IPM laws or regulations, according to the National Pest Management Association.

As provisions of the Texas’ school IPM law took effect in 1995, Renchie and Merchant shifted focus to developing a training series for the IPM coordinator. This staff position is still required at every Texas school district today. They are responsible for ensuring safe school district spaces by adhering to all IPM mandates, existing and emerging.

IPM coordinators continue to be trained by AgriLife Extension, but the agency’s training reach, evaluation systems and advanced IPM techniques help make schools safer for Texas students, faculty and staff than ever before.

A boost for school IPM training in Texas

AgriLife Extension retired entomologist Mike Merchant, Ph.D., leads school IPM training.

In 2001, a grant from the U.S. Environmental Protection Agency allowed Renchie and Merchant to hire AgriLife Extension school IPM specialist Janet Hurley, Dallas. The grant also created the Southwest Technical Resource Center for School IPM. Hurley joined AgriLife Extension as director of the center, whose education materials live on as part of AgriLife Extension’s comprehensive teachings. Her work to organize school IPM training across Texas dovetailed with a previous grant that Merchant and Renchie were awarded to create “The ABCs of IPM” video series. The series is still taught to IPM coordinators as part of state requirements.

By that time, she said, roughly 80% of Texas schools had fallen out of compliance with state IPM standards. Additionally, a more streamlined system for professional training was needed across the state.

Seeking solutions

“When I got there, it was six hours of training, pat ‘em on the back and ‘see ya later, bye,’” Hurley said. “I said ‘No wonder the schools look like deer in headlights with IPM standards.’ And my bosses said ‘well that’s why we hired you. Now what are you gonna do about it?’”

She began to develop — with Merchant, Renchie and EPA grant colleagues in New Mexico and Oklahoma — one-day and two-day school IPM trainings, which emphasized hands-on work. It is the same model AgriLife Extension uses to deliver emerging school IPM information today at the IPM Experience House.

While Hurley worked to broaden AgriLife Extension’s reach, Renchie and Merchant could still lead school IPM trainings and focus on expanding responsibilities of entomology and pesticide safety — the overarching areas of urban pest management statewide.

Hurley created a map of Texas’ roughly 1,030 school districts and began reaching out to them with what she calls “the gospel of IPM.” By 2008, she built enough enthusiasm among Texas schools to form the nation’s first statewide association of school IPM professionals — the Texas IPM Affiliates for Public Schools. Before the group disbanded, it welcomed more than 1,000 attendees to its annual meeting between 2009 and 2014.

These early efforts all contributed to making AgriLife Extension a driving force in the unique success of IPM in Texas schools and beyond.

School IPM impact

people

Janet Hurley leads a school IPM training for school district IPM coordinators in North Texas.

Since 2002, AgriLife Extension has offered 234 full days of school IPM training classes and reached 5,861 participants from 1,638 school districts. Hurley’s efforts alone include 265 personal site visits to Texas school districts. She assists with compliance issues and helps IPM programs prepare for inspections and awards.

As a result of these efforts, more than 20 Texas school districts are winners of the IPM Institute of North America’s national IPM Star award — more than any other state.

Among the state’s recognized districts is Wylie Independent School District, whose IPM coordinator is Tony Jacinto. The district failed to meet state IPM standards in 2016, before Jacinto heard about Hurley and AgriLife Extension from colleagues in another district.

“At that time, I had no experience with IPM and asked Janet to come teach me the ABC’s,” Jacinto said.

By 2019, Wylie ISD had become one of Texas’ national IPM Star districts, and Jacinto had scored 103 out of 100 during the award audit — above a perfect score.

Hurley is also a strong supporter of the IPM Star award, which exceeds even Texas’ standards for IPM.

What’s next

Today, Renchie continues to train pest control professionals for licensing, and Merchant retired in August following more than 30 years with AgriLife Extension.

“It’s widely recognized that IPM adoption benefits health and the environment,” Merchant said. “These accolades and increased compliance numbers show that Texas schools are safer as a result of AgriLife Extension’s reach and work.”

Meanwhile, in conducting 75 regional two-day trainings and 84 one-day trainings since 2002, Hurley remains the most active coordinator of school IPM training in Texas, and likely in the U.S., Merchant said.

Janet Hurley“She has an almost encyclopedic knowledge of Texas school districts and their IPM personnel,” he said. 

Through AgriLife Extension, Hurley also maintains a school IPM hotline and the Texas School IPM website, providing learning resources and training information. Her industry newsletter, School Pest News, is in its 137th edition since 2002, and it circulates to a readership of about 1,600 per issue. She is active in the International IPM  Symposium steering and awards committees and is on the National School IPM Steering Committee.

