Dust mite allergy Diagnosis & treatment

Specific IgE Blood TestBlood tests are helpful when people have a skin condition or are taking medicines that interfere with skin testing. They may also be used in children who may not tolerate skin testing. Your doctor will take a blood sample and send it to a laboratory.

If you continue to have allergies despite dust mite prevention, see an allergist for help. The key difference though is that bedbugs literally bite humans and feed off of their blood. Dust mites are difficult to get rid of completely, but removing as many as possible from your home can help prevent allergic reactions. The more you stay indoors, the more you may be prone to dust mite complications.

To manage mite populations, reduce the humidity below 70% and thoroughly vacuum mattresses, carpets, sofas, and chairs. Very sensitive individuals should encase their mattresses in plastic. Use drapes that can be washed and change bed clothing frequently. Vacuuming does not always remove all the live mites and Korsgaard (1982) stresses reducing humidity over sanitation.

What can you do to reduce dust in your home?

It can reduce the course of allergic disease by changing your body’s immune response to allergens. Dust mites can live in mattresses, your bedding, upholstered furniture, carpets, or even curtains. How long they live depends on their environment but it can be anywhere from one to three months.

Studies show that more dust mites live in your bedroom than anywhere else in your home. Whether it's things that are piling up or knickknacks on display, dust will accumulate if you're not moving and cleaning each item often. If you're keen on getting rid of as many dust mites as possible, it's often best to remove wall-to-wall carpeting.

Use Natural Oils to Kill Dust Mites

If you’re unable to control the temperature, Craddock says a dehumidifier can help keep your space dry, which isn’t as livable for mites. Dr. Parikh suggests visiting a board-certified allergist or immunologist to determine if you have an allergy to dust mites. Once your allergy is confirmed, you can work with your healthcare provider to determine if immunotherapy treatment is the best option for you. Guidelines for the management of house dust mite hypersensitivity in atopic dermatitis remain unclear and inconsistent due to low-quality clinical trials.

HEPA filters can also be used within portable air cleaners, placed in bedrooms and other critical areas of the house. The value of such portable room air cleaners may be marginal, however, especially in rooms with good ventilation. The second approach often done in conjunction with patient therapy is to minimize exposure to the mites and their allergenic materials inside the home. This is not a simple process and usually requires significant effort and expense.

Add Protective Coverings to Mattresses

Sensitivity to house dust mites and their allergenic proteins can be confirmed by an allergist-immunologist, via a skin and/or blood test. Sublingual (under-the-tongue) immunotherapy (SLIT) is a way to treat dust mite allergies without injections. This exposure improves tolerance to the dust mites and reduces symptoms. SLIT tablets that treat dust mite allergy were approved by the FDA in 2017. High humidity levels provide the perfect environment for dust mites and mold colonies to thrive. Also, high humidity levels make dust particles stick to each other, making them much harder to remove.

The effectiveness of eradication and desensitisation interventions remains uncertain and should only be considered in patients with atopic dermatitis and proven house dust mite hypersensitivity. To diagnose a dust mite allergy, your doctor may give you a physical exam and discuss your symptoms. If your doctor thinks you have a dust mite allergy, they may suggest a skin or blood test. If you have symptoms year-round, you could have a dust mite allergy. A 2014 study found clove oil can help to get rid of dust mites.

The oil can be diffused into the air or combined with water and sprayed on a mattress, carpet, or fabric surface. Always test in a small area to make sure the oil won't leave a stain. Another option is to combine a few drops of oil with baking soda, sprinkle it over a surface, leave it for at least an hour, and then vacuum it away. While a steamy bathroom can usually be cleared of moisture quickly with a venting fan, other factors can contribute to the humidity level in a home—including leaky windows, damp crawl spaces, and improper ductwork.

Dust mites themselves are allergenic, meaning they can cause allergies. They also leave behind skin and fecal matter that may also trigger allergies. Dust mites are one of the most common allergy and asthma triggers that lurk inside your own home. Many medications are available to manage or treat an allergic reaction, including topical steroids and antihistamines that can relieve symptoms of itching, sneezing and rhinitis. The first line of action if you suffer, says Wu, is allergen avoidance.

As mentioned earlier, dust mites require high relative humidity for their survival. It's doubtful that the humidity levels found within air ducts are high enough to support ongoing mite development. Removing heavy accumulations of dust and filth from air ducts may be of some benefit, but should be considered secondary to allergy abatement measures 1-3 listed above. House dust mites have a difficult time surviving when the relative humidity is below 50 percent.

House dust mites can live in the soft furnishings and vents of motor vehicles, so similar cleaning measures inside these is also important. Note that the NIH does not recommend taking any measures to decrease exposure to dust mites or any allergen for people who aren't sensitive to them. The House Dust Mite's life cycle begins as an egg, progressing to larval and nymph stages before reaching adulthood. These tiny creatures thrive in dust within homes, feeding on organic detritus like shed human skin cells, and reproduce rapidly in humid environments. Instead of redistributing dust mites into the air with a feather duster or dry cleaning method, Craddock says a damp microfiber cloth with water or an all-purpose cleaner is great to capture dust and mites from harder surfaces. They prefer dark, soft surfaces with high humidity, which is why your clothing, pillows, toys, and other bedroom items tend to have a high volume.

Allergies develop to the house dust mite droppings which can persist after house dust mites have died. Dust mites are microscopic, insect-like pests that commonly live in house dust. They feed on flakes of dead skin, or dander, that are shed by people and pets. These tiny creatures are a big source of allergens and can worsen allergies and asthma. Dust mites can live in mattresses, bedding, upholstered furniture, carpets, and curtains in your home.

Regular cleaning to minimize dust in the home is imperative, especially for those with allergies. Dust mites don’t truly bite, but they can cause rashes and other allergy symptoms. Regularly washing your bedding and vacuuming floors may help get rid of dust mites, while antihistamines, decongestants, or allergy shots may help ease itching and discomfort. Conventional pesticides, such as those utilized by pest control firms or sold to homeowners in grocery and hardware stores, are not to be used for control of house dust mites. Remove rugs and carpets to wash in hot water or vacuum carpeted areas you can’t remove, Dr. Purvhi recommends.
