Permethrin can be applied as a spray. The effects are not limited to mites: lice, cockroaches, fleas, mosquitos, and other insects will be affected. Permethrin, however, is not known to seriously harm most mammals or birds, as it has a low mammalian toxicity and is poorly absorbed by skin.
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.
Diatomaceous earth will also kill mites by disrupting their cuticles, which dries out the mites.
Dicofol, a compound structurally related to the insecticide DDT, is a miticide that is effective against the red spider mite Tetranychus urticae.
Lime sulfur is effective against sarcoptic mange. It is made by mixing hydrated lime, sulfur, and water, and boiling for about 45 minutes. Lime can bond with as much as four times its weight of sulfur. The strongest concentrate is diluted 1:32 before saturating the skin (avoiding the eyes), applied at six-day intervals.
Nonpesticide miticides act by causing desiccation, but are not a diatomaceous earth (which contain crystalline silica, potentially dangerous by inhalation), but made from a patented mix of food-grade components, one to breach the cuticle and one to ensure rapid, reliable desiccation. They can be dusted as powder or sprayed in aqueous solution.
