Do you think you have a carpet beetle infestation? In New Jersey, we have two species of carpet beetle: the black carpet beetle and the varied carpet beetle. All carpet beetles can be found throughout the continental United States but they are most common in the Northeastern region of the country, especially near the coast. Let's take a look at how you can figure out whether or not the insects in your New Jersey home are carpet beetles and discuss some other important facts about these destructive pests.

Black carpet beetles, referred to scientifically as Attagenus unicolor, are one color: black. Varied carpet beetles, Anthrenus verbasci, are a mixture of tan, black, brown and white. These insects have 6 legs, two antennae and two sets of wings that stack on their backs and are divided in the middle. Black and varied carpet beetles are around 3 to 5 mm in length and oval-shaped.


You may find it surprising but adult carpet beetles don't eat carpets. They feed on nectar and pollen. It is the larvae of carpet beetles that eat your carpets. They'll also eat fur, wool, hair, furniture, clothing made from natural fibers, and lint. Inside your walls, they'll eat dead insects, rodent hairs and bird feathers. Their dietary preferences make them a threat to the belongings inside your home.

Life Cycle

There are four stages of life for a carpet beetle:

  • Egg: A female carpet beetle can lay as many as 100 eggs. These eggs are only about .35 to .75 mm in length. They are not much more than specks but they are still visible to the naked eye. You can find these eggs in cracks and crevices or near food sources for the larval stage.
  • Larvae: The larvae of carpet beetles are about twice as long as the beetles, which can be from 6 to 12 mm long. In this stage, they are fuzzy-looking caterpillars, not beetles.  
  • Pupa: In this intermediate stage, carpet beetle larvae are white. They stay in this state for two or three weeks. Pupation often happens near a food source so you probably won't find pupa attached to a piece of clothing or blanket that was eaten by larvae. They'll usually move off the food source to enter this stage.
  • Adult: An adult carpet beetle only lives about two months and this is usually in the spring. This is the six-legged, beetle stage.

How do you get carpet beetle larvae in your house?

In the adult stage, these beetles fly right into your home through an open door or window and immediately look for larval food sources on which to lay their eggs. When the eggs hatch, the larvae begin to feed. Adult carpet beetles are great fliers and they are attracted to light. When you come into your home at night, this is often when one of these insects enters. Adult beetles can also be brought in on flowers because they feed on nectar and pollen.

How do you get rid of carpet beetles?

You can apply natural products around your home that will act as a desiccant and dry larvae and kill them, but this is not an easy task and there are many ways it can fail. Pest control products are much more effective at eliminating a carpet beetle infestation, but these are best applied by a licensed and certified pest control professional. Improper application of pest control products can be very harmful to you and everyone living in your home.

Can carpet beetles live in couches?

Yes. If your furniture has natural fibers or a mixture of natural and synthetic fibers, carpet beetle larvae can live in your couches. Adult carpet beetles may hide in your furniture no matter what it is made of.
