An Update on School IPM

Leave a reply

Recently members of the NYS IPM Program met in Albany as part of a joint meeting of the Clean, Green, and Healthy Schools Steering Committee and the Statewide School IPM Committee.

NYS IPM Educator Joellen Lampman demonstrates ‘dragging for ticks’ as a method to determine tick presence on school grounds.

Clean, Green, and Health Schools is coordinated by the NYS Department of Health and helmed by Dr. Michele Herdt. Their purpose is to promote a healthy learning and working environment in our state’s schools, both public and private.

From their page at health.ny.gov:

 

What is a School Environmental Health Program?

School environmental health is the way the physical environment of school buildings and school grounds influence the overall health and safety of occupants. School environments can impact occupant health, absenteeism, employee/student retention and satisfaction, academic performance, and operation costs for the school. Children are more vulnerable to environmental exposures because they eat and drink more, relative to their body weight, than adults, their body systems are still developing, and their behaviors put them at greater risk, such as hand-to-mouth action and playing on the ground.

Unfortunately, gaps in outside doors are a common problem in public buildings and offers easy access to rodents.

The New York State Clean, Green, and Healthy Schools Program is designed to help all school employees, volunteers, students, parents, and guardians contribute to improving their school’s environmental health. The program has been developed by a multi-disciplinary Steering Committee to help schools improve their environmental health through voluntary guidelines. Schools that participate in this program gain the opportunity and knowledge to create schools with better environmental health. The program provides information for all school occupants on policies, best practices, tools, knowledge, and resources in nine main areas:

  1. Indoor Air Quality;
  2. Energy and Resource Conservation;
  3. Integrated Pest Management;
  4. Mold and Moisture;
  5. Chemical and Environmental Hazards;
  6. Cleaning and Maintenance;
  7. Transportation;
  8. Construction/Renovation;
  9. Water Quality.

Last year, they began a free pilot program to create safer and healthier learning and working environments for all students and staff across New York State. We are looking for schools that would like to be a part of this pilot program and improve the environmental health of their school through low or no cost actions.

As of October, 2018 they have ten school buildings involved, and hope to have at least 10% of NY schools enrolled in the program by 2024.

The NYS IPM Program is glad to be part of the efforts.

Later in the morning Vickie A. Smith and David Frank from the NYS Dept. Of Education shared their work with charter schools, engaging the participants in the joint meeting with ideas on how to better reach this growing segment of education in NYS.

While we have sought to find a way to work with non-public schools in NY, charter schools are also another subset with their own particular concerns.  Like many non-publics, some charter schools operate in rented buildings (some are indeed buildings owned by a public school), and therefore it is not always clear who is responsible for environmental issues school staff face. Charter schools have multiple authorities to report to depending on their location: The NYS Board of Regents, SUNY trustees, NY City Department of Education and the Buffalo City School District. Many students in charter schools are ‘at-risk’. 80% are considered economically challenged, or have disabilities or language barriers.

Charter schools are considered public schools and must comply with many of the same rules. Our day of discussion proved there are plenty of opportunities to increase the use of IPM in all schools in NY State.

Geese on school grounds has become a growing pest problem as resident geese populations increase.

Staff of the NYS IPM Program finished out the day’s meeting with a look at Don’t Get Ticked NY efforts. This included sharing the Ticks on School Grounds posters.

The ABCs of Ticks on School and Childcare Grounds

Leave a reply
“The more we hear people telling us their tick stories, the more we’re realizing that much of the information that a majority of people “know” about ticks is just wrong enough to leave them at risk.” – Dr. Thomas Mather, TickEncounter Resource Center

Tom Mathers, a personal tick education hero of mine, recently created #JustWrongEnough to cover those areas that people think they know, but puts them at risk. He used “ticks jump out of trees” and “ticks die in the winter” as examples. I have also heard many #JustWrongEnough tick beliefs that put people and kids at risk for tick-borne diseases.

I won’t comment on people who believe they are safe because they have never had a tick on them.

