Today, we want to emphasize ways to EXCLUDE pests. Exclusion is a fundamental way to reduce pests in buildings. Unfortunately, it’s not always a quick and easy job.
Some gaps are easy to see. Improperly fitting door sweeps or gaps along utility lines, for instance. Others, like gaps along roof lines are harder to locate, and harder to access.
We’ve included some videos and some links to METHODS and exclusion product resources. NOW is a great time to address pest reduction or prevention needs in quiet school buildings. Trade names used herein are for convenience only; no endorsement of products is intended, nor is criticism of unnamed products implied.

While pests like bedbugs are inactive waiting out school re-openings, the old standards like cockroaches and rodents can use quiet buildings to their advantage if habitat needs are met. Food, water and shelter are available in areas such as storage rooms, kitchens, boiler rooms and crawlspaces. If your building is currently unoccupied, pest activity can go unnoticed by staff, especially if there is a disruption in pest control operator visits.
OUR NUMBER ONE SUGGESTION NOW IS…SCOUTING. Building maintenance remains (at this time) essential work. Just like in the summer months, buildings without students allow much great opportunity for extensive scouting and cleaning.
LOOK FOR PESTS, PEST ACTIVITY and PEST ENTRY POINTS. The partial inspection list below notes areas that may not be addressed daily during the school year. Now is the time to move large pieces of kitchen equipment in buildings no longer providing meals.

Weeding tools have come a long way! Last summer, Eric Gallandt invited me to present the results of my latest “stacked” cultivation trials at the Northeast Mechanical Weed Control Expo. I brought my camera along to document the exciting exhibits by vendors and other researchers. Stacked cultivation featured prominently, as did enhanced accuracy – achieved through improved steering capability or camera-guided tools.
(Above) KULT Kress demonstrated their camera guided sweeps and finger weeders (only one row operating). These weeds were too large for optimal finger weeder performance. In-row weeds are most effectively controlled when less than one inch tall.

by Debra E. Marvin Comments Off on Pests Take Advantage of Quiet School Buildings
THIS IS A REPOST OF a JUNE 2015 SCHOOL IPM Blog post by Joellen Lampman. The timing is significant. Closed school buildings are the perfect time to tackled sanitation and exclusion efforts that are hard to manage with students in the building. If your school cafeteria is providing meals (thank you!), we’ll also be posting about exclusion in other parts of the building.
“Cleanliness is not next to godliness. It isn’t even in the same neighborhood. No one has ever gotten a religious experience out of removing burned-on cheese from the grill of the toaster oven.” – ― Erma Bombeck
Move equipment to make it easier to clean the floor and walls around it as well as the equipment itself.
While cleanliness might not help you spiritually, we can promise that it will help you prevent pest problems in the school. There are certain tasks that should be done every day, some that can be done weekly, or even monthly, and some that should be done at least once a year. Schools vacated for the summer provide an excellent time to tackle the big jobs.
The primary idea is to remove pest habitat (food, water, shelter, and space) from buildings. This includes sealing off food, repairing water leaks, and removing shelter. Reach into the corners. Get under the sinks. Tackle molding, walls, and flooring behind and under appliances and cooking equipment. This is the time to pull out equipment and vending machines. Clean the wheels and wheel wells on carts and garbage cans. If resources allow, take the opportunity to put shelving on casters. This will make deep cleaning easier, and thus allow it to be conducted more often once school starts up again.
We can’t always blame the teachers and students. This cluttered custodial closet provides pest harborage and makes inspection and cleaning difficult.
What other pest projects are good for the summer? Ideally your regular inspections have helped you to produce a list of tasks to tackle. Many of these projects likely include projects that will help exclude pests from your building. They include:
Sealing gaps where utility lines (water pipes, electricity) enter the building and between rooms
Sealing all cracks and gaps in foundations, windows, door jambs and vents
Repairing holes or tears in window screens
Transplanting (or removing) plant material away from the building foundation
Replacing mulch next to buildings with gravel
Eliminating water sources such as leaking pipes, clogged drains, and missing tile grout
Insulating pipes that accumulate condensation (sweat)
Reducing clutter, cardboard, and paper that provides covers for pests
Seal pipe chases entering buildings, between rooms, and under sinks with foam and copper mesh.

