Thank you to guest blogger Paul D. Curtis, Department of Natural Resources and the Environment, Cornell University.

 

Woodchucks (Marmota monax) are large members of the squirrel family and are closely related to other species of marmots in North America. They usually are grizzled grayish brown from head to toe. Their compact, chunky body is supported by short strong legs. The forefeet have long, curved claws that are well adapted for digging burrows.

Like other rodents, woodchucks have chisel‐like incisor teeth. Their eyes, ears, and nose are located toward the top of the head, allowing the animal to remain concealed in its burrow while checking for danger over the rim of the burrow opening.

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 – 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.

Pesticide Use Guidance During COVID-19

Our friends over at Cornell’s Pesticide Management Education Program (psep.cce.cornell.edu) has asked us to help spread information on disinfectants and sanitizers. During the COVID-19 pandemic, there has been an increase in adverse health effects from the misuse of these products. There have also been several fraudulent products produced during this time that potential applicators should be made aware of. Please read and share the following:

Beware of fraudulent pesticide claims related to SARS-CoV-2 (the COVID-19 coronavirus):

It has come to our attention that unregistered disinfectants claiming to protect against the virus are being marketed in the US. The efficacy and safety of these products is unsubstantiated and their use is illegal.

Regulators are taking steps to prevent such products from reaching the market, but it is your responsibility to use only those products designated by the New York State Department of Environmental Conservation for use against SARS-CoV-2, listed at https://www.dec.ny.gov/docs/materials_minerals_pdf/covid19.pdf. Please check this list frequently, as content is subject to change.

Be safe disinfecting your home:

Disinfectants are pesticides and you can only use them as directed by the label. Therefore:

  • Never mix different disinfectant products together because doing so is dangerous. For example, mixing bleach with acids (such as vinegar) or ammonia releases life-threatening toxic fumes.
  • Never use disinfectants or disinfectant wipes on your skin. Instead, wash with soap and water; you can also use hand sanitizer on your hands.
  • Never wash fruits and vegetables with soap, sanitizers, or disinfectants as this could also result in poisoning. Wash produce only in clean water.
