Mites are tiny arthropods, related to ticks. Several types of mites can be found in homes and of these a few may bite humans. Most mites are harmless predators of insects, or feeders on decaying plant material. Some pest mites feed on stored products like cheese and grain. Others are merely nuisance pests, accidentally entering homes from their normal outdoor habitat. Only a few mite species are parasitic on birds or mammals; but these can occasionally become biting pests in homes. Identifying the type of mite and/or likely host is the first step in solving an indoor mite infestation.
HUMAN BITING MITES
Several types of mites are associated with cases of skin dermatitis in humans. The tropical rat mite, Ornithonyssus bacoti, is one of the most common house invading species. The tropical fowl mite, Ornithonyssus bursa, and northern fowl mite, Ornithonyssus sylviarum, are also frequently encountered in homes. The latter two species are found principally on domestic or wild birds. The house mouse mite, Liponyssoides sanguineus, may also be found in structures with house mouse infestations. The tropical rat mite is a parasite on rats. Although none of these species are truly parasitic on humans, they bite people readily, often producing dermatitis and itching.
Rat and bird mite infestations occur in structures where rat or bird nests are located. Mites do not hop or fly, but may crawl several yards from an infested nest. Most often, bites are noticed only in certain rooms of the structure, presumably close to the rodent or bird nests. Unlike bed bugs, neither rodent or bird mites “hitchhike” on people or on belongings to other locations.
Infestations are sometimes first noticed following extermination, or after the natural hosts have died or left the structure. Infestations may also occur where heavy mite infestations have developed around a rodent or bird nest. Occasionally rodent or bird mites may be found on rodents kept as pets.
Care must be taken of stored materials, whether food, clothing or carpets,Put Appropriate pesticides to them Seal homes against rodents all vents and electric service entry points should be tightly closed with rodent-proof metal hardware cloth, metal flashing, or copper wool. Entry points around chimneys and between loose shingles should also be checked. Doors and windows should seal tightly. House mice will enter structures near the ground, especially under poorly-sealed doors. Rodent proofing must include the smallest entry holes. Mice can enter a home through a hole as small as a dime; rats can enter through a hole as small as a quarter.

Methods of control include Fumigation, Insecticides , and Mechanically preventing entry to buildings.
