DATCP invites homeowners and renters to sign up for 2026 growing season notices in the landscape pesticide registry. They can do this from November 1, 2025 through February 1, 2026.
Registrants receive advance notice from commercial lawn care companies that apply pesticides to lawns, trees, and shrubs on nearby property. Members of the public can submit addresses that they want to receive notifications for that are located on their block or adjacent blocks. There is no cost to register. Those wishing to be notified of pesticide application must re-register every year. To register online or to submit a paper application by mail, visit https://datcp.wi.gov/Pages/Programs_Services/LandPestReg.aspx.
The landscape pesticide registry will start March 15, 2026, when pesticide applicators are required to notify registrants at least 12 hours in advance of treating nearby properties with pesticides. The registry applies only to commercial landscape applications. The registry does not apply to:
- Homeowners or landlords who do their own pesticide applications
- Pesticide applications to the inside or outside of buildings; including around a workplace, school, or daycare center
- Pesticide use in agriculture
“Pesticide” is a broad term that can include herbicides, fungicides, and insecticides. To learn more about the landscape pesticide registry, visit datcp.wi.gov. The registry is a service offered by DATCP. For the 2025 growing season, approximately 3,900 addresses were registered to receive notice.
