Dust mites are tiny, microscopic relatives of spiders and ticks that lurk around our homes. They feed on the dead skin cells that we shed. Due to their diet, dust mites are commonly found in the areas where dust and dead skin cells accumulate the most. This includes carpets, mattresses, bedding, curtains, stuffed animals and furniture.
Dust mites are allergenic- meaning materials from their skin and fecal matter can cause allergic reactions and symptoms, especially in people with allergies and asthma.
Common dust mite allergy symptoms include:
- Runny nose
- Stuffy nose
- Itchy nose, mouth or throat
- Postnasal drip
- Red, Itchy skin
- Itchy, red or watery eyes
In people with asthma, symptoms can include:
- Chest tightness or pain
- Difficulty breathing
- Shortness of breath
It is impossible to completely eliminate dust mites, even in the cleanest homes. However, there are ways to limit exposure and reduce the risk of symptoms. Here are a few:
- Wash bedding weekly in hot water
- Cover mattresses and pillows in zippered dust-proof covers
- Dust regularly
- Avoid carpeting if possible or vacuum frequently
- Use certified allergen capturing filters in vacuums and air conditioners
- Keep the humidity levels in your home under 50% (Dust mites thrive in environments with humidity levels of 70 to 80%)
If symptoms persist, relief can be achieved by taking over-the-counter or prescription decongestants, antihistamines or nasal corticosteroids. Immunotherapy in the form of allergy shots or sublingual (under-the-tongue) tablets can also be effective.
