Dust Mite

Natural Habitat

Dust mites are microscopic arachnids that thrive in warm, humid environments. They are commonly found in human dwellings, particularly in bedding, upholstered furniture, carpets, and curtains, where they feed on shed human and animal skin flakes.

Diet & Feeding

Dust mites primarily feed on dead skin cells shed by humans and pets, as well as pollen, fungi, and bacteria.

Behavior Patterns

Dust mites are microscopic and generally invisible to the naked eye. They are not parasitic on humans, but their presence can trigger allergic reactions. They reproduce quickly in optimal conditions (20-25C and 70-80% humidity) and their life cycle from egg to adult is about 3-4 weeks.

Risks & Benefits

Potential Risks: Dust mites are a common cause of allergies and asthma attacks. Their fecal matter and decaying body parts can become airborne and inhaled, leading to symptoms like sneezing, runny nose, itchy eyes, skin rashes (eczema), and respiratory problems. They do not bite or transmit diseases. Potential Benefits: In their natural ecological role, they contribute to the decomposition of organic matter, but within human indoor environments, they are largely considered a pest due to allergic reactions.