We won’t get into how much time a tick needs to be attached before transmitting disease-causing pathogens (I consider the 15 minutes needed from attachment to transmission of the Powassan virus to deem this argument moot anyway).

And don’t get me started on the correct way to remove a tick. I covered this in my 2016 blog post, It’s tick season. Put away the matches., and have found no evidence to convince me that pointy tweezers are not the superior method.

Let us focus, then, on #JustWrongEnough beliefs that are important to school and childcare grounds.

#JustWrongEnough 1: All ticks carry Lyme disease.

The risk: Individuals, and their doctors, might not know what diseases they might have been exposed to and lead to a misdiagnosis.

Below it, smaller drawings of the larva, nymph, and male American dog tick. Brackets showing which group of diseases are carried by which ticks. The blacklegged tick carries Lyme disease, anaplasmosis, babesiosis, powassan virus, Borrelia miyamotoi, and ehrlichiosis. The lone star tick carries ehrlichiosis, southern tick associated rash illness, tick bite-induced allergy, canine ehrlichiosis, tularemia, and rocky mountain spotted fever. The American dog tick carries tularemia, and rocky mountain spotted fever, and tick paralysis. Powassan virus and Borrelia miyamotoi have the potential to be transmitted by the larval stage. Southern Tick Associated Rash Illness (STARI); As per the CDC, the cause of STARI remains unknown. Tick Bite‐Induced Allergy (alpha‐gal allergy) is non‐pathogenic. Lone star ticks may carry a less virulent form of rocky mountain spotted fever. Tick paralysis is non‐pathogenic, and mostly associated with adult female American dog ticks. dontgettickedny.org nysipm.cornell.edu

Tick-borne disease is very common in the Northeast. In addition to Lyme disease, ticks in the northeast transmit the pathogens that cause Anaplasmosis, Babesiosis, Ehrlichiosis, Powassan Virus, Rocky Mountain Spotted Fever, Tularemia and a bacteria related to the agent of Lyme disease called Borrelia miyamotoi. But different ticks carry different disease pathogens.

In addition, not all life stages are equal. Most disease pathogens are ingested by the tick when they feed on an infected host. Adults are usually twice as likely to be carrying pathogens than a nymph because they have fed twice compared to the nymph’s single feeding. But we also know that Borrelia miyamotoi can be transmitted from an infected female to her eggs, so larval blacklegged ticks cannot be discounted as disease vectors.

School nurses can play a crucial role in tick education. This was covered in our guest blog, The Role of School Nurses in Integrated Pest Management for Public Health.

#JustWrongEnough 2: Ticks are found in tall grass.

The risk: Individuals will only think about tick prevention and conducting a tick check when visiting areas with tall grass.

Different tick species prefer different habitats, but that does not mean that you won’t find them in other areas as well.

We can find ticks in tall grass, but we are less likely to find blacklegged ticks. And species matter! The three New York ticks that pose the highest risk to us are the blacklegged tick, American dog tick, and lone star tick. These three ticks prefer different habitat types.

Blacklegged ticks prefer shady, moist areas. Dehydration is their greatest enemy, and so you are most likely to encounter them in the woods. But that doesn’t mean you won’t find them in a lawn or athletic field, especially in areas that receive significant shade. Ground covers, like pachysandra, found right next to buildings, can also provide suitable habitat for these ticks.

On your school grounds, students will likely have little risk of tick exposure in the middle of the playing field, but it’s a different story when they chase a ball into the wood edge.

How can you determine if there are tick risky locations on your school or child care grounds? You can use a simple drag cloth to monitor for ticks, covered in the blog, Ticks: Assessing the risk at schools and child care centers. This is also covered in our infographic, Monitor for Ticks in Your School Yard.

If you find locations with tick activity, you can take steps to restrict students from those areas by placing orange cones or signage. When access can’t be restricted, students and parents should be made aware of how to protect themselves from ticks.

#JustWrongEnough 3: Ticks are a summer problem.

