You can pick up an inexpensive microscope from any store that sells toys, a hobby store, or a thrift store and use it to discover whether your home has dust mites.

Wash all sheets, blankets, pillowcases and bedcovers in hot water that is at least 130 F (54.4 C) to kill dust mites and remove allergens. If bedding can't be washed hot, put the items in the dryer for at least 15 minutes at a temperature above 130 F (54.4 C) to kill the mites.
Dust mites are microscopic insects that live in our pillows, furniture and carpets. They're not the same thing as bed bugs. To reduce your exposure to dust mites, follow these tips.

House dust mites are about 0.1–0.4 mm long [2], less than one tenth the size of a bed bug, at least. House dust mites are translucent to white in color and have been described as “globular” in shape [3].
