Dust mites are unwelcome guests in every home. These microscopic insects infest our bedding, carpeting, and furniture. Although dust mites can survive in most climates, they thrive and multiply best in warm and humid environments. Since they feed off of dead skin flakes and dander, they make their homes easily anywhere people and animals live. The dust mites themselves are a concern as they are the source of the allergen, but it is actually the proteins (DERp1) in their waste and body fragments that cause the most discomfort as these are highly allergenic.
