Dust Mites and Allergies

If you suffer from asthma or allergies, a tiny creature that lives in your home could be causing these issues for you. While you can't see them, you might be experiencing an allergic reaction to them. They're known as dust mites, and they live in a lot of homes all over the world.

What Are Dust Mites?

Dust mites measure only around a quarter to a third of a millimeter. They're so small, you can't see them with your naked eye. They look like white bugs under a microscope. They're not insects though, because they have eight legs - they're actually arthropods, like spiders.

They thrive in 68 to 77 degree F temperatures. They also like 70% to 80% humidity levels. There are a minimum of 13 species of mites, and they're very well adapted to your home's inside environment. They mostly feed off of the tiny human skin flakes individuals shed on a daily basis. And, your dead skin flakes can make their way into inner layers of:

  • Carpets
  • Furniture
  • Stuffed toys
  • Mattresses
  • Bedding
  • And more

What Is a Dust Mite Allergy?

A dust mite allergy is a type of allergic reaction to dust mites, which commonly live in your house dust. The physician might suspect you have a dust mite allergy based on your answers to certain questions about your house and on your symptoms.

What Are the Symptoms of an Allergy to Dust Mites?

  • Runny nose
  • Sneezing
  • Nasal congestion
  • Red, itchy, or watery eyes

  • Itchy roof of mouth, nose, or throat
  • Facial pain and pressure
  • Frequent rubbing of the nose in children

Your dust mite allergy could range from being mild to severe. With a mild dust mite allergy case, it might cause watery eyes, an occasional runny nose, and sneezing. But, in more severe cases, it might be chronic (ongoing), and result in persistent cough, sneezing, facial pressure, congestion, or severe asthma attack.

How Is an Allergy to Dust Mites Diagnosed?

Your physician might use a lighted tool to check the lining of your nose, and confirm if you're dealing with a dust mite allergy.

They may order some tests, such as an:

  1. Allergy Skin Test

The physician might recommend an allergy test to see what you're allergic to. They might refer you to an allergy specialist for the test. Very small amounts of purified allergen extracts, which include a dust mite extract, are pricked into the surface of your skin for this test. This is typically performed on your forearm, but it could be performed on your upper back.

The doctor will then observe your skin, and after 15 minutes will check for signs of allergic reaction. If you do have dust mite allergies, you'll develop an itchy, red bump where the doctor pricked the dust mite extract into your skin.

  1. Allergy Blood Test

Some individuals can't undergo skin tests because they take certain medication, or have a skin condition that could impact the results. As an alternative, the physician might order a blood test for screening for certain allergy-causing antibodies to a variety of common allergens, like dust mites. The test should also show how sensitive you are to a particular allergen.

  2. Leukotriene Receptor Antagonists: These block the action of essential chemical messengers (except histamine) that are involved in allergic reactions.
  3. Nasal Corticosteroids: These are a type of nose spray, and help decrease nose swelling and block allergic reactions. They're most effective for allergic rhinitis, since they can decrease all symptoms, which includes nasal congestion.

This means they might consider allergy shots (immunotherapy), which is a long-term treatment that could help reduce or prevent the severity of your allergic reaction. It could decrease the course of allergic disease by altering the immune response of your body to allergens.
