Do you have unwanted pesticides? Maine’s Obsolete Pesticide Collection Program offers a safe, free way for homeowners and family-owned farms to dispose of outdated or unused pesticides. One-day collection events will be held in Presque Isle, Bangor, Augusta, and Portland this November.

The program is a joint effort of the Maine Department of Agriculture, Conservation and Forestry’s Board of Pesticides Control (BPC) and the Maine Department of Environmental Protection. It is designed to protect public health and Maine’s natural resources by preventing improper pesticide disposal.

Why This Matters

Improper disposal of pesticides can pollute soil, groundwater, and surface water, posing risks to humans, pets, livestock, and wildlife. Since 1982, Maine’s Obsolete Pesticide Collection Program has safely diverted more than 250,000 pounds of hazardous pesticides from the waste stream.

Collected materials are transported by a licensed hazardous waste contractor to specialized, out-of-state disposal facilities that meet strict environmental safety standards.

“This program provides safe and environmentally responsible disposal of unwanted pesticides for homeowners and family-owned farms,” said Karla Boyd, BPC Policy & Regulations Specialist. "By participating, people are directly protecting our land and water for future generations.”
