A pyrethroid is an organic compound similar to the natural pyrethrins, which are produced by the flowers of pyrethrums (Chrysanthemum cinerariaefolium and C. coccineum). Pyrethroids are used as commercial and household insecticides.[1]
In household concentrations pyrethroids are generally harmless to humans.[1] However, pyrethroids are toxic to insects such as bees, dragonflies, mayflies, gadflies, and some other invertebrates, including those that constitute the base of aquatic and terrestrial food webs.[2] Pyrethroids are toxic to aquatic organisms, especially fish.[3] They have been shown to be an effective control measure for malaria outbreaks, through indoor applications.[4]