The risk: Individuals will only think about tick prevention and conducting a tick check during hot weather.

American dog ticks and lone star ticks don’t mind the hot weather and can be a summer problem. But just as different species of ticks prefer different habitats, they also have different seasons when they are most active.

For the blacklegged tick, which is responsible for most of the tick-borne diseases in NY, the nymphs are most active in the spring and the adults most active in the fall. It is true that larvae hatch in the summer, and now that we know that they can transmit Borrelia miyamotoi we need to protect ourselves against them as well, but the greatest risk for disease transmission are in the spring and fall.

The different life stages of blacklegged ticks are most active in different seasons, but ticks that did not find a host will continue looking when the weather is favorable.

#JustWrongEnough 4: I can’t prevent ticks from getting on me.

The risk: Individuals are so afraid of ticks that they avoid spending time outside.

Here’s a gratuitous picture from a recent hike to highlight what you could be missing if you let a fear of ticks keep you inside.

We often find we are walking a fine line between frightening people and encouraging them to take precautions. Our underlying message is you can go outside. There are proven methods that can be used to protect ourselves from tick bites and the pathogens that may be transmitted while the tick is feeding.

Dressing the part, using repellents correctly, conducting daily tick checks, and knowing how to properly remove a tick can help you return from your next outing tick free. Details on these steps can be found on our How Do I Protect Myself From Ticks? page of our Don’t Get Ticked NY website.

So let them play outside during recess. Take your students outdoors. And schedule that field trip.

Slime Mold – Pest or Not?

Leave a reply
“A word is worth a thousand pictures, if it is the right word. Risk is the right word.” – Michael Hoff, PhD

When a problem presents itself, the first step should often be to determine whether it really is a problem. In other words, does it create a risk? At times, something may look scary, but may actually be eating other insects that are pests (house centipedes are a great example of this). Slime mold, a fungus-like organism, showing up in a school playground recently brought up the question of risk and how to react to it.

No one wants to walk out of their building and see this. Photo: Doug Beckers flickr

From the Plant Disease Diagnostic Clinic fact sheet:  “Slime molds are frequently observed when they form large colonies on mulch around trees or shrubs. They may initially appear as a slimy mound or mass, come in a variety of colors, and are often unsightly.”

Unsightly indeed. It is often called dog vomit mold.

So a school was very concerned when it started popping up throughout the playground mulch. They began making phone calls which led to us. We were able to reassure them that slime mold feeds only on bacteria in the mulch and there are no known health risks associated with them.

Slime mold crusts over after it finishes with its mobile stage. Still unattractive.

Human health risk usually reaches the highest tier of concern for risk assessment. Given the low risk, the school could just wait it out until the weather changes. Slime mold thrives under hot and humid conditions. Cool, dry weather would take care of the issue. It’s a good reminder that many pests (or, in this case, non-pests) are weather related and checking the forecast can help us determine how long the issue might last.

A change in the weather is sufficient to recreate the world and ourselves. – Marcel Proust

It’s worth noting that there are no pesticides registered in New York to manage slime mold on mulch. Any use of a pesticide would not only be illegal, but would also cause its own unnecessary risk.

There is another concern that falls lower down on the list, but is still important – perception of risk. In this case, there was a concern about how parents of young children would react to the unsightly mounds. To address this concern, we recommended shoveling out the visible slime mold and hosing down the area to disperse residual materials. And reminded them that as long as the weather remained hot and humid, slime mold would continue to pop up, so keep the shovel at hand.

A unrealistic perception of risk can also be addressed through education. So we found this nifty video about these fascinating organisms and how they move. Check out this Deep Look video from PBS. Talk about a teachable moment!

Managing traffic is IPM

Are you interested in turfgrass management? Especially as it relates to sports fields? Then the ShortCUTT (Cornell University Turfgrass Times) newsletter, written by Associate Professor and Extension Turfgrass Specialist, Dr. Frank Rossi, is for you! Check out a segment of this week’s offerings.

