Follow the same precautions used when applying the pesticide. Repeat this procedure two more times. Then discard the container with your solid waste. Do not triple rinse pesticide containers in a household sink. Never pour leftover pesticides down the drain.
Pesticides can interfere with the operation of the wastewater treatment plant or septic system.
Never pour pesticides into storm drains. These often lead directly to area streams and rivers. Give a leftover pesticide to someone who can use it up if the product is in its original container and the directions are legible. Do not exchange a banned pesticide or give a restricted pesticide to a person who is not licensed in its use. If a pesticide is banned, restricted, chemically deteriorated, or if you cannot use it, then it must be secured and held for a household hazardous waste collection.