Over the next year, AgriLife Extension will expand IPM offerings with its public Residential IPM course series, which covers general integrated pest management for homes.

Hurley will propose a comprehensive research initiative to determine rat presence in Texas as well as the types of communicable diseases they carry, which remains largely speculative, she said.

“We’re just going to keep on building,” she said.

Training for school staff on proper cleaning procedures.

This is a reminder that the OSHA Haz Com standard applies to workers, as does the respirator standard when an employee is required to use a respirator (including N95 filtering facepiece respirators) in some aspect of their job. Texas School fall under a requirement for all Texans to be trained when using chemicals, this includes cleaning

A new NIOSH webpage, Hazard Communication for Disinfectants Used Against Viruses, provides information on health hazards that could be caused by cleaning products and disinfectants. Also included are recommendations for barriers and respiratory protection that workers can use to protect themselves from these hazards. More at https://www.cdc.gov/niosh/topics/disinfectant/default.html

Review EPA Guidance on Indoor Air and COVID-19

The Environmental Protection Agency (EPA) has a new website addressing indoor air and the coronavirus, including information about ventilation and HVAC systems. The EPA also has a list of frequently asked questions.

Additional COVID resources provided by the National Pesticide Safety Education Center (NPSEC) and National Pesticide Information Center (NPIC) in effort to have everything in one place.

 

Finally, the American Federation of Teachers held a webinar earlier this month.  The slidedeck link will take you to the recorded webinar that you can share with your staff.  

 “Cleaning and Disinfecting in Schools During a Pandemic” was held on August 12th.  This was their first webinar in their Road to Reopening Schools designed to discuss promising nuts and bolts strategies for a return to brick and mortar school buildings based on the best available and most current scientific evidence, as outlined in AFT’s ”Reopening School Buildings Safely” recommendations. This report, details the very basic conditions needed to open schools,-critical safety and health guidelines, and instructional considerations. For this four-part series, we will be joined by local leaders, district administrators, and experts in their respective fields.  

If you missed the live session, you can access our first webinar on Cleaning and Disinfecting on demand here: https://event.on24.com/wcc/r/2563524/BE6CF9C04A945B5BE815E69B2B2A2B8F.   Below is the description and list of guest speakers for this program.

Cleaning and Disinfecting

The goal of this webinar was to provide the latest information on the appropriate process for cleaning and disinfecting during the pandemic, why is it important and where does it fit in the interventions to keep students and staff safe. Discussion will include the steps to achieve disinfection and sanitizing during a pandemic, the elements of a cleaning and disinfecting protocol and the roles and responsibilities of staff and students in the cleaning and disinfecting process.

SPN: School reopening does any of this impact my IPM and IAQ program?

As everyone is trying to figure out how to educate children during the COVID-19 pandemic, the question on everyone’s mind is how to do this by keeping schools clean? The guidelines from CDC, For a Safe Return to School in Fall 2020 and the Texas Education Agency’s two documents Public Health Planning Guidance and School Reopening Guidance Summary give some advice on how to open your school; however, it’s limited in the actual directions of what, where, and when to clean. In an IPM program the first step is to understand the pest you are dealing with and come up with your solutions. For us it’s understanding the virus and how it spreads, to develop a plan on which areas of the school need deep cleaning everyday or regular cleaning that has been done by custodial staff in the past. Many of the steps outlined can seem extreme, but it all depends on where you are located and what is going on in your community as relates to COVID positive cases on what you need to implement.

The Virus

Coronaviruses are a large family of viruses that are known to cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The novel coronavirus (COVID-19) is a new strain of coronavirus that has not been previously identified in humans, which has led to a variety of changing information. COVID-19 is thought to spread mainly through close contact from person-to-person. Some people without symptoms may be able to spread the virus. It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes. This is not thought to be the main way the virus spreads, instead it is those airborne droplets we exhale every minute of the day. Check out this article, COVID Analysis, for a visual on how the virus can be spread indoors.

How to Protect Staff and Students

In all the guidelines that are being offered to help schools open, the one term I feel most have lost sight of is “mitigate”. The definition of mitigate is to make less severe, serious, or painful. In most cases this means good cleaning practices, social distancing (keep out my personal space) and wear a face covering over the mouth and nose. During flu season, school nurses and administrators remind kids to wash their hands, cover their cough, stay home if you are sick. These are the same principals we all need to remember with COVID.

