A pyrethroid is a synthetic chemical that kills most insects. They are similar to the natural chemical pyrethrin produced by the flowers of a chrysanthemum. Pyrethroids are common in commercial products such as household insecticides and insect repellents. They are usually broken apart by sunlight and the atmosphere in one or two days, and do not significantly affect groundwater quality. Pyrethroids are usually combined with piperonyl butoxide a known inhibitor of key liver enzymes. Combined, pyrethroids are toxic to most beneficial insects like bees or dragonflies. There is a strong probablility they are estrogen disruptors.
