Dust mite

Found indoors worldwide, primarily in carpets, mattresses, upholstered furniture, and bedding where humidity is high.

Feeds on dander (dead skin cells) shed by humans and animals, as well as some mold.

Thrive in warm, humid environments (70-80% humidity); they do not drink water but absorb it from the air. Their life cycle from egg to adult takes about 1 month.

Risks include being a major trigger for asthma, eczema, and allergic rhinitis due to proteins in their waste. They provide no significant benefits to humans.
