Do Carpet Beetles Survive Freezing Temperatures?

The carpet beetles are not able to survive in freezing temperatures. The insects are cold-blooded, so their bodies can’t regulate internal temperatures efficiently.

The body temperature of carpet beetles can be raised or lowered by exterior sources.

If the outside temperature is 50 degrees Fahrenheit (10 degrees Celsius), the beetle’s body temperature is the same as the outside temperature.

If carpet beetles are put in containers with freezing temperatures, they will end their lives.

Freezing Carpet Beetles

According to Pest industry experts, freezing carpet beetles is one way of killing them. The proper application should be followed to eliminate these cold-blooded pests.

How to Freeze

  • Wrap the infected items tightly in plastic bags.
  • The bags should be placed in a chest freezer.
  • It is recommended to set the freezer’s temperature to at least 0 degrees Fahrenheit.
  • Before removing the bags from the freezer, you should wait at least seven days.

The death of carpet beetles can be accelerated by setting the freezer to a temperature that is too warm.

Setting the temperature to -20 degrees Fahrenheit (-28.89 degrees Celsius) can kill the insects within three days.

Make sure to thaw the freezer to make sure the device works well.

What do Carpet Beetles Look Like?

If you understand the appearance of the carpet beetle, you’ll be able to tell if there’s an outbreak.

An adult carpet beetle has an oval shape with a length that can be as long as 1/16th of an inch.

Black, brown, white, yellow, and orange are some of the colors that can be different.

There are mottled patterns on the insect’s body, making it distinguishable from a reasonable distance.

Signs of a Carpet Beetle Infestation

The carpet beetles are difficult to spot because they are about 1/6-inch long. These pests like to live in dark places, such as under the floorboards.

The pest’s name is because they like to hide between the carpet fibers. Before the situation gets worse, it is important to know the signs of a potential carpet beetle outbreak.

Fabric Damage

Furs, feathers, wool, and dead insects are some of the animal products that carpet beetles like to feast on. Carpets made from synthetic and natural fibers are favorites of pests.

Since eating synthetic substances won’t satisfy their hunger, carpet beetles will eat more than they intended, leaving behind holes and thinner areas.

There are huddles where carpet beetles like to feed. If the holes on the damaged fabrics are clustered instead of being spread out, it’s a sign of a carpet beetle problem.


There is a carpet beetle that leaves droppings that are about the size of a grain of salt. The droppings will be easy to see because they are concentrated in one spot.

Shed Skins

As they grow they lose their skins. The shed skin is brown. Like the excrements, the larvae will concentrate in one area.

At What Season Do Carpet Beetles Come Out?

Carpet beetles mature in spring or summer. Females can lay hundreds of eggs, which will hatch in about a month.

Within nine months to two years, the young will develop into adulthood. For a long time, the larvae can survive without food or water.

According to a 2001 study by the New Mexico State University, mature beetles will only live for a few weeks.

Is It Possible That Carpet Beetles Go Away on Their Own?

If there is still food for the beetles, they will not move from one spot to another. Special deterrents should be used to make sure the insects won’t come back.

The beetles cannot get into the fabrics if clothes are sealed in plastic bags. The insects can feast on fabrics that have been sealed with carpet beetles.

Are Carpet Beetles Harmful?

The carpet beetles are not poisonous and they don’t bite people. Damage to fabric-type objects in homes can be caused by insects.

The beetles can eat food when they get into the pantry, and the bacteria left behind can cause food to be contaminated.

How Long Will It Take to Get Rid of Carpet Beetles?

The method used to eliminate carpet beetles affects the time it takes. The insects can be killed by using harsh chemical fabric cleaners.

Spot-cleaning using commercial pesticides can be effective at preventing carpet beetle invasions.

Some of the products have components that can harm the environment. Using harsh chemicals can take longer than using non-chemical carpet beetle control practices.

Is It Possible That Vacuuming Will Get Rid of Carpet Beetles?

It is possible to eliminate carpet beetles with a vacuum, but not complete control. Adult and young carpet beetles, as well as their eggs, can be sucked up by vacuum cleaners.

Many vacuums can’t suck these creatures living in tight spaces like the cracks in walls or the crevices between floorboards.

Homeowners can find the problem quickly if they rely on their vacuum cleaners.

How Can I Get Rid of Carpet Beetles Permanently?

One way to eliminate carpet beetles permanently is by freezing. The following techniques are used to make sure these pests don’t breed, thrive, or return.


Store-bought insect killers can be used to kill carpet beetles permanently. Bifenthrin, deltamethrin, and cyfluthrin are ingredients in products.

A study shows that dichlorobenzene, the main ingredient in many insect repellants, can help eliminate carpet beetles.

Boric Acid

When poured on carpet beetles, Boric acid can kill them, even though it is hazardous to humans. Sprinkling a small amount on an adult or young pests can help eliminate them.

It is possible to spread the substance across the areas to discourage the beetles from eating fabrics.


In eliminating adult carpet beetles, insect foggers are effective. It is a fast and easy solution, but can’t kill eggs.

Diatomaceous Earth

An organic product called diatomaceous earth can kill carpet beetles in a matter of minutes. Boric acid can be spread across surfaces like carpet fibers and clothes drawers.

The risks of harm to humans and pets will be reduced by using food-grade diatomaceous earth while wearing a mask or respirator.

Fix Wall Cracks

Like wall cracks, carpet beetles like to live in tight, dark areas. It’s possible to prevent insects from living in establishments by fixing these ruptures.

The use of an injection system to seal cracks in concrete walls is one way to deal with this concern.

Tapes can be put over small cracks for a short time, although the tape can look unattractive.

Professional Exterminators

Pest control experts are excellent at removing carpet beetles permanently.

Some companies charge customers over US$100 per request for specialized services. Depending on the severity of the problem, the costs can vary greatly.


It is possible to kill carpet beetles with freezing fabrics. The proper freezing procedure will ensure that the insects will no longer be found on cotton, wool, and feathers.

It takes a few days to complete the process of freezing carpets to kill the beetles.

If you take those items out of the freezer quickly, the pests will continue to feast on them. There are many other ways to kill these pests, including freezing insect-infested items.