Frequently Asked Questions:

In the simplest of terms, the more use a field receives, the more preparation it will need prior to the initiation of use, maintenance during the traffic period, and recovery maintenance following the traffic. Photo: Bob Portmess

My fields are showing wear stress already after three weeks of use as a result of rainy and now very warm conditions. I’m trying to speak with coaches and parents about field use under these conditions. They keep asking the same question of me, “how many hours of use CAN the field handle”? Can you help?

First big kudos for recognizing the need to communicate with your clients regarding the conditions and safety of the fields. Effective communication is the consistent characteristic of successful professional sports turf managers. We have provided some useful tools to assist with the general information for players, parents, coaches and athletic directors at http://safesportsfields.cals.cornell.edu/coaches.

Additionally, there will not be any hard fast answer to the question without some qualification and understanding of the root zone, type of use, maintenance inputs, and visual quality expectations.

Our first responsibility is to ensure player safety as measured by field hardness, evenness and traction; other field issues become subjective as to what constitutes an “acceptable playing surface”. Again, there are gray areas when discussing amount of use, as poor weather experienced over the last 30 days has led to significantly more wear stress and field decline than expected under average weather patterns. Finally, larger amounts of managed field area that allows for dispersal of focused traffic and the availability of synthetic surfaces both significantly increase overall amount of natural grass playing field use.

Rootzones:

Soil properties impact traffic tolerance.

Loamy soil root zones with some drainage and some irrigation can withstand more than the average amount of use. Sand-based fields with excellent drainage can withstand significantly more than the average amount of use.

Type of Use:

Any type of field use that results in repetitive focused traffic, i.e., between the hash marks, goal mouths, sidelines, will reduce the amount of field use. Larger male athletes create more traffic stress than lighter female athletes. Youth sports with smaller athletes and smaller field dimensions that can be rotated, allow for much more use than average. Again rotation allows for dispersal of the traffic.

Schools and community parks are able to provide different levels of field maintenance based on their budget and the resources on hand that include labor (knowledge and experience), equipment and products. Other factors play into shifting resources, such as desired quality, type of field and use (practice vs game fields).

Maintenance Inputs:

Reasonable care of fields is expected as outlined in ASTM F2060 for cool season natural grass fields – this will include some amount of field rest and recovery as outlined in these important maintenance schedules. In the simplest of terms, the more use a field receives, the more preparation it will need prior to the initiation of use, maintenance during the traffic period, and recovery maintenance following the traffic. No maintenance program will compensate for overuse that leads to decline in field quality below acceptable levels and will need a routine turf replacement program as seen in most professional sporting venues.

Visual Quality Expectations:

A soft, bright green field with poor traction is less safe than a slightly brown, firm, even surface. Photo: Joellen Lampman

Players, coaches, parents and Athletic Directors have the right expect to safe playing fields. Sports turf managers must have field safety measurements to effectively determine when field use leads to decline in safety. The visual quality of the field often is correlated to field safety but not always, as a soft bright green field with poor traction is less safe than a slightly brown firm even surface.

In the end, general guidelines suggest good field conditions can be maintained with reasonable care at between 400-600 hours of use per year per field. Beyond 600 hours of use expect a loss in field quality and significant thinning and wear areas even under ideal conditions.

Bed bugs in schools aren’t going away

Leave a reply
“Coming together is a beginning. Keeping together is progress. Working together is success.” –Henry Ford

Bed bugs in schools are an issue that is not going to disappear. We have many resources available to help people deal with the issue, but, as is often the case, these resources are not looked for until there is a crisis.

Finding a bed bug in any situation can be distressing, but should not be a cause for panic.

This became clear, once again, as a distraught school official called to ensure that the pesticide application they were planning was legal. When asked if the pesticide applicator had found an infestation, the answer was “We know there isn’t one”. The strategy had been to spot treat when a bed bus is found. But the problem has escalated. Parents are pulling their kids from school. The union is involved. Finger pointing is rampant. The pesticide application was planned to show that SOMETHING is being done.

