This document is intended to be educational in nature and helpful to consumers for making decisions about pesticide use.
Labels provide directions for the proper use of a pesticide product.
Be sure to read the entire label before using any product. A signal word on each product label indicates the product's toxicity after a single dose. Permethrin is a pyrethroid. It is a synthetic chemical similar to the natural insecticide pyrethrum which comes from the chrysanthemum plant, but it remains effective for longer periods of time. Pyrethroids work by quickly paralyzing the nervous system of insects.
