    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.

    Summer Sinus Problems

    If you’re among the 37 million Americans who suffer from sinus problems, you know just how miserable the symptoms can make you feel. The congestion. The facial pain. The postnasal drip-drip-drip. Summer often brings a bit of a respite, as the cold viruses that trigger most cases of sinusitis are less active in warm weather. And, experts say the sinus problems that do crop up in summer can often be avoided -- if you take these six precautions:

    Symptoms to Watch For

    Dust allergy symptoms are similar to those of pollen allergies:

    • Red, itchy, watery eyes
    • Runny, itchy, stuffy nose
    • Sneezing

    '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.
