| pyrethrin |
One of the family of individual chemicals present in pyrethrin which give it insecticidal properties. Increasingly the term is also used in reference to synthetically manufactured chemicals which are similar to natural pyrethrins. Some of these synthetic pyrethrins are actually much more toxic and persistent than natural pyrethrins. Pyrethrins are commonly used in aerosol sprays for controlling fleas, ants, flies, bees, and other common household insects.