But we know that it isn’t going to help. Eliminate every bed bug in a building and the very next day a student or staff member can bring in another hitchhiker from an infested home.

So what is the solution?

Bed bugs are, simply, a community problem. It is nearly impossible to determine who is at fault and laying blame is pointless. The old saying states that it takes a village to raise a child. It also takes a village to deal with a bed bug problem.

First, know that it is nearly impossible to prevent bed bugs from entering any public facility. They will hitchhike on personal items from infested homes. These introductions are common in schools, office buildings, movie theaters, retail stores, libraries, taxis, buses, trains, diners,…

Bed bug infestations are rare in schools, but introductions from infested homes, usually on personal items that travel from home to school and back again, are quite common.

Second, infestations do not happen unless bed bugs have the opportunity to feed. They hate disturbance, prefer darkness when feeding, and need a body to be still, usually for two hours or more – not conditions typically found in schools.

Third, especially in apartment units, a family might be doing their best to control bedbugs, but a neighbor’s untreated apartment can lead to constant reinfestations. And there are multiple reasons for residents to not report bed bug infestations within their apartments, including:

  • Bed bugs might not have been noticed. Not everybody reacts to bites.
  • Residents are ashamed or embarrassed. Despite the fact that anyone can get bed bugs, there is the false stigma that bed bugs are associated with poverty and unsanitary conditions.
  • There is a risk of being charged for treatment or being evicted, even when the landlord is responsible.
  • Treatment is expensive and the resident might not have the resources to hire a pest management professional.

A national organization called eXtension has developed an IPM Action Plan for Bed Bugs that addresses the responsibilities of the school community and parents (and, in extreme cases, local government). Both lists include education. The NYS IPM Program can help with educational resources (below) and workshop opportunities.

The Action Plan goes on to discuss procedures that should be followed if a suspected bed bug is found and what to do if children repeatedly come in with bed bugs. It even provides recommendations for further intervention when children continue to come in with bed bugs despite interventions. A small sample of listed procedures include:

  • If a confirmed bed bug was found on a child then the school nurse should inform the child’s parents. [A letter and] inspection report should be sent home with the student. (See Bed Bugs: What Schools Need to Know fact sheet for a good sample letter). Educational materials should accompany the letter.
  • In most instances students should not be excluded from school due to bed bugs. Schools should not be closed due to the discovery of bed bugs unless there is a widespread infestation [which is rare].
  • In an infested home, parents should store their child’s freshly laundered clothing in sealed plastic bags until they are put on in the morning. This prevents bed bugs from hiding in the clothing and being carried to school.
  • Backpacks, lunchboxes and other items that travel back and forth to school can also be inspected daily and stored in sealed plastic containers at home to prevent bed bugs from getting into them. [Backpacks can also be treated in a hot dryer.]
  • At school a “hot box” might be used to heat treat belongings possibly infested. A hot box is an insulated container with a heating element that raises the temperature above 115 degrees, killing bedbugs. They can be purchased for a few hundred dollars. Dryers that contains shelves will also serve the same purpose.

Action plans can then be formatted as a flowchart, making decision making simple to understand and follow. The Michigan Bed Bug Working Group put together the Bed Bugs: What Schools Need to Know fact sheet with a sample flowchart.

This flowchart is part of Bed Bugs: What Schools Need to Know. The fact sheet also includes a sample parent letter.

We recommend that every school develop a bed bug policy based on the recommendations within the IPM Action Plan for Bed Bugs and use NYS IPM Program resources to help educate the school community and beyond regarding bed bugs and how to deal with them.

NYS IPM Bed Bug Resources

And be sure to check out a potential grant opportunity to help the school community purchase the airtight containers and heating units needed to help prevent bed bug transportation. The Walmart Foundation Community Grant Program offers grants ranging from a minimum of $250 to the maximum grant of $5,000. We do not know if they have ever funded this type of project, but let us know if you are successful!