The larger challenge for schools is ensuring everyone has enough personal space. Instead of four students sitting at a lab bench in chemistry class – it will be one student. Cafeterias will no longer serve buffet style, instead it will be served in the classroom, or box style with limited human contact.

One of the main pathways’ researchers have determine COVID is spread indoors is through those heavy droplets we exhale and then “float” in the air. One of the recommendations is to open windows and doors. There are two reasons we typically do not do that in TX; 1) it’s hot and 2) what pest will fly or crawl in. Instead, think about the ventilation system on each campus, make sure filters are changed, vents are clean, and more importantly the return air area is clean as well. If the weather permits, let kids outside to play or read. Also make sure staff understands that in the teachers lounge they too must follow all the guidelines as well.

Cleaning, Disinfecting, and Sanitizing

These three terms have been used so often and a lot of people believe that by doing these processes you can completely kill the COVID virus. At the same time, many believe that if you engage in these processes that you can keep the COVID virus away for days, which you cannot. Schools are being asked to mitigate the spread of the virus, not eradicate the virus. Let us look at the three terms:

  • Cleaning is the process of removing unwanted substances, such as dirt, infectious agents, and other impurities, from an object or environment.
  • Disinfection the process of cleaning something, especially with a chemical, to destroy bacteria.
  • Sanitize make clean and hygienic; disinfect

The Department of Family and Protective Services and Department of State Health Services define sanitizing. They recommend for the sanitizing process to be effective; you must follow these four steps in order:

  1. Washing with water and soap at least 2 minutes for hands
  2. Rinsing with clear water.
  3. Soaking in or spraying on a disinfecting solution (at least two minutes). Rinsing with cool water only those items that children are likely to place in their mouths.
  4. Allowing the surface or article to air-dry.

DSHS has this DYI- disinfecting solution:

  1. One tablespoon of regular strength liquid household bleach to each gallon of water used for disinfecting such items as toys and eating utensils (high touch items) 
  2. One-fourth cup of regular strength liquid household bleach to each gallon of water used for disinfecting surfaces

When it comes to cleaning materials the next big question is the use disinfecting wipes by the staff. While these are convenient, cleaning wipes require some common sense be used if you choose to use these in your school district. First, they are pesticides under the U.S. EPA Federal Insecticide Fungicide Rodenticide Act (FIFRA). Under FIFRA pesticides must have two statements; 1) signal word (Caution, Warning, Danger) and 2) child hazard statement (keep out of reach of children), these requirements are to alert the user that these products require personal protective equipment and cautionary use around children.  Second, using these cleaning wipes for a quick cleanup is great, but to keep things like door handles, common use items (fridge handles, faucet handles), and in food preparation areas use the sanitation steps above. Should you wear gloves when using these wipes? If teachers and staff are going to use these daily to wipe down the head phones, keyboards, desk tops, paint brushes, microscopes, etc. (items the kids touched) then yes, they should wear a pair of disposable gloves that way they are protected.  Our hands are very porous, hence why it’s so easy to transfer the cold and flu, but we also must protect ourselves from cleaning solutions entering our system as well.

Many administrators have been introduced to the EPA List N: Disinfectants for Use Against SARS-CoV-2 (COVID-19) and many IPM Coordinators are now being asked if the products used on this EPA list fall under the school IPM program?  The short answer is no – in TX, the school IPM rules only pertain to pests that harm buildings, turf, humans, or other living things. The custodial cleaning and disinfection products that are used in schools have always been registered as pesticides under FIFRA. No matter the products you select you still need to train staff on the proper use of these products which includes reviewing the Safety Data Sheets. While that is not part of the school IPM rule, it is part of the Right to Know and Hazard Communication acts that require employers to ensure their employees are adequately trained.

Do I need to post? No, not unless one of the products you use require you to do so. If you are doing deep cleaning, using a misting type device, or some other type of cleaning that requires the employees to be protected, then you might want to think about notifying employees of these efforts. Again, read that pesticide label, the label is the law.

Finally, all cleaning and disinfecting products can be harmful to humans if used improperly. Improper use can be as simple as not wearing the right personal protective equipment to spilling a bottle of cleaner. If the product you are using has a signal word and keep out of reach of children that is the first step to understanding personal use protection. While we all want schools to open, we must also understand that in these indoor environments we must also be cautious about how many products we are using inside each room each day. In this white paper by Beyond Pesticides, The Intersection of Pesticides and the New Normal under Coronavirus they discuss many of the ways students and staff can be harmed by too much use of common cleaning products and hand sanitizers.

In August I will be working with EPA, TASB and others to offer some additional webinars on this topic and back to school pests in general, so watch your email for those announcements.

