Our friends over at Cornell’s Pesticide Management Education Program (psep.cce.cornell.edu) have 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.

Commercially available “tick tubes” are tubes filled with permethrin-infused cotton. Mice take the cotton to line their nests and are treated for ticks every time they return home. It’s estimated that a typical ¼ acre yard needs six tubes twice a year, with a 12 pack costing ~$45 . Although this cost isn’t excessive, there are many videos and articles on making DIY tick tubes to help people save money. But what is the actual cost?
A dozen tubes covers about a 1/4 acre for $45. (Image does not imply endorsement.)
3 Reasons Why Making Your Own Tick Tubes is a Bad Idea:
1) They 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. The formulation used in commercially available tick tubes is uniquely suited for controlling ticks on mice. Other permethrin formulations are designed for other uses which are specifically listed on the label.
2) You could be putting yourself, others, pets, nontarget animals, and the environment at unacceptable risk.
Tick tubes target ticks attached to field mice. When spending time in the nest, mice expose themselves to the tick-killing products.
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 making your own tick tubes is NOT a use listed on the label of any permethrin product. One potential risk: Permethrin is highly toxic to bees. Bumble bees often nest in abandoned mouse burrows, so making your own tick tubes could harm these important wild pollinators.
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 tick tubes 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, pollinators, and the environment at risk. DIY tick tubes that pose greater risks while providing poorer control of ticks are hardly a bargain; be sure to use the real thing.

New York, like the rest of the world, is highly dependent on the hundreds of species of crop pollinators that collectively contribute roughly $170 billion a year to the global economy. Many are in decline and under threat in New York and elsewhere.
That’s why Dean Kathryn J. Boor ’80 recognized the Cornell Pollinator Health Team for their outstanding outreach accomplishments in a ceremony that celebrated research, extension and staff excellence.
On hand to accept from Dean Kathryn Boor (L) were (L-R) Jennifer Grant, Bryan Danforth, Dan Wixted and Scott McArt.
The seven-member team includes entomologists, extension outreach specialists and pest management experts — one being NYS IPM‘s director Jennifer Grant.
The team provides critical extension and outreach on pollinator declines, including information on
optimal habitats for honey bees, native bees, and other pollinators
diseases that afflict bees
how pesticides affect bees — other pollinators too
what to do when your honey bees are in decline

With its focus on extension and outreach, the team has given more than 70 extension talks over the past three years in New York and elsewhere on pollinator health, bee diversity, integrated pest management practices and pesticide recommendations that minimize risks to bees — to all pollinators, in fact. Their audiences have included beekeepers, farmers, and lawmakers — as well as state and national organizations such as the New York Farm Bureau, the Audubon Society and Future Farmers of America.
“In three short years, the work of this team has made a notable impact both in scope and relevance to beekeepers,” Boor said at the ceremony. “The pollinator health team represents a model for how collaboration among different units at Cornell can lead to highly integrative and creative extension and outreach.”

by Matt Frye Comments Off on Understanding Over-the-Counter Sprays for Mosquitoes and Ticks
Summer is the season that brings us outdoors to enjoy picnics, barbecues and campfires. Unfortunately, blood-feeding arthropods such as mosquitoes and ticks can ruin our outdoor experiences by making us itch or by spreading disease. Over-the-counter sprays are one way that people avoid a forced retreat to the indoors. Choosing the right product and understanding how it works is important to keep you and your family safe. Here are a few considerations.
Repellant vs. Pesticide. There are two classes of products that you might see on the shelf. Products that contain DEET, picaridin, oil of lemon eucalyptus and IR3535 are repellants. These products interfere with the host-finding abilities of biting insects, making you hard to find. On the other hand, products that contain permethrin are pesticides that kill these organisms on contact. Permethrin is used to treat clothing, hats, shoes, and gear (backpacks, tents, etc.), and should never be applied to the skin for safety reasons.
Repellant Formulation. Repellants differ in their effectiveness at keeping pests away. On the bottle is a “percent active ingredient” listing, which is a measure of how long the product will remain effective. The higher the percentages, the longer it lasts. In general, products with less than 10% active ingredient provide only limited protection (1-2 hours at most). Here are some specifics about two of the common active ingredients.
DEET comes in concentrations from 4 to 100%. Despite this broad range, studies have shown that concentrations over 50% do not provide any additional protection. Therefore, products with 20 to 30% DEET are recommended for outdoor exposure of four to five hours.
Picaridin concentrations range from 7 to 20%, with a 20% concentration providing four to five hours of protection (equivalent to DEET at the same concentration).
How to Apply. For repellents, use just enough product to cover exposed skin and clothing – do not over-apply. Never directly spray your face, but rather spray your hands and apply to areas as needed. Follow label instructions carefully for applications, especially for children.
Treatments using permethrin to protect clothing should be done outdoors in an area with limited wind. Treat materials according to the label, paying particular attention to the amount of time needed for the product to dry. In most cases, once the material is dry, it is safe to wear. Additional information can be found on the TickEncounter website, including information about having your clothing professionally treated.
Clean Up. After outdoor exposure, a shower is recommended to remove repellants applied to skin. This should be followed by a tick check. See TickEncounter’s Shower Cards for more information.
Other Options. Screenhouses and appropriate clothing, such a long pants, long-sleeved shirts and a hat can be utilized to reduce problems with biting insects. Visit the following links for information on managing mosquitoes and ticks in your yard.

