House dust mites are tiny, microscopic creatures that thrive in warm, humid environments, often found in homes. They feed on dead skin cells shed by humans and pets, making bedding, carpets, and upholstered furniture ideal habitats. These mites are not harmful to most people, but their waste products can trigger allergic reactions and asthma in sensitive individuals. Regular cleaning, such as vacuuming and washing bedding, can help reduce their population and minimize potential health issues related to allergies and asthma.