2. The Longer-Term Effectiveness of Home Asthma Interventions

Tuesday, June 23, 2020 at 2:00 pm EDT

Since 1980, the biggest growth in asthma cases has been in children under 5.

Research supports that community health worker led healthy homes interventions improve asthma outcomes among children. But how effective are these programs with adults, and what is the longer-term effectiveness of these asthma interventions? This is a key consideration when measuring the economic impact of asthma intervention programs. Two researchers will present their findings from long-term multifaceted home environmental asthma intervention projects with older adults and children in diverse low-income households.

3. EPA Advises Facility Operators to Prepare for Hazardous Weather Events

2010 rains, flood waters submerged a Cheatham County school bus, vehicles, and Kingston Springs Elementary School

With June marking the start of hurricane season in the Atlantic Ocean and Gulf of Mexico, the U.S. Environmental Protection Agency (EPA) reminds facility operators of requirements for preventing, minimizing and reporting chemical releases. Facility operators are obligated to maintain safety, minimize releases that do occur, and report chemical or oil releases and discharges in a timely manner, as required under the Comprehensive Environmental Response, Compensation and Liability Act and/or the emergency planning provisions of the Emergency Planning and Community Right-to-Know Act and/or the National Oil and Hazardous Substances Pollution Contingency Plan.

“The people of Texas and Louisiana know that with the environmental, economic, and recreational benefits of the Gulf Coast also comes the responsibility of preparing for hurricanes and other hazardous weather,” said Regional Administrator Ken McQueen. “As with every hurricane season, EPA encourages coastal businesses to prepare their facilities and employees for whatever the weather might bring.”

Unlike some natural disasters, hurricanes and tropical storms are predictable and usually allow facilities to prepare for potential impacts. EPA reminds operators of some basic steps to prepare for hazardous weather:

  • Review procedures for shutting down processes and securing facilities appropriately—especially hazardous chemical storage—or otherwise implement appropriate safe operating procedures.
  • Review updated state-federal guidelines for flooding preparedness, available here.
  • Assure all employees are familiar with requirements and procedures to contact the National Response Center in case a spill or release occurs.
  • Review local response contacts, including Local Emergency Planning Committees (LEPCs) and State Emergency Response Centers (SERCs). A list of these contacts by state is available here.

SPN: Summer work in the age of COVID-19

No matter where you live these days you have been affected by COVID-19.  Some of us can work from home, while others have been reassigned and some have not been able to work.  However, as June 1st approaches many of us will be returning to our work environments with new social distancing guidelines.  These guidelines also require all of us to change our behavior on how we interact but also how we will need to implement strict cleaning procedures.

So how do you maintain your IPM program and follow these guidelines?

As you and your staff regain entry into your buildings it’s important to understand that you might have a variety of pest control issues.  While the humans have been away the mice, roaches, ants, bats, and myriad of other insects have had a free rein of your buildings.  As staff start to enter your buildings this is a good time to reinforce how they need to report these pest findings.  Making sure that staff doesn’t use their own chemical controls is still essential to ensuring your IPM program stays in compliance.

Now is a good time to conduct those facility inspections.  Finding those vulnerable areas where pests enter your buildings will aid in making sure you don’t have bigger problems in the fall when everyone comes back to school.  One of the resources we developed several years ago was the IPM Calculator that allows you to conduct a full inspection on your school campuses and give them a score.  Once you set up an account, you can access a PDF inspection checklist and then once you have inspected your campus, you will input that data into the system.  Once everything is entered from that campus and you hit submit, our system will then calculate the risk your building has for pests.  Nothing will get an administrator’s attention is when you give them a score of C, D or F on their building.  Or knowing that you have buildings with high scores (A and B) so that you know which campuses need extra attention.  Remember inspections are the backbone of any IPM program and can help you put into place exclusion methods to keep the pests outside.

Moving outside watch your perimeter for wasps, hornets, bees, and yellowjacket nests.  Texas is home to over twenty different species, and they are largely beneficial.  However, it is important to watch the eaves and soffits of your buildings to keep from nests becoming problematic.  Simple steps like using a webster to knock down paper wasp and mud dauber nests are something even a custodian can do.  Watching for bees and yellowjackets nests is also essential, these insects tend to build their nests in cracks and crevices in hidden areas behind large bushes.  Typically, they go unnoticed for months and become a problem in September and October, so now is the time to train custodial staff to be aware of their surroundings.

The other outdoor insect that can move indoors and thrives outdoors is ANTS!  But don’t despair we have a new online course Ants 101 that can educate about the most common ants of TX and give you CEU credits as well.

