Description
A colorless, toxic liquid Insecticide that has been commonly used in plastic insect strips. Dichlorvos has a high vapor pressures and when it is impregnated in the plastic strips, it will slowly evaporate over a three month period. It is most effective against flying insects and only effective for cockroaches in a sealed container (Zycherman and Shrock 1988). Dichlorvos functions as a cholinesterase inhibitor. In the presence of water, dichlorvos can decompose. Some metals (Iron, Steel, Copper, Brass, Tin, Zinc, Lead, and Silver) have tarnished when exposed to the vapors from dichlorvos strips (Zycherman and Shrock 1988). In 1995, the use of dichlorvos was restricted for all applications except for impregnated strips used in outdoor insect traps.
