House Dust Mite Allergy

What is a Dust Mite allergy?

A dust mite allergy is not in fact an allergy to dust mites. The allergic reaction is caused by exposure to dust mites cast skins, faecal material and secretions which are found in household dust.

Those with dust mite allergies often suffer the most inside their own homes or in other people’s homes.house dust mites

Their symptoms often worsen during or immediately after vacuuming, sweeping and dusting. The process of cleaning can stir up dust particles, making them easier to inhale.

There are many substances in dust which can trigger allergies, including animal dander, mold spores and pollen.

The most common allergens within house dust are produced by dust mites. Dust mites are tiny creatures that live in close association with humans. Their primary food is skin scales (dander) shed from humans and animals.

Most homes are likely to have detectable levels of house dust mites and their allergy inducing fragments. These fragments from the dust mites contain powerful allergens which are found within their cast skins, faecal material and secretions.

It is these allergens that bring the many symptoms, discomfort and suffering to people who are sensitive to them.