Hands and Face

The blue shading it to remind you that everytime you touch a surface you are transferring germs

If you have ever attended a CEU workshop, school IPM training with AgriLife Extension or pesticide safety training with Dr. Don Renchie then you have heard him say this; “Hold out your hands, now say with me these are the nastiest things on your body.”  Hands can transmit all sorts of germs, but in our pesticide safety classes we also discuss that hands can also transfer pesticide chemicals as well.  One of the exercises we have used in our trainings is apply a dye that when the lights are turned off it shows how we transfer from objects to our bodies.  I found this video from the BBC that uses this dye to show how coronaviruses are spread.  Remember the common cold virus is a coronavirus so when you practice good hygiene you are protecting yourself and your family.  The other video I found is something you can share with staff, teachers, and kids it’s on how germs spread.  This is a good reminder about all the nasty things we encounter.

Finally, I would like to direct to the Texas Association of School Boards website on COVID-19.  This week I participated in webinar from the Risk Management group on How Will COVID-19 Impact Summer Maintenance Work? While most of us leave this topic to administrators I highly recommend you sign up for their newsletters and check out their website as well.  I have always promoted the risk manager in your district as an important part of your IPM program. Here is your reminder to go introduce yourself to that person and take a few minutes explaining your IPM program to them.  They can be your biggest champion as what happens with pests can impact the entire district as well.

One last item: I am planning to host a couple of webinars in June where you will have a chance to ask our experts on insects and turf management.  Keep on your eye on your email and feel free to follow me on social media the Facebook page on school IPM is where I post a lot of information that I don’t put in the newsletter.  Don’t Facebook then you can find me on Twitter @JanetDHurley or Linkedin all three accounts are linked to my social media postings.

Remember we are here for you, please let me know how we can help your district as you return back to work.

Warm weather means more ticks: Texans, take care outdoors

As the warm weather draws more and more Texans outdoors, Texas A&M AgriLife Extension Service experts want people to be aware of the danger ticks pose.

Ticks are blood feeders in all life stages and can transmit pathogens that can lead to disease transmission,” said Sonja Swiger, Ph.D., AgriLife Extension entomologist, Stephenville.

“While we do see tick-borne disease here in Texas, our rates are much lower than many other states,” she said. “However, people need to be aware and vigilant. That is the only way to stop them.”

Where ticks are found

Swiger said since ticks can’t fly, the only way to be exposed to them is by entering their space or by catching them from an animal that has picked them up.

Unfortunately, ticks can be found pretty much anywhere.

“Aside from if you’re in a concrete jungle, there can be ticks,” Swiger said. “They can be in overgrown brush, a field, forest, park, tall grasses and anywhere there is wildlife.”

Given that many people have been inside more than normal due to COVID-19 and social distancing, Swiger said we do not yet know what that will mean, if anything, when it comes to ticks. Most ticks only live outdoors unless they hitch a ride into a home on a human or animal host.

“Since people haven’t been outdoors as much, that may mean some areas haven’t been mowed in a while or brush hasn’t been cleared. We’ve also seen wildlife coming into some urban areas more during these periods while people have been staying indoors. Will that increase exposure? We just don’t know yet, so people need to take precautions.”

Ticks are something people need to be aware of year-round, although as the weather warms their populations swell, typically peaking in the summer and then declining in the fall. Swiger said we are at the start of their “plentiful season.”

Tick awareness and prevention

As Lyme Disease Awareness Month ends and many people plan to be outdoors for the Memorial Day weekend, now is a good time to review how to protect yourself and your family from these arthropods.

Lyme disease is the most common tick-borne disease, with an average of 30,000 cases a year reported to the Centers for Disease Control and Prevention. Lyme disease can also affect pets. There are numerous other diseases such as Rocky Mountain spotted fever and tularemia that ticks can transmit to people. Ticks are also responsible for often-deadly diseases in livestock such as cattle fever.

There are 11 common species of ticks found in Texas. The black-legged tick, brown dog tick, Lone Star tick, Gulf Coast tick and American dog tick are the species the average person is most likely to encounter. The TAMU TickApp for Texas and the Southern Region is a helpful tick identification and resource tool.

Ticks typically like to latch on to people’s head, hair, chest, armpit, groin, waist and back of the knees, so be extra vigilant when checking these areas. Headwear and light-colored clothing that protects as much skin as possible is also a good idea if you’ll be outdoors where ticks are present. Pants should be tucked into boots to minimize the odds of bringing an unwanted bloodsucker home.