“Frugality, I’ve learned, has its own cost, one that sometimes lasts forever.” – Nicholas Sparks
The label is the law and will tell you everything you need to know about using a pesticide correctly and legally. (Image does not imply endorsement.)
Some pesticides containing permethrin can be applied to clothing, footwear and gear to protect against mosquitoes, ticks, and other biting insects. Recent research confirmed that permethrin interferes with blacklegged, American dog, lone star and Asian longhorned ticks’ ability to move and, thus, to bite. EPA-registered products specifically designed for clothing contain 0.5% permethrin. A 22.5 oz. spray bottle claims to treat five outfits and costs $14. However, some people look to save money by buying a permethrin product meant for turfgrass or ornamental applications and diluting it to 0.5%. But what is the actual cost?
3 Reasons Why Making Your Own Permethrin Spray is a Bad Idea:
1) It probably won’t work. A pesticide product contains inert ingredients that help the active ingredient (in this case, permethrin) perform properly for the uses listed on the product label. Products used in clothing and gear sprays are uniquely suited for binding the permethrin to fabric and product labels tell you how long they will be effective (e.g., six weeks or six washes, whichever comes first). If you make a DIY spray with a permethrin product designed for other uses, it won’t bind as well to your clothes; thus, there is no way to know if it will work or for how long, putting you at risk for a tick bite.
2) You could be putting yourself, others, pets, non-target animals, and the environment at unacceptable risk. Permethrin can be harmful if absorbed through the skin and if a product is not designed to bind the permethrin to your clothing, the insecticide will instead move from the clothing onto your skin. For your protection, the EPA will register the use of a pesticide only if rigorous safety testing shows it will “pose no unreasonable risks to people or the environment when used according to label directions.” Only those uses listed on a pesticide label have met this standard, and treating clothing and gear is NOT a use listed on the label of other permethrin products.
3) It is against the law. Because of Reason #2, the first sentence in the Directions for Use section of all permethrin products is “It is a violation of federal law to use this product in a manner inconsistent with its labeling.” Which, by the way, also means it is against your state’s laws.
Commercially available permethrin clothing and gear sprays cost more because it takes time and money to develop the right mix of ingredients and conduct the required safety testing to ensure that the product will control ticks without putting people and the environment at risk. DIY treatments that pose greater risks while providing poorer control of ticks are hardly a bargain; be sure to use the real thing and follow all label directions.
“In the spring, at the end of the day, you should smell like dirt.” – Margaret Atwood
The spring of 2020 might have everyone’s yards incredibly tidy, as gardening and yard work are on the short list for things we can all do while social distancing. But COVID-19 isn’t the only disease we need to watch for, and new research shows that protecting yourself from tick-borne pathogens is more important than ever.
They’re active now
This table shows the textbook description of when blacklegged tick lifestages are active.
Blacklegged ticks are most active in the spring and fall, although you can often find them active year round if conditions are right (above 37o in the winter, cool and damp in the summer). Many still consider ticks to be a summer pest, but the poppy-seed sized nymph starts questing in the spring, and there have already been reports of nymphal activity in New York. These ticks are considered to be the most dangerous life stage due to their small size, so be sure to put all your tick prevention strategies into place now.
In reality, different blacklegged lifestages can be active almost anytime of year depending on weather conditions.
Keep it clean
A study looking at the effectiveness of recommended yard management measures against ticks showed the presence of trash could predict an increase in ticks over a clean yard, likely due to an increase in the number of small rodents that find both shelter and food amongst the trash. This was more pronounced in yards without forested areas. Sanitation is an important IPM step, so pick up and pack out that trash!
Check your leaves
Both adult and nymphal blacklegged ticks are active in the spring.
Identify areas in your yard where leaves have accumulated. Are they close to areas you spend a lot of time, like the kids’ swing set or your garden? It’s best to remove them. Are they in the far corner where no one ever goes? You can probably leave them, but be aware that the tick risk will likely be higher. Check for yourself. It’s pretty easy to monitor for ticks.
Back in 2013, the Northeast School IPM Working Group (NESIWG) received a Partnership Grant from the Northeastern IPM Center to develop a Best Management Practices (BMP) website.
Reducing pest and pesticide exposure is important for children, just as it is for district staff and visitors. But schools are especially challenging to manage because they include such varied and heavily used settings such as classrooms, cafeterias, laboratories, auditoriums, theaters, playing fields, playgrounds and gardens.

