The dust in your house is the sum of your environmental accumulations. It is a mixture that can include dried food particles, outside dust, pollen particles, mold spores, fibers, insect parts and droppings, pesticides, hair, shed skin cells, and dried saliva and urine from indoor pets.

What Is It In House Dust That Causes Allergies?
In laboratories around the world a debate has raged for years: Is there an allergen in house dust that is unique to dust, or are the symptoms caused by an allergy to one of the already – recognized agents comprising the dust – the most commonly suggested culprit being the house dust mite? Although the answer is not completely resolved to everyone’s satisfaction, it appears that most allergic reactions to dust are due to an allergy to one of its constituents, most commonly the house dust mite. However, any of dust’s constituents can be the cause of your symptoms: other insects and their droppings (most notably those of the cockroach), as well as animal (cat and dog) dander particles. Unfortunately, many allergic people are genetically disposed to react to more than one component of their house dust. They may, for example, react to mites, mold spores, pollens, and cat saliva.

How To Tell If You Are Allergic To House Dust
If when you vacuum, sweep, dust, and clean (or are present when this is done) you get a runny, itchy, stopped-up nose and a sneezing spell, you are probably allergic to something in house dust. The exact dust components causing your allergy can be determined by allergy testing, either of your skin or your blood serum.
If you are allergic to house dust, your symptoms tend to occur both in and out of the pollen seasons, are worse inside your home than outside, and seem to be more of a bother the longer you are indoors. It is common for dust-allergic symptoms to be worse on awakening in the mornings. Sleeping in a dusty bed or with a dusty pillow or bedding can contribute to your symptoms, as can the ceiling or oscillating fan that keeps the dust in your room suspended in the air while you sleep. Symptoms caused by something in house dust frequently lessen or clear when you go on vacation, then worsen when you return home.