“Check yourself after being outdoors,” said Swiger. “Also check your pets if they have been outdoors.”  

Swiger said people who let their pets sleep in their bed with them need to be extra vigilant.

Around your home, keep lawns mowed, brush trimmed and weeds whacked. Be especially diligent about the areas around swing sets, sand boxes and children’s play areas.

Since rodents are part of the tick-borne disease cycle, eliminate places they like to live and hide. Try to avoid having brush piles and keep any building materials and gardening supplies off the ground.

If a tick is found, it can be removed with tweezers. Grasp the tick as close to the head as possible and pull straight out. If the head breaks off under the skin and cannot be removed, or if any pain, lesion or a rash develops, contact a doctor. If fever, headache, joint pain, muscle pain or swollen lymph nodes occur within 30 days of a tick bite, you should also inform your doctor.

“We don’t want this holiday weekend to be a perfect storm for ticks with the warmer weather, a lot of people outdoors and perhaps more overgrown brush than usual,” Swiger said. “I don’t want people to worry, I just want people to be aware.”

Stinging caterpillar season starts: AgriLife experts warn stinging caterpillars can cause contact rashes, painful reactions

As the weather warms up and people begin spending more time in their yards, parks and forests, more people will be coming home with a rash or bug bite.

However, Texas A&M AgriLife Extension Service experts say before you blame a flying insect or a poisonous plant for a skin ailment, you may need to consider another culprit – stinging caterpillars.

“Spring foliage has brought on an abundance of caterpillars, a few of whom carry irritating or even venomous hairs,” said Janet Hurley, AgriLife Extension integrated pest management for schools statewide specialist, Dallas.

“We normally have fact sheets available for schools this time of year, but with most children out of school due to COVID-19, we wanted to make sure parents are aware that there are stinging caterpillars in Texas, what they look like, and how to avoid them,” she said.

Stinging caterpillar species include the buck moth caterpillar, spiny oak slug caterpillar, hickory tussock moth caterpillar, saddleback caterpillar and Io moth caterpillar.

Perhaps the most painful caterpillar in Texas is the southern flannel moth caterpillar, also known as the asp or puss caterpillar. An encounter with a puss caterpillar is very painful and may even require a trip to the hospital, according to AgriLife Extension experts.

What stinging caterpillars look like

Hurley said she recently received her first tussock moth caterpillar question – confirming that just about every species of stinging caterpillar has now been spotted in our state.

“A good rule of thumb is if a caterpillar looks ‘fuzzy’ — don’t touch it,” said Molly Keck, AgriLife Extension specialist in integrated pest management and entomologist, Bexar County.

Although many fuzzy caterpillars are not dangerous, do not pick up a caterpillar unless you are sure it is not of the stinging variety. The puss caterpillar, for example, looks deceptively soft and can be especially tempting for children to want to pick up or “pet.”

“These teardrop shaped caterpillars look touchable, but they are not,” emphasized Wizzie Brown, AgriLife Extension specialist in integrated pest management for Travis County. “Asps have spines attached to venom glands that can lead to a nasty sting, rash and other issues.”

Caterpillar sting symptoms and treatment

“Since these caterpillars tend to hide, you may not even know you’ve encountered one until you feel the sting,” Hurley said.

If you are stung, you may feel immediate pain and reddish colored spots may appear where spines entered the skin. Some people may not feel pain until several minutes after they are stung, while others can experience intense throbbing or radiating pain. Other people may not feel much discomfort, and a red rash may be the only telltale sign.

Brown said different people respond to caterpillar toxin differently. “Some people may have a more severe reaction than others, and where on your body you are stung and the thickness of that skin can affect your reaction too.”

If the caterpillar is still on you, immediately brush it off if possible and then use tape to remove the spines that may still be in your skin, Brown said.

Washing the area with soap and water and applying an ice pack to the sting may offer some relief, and an oral antihistamine may help to relieve itching. Over-the-counter insect sting and bite relief products can also help.

“The pain often goes away within an hour,” said Mike Merchant, Ph.D., AgriLife Extension urban entomologist, Dallas.

Other symptoms after a sting can include nausea, vomiting, headaches, respiratory stress or shock. Since reactions to the toxins from stinging caterpillars can vary, seek medical advice or treatment immediately or go to an emergency room if you are concerned. Merchant also stressed that any contact with eyes or an allergic reaction to a sting requires immediate medical attention.

Stinging caterpillar habitat

“You are more likely to encounter stinging caterpillars when they leave their host plant in search of a spot to pupate, which is currently happening with many caterpillars,” said Keck. “They aren’t aggressive and won’t come after you, but they can drop from trees.”

