Carpet beetles, a common household pest, can damage fabrics, carpets, and furniture. The larvae of these beetles are the most destructive stage in their lifecycle, often responsible for the majority of damage. In this guide, we will cover what carpet beetle larvae look like, their impact and how to get rid of them. Visit our Species, Control, and DIY Guide sections for additional resources on carpet beetles and ways to tackle a carpet beetle infestation.The eggs hatch in around 6 to 10 days, with larvae immediately starting to feed. Early detection is critical, as the larval stage can last 2 to 3 months, leading to rapid population growth.If you notice signs of an infestation despite these measures, consider consulting a professional pest control service.

What is a Carpet Beetle?
A carpet beetle is a small, oval-shaped insect that belongs to the family Dermestidae. Adult carpet beetles are typically 1/8 to 1/4 inch long and may be brown, black, or mottled with patterns. While adult carpet beetles are harmless, their larvae are destructive, feeding on natural materials such as Wool, Silk, Leather, and Cotton.Carpet beetles commonly infest areas like carpets, furniture, clothing, and stored fabrics, causing noticeable damage.What Does Carpet Beetle Larvae Look Like?

-
Movement: Crawl slowly, often hiding in corners, under furniture, or within carpet fibers.
What Do Carpet Beetle Eggs Look Like?
Carpet beetle eggs are tiny and often hidden, making them hard to detect. Look out for things with following physical appearance:Characteristics of Carpet Beetle Eggs
-
Size: Approximately 1mm in diameter, barely visible to the naked eye.
-
Shape: Oval-shaped with a smooth surface, ensuring they can adhere to hidden surfaces.
-
Color: Initially white or translucent, turning opaque as they mature.
-
Location: Found in secluded spots like cracks, crevices, carpets, and closets, providing easy access to food for larvae upon hatching.
Where Do Carpet Beetle Larvae Come From?
Carpet beetle larvae originate from eggs laid by adult carpet beetles in quiet, undisturbed areas of your home. Common sites include carpets, upholstered furniture, woolen fabrics, and stored items like clothing or blankets. Once hatched, the larvae feed on natural fibers, gradually causing damage.Adult carpet beetles are often drawn to light and enter homes through windows, doors, or small cracks. Inside, they lay eggs in locations rich in food sources, such as wool, silk, leather, or feathers, ensuring their larvae have ample nourishment to grow.Life Cycle of Carpet Beetle
Managing a carpet beetle infestation requires an understanding of its life cycle. The larvae stage, in particular, is the longest and most destructive phase, causing significant damage to household items.Larval StageThe larval stage lasts several months to over a year, depending on temperature and food availability. During this time, the larvae feed continuously on natural fibers like wool, silk, and feathers, leaving behind visible damage.Pupal StageAfter completing their growth, the larvae transition into the pupal stage. This is a transformative period where the larvae develop into adult beetles, typically lasting a few weeks.Adult StageOnce they emerge as adult beetles, their primary role is reproduction. Adults lay eggs in areas rich in food sources, continuing the life cycle. The complete process from egg to adult can take a few months to a year, depending on the species and environmental conditions.What Do Carpet Beetle Larvae Eat?
Carpet beetle larvae are destructive pests that feed on natural fibers like wool, silk, leather, feathers, and hair. They are commonly found in carpets, clothing, furniture, and stored natural fabrics, occasionally infesting pantry items like grains or pet food. Their preference for keratin, a protein in natural fibers, causes visible damage such as holes in fabrics and bald spots on carpets.How to Get Rid of Carpet Beetles?
Carpet beetles can cause significant damage if left unchecked. Eliminating them requires a combination of cleaning, treatment, and prevention.Vacuum ThoroughlyRegular vacuuming is your first line of defense. Focus on carpets, upholstered furniture, baseboards, and cracks where larvae might hide. Use a hose attachment for hard-to-reach areas, and immediately dispose of vacuum bags. Wash Infested FabricsLaunder all affected clothing, bedding, and fabrics in hot water, ensuring a minimum temperature of 130°F to kill eggs and larvae. Drying these items on high heat provides an added layer of protection.Apply InsecticidesInsecticides specifically formulated for carpet beetles can target larvae and adult beetles. Apply to infested areas such as carpets, furniture, and storage spaces, following all product instructions. Seal Entry PointsBlock any kind cracks and openings around windows, doors, and baseboards to prevent future infestations. Making sure your home is well-sealed helps keep carpet beetles from finding their way inside again.How to Prevent Carpet Beetle Infestation?
