Font Size

For creatures you can't even see, dust mites can stir up a lot of trouble. About 20 million Americans are allergic to these little bugs. When you're one of these people, you may feel as if you have an endless cold or even asthma.

Medication can help, and you can also take simple steps to keep the dust mites away.

Staying Active and in Control Despite Their Allergies

For people who have allergies, the challenges of remaining physically active can easily outweigh the benefits to their health and mental well-being. Running, swimming, and even gardening -- how enjoyable can these activities be when just taking a breath is so exhausting? But having seasonal allergies doesn't mean you have to become a shut-in.

Symptoms to Watch For

Dust allergy symptoms are similar to those of pollen allergies:

'The Dirt' on Dust Mites

To get rid of these tiny creatures in your home, keep in mind their living habits. They prefer temperatures of 70 F or higher and humidity of 75% to 80%. They can't survive in colder, drier places.

In the U.S., dust mite allergies peak in July and August, when dust mite populations are high because of warm weather.

Dust mites like to eat dead skin from pets and humans. You probably shed enough skin a day to feed a million dust mites. Flakes of dead skin in carpeting, beds, and furniture are like tasty snacks for them.

What Causes Dust Allergies?

It sounds nasty, but it's true: One piece of dust can contain pet dander, pieces of dead cockroaches, and mold spores, along with dead skin and dust mites.

Both cockroaches and pet dander are common allergy triggers, too. Cockroach waste, saliva, and body parts are a problem in some homes, particularly in the southern U.S.

How Can I Prevent Symptoms?

The best strategy is to limit your exposure to dust.

Start in the bedroom, where you probably spend the most time. Large numbers of dust mites can gather in mattresses, bedding, and upholstered furniture.

Wear a mask while cleaning, too.

Bedroom Dust-Busting Tips

Put airtight, plastic dust-mite covers on pillows, mattresses, and box springs.

Use pillows filled with polyester fibers instead of kapok or feathers.

Wash bedding in very hot water (over 130 F) once a week. The water needs to be this hot to kill dust mites. Dry the bedding in a hot dryer.
