Which type of pest feeds primarily on shed skin scales?

House dust mites are microscopic creatures that thrive in environments where organic debris is available as food, and their primary diet consists of the shed skin scales of humans and pets. These skin flakes, which are shed routinely, provide the necessary nutrients for the dust mites to grow and reproduce.

The significance of house dust mites in pest control stems from their association with indoor allergies and respiratory issues, as they can produce allergens that contribute to conditions like asthma. Understanding their feeding habits is crucial for managing indoor environments and reducing allergen exposure.

Other options, while they also represent different pest groups, do not primarily feed on shed skin scales. Clover mites tend to feed on plant material, centipedes are carnivorous and consume other small pests, and dermestid beetles, although known for infesting dried organic materials (including animal remains), are not primarily linked to feeding on shed skin scales like the house dust mites.
