Carpet beetles do not bite humans, but their larvae can cause skin irritation that’s often mistaken for bites. These tiny, bristly larvae have barbed hairs that can lead to allergic reactions in sensitive individuals, resulting in red, itchy welts or rashes. While the irritation may resemble bug bites, it’s actually a response to contact with the hairs or shed skins, not an actual bite. Adult carpet beetles are harmless and primarily feed on pollen, but their larvae can damage natural fibers like wool, fur, or leather in carpets, clothing, and upholstery.

While many pests like rats, mice, ants, cockroaches, silverfish, and bed bugs can damage your home, termites are among the most destructive. By sheer dollar amount, the damage from a bad termite infestation is unparalleled, as they can ruin walls, floors, roofs, and wooden support materials, potentially requiring massive reconstruction. Other highly destructive pests include rodents, carpenter ants, and bees that build hives within walls. If you spot signs of termites or other pests, you should hire an exterminator immediately.

If you’ve ruled out small cockroaches, some other bugs you might mistake for bed bugs are carpet beetles, bat bugs, and booklice. However, they’re usually found in different parts of the home. Carpet beetles are found in fabrics and carpets, bat bugs live in attics, and booklice dwell around books and damp areas.

This depends on if their needs are being met. They'll likely return night after night if they have access to food, water, and adequate shelter. If this changes, they’ll look for another roosting spot. This is why bright lights and other dissuading factors often work when removing bats from a property.
