Best Answer

The residual effect of active ingredients is the reason why pesticides kill insects even after washed away by rainfall. Some insecticides have to be applied after natural or supplementary moisture since the insect killer's ingredients do not have long-lasting after- or side-effects. Other insecticides, such as Talstar, will remain effective for three months regardless of irrigation or precipitation.
