Dust Mite Allergy Symptoms and Signs

Dust mites are tiny creatures that live in house dust, beds, and carpets. They do not bite. Their droppings and body pieces cause allergies.

If you or your child wake up sneezing, blocked, or itchy, dust mites may be the cause. Symptoms can be worse at night and first thing in the morning.
