Permethrin is a broad spectrum insecticide, a chemical used to kill a variety of insects. Permethrin is referred to as a synthetic pyrethroid insecticide because, while manmade, it resembles naturally-occurring chemicals with insecticidal properties, called pyrethroids. Pyrethroids are found especially in chrysanthemums. Pyrethroids are one of the oldest classes of organic insecticides known (
10). They work by quickly paralyzing the nervous systems of insects, producing a quick "knockdown" effect on insect pest populations. Permethrin acts as a stomach poison when it is ingested by insects or as a contact poison through direct contact with target pests. It kills adults, eggs, and larvae, and has a slight repellent effect against insects (
