What do carpet beetles eat?

Varied carpet beetle Anthrenus verbasci.

Carpet beetles can be found worldwide. There are a few different species, but they all share some common characteristics. Adult carpet beetles feed on seeds, plants, and flowers. It is their primary food source.

However, larvae are known to feed on animal and plant-based materials. They can digest keratin, which is the protein that makes up hair, feathers, skin, and nails. It means they can feed on various materials, including carpets and clothes.

The life cycle of carpet beetles

The life cycle of carpet beetles

The life cycle of a carpet beetle can vary significantly depending on the species. They will go through four stages: egg, larva, pupa, and adult. Adult carpet beetles typically only live for 3-4 weeks, but they can lay up to 100 eggs.

The eggs hatch within 7-35 days. The larvae will feed on various materials, including carpets, furniture, clothes, and other insects. Once they reach adulthood, the carpet beetles will mate, and the process will start over again.

Carpet Beetle eggs

Carpet beetle eggs are white or cream in color and measure around ¼ to ½ millimeters in length. They take between 7 and 28 days to hatch.

Carpet beetle larvae

Carpet beetle larvae are small, fuzzy, and brown. They turn into pupae: between 2 to 3 weeks. During this time, they are very small and look like a beetle-like state of development. They have dense, sometimes barbed, hairs. Three golden hairs are located on the abdomen.

Can adult carpet beetle have carpet beetle larvae on walls?

Can adult carpet beetle have carpet beetle larvae on walls?

Carpet beetles can climb walls because they have specially adapted bristles on their legs that help them grip surfaces. It allows them to move around rapidly and escape from danger.

Young adult beetles will also search for a way out of the home to feed and mate. The larvae of the final larval molt also climb up flat surfaces in homes, looking for a place to pupate.

Adult carpet beetles can lay eggs anywhere that provides good conditions for larvae development- on materials made from wool, leather, silk, and other fertile grounds.

Interestingly enough, the larvae are responsible for all the feeding damage while the adults feed on nectar and pollen. Once carpet beetles are identified, they are eradicated before too much damage is done.

If you have carpet beetles in your home, there is a good chance that they will re-infest. There are ways to prevent this, however.

Feed in concentrated areas

The larvae of the carpet beetle are the culprit when it comes to damage done to clothing, furniture, and other items in your home. These tiny bugs can be difficult to see as they like to hide in dark corners or under heavy furniture.

They also prefer to feed in concentrated areas rather than randomly across an item. So if you have a favorite sweater with several small holes rather than one big one, the chances are high that carpet beetle larvae and not moths did the damage.

Check for discarded skin

Carpet beetle larvae go through several stages during their lifecycle, and as they grow, they molt their skin. If you see small collections of discarded fur on your carpet or at the bottom of your wardrobe, this is another telltale sign of an infestation.
