Ticks and Schoolyard Edges

The time of the falling leaves has come again. Once more in our morning walk we tread upon carpets of gold and crimson, of brown and bronze, woven by the winds or the rains out of these delicate textures while we slept. – John Burroughs, The Falling Leaves

Leaf blowing leaves is a common practice, but does it cause a risk for more ticks?

A recent study, Artificial Accumulation of Leaf Litter in Forest Edges on Residential Properties via Leaf Blowing Is Associated with Increased Numbers of Host-Seeking Ixodes scapularis Nymphs published in the Journal of Medical Entomology, showed that areas where leaves were raked or blown into forest margins tripled the number of blacklegged tick nymphs compared to areas where leaves were not artificially accumulated. (There was no observed impact on lone star ticks.)

Most ticks were found along the woodland edge.

Combine this with the findings of a Cornell study, Active surveillance of pathogens from ticks collected in New York State suburban parks and schoolyards, and it is clear that woodland edges are the areas of highest risk for students to encounter ticks. Fortunately, most students don’t spend much time in these areas. Unfortunately, students will chase stray balls into these areas when ticks are furthest from their minds.

What can you do to protect students from these tick risky areas? Step one would be to monitor your school grounds for ticks. This low tech monitoring technique can easily be accomplished by a coach, playground monitor, or even students. Knowing that ticks are active can allow for some adjustment of play, like putting up cones to let students know areas are off limits.

Is there an area with consistently high tick activity? Installing fences or netting can prevent stray balls from entering wooded edges. Think of it as reverse exclusion – in this case, we’re keeping the students out of the pest areas.

Keep in mind that blacklegged ticks prefer high humidity, so look to reduce shady and damp areas where students spend time. We can modify parts of the school grounds to make them less hospitable to ticks by:

  • Removing leaf litter from wooded edges in high traffic areas
  • Removing trees shading play areas if monitoring shows those areas have tick activity
  • Replacing wood mulch, which can store moisture, if monitoring shows tick activity,  with a different, drier option
  • Widening trails to reduce the risk of students brushing against vegetation
  • Eradicating invasive plants, such as Japanese barberry, honeysuckle, and multiflora rose, that easily establish along wooded edges, and have been associated with higher concentrations of ticks carrying disease-causing pathogens

School IPM 2020 Conference

When it comes to student learning and achievement, the physical environment is a full partner.” – Dr. Lorraine Maxwell, Cornell University A picture of a school with a banner that says "School is Open Humans Only" with a bedbug, cockroach, tick looking at the sign.

Another annual NYSIPM Conference is in the books and it was certainly different from what we imagined when we started planning last year. Covid-19 caused us to move the in-person gathering from April to a virtual conference in August. (Silver lining: it turns out virtual conferences are easier to get online than those we record with a video camera. You can now view the conference presentations from our YouTube channel.)  The virus also both supported and distracted from our main goal of discussing school pest issues that need community interventions to address.

As I discussed in my July post, Back to School – Humans Only!, Covid-19 is an excellent example of an issue that cannot be handled by school personnel alone. We have all been called to support the openings of schools through practicing social distancing, wearing masks, and handwashing whenever we leave our homes. As we looked at pest issues with similar community connections, examples included pests like bed bugs coming into schools on backpacks, but also wheelchairs and cockroaches coming in supplies and food packaging. Increasing communication and engaging collaborators that can help address these issues in the community preventing the introduction of pests into schools were brought up repeatedly. You can view that discussion here. Drs. Dina Fonseca and Paul Curtis also provided us with excellent examples of community members working together to manage mosquitoes and deer.

Besides influencing our conference, how else will Covid-19 impact schools from an IPM perspective? A few virus mitigation practices have direct impact on pests.

Reduced clutter

Photo of slide from conference: "Summary – NYC study Students’ perception of the school’s social learning environment is, in part, shaped by the physical quality of the school building. The social learning environment affects student attendance and subsequently academic achievement. Demographic factors play a role but school building quality remains an important contributing factor to the learning environment."

School building conditions matter in learning outcomes.

To decrease items that need to be regularly cleaned and sanitized, only required items are being kept in classrooms. The elimination of furniture and cushions, fewer books, less arts and crafts materials (or materials stored in easy to clean containers) will provide less space for pests to hide. We touched on this in the blog post, Bed Bugs in Schools – Prevention. And, as we learned in our keynote address, Healthy Environments for Learning by Dr. Lorraine Maxwell,  too much clutter can also lead to cognitive fatigue. While there is much influencing learning outcomes this year, we can hope that simplifying classrooms will help reduce pests and support learning.

Food in the classroom

There will be expanded food in classrooms as student travel within building is curtailed. Breakfast in the classroom has already proven to be challenging. This year lunch in the classroom, as well as teacher breaks, will increase the volume of food and food waste, the number of spills, and the amount of cleaning occurring throughout the school. On the School IPM Best Practices website, you can find information and resources on breakfast in the classroom.

Ventilation

To increase ventilation, windows and doors are being encouraged to be left open. Open doors leave opportunities for rodents and flying insects to enter buildings. Windows should have screens in place to exclude pests, but have screens been checked for holes or bent frames? Bobby Corrigan discussed rodent exclusion in his presentation, Identifying and Understanding the Rodent Vulnerable Areas (RVAs) of Schools: Essential for Sustainable IPM.

Sanitation

With IPM, we usually discuss cleaning more than sanitation, but Covid-19 has created a shift. (Note: this is unfortunate as this particular virus succumbs to soap and water.) We are not the experts on this issue, but have included a couple of blog posts to help provide some guidance:

The most important outcome of the conference is the message that school building matters and, indeed, as Dr. Maxwell concludes, “When it comes to student learning and achievement, the physical environment is a full partner.” And we all have a part to play.

