Using the Montana Pesticide Waste Disposal Program in 2025

Cecil Tharp, MSU Extension Pesticide Education Specialist

Pesticide applicators should be aware of the 2025 Montana Pesticide Waste Disposal Program sites. Delaying removal of unused pesticide products often leads to corroded containers that pose unnecessary environmental and human health risk. By following a few simple steps applicators can ensure unused pesticides are discarded and disposed of legally and safely in 2025.

Disposing of Pesticide Waste

Applicators should use the Montana Pesticide and Waste Disposal Program if they have unknown pesticide products due to worn or lost product labels, unregistered pesticide products or unusable pesticides. The Montana Pesticide and Waste Disposal Program began in 1994 and has collected more than 796,000 pounds of waste pesticide from more than 1,871 participants since its onset. Common pesticide active ingredients collected include DDT, pentachlorophenol, dinoseb, and strychnine. Costs for participating in the program are significantly lower than other pesticide disposal alternatives. There is no fee for the first 200 pounds. For amounts greater than 200 pounds there is a $1.00 per pound fee with a minimum of $5.00. Dioxins, dioxin precursors, or any product that requires special packing may result in a higher fee.
