Unwanted lawn and garden chemicals can be harmful if not disposed of properly. Never place unused or partially used pesticides in the garbage or down the drain. Some older pesticide labels say that these products can be disposed of in the trash, this is no longer allowable, and newer labels no longer suggest it.

Take leftover pesticides to a hazardous waste disposal site.
