Mite bites can cause skin lumps and rashes and, occasionally, more serious reactions, Dr. Merchant says.
Among outdoor mites, the only type that frequently bites people is the chigger. The word “chigger” applies to a particular species of mite that bites during its larval stage of development, and their bite produces an intensely itchy red welt, Merchant explains. “There are not too many other mite problems outdoors,” he adds.

When it comes to indoor mites that bite or cause health issues, Merchant says most spring from animal nests. “Some mites will infest the nests of birds and rats and mice, and when they become abundant, they’ll leave that site and sometimes wander into the house and bite people,” he explains. In most cases, the bites of these mites cause an itchy skin rash, which may feature small lumps or pimples.
“The skin might be very itchy or red for a few days, but then that will taper off,” Merchant says of mite bites. Ice and anti-itch creams like hydrocortisone can help control the swelling and itching. But those symptoms should resolve within a week, he says. (Nearly all species of biting house mites cannot live on human beings, and so they don’t “infest people,” he adds.)
There is one outlier: scabies. These mites infest a person’s skin in order to lay eggs and feed, and are usually only passed by direct person-to-person contact. (4) Like other mites, scabies tend to cause an itchy, pimply red rash. But unlike other mites, those rashes will continue to appear unless the person gets medical treatment, usually a prescription-only skin cream or lotion designed to kill scabies.
Dust mites can cause allergies in some people, but these tend to be of the mild, seasonal allergy variety — stuff like a runny nose, sneezing, and itchy eyes. (5) Over-the-counterand prescription allergy meds can help quell dust mite allergies.
