   Resources >> Disposal of pesticides and fertilizers

Many lawn and garden chemicals can be harmful if improperly disposed of when no longer wanted.

Pesticide disposal

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 recommended, and newer labels no longer suggest it.

Take leftover pesticides to a hazardous waste disposal site.

  • All counties in Washington and Oregon have hazardous waste collection programs for unwanted pesticides.
  • These may include a permanent collection site or periodic collection events.
  • Contact your county health department, public works department or solid waste agency for hours and locations.
  • For direct contacts in specific areas, see below.

Fertilizer disposal

The best thing to do with unwanted fertilizers is

  • Use them up as directed.
  • Give them to someone who can use them.
  • Except for weed-and-feed products: these contain pesticides and should be taken to a hazardous waste collection site.
