Learn how to reduce dust mite population in your bedroom


What’s a Dust Mite?

Dust Mites, are spider like creatures that are so small that you need a microscope to see them. The average mite is about 0.3 mm long. They are not harmful to humans, as they only feed on human and animal dander (dead skin and hair). Humans shed about 10 grams of skin a week providing ample food for these little creatures. Their favorite place is in the bedroom, where people spend a third of their lives, but they can be found in most places that humans lounge, furniture, carpets, stuffed animals, pillows, and even in the car. Depending on the temperature and humidity, a mattress can be host of up to 10 million of them and carpets can have colonies of 100,000 living in one square meter. They can defecate (poop) up to 20 times a day, this can build up to quite a bit, so that over 10 years a mattress can double its original weight due to the accumulation of dead dust mites and their feces, or a pillow”s weight can also double in weight in as little as two years due to same reason.
