Pyrethroids are similar in structure and function to pyrethrins. Both are very effective against insects at very low doses and work very rapidly.

Pyrethroid insecticides vary greatly in their toxicity, residual life and efficacy against pests. However, as a group, they are less toxic than the organophosphates and carbamates products they have replaced. Pyrethroids are considered broad-spectrum pesticides because most are active against a wide range insects ants, cockroaches, fleas, true bugs, aphids, scales, beetles, caterpillars, flies, and wasps.