by Joellen Lampman Comments Off on Child Safe Playing Fields Act – Frequently Asked Questions
A New York law essentially banning pesticide use on the grounds of schools and day care centers has been full effect since 2011. The letter of the law states:
No school or day care shall apply pesticide to any playgrounds, turf, athletic or playing fields, except that an emergency application of a pesticide may be made as determined by the county health department or for a county not having a health department such authority as the county legislature shall designate, the commissioner of health or his or her designee, the commissioner of environmental conservation or his or her designee, or, in the case of a public school, the school board.
Questions about the law still abound. Here are the most common questions we receive:
What areas are affected?
The inside of this child care center’s fenceline falls under the Child Safe Playing Fields Act.
Besides the playgrounds, turf, athletic or playing fields clearly stated in the law, playground equipment and fence lines around athletic fields and tennis courts are included.
The following areas are left to local discretion, but with the understanding that the intent of the law is to reduce children’s exposure to pesticides:
Areas around buildings
Ornamental plants such as trees, shrubs, and flowers
Pesticides used inside of schools or day care centers, or to protect a structure, are not banned.
Family day care centers are exempted.
What if a fence line is managed by the surrounding landowner (such as childcare center on a college campus)?
The law applies to the interior fence line that encloses the play area (the side that children may contact). The law would not apply to the exterior fence line.
If a park hosts school athletic events, such as games and practices, must it be managed under the law?
What pesticides are banned and are there any exceptions?
Pesticides are substances intended to prevent, destroy, repel, or mitigate pests. They include insecticides, fungicides, herbicides, rodenticides, and plant growth regulators. All EPA registered pesticides are banned by this law for use on grounds at schools and day care centers, with the following exceptions:
Antimicrobials such as bleach
Aerosol sprays (18 ounce or less) to protect from imminent danger from stinging or biting insects
Insect and rodent baits in non-volatile containers
Products containing boric acid or disodium octaborate tetrahydrate
Note that all of the above exceptions (except bleach) must be applied by a NYS licensed pesticide applicator. Any off label use of a product – such as the use of bleach, road salt, or home remedies to control a pest – is illegal under state law.
Is there a provision within the law to add additional materials to the exempt list?
No. A change would require either the EPA to add to its 25B list or the NYS legislature to pass new legislation.
While clover does not provide the traction and stability of turfgrass, it is considered a repetitive pest problem and not an emergency under the law.
Can you tell me more about these emergency exemptions?
Under the law, a public school can seek permission for an emergency application from their school board. Non-public schools and day care centers ask the Department of Health in the case of emergencies that threaten public health, such as ticks, or the DEC for those significantly affecting the environment, such as an invasive species.
While the law does not indicate what might be construed as an “emergency”, the Guidance document states pest issues are NOT emergencies if they are:
manageable with allowed products and practices
a routine or repetitive pest problem
purely an aesthetic issue
We are used to dealing with the DEC on pesticide issues. Besides deciding on emergency exemptions for environmental issues on private school and day care grounds, what is their role in the law?
The Department of Environmental Conservation, in consultation with the State Department of Education, State Department of Health, and the Office of Children and Family Services has written guidance for alternative management of turf, but has no role in enforcement.
Where can I find help in managing my grounds without the use of pesticides?