With the help of many contributors, the NESIWG both created and collected resources for school IPM. We wanted to help administrators, school boards, parents, teaching and support staff, athletic directors, groundskeepers, kitchen staff and custodians how a designated pest management plan can reduce both pests and the need for pesticides. The website was a success.
By 2018, NESIWG members saw the need to update old links and fill out gaps in the content. Eager to keep the website a useful and comprehensive resource, the working group applied for and received a NEIPM Communications grant. Again using focus groups, the following changes were made:
a reorganization of the pest species list,
additional information on relevant pesticide use regulations in all Northeastern states,
grouping resources by stakeholder roles,
the addition of two new pages: Breakfast in the Classroom and Playgrounds
Additionally, the recent grant included an update of the working group’s homepage, a new ranking of regional school IPM priorities, a current membership list and an index of school IPM contacts in the Northeast.

Soybean Disease Identification, Expansion of Soilborne Soybean Diseases and the Soybean Cyst Nematode in NYS, and Considerations for Soybean Seed Treatment Options for these Threats
Cayuga County CCE specialist Ron Kuck held a shop meeting at Dumond’s farm in Union Springs on February 19th. Jaime Cummings, Field Crops and Livestock IPM Coordinator at NYSIPM shared information on how to correctly identify, differentiate and manage soybean diseases, which seed treatments are most beneficial and cost-effective for soybeans in NY, and how to deal with the new soybean cyst nematode now that it’s been confirmed more widely in NY.
A good turnout on February 19 for a Cayuga County Shop Meeting. Growers concerned with soybean diseases heard the latest from NYSIPM’s Jaime Cummings.
Participants took a pre-workshop quiz to gauge their knowledge of the subject, and a post-workshop quiz to see how much they learned. And, they learned a lot! The average quiz rating before the workshop was 57%, and was 87% after. This means a 30% knowledge gain regarding when and which management methods are most effective for each soybean disease, including when pesticides are not the best option, and how to incorporate integrated pest management options for minimizing losses to the soybean cyst nematode.
Soybean Sudden Death (SDS) Foliar Symptoms
Ron Kuck received positive feedback from a number of participants, who each said that they appreciated the workshop and Jaime’s expertise and enthusiasm on the subject matter.
About 35 farmers and agriculture professionals attended February’s Shop Meeting in Union Springs, NY.

“When it comes to student learning and achievement, the physical environment is a full partner.” – Dr. Lorraine Maxwell, Cornell University
Despite decades of promoting school integrated pest management (IPM), bed bugs, cockroaches, lice, and mice continue to be a problem in schools. Part of the issue is lack of implementation of proven IPM techniques such as exclusion. Part of the issue is that some pests, like bed bugs, German cockroaches and lice arrive in backpacks, delivered supplies, and directly on students and staff. While schools often have plans in place to address these pests when they are discovered, it will take a wider community effort to prevent their introductions.
The Sixth Annual NYS IPM conference brings together a wide range of speakers to address and discuss the status of school IPM adoption and where we need to go in the future. If you or your family is impacted by pests or pest management on and off school property, this is the conference for you.
Our keynote speaker, Lorraine Maxwell, will discuss “Healthy Environments for Learning”. Her research has found that school building conditions, which include conducive conditions for pests as well as the presence of pests, impact the school’s social climate, which directly impacts student performance.
Using several different cultivation implements at once, or “stacking” tools, can improve weed control effectiveness. From my work at the University of Maine, Eric Gallandt and I showed that certain cultivation tools work synergistically together, particularly those combinations that undercut, then uproot, then bury weeds. Unfortunately crop damage was high in the trial results from Maine. So in New York, I made some adjustments to be gentler on the crop – wider spacing between tools, removed center tines on the row harrow, and tested a new hiller to bury weeds without contacting the crop (Figure 1). And GPS guidance was a big improvement too!
Figure 1. Cultivation implements used in these trials were A) sweeps, B) finger weeders (yellow and row harrow (blue), and C) a disk hiller. For full explanation of implement adjustments and trial methods, see the project report at https://ecommons.cornell.edu/handle/1813/64539
Figure 2. Results of cultivation trials in snap beans. This was the first cultivation event following planting and tillage. At cultivation, snap beans were 6” tall, while weeds were 0.5” tall in 2018 and 1” tall in 2019.
Figure 3. Results of cultivation trials in beets. First cultivation occurred at either the 2-leaf stage or about one week later at the 4-leaf stage. 2019 beets trials were planted in the spring, whereas 2018 beets were planted late-summer, with lower-growing winter annual weeds present.
Overall, the adjustments made in these trials greatly reduced crop damage while weed control remained high. I was most impressed with the stacked combo of sweeps plus fingers plus disk hillers, which consistently controlled the greatest percentage of weeds. These results also demonstrate that in-row cultivation should not be conducted prior to the 4-leaf stage in beets.