Back to School – Keeping the Rodents Outside

We should have little trouble with vermin if builders would hear and understand the ‘language’ of vermin and do a better job in eliminating their entrances and hiding place.” – Hugo Hartnak, 1939

For Bobby Corrigan, pest management is a passion. Called upon for his expertise across the country, we are honored to include him in our conference.

Pests enter school buildings in one of two ways: they are transported in by students, staff, or delivery truck or they make their way in from the outside. The School IPM 2020: Where We’ve Been and What’s Next virtual conference will focus on the first mode, but we will also include information on the second with tips, and a tool, to help with exclusion – or keeping pests out of buildings. Dr. Bobby Corrigan, co-founder of the first Scientific Coalition on Pest Exclusion, will join us to discuss rodent vulnerable areas.

All conference participants that complete the pre- and post-tests and evaluation will be mailed a Frye Inspection Tool (FIT tool). This simple probe can be used to demonstrate if a rodent can squeeze under a gap or through a round opening. By design, if the probe ‘FITs,’ so too can the specified rodent. This tool can be used to educate decision makers about rodent entry points and help justify pest exclusion.

A F.I.T. tool allows you to assess potential rodent entryways and identify whether gnaw marks and droppings were caused by rats or mice.

The measurement specs for the FIT are based on the size of adult rodent skulls. If a rodent can fit its head under a gap or through an opening, they are able to wiggle their body through (watch video Mouse Entry Points to see a mouse in action). The FIT can also be used to help differentiate rodent evidence (both gnaw marks and droppings) between rats and mice.

Signing up as a school district? We will mail enough FIT tools to cover all the participants from your district, so be sure to provide information for them all.A picture of a school with a banner that says "School is Open Humans Only" with a bedbug, cockroach, tick looking at the sign.

Back to School – Humans Only!

A picture of a school with a banner that says "School is Open Humans Only" with a bedbug, cockroach, tick looking at the sign. The tick is holding a mouse pull toy and the cockroach is holding a coronavirus shaped balloon.Schools across the world are having conversations about safely sending teachers, students, and the rest of the school staff back for face-to-face education during a global pandemic. These are vitally important discussions and plans need to adapt to new information. And this focus on school health and safety also provides an ideal, if unanticipated, backdrop for our rescheduled annual conference – School IPM 2020: Where We’ve Been and What’s Next.

Covid-19 is an excellent example of a community issue that cannot be handled by school personnel alone. We have all been called to support the health of the community through social distancing, wearing masks, and handwashing. Our conference will focus on community-wide pest issues such as German cockroaches and bedbugs. There is simply no way for schools to prevent these insects from being reintroduced by students, school staff, and delivery trucks. How then, as a community, can we address these issues before they breach the school walls? And avoid the subsequent calls by some to close the building for pesticide applications?

The penultimate hitchhiker, bed bugs need to be dealt with at a community level.

Please join us on the mornings of August 11 and 18 as we hear from community and agency leaders – and you! – about efforts to provide healthy learning and work environments. We welcome your experiences and ideas as we use this momentum to address school pest issues now and into the future.

Managing Wild Parsnip

“As everyone knows, when fighting a zombie, you grab a shovel and aim for its head. The same with wild parsnip, except you aim for its feet.” – Paul Hetzler

The bright yellow flowers of wild parsnip can be noticeable from a distance. The sap in this widely spreading invasive plant can cause severe burns.

There is no lack of invasive species in New York – but some do raise more of a concern than others. One such is the wild parsnip. Commonly spotted along roadsides with its bright yellow flowers, it can cause a problem on low maintenance areas on school grounds.

According to the New York Invasive Species Information Clearinghouse, wild parsnip produces furanocoumarin, “a compound in its leaves, stems, flowers, and fruits, that causes intense, localized burning, rash, severe blistering, and discoloration on contact with the skin on sunny days”. Avoid the sap and avoid the chemical burns.

In order to avoid those burns, the NYS DEC recommends:

  • Do not touch any parts of the plant with bare skin.
  • Wear gloves, long-sleeved shirts, pants, boots and eye protection if working near wild parsnip to prevent skin contact with the sap. Synthetic, water-resistant materials are recommended.
  • If contact with sap occurs, wash the affected area thoroughly with soap and water, and keep it covered for at least 48 hours to prevent a reaction.
  • If a reaction occurs, keep the affected area out of sunlight to prevent further burning or discoloration, and see a physician.

Digging out the root, cutting the root an inch or two below the soil, mowing, and herbicides can all be effective in managing wild parsnip. It is unlikely, however, that an emergency exemption for herbicide use would be approved before seed drop. Mechanical methods will have more long-term benefits.

And wild parsnip is going to seed, so make sure you don’t ensure a new crop next year by spreading seeds around! Before conducting any management, carefully cut the seed heads off with clippers and put them in a plastic bag. The bag can then be left in the sun to rot the seeds before disposal. And don’t forget to wear protective clothing to prevent any sap from reaching exposed skin or eyes.

If you want to learn more about wild parsnip and its management, our favorite guest blogger Paul Hetzler covered it well and humorously in his blog, Vengeful Veggies.

For more pictures of wild parsnip, visit the Turfgrass and Landscape Weed ID website. For information on other  invasive species, visit the New York State IPM Program’s Invasive Species page.

And, just in case we didn’t quite get the message across – wear protective clothing and eye wear to prevent sap from causing severe burns.
