The acute reference dose (RfD) for bifenthrin is 0.328 mg/kg bodyweight/day. The chronic reference dose (RfD) for bifenthrin is 0.013 mg/kg bodyweight/day. [4] Bifenthrin was included in a biocide ban proposed by the Swedish Chemicals Agency, because of its carcinogenic effect. [18] This was approved by the European Parliament in 2009. [19]

Allethrin I (R = −CH 3) Allethrin II (R = −COOCH 3). The allethrins are a group of related synthetic compounds used in insecticides.They are classified as pyrethroids, i.e. synthetic versions of pyrethrin, a chemical with insecticidal properties found naturally in Chrysanthemum flowers.
Pyrethroid: 1 – 2 days Safened by repellency under arid conditions. Permethrin is also the active ingredient in insecticides used against the Small hive beetle, which is a parasite of the beehive in the temperate climate regions. Highly toxic Cypermethrin [55] Ammo, Demon, Raid, Viper Pyrethroid: Less than 2 hours
Pyrethroids are classified based on their mechanism of biological action, as they do not share a common chemical structure. Many are 2,2-dimethylcyclopropanecarboxylic acid derivatives, like chrysanthemic acid, esterified with an alcohol. However, the cyclopropyl ring does not occur in all pyrethroids.
Almost 2 million men and women who served in Iraq or Afghanistan are flooding homeward, profoundly affected by war. Their experiences have been vivid. Dazzling in the ups, terrifying and depressing in the downs. The burning devotion of the small-unit brotherhood, the adrenaline rush of danger, the nagging fear and loneliness, the pride of service.
Raid derivatives aimed at particular invertebrate species can contain other active agents such as the more toxic cyfluthrin which is also a pyrethroid. [2] As of 2019 Raid Ant & Roach Killer contains pyrethroids, imiprothrin , and cypermethrin ; [ 3 ] other products contain tetramethrin and prallethrin as active ingredients. [ 4 ]
