The problem is not only in your carpets. Upholstery and mattresses also provide the ideal breeding ground for dust mites, which can cause allergic reactions, particularly in small children and asthmatic.

You shed up to 10,000 million scales of dead skin tissue each day. Much of this goes into the bed and takes bacteria with it. To this you add ¼ pints of body moisture each night during ordinary sleep. All this leads to ideal conditions for the dust mite. There are an estimated 42,000 dust mites per ounce of mattress dust in the average double bed.
