Description
Chemical products designed to kill insects. Insecticides can be classified as:
1. Inorganic toxic compounds (e.g., soluble salts of Arsenic, Lead, Mercury, and Copper) are consumed and act as stomach poisons. Silica absorbs the outer waxy covering and desiccates insects.
2. Natural organic compounds (e.g., Pyrethrin, Rotenone, Nicotine, Copper naphthenate, petroleum derivatives) are contact insecticides.
3. Synthetic organic compounds such as chlorinated (e.g., DDT, Aldrin, Chlordane, Lindane) contact insecticides are nonbiodegradable and many have been banned. Organic phosphates (e.g., Parathion, Diazinon, Chlorpyrifos, Dichlorvos, Malathion) are toxic contact insecticides that are still in use.
4. Insect growth regulators (e.g., Methoprene, hydroprene, and Fenoxycarb) prevent larvae from becoming adults.
5. Fumigants (e.g., Sulfuryl fluoride and Methyl bromide) are vapor phase insecticides that penetrate inaccessible locations.
6. Anoxic storage using oxygen scavengers (Ageless, VELOXY) in an airtight container kills all stages of insects (adults, eggs, larvae, and pupae).
Risks
All insecticides are potentially toxic to humans and animals. Pyrethrins, rotenone and methoxychlor are the least toxic because they quickly decompose.
