Dust Mite Allergy Treatment, Symptoms and Diagnosis

Dust mite allergies are a common concern for many patients who seek care at Advanced ENT and Allergy. These tiny organisms are found in nearly every home and can trigger uncomfortable symptoms that linger throughout the year. Because they live in places like mattresses, pillows, and carpets, dust mites are hard to notice, but their impact on your health and well-being is not. If you’re waking up with a stuffy nose, coughing at night, or noticing rashes or hives on your skin, dust mites could be part of the problem.
This post explains what dust mites are, why some people react to them, and what symptoms to watch for. It also details how our specialists diagnose dust mite allergies and what kinds of treatments and prevention strategies can bring lasting relief. The good news? With the right care and support, it is possible to reduce symptoms and feel better at home.

What are Dust Mites?

Dust mites are microscopic animals (anthropods if we’re being literal) that live in household dust. To be clear, they are not parasites and do not bite. So why do they cause congestion and other symptoms? Because their waste products contain proteins that can trigger allergic reactions. These allergens are easily inhaled and can accumulate in soft surfaces throughout the home. Because dust mites thrive in warm, humid conditions, they are particularly common in bedding, carpets, curtains, and cloth-covered furniture.
Unlike seasonal allergens such as pollen, dust mites are a year-round problem. According to recent studies, between 20 million and 35 million Americans are allergic to dust mites. The consistent presence of these allergens makes managing symptoms especially important, particularly for patients with preexisting respiratory conditions like asthma.

Symptoms of Dust Mite Allergies

Dust mite allergies can appear in a variety of ways. Most commonly, patients experience respiratory symptoms such as:

• Persistent sneezing
• Nasal congestion
• Runny nose
• Postnasal drip
• Itchy, watery eyes

Dust Mite Allergy Rash and Hives

Respiratory symptoms are only one component of the reactions that dust mites can cause. Many individuals also develop skin reactions that include a rash or hives. The rash may appear as red, itchy patches, particularly on areas of the body that come into contact with cloth-covered furniture like bedding or a couch. Hives are raised, inflamed welts that can occur suddenly and may appear in different places around the body.

Dry Cough From Dust Mites Allergy

Another common symptom is a chronic, dry cough. In some cases, it can mimic or exacerbate asthma. Children and adults alike may experience increased coughing at night or after waking up. In patients with asthma, dust mite exposure can trigger shortness of breath, wheezing, and chest tightness.

How Long Do Dust Allergy Symptoms Last?

Dust mite allergy symptoms often resemble those of a cold but tend to persist over long periods, especially when the individual is indoors. Patients frequently report that symptoms are worse in the morning after sleeping in bedding where dust mites are most concentrated.

Dust Mite Allergy Diagnosis

Accurate diagnosis of a dust mite allergy begins with a comprehensive medical history. Providers at Advanced ENT and Allergy consider the duration and timing of symptoms, lifestyle habits, and home environment. If an allergy is suspected, our physicians may recommend a skin prick or blood test. These tests identify immune responses to specific allergens, including dust mites.
Skin prick testing involves applying small amounts of allergens to the skin. The test site is usually on the forearm or back, and the tester then monitors the area for a reaction. A slightly raised and red bump at the point of the test indicates an allergic response. Blood tests can also measure specific IgE antibodies to dust mite proteins, offering another diagnostic tool when skin testing is not feasible.

Dust Mite Allergy Treatment Options

Once diagnosed, treatment typically begins with medications to relieve symptoms. These may include antihistamines, nasal corticosteroids, and leukotriene modifiers. For patients with more severe or persistent symptoms, immunotherapy may be recommended. This involves exposing the body to gradually increasing doses of allergens. Doing so helps the patient to build a tolerance. Allergy shots and sublingual allergy drops are both effective methods offered by Advanced ENT and Allergy.
These treatments significantly reduce symptoms and medication use in patients with a dust mite allergy. What’s more, the benefits often last for years after treatment is completed.

Dust Mite Prevention and Environmental Control

While eliminating dust mites entirely may not be possible, there are a number of ways to greatly reduce their presence. Controlling environmental conditions is critical to minimizing exposure.  Consider these helpful tips:

• Wash all bedding weekly in water at least 130°F
• Use dust-mite-proof covers on pillows and mattresses
• Remove or replace carpeting with hard flooring
• Vacuum frequently with a vacuum equipped with a HEPA filter
• Maintain indoor humidity below 50% with a dehumidifier
