Air Duct Cleaning - what are dustmites?

Dust mites are tiny bugs that live in your home. They measure about 1/100th of an inch in length, which is smaller than the period at the end of this sentence. Dust mites feed off of pet and human dander (dust), and their waste is a major cause of allergies and asthma. In children who have asthma, dust mites can cause them to wheeze more and need more asthma medicine. So, cutting down the number of dust mites in the home is an important step if your child has allergies or asthma.
