Permethrin does not present any notable genotoxicity or immunotoxicity in humans and farm animals, but is classified by the EPA as a likely human carcinogen when ingested, based on reproducible studies in which mice fed permethrin developed liver and lung tumors. [35] A 2018 review failed to link permethrin exposure in humans to cancer. [36]
Permethrin can be applied as a spray. The effects are not limited to mites: lice, cockroaches, fleas, mosquitos, and other insects will be affected. Ivermectin can be prescribed by a medical doctor to rid humans of mite and lice infestations, and agricultural formulations are available for infested birds and rodents. Antibiotic miticides
Cypermethrin is very toxic to cats which cannot tolerate the therapeutic doses for dogs. [6] This is associated with UGT1A6 deficiency in cats, the enzyme responsible for metabolizing cypermethrin. As a consequence, cypermethrin remains much longer in the cat's organs than in dogs or other mammals and can be fatal in large doses.
Pyrethroids are much less toxic in mammals than they are in insects and fish, because mammals have the ability to rapidly break the ester bond in bifenthrin and break the substance into its inactive acid and alcohol components. [2] In humans and rats, bifenthrin is degraded by the cytochrome p450-family. [5]
Permethrin, sulfur, lindane, dicophane, benzyl benzoate, ivermectin and crotamiton are well known ectoparasiticides. [2] Additionally, ectoparasiticides have been used to safely contaminate rhinoceros horns with hopes of it deterring the demand for these horns on the black market.
