Dust Mite
Scientific Name: Dermatophagoides spp. (e.g., Dermatophagoides pteronyssinus, Dermatophagoides farinae)
Order & Family: Acariformes (Order), Pyroglyphidae (Family)
Size: Approximately 0.2-0.3 mm (too small to be seen with the naked eye)
Natural Habitat
Found in human dwellings, especially in mattresses, bedding, upholstered furniture, carpets, and dust. They thrive in warm, humid environments.
Diet & Feeding
Primarily feed on shed human and animal skin flakes (dander), but also consume pollen, fungi, and bacteria.
Behavior Patterns
Dust mites are microscopic arachnids that avoid direct light. They reproduce quickly in optimal conditions. Their fecal pellets and body fragments are the primary source of allergens. They do not bite or sting.
Risks & Benefits
Potential risks include triggering allergic reactions such as asthma, eczema, and allergic rhinitis in sensitive individuals due to their allergens (fecal matter and body fragments). They provide no direct benefits to humans, as they are primarily considered household pests from a health perspective.
