Carpet beetles are among the most common insects found in homes around the country. There are many different species of carpet beetles that can be found in different regions. The most common is the "varied carpet beetle" and it lives up to its name by taking on many forms. The mature beetles are around 1/8 of an inch long and have an oval body shape while larvae are typically the same length. Adults are usually brown with colored scales that present in many different patterns.
Carpet beetles are pests that feed off of things in your home that have some sort of animal origin. They could be found in anything from your trash can to a goose-down pillow. They originally acquired the name "carpet beetle" due to common infestations in woolen carpets. Carpet beetles will eat wool fabrics, but they will not infest synthetic fabrics that are commonly used in carpets today.
Infestations most commonly result from wild carpet beetle populations migrating to cooler areas in the heat of the summer. These cooler areas can be anything from a barn to a home. Infestations can start in areas as small as a pocket of household lint in a corner and move outward to the rest of your home.
