Why be Concerned?

• Pesticides, such as insecticides, weed killers, and slug bait, contain toxic ingredients. Often these products are toxic by ingestion, inhalation, and skin contact.
• Mixing pesticide concentrates can expose you to very strong solutions of active ingredients.
• Many pesticides are toxic to pets. Slug bait is especially hazardous to dogs.
• Many pesticides are also highly toxic to birds, bees, and fish. Most insecticides are toxic to all insects, including those that are harmless or beneficial.
• Some pesticides are highly mobile and can contaminate ground water or surface water.
• Despite their misleading name, so-called "inert" ingredients can be toxic, flammable, or corrosive. Sometimes they are more hazardous than active ingredients.
  
• Scientific studies show that pesticides applied to the lawn are tracked in to the home and can be found in carpet dust and on tables, window sills and other surfaces. Children pick up these residues on their hands and transfer them to their mouths.

Disposal

Although local practices may vary somewhat, generally speaking all unwanted pesticides are considered hazardous waste and must be disposed of at a household hazardous waste site. Legally registered products can still be used if desired. Banned or restricted ingredients such as chlordane, pentachlorophenol, and DDT are illegal to use and should be disposed of properly.
