Why does pesticide kill insects even after the rain washes it off?

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.

How does the use of antibiotics and pesticides cause resistance in insects and bacteria?
The use of antibiotics and pesticides creates an artificial selection scenario that culls bacteria and insects that cannot survive the treatments. Those micro-organisms and insects that do not succumb to the effects of antibiotics and pesticides survive to reproduce, and their offspring share their resistance to the antibiotics and pesticides that did not kill them. Now the entire population is resistant. Here is an example of how to make a population of insects pesticide resistant (micro-organisms respond similarly to antibiotics): Assumption: Insect Population I has a 99% mortality when exposed to Pesticide P Stage 1: 100,000 Population I insects are treated with Pesticide P Stage 2: Pesticide P treatment kills 99% of Population P Stage 3: 1,000 insects survive and reproduce Stage 4: Population R is 100% resistant to Pesticide P
