Dust mites do not bite, reports the Texas A&M AgriLife Extension. Only scabies mites cause irritation and itching by biting. The only way to cure scabies is through a prescription ointment or cream that kills the mites, which is applied for eight to 14 hours, according to WebMD.
While dust mites do not infest humans, they shed their skin and feces, which can provoke an allergic reaction in some people, warns the Texas A&M AgriLife Extension. To eliminate potential allergens, reduce indoor humidity, and vacuum with a HEPA filter on a consistent, frequent basis. Dust and dander in furniture can support or help spread dust mite populations. Some people also mistake small static charges for mite bites.
The only other mite that infests humans is the hair follicle mite, says the Texas A&M AgriLife Extension. Unlike the scabies mite, it does not bite and is generally considered harmless, but its presence has been associated with acne.
When dealing with scabies, WebMD recommends treating everyone in the household, especially if there is any close physical contact involved. The mites spread through close skin-to-skin contact or through shared personal items or bedding. It can take four to six weeks for symptoms to appear.