Keck has reported sightings of both buck moth caterpillars and tussock moth caterpillars in the Bexar County area already this spring. Texans statewide need to be on the alert and keep an eye on trees and shrubs for caterpillar development, which typically occurs now into the fall.

Some common tree hosts are apple, basswood, cherry, dogwood, elm, maple, plum and oak, which is a favorite of the buck moth caterpillar. Some stinging caterpillars may even be found on crops such as corn.

“Adult puss moths emerge in late spring or early summer to lay several hundred eggs on favored host trees,” said Merchant. “Caterpillars may also be seen feeding on dwarf yaupon and other shrubs. One to two generations occur each year, though southern flannel moth caterpillars tend to be more common in the fall.”

Pest management

Avoid stinging caterpillars by not sitting under trees and wearing long sleeves and pants outdoors, although even that is no guarantee of protection.

“I had the misfortune of getting an eastern buck moth caterpillar on my pants the other day and accidentally brought it inside,” said Keck. “When I rested my hand on my leg, I encountered the hairs/barbs and it didn’t feel good. It itched and left an uncomfortable feeling on my thumb for a couple hours.”

Keck said there isn’t much you can do about managing these caterpillars until they all pupate and go away. You don’t need to worry about harm to your garden however, as stinging caterpillars typically do not do enough feeding to harm plants.

If you have large populations of stinging caterpillars and decide you need to try to manage them, you can try Bacillus thuringiensisvar. kurstaki, BTK. However, this will also kill all the non-stinging or “good” caterpillars, which are an important food source for songbirds. You may also look for a pesticide with active ingredients such as spinosad or azadirachtin, which are naturally derived products.

Merchant said puss moth caterpillars can also be controlled when they become abundant by spraying with a residual pesticide such as permethrin, cyfluthrin or similar sprays labeled for control of caterpillars on ornamental plants. 

“The best solution to dealing with stinging caterpillars may just be educating adults and children on what these caterpillars are, what they look like, and the importance of not touching them with bare hands,” concluded Merchant.

SPN: While the humans are away the pests will play

Since March 23, 2020, most TX schools have been closed due to the COVID-19 pandemic. However, during this time the most common pests of TX have not taken a break from your campuses. Even though our AgriLife Extension offices are closed we are still working from home and insect questions are still coming in. Over the past month we have seen an increase in stinging caterpillars mostly in the San Antonio and Hill county region of the state. There will be a special story on that coming later this week.

In the meantime, this is issue is to remind you of some of the important pests you need to consider and what you will need to do when schools open again in the fall.

A bee swarm consists of a queen bee surrounded by her colony of worker bees. Children and others should be warned to keep away from such swarms until it can be removed.

Honey bees (Apis mellifera) are swarming right now.  What can schools do when they show up? According to our Entomologists you have three choices: 1) leave them be, 2) have a beekeeper pick them up, or 3) take them out with soapy water. 

Wait aren’t bees protected? Why Kill Bees?

If you can’t find a beekeeper to remove them in a timely manner, extermination quickly eliminates any risks to kids, pets, or others of stings (instead of waiting 1-3 days for them to move) and reduces the chance that the swarm will enter and start nesting in a school building (an expensive problem).   A little-known fact is that most wild bees are Africanized and not a good addition to a school campus.  Also, wild (feral) honey bees are not endangered. Check out this article from Dr. Mike Merchant’s website on bees.   https://citybugs.tamu.edu/factsheets/biting-stinging/bees/ent-3002/  Not sure where to find a local beekeeper then check out the Texas Apiary Inspection Service. You can find a list of beekeepers, by county, who may do removal in your area. https://txbeeinspection.tamu.edu/bee-removal/

oriental cockroach (Blatta orientalis)

Oriental cockroach (Blatta orientalis) Multiple Life Stages

The American Cockroach (Periplaneta Americana), Oriental cockroach,(Blatta orientalis) and the  Smokybrown cockroach (Periplaneta fuliginosa) are common invaders of vacant structures.  These “outdoor” cockroaches prefer warmer climates and moist surroundings and can thrive year-round in these conditions. The American cockroach is common in city sewers and basements, particularly around pipes and drains. The smokybrown prefers tree holes, loose bark, and mulch. The Oriental cockroach is common outdoors and lives in warm, damp shady areas near the ground or any area containing natural debris. Each species can build large populations if uncontrolled and can spread bacteria by contact. Finding them inside often indicates a need to pest-proof external entryways or looking into floor drains that may have not seen any water since early March. Ignoring these pests can be bad news when students and staff come back in August. 

In TX, we have several species of bats, the most common one school IPM coordinators encounter is the Mexican free-tailed bat (Tadarida brasiliensis).  The Mexican free-tailed bat, mate in the spring (now). Fertilization and fetal development follow, and pups are generally born in the late spring or early summer (mid-April to June). By late summer, the pups can fly and feed on their own. Which means if you have a colony of bats living in one of your school buildings the window to do exclusion work is about to close.  However, maintenance staff need to be monitoring campuses for the occupation of bat colonies, identify where they are entering and exiting the structure.  These areas will need to be sealed up in the fall in order to prevent the bats from returning to your campus building next year.  Something to consider before you seal up the building for bats is to install a bat house close to the campus.  Bats are creatures of habit and will return to the same roost year after year. Unfortunately, in the South, some bat species have found this area habitable all year long although their migration patterns may require them moving from one part of the state to another, they may not fully leave your buildings.  So, the bat house is a way to allow them to have a safe place to live, but not occupy the building structure where people can be exposed to them.

Exterior inspections can help coordinators and pest management professionals find potential pest problems before them come inside.

Because fire ants (Solenopsis invicta) may present a hazard to children who are allergic to their venom, fire ant control should be made a top priority around athletic fields, playgrounds and classroom buildings. Emphasize year-round suppression of fire ant activity in landscapes in and around buildings because fire ant mounds are usually located outdoors. Fire ant baits provide excellent control and are considered a preferred treatment. Where fire ant mounds are not numerous, individual mounds may be treated with baits or contact insecticides according to label directions. Over the past month I have heard many districts are forgoing their spring treatments since no one is around.  This is alarming because if you don’t treat now and again in the fall, the chances are this ant species will be a common visitor to all your outdoor fall events.  Now is the time to put out your spring bait for fire ants.  Visit our website dedicated to Red Imported Fire Ant to find treatment methods, how to calculate bait costs and must more.

Mosquitoes are of concern in the school environment because many species are painful biters and/or are capable of transmitting diseases. In the United States, the threat of developing encephalitis from mosquitoes is far greater than the threat from other mosquito vectored diseases. Encephalitis, meningitis and other diseases can develop from the bites of mosquitoes infected with certain viruses such as West Nile, St. Louis encephalitis, LaCrosse (California) encephalitis, and Eastern equine and Western equine encephalitis. An effective control program will not eliminate all mosquitoes but will keep the population at a reasonable level and will reduce both nuisances and the risk for mosquito-borne diseases.

While many rely on their local health departments to provide vector control in their area, the fact is most mosquito programs don’t come on school property.  The focus of the vector control departments is to prevent mosquitoes via larviciding and then spraying products that kill the adults.  Larviciding is the regular application of microbial or chemical insecticides to water bodies or water containers. The aim of larviciding is to reduce the adult population of mosquitoes by killing the aquatic immature forms, so that fewer will develop into adults.  This is something every school district in TX should be considering as there are so many areas within our school districts that mosquitoes can breed and live.  Again, this is something that if you tackle now you won’t have as many of these “friends” come fall.  And by the way there are some cool mosquito traps that use a combination of larvicides and adulticides that can be placed around your campuses that work 24/7.  Check out this story from last November on mosquito control in a California School.

Finally, this newsletter would not be complete without discussing the least desirable pests: mice and rats. If you have been watching the news or social media these critters have taken front stage in many urban areas.  If you do nothing else while students and staff our out of your schools is to exclude or seal up as many entry points as possible.  This is the perfect time to attack those areas that you normally don’t have time to do.  In areas that you have had high populations make sure you are baiting as well.  If you search for City of New Orleans and rodents, you will see what my friends are doing which is baiting heavily in areas that the rats are searching for food.  Mice and rats are opportunistic, and they will eat anything even their young, but I have also seen them eat crayons, paper, or more than likely the food that the teacher left in their classroom back in March. 

One last item before you go, our county agents have been reporting sightings of true armyworms in hay fields.  I mention this as you will want your grounds people to be on the alert for fall armyworms later this year.  Check out this newsletter posting from 2018 on this topic

Remember we have plenty of resources to help you out to establish those threshold levels or help you decide what options you have.  Visit the School IPM Website for more information on the most common pests we see in schools. 

I would like to thank the team of community entomologists: Dr. Mike Merchant, Dr. Robert Puckett, Dr. Sonja Swiger, Molly Keck and Wizzie Brown for helping me figure out what pests to feature.  Remember we are all here to help you.
