​What do Carpet Beetles Look Like?    

Like with most insect species, carpet beetles aren’t just one type. Here are the different kinds of carpet devourers you can find in the average household, their specific behaviour, diet, habits and of course - reproduction cycle and general lifespan:

Carpet Beetle Types:

​The three widespread species are:

Furniture Carpet Beetles - Anthrenus flavipes (LeConte)

​This type of bug is small in size - about 0.3-0.5cm. It has a round light brown shell, which is speckled with black and white spots, and owns 8 legs​​​​. The furniture carpet beetle highly resembles the varied one, which is why many people get them mixed up.

​Varied Carpet Beetles - Anthrenus verbasci

​The varied carpet beetle is only 0.25cm, making it the smallest example of the carpet beetle family. It has a slightly rounded shell in a blackish colour with white splatters. The varied carpet beetle has only 6 legs.

​Black Carpet beetles - Attagenus unicolor

This type of carpet beetle is huge in size compared to the rest of the family members - it can reach about 1 cm in length. It also has a specific shape, which makes it easy to distinguish from the rest of its cousin carpet beetles. As the name states, its shell is a solid black colour. It has 6 legs and 2 highly visible antennas.

Carpet Beetle Behaviour, Diet, and Habits

​As the name suggests, carpet beetles mainly munch on wool carpets.

“Nowadays, infestations have dropped a lot, due to the fact that most rugs are made from synthetic fibres, which the bugs can’t eat. In the summer, these insects seem to migrate to cooler areas,” ​says Alexander Crawley, a professional pest exterminator at Fantastic Pest Control (Australia).
“These pesky critters can occupate your both entire house or just a single rug. Baby carpet beetles are fond of animal hair, dead insects, and even feathers. Adult bugs tend to enjoy a wealthy dinner before laying any eggs. These insects, also know as Coleoptera, in the superorder of Endopterygota, are known to hunt and grow in birds’ nests, pet’s fur, and also carpets, are often attracted to storage containers made from natural materials.” added the expert from Fantastic Pest Control, “Some get a bit more creative and could even attend an insect museum to eat the specimens.”

Carpet Beetles Reproduction and Lifespan

​This particular species is Endopterygota (also known as Holometabola), which means it experiences absolute metamorphosis  - from egg to larvae, then to pupae and finally, adulthood.

Black and varied carpet beetles give birth to just one generation, while other species can produce multiple. Lifespan varies a lot too. Some carpet beetles live up to three months while others can prosper for years.

​Usually, carpet beetles mate during the summer, lay eggs and die right after that. Their lifespan depends on the amount of food it gets while in the larvae stage.

How Do You Know if You Have Carpet Beetles?

​If you suspect that you are a victim of a carpet beetle attack, but still aren’t 100% sure, here are 5 sure signs of upcoming infestations you should look out for:

  • 1
    Adult beetles near windows. An interesting fact is that adult carpet beetles don’t do much damage - their larvae are the ones to blame. Carpet beetles mainly eat pollen and can be spotted in the warmer months around your windows, desperately trying to get out. If you discover a tiny beetle near that area in the spring or summer months, without a shadow of a doubt, you have a carpet beetle infestation.  
  • 2
    Concentrated damage. As we discussed earlier, fully-grown carpet beetles won’t do much harm. The real enemy is their offsprings. Larvae tend to feed in dark corners or under heavy furniture, like your living room sofa, for example. Unlike other types of insects that consume organic materials, the moth for instance, carpet beetle larvae eat in concentrated areas. So, if one day you find your favourite shirt, looking like swiss cheese, you probably have a carpet beetle infestation happening right in your closet.
  • 3
    Left-behind larvae skin. Carpet beetle larvae change their skin several times during their nine-month lifecycle. This process is called moulting. Look around your home for signs bugs shedding. Inspect your carpet, the bottom of the wardrobe, or underneath your sofa. If you spot a pile of furry shed skin, congratulations - you are a proud owner of a carpet beetle colony.  
  • 4
    Shy baby beetles coming out to play. Carpet beetle larvae are generally on the shy side when it comes to behaviour, which makes them hard to spot. If you want to lure them out, close the curtains or shut your blinds during the day. Before you know it, you’ll see a small army of beetle babies, marching on the walls or around the dark corners of your property.
  • 5
    Faecal pallets. Like every other living thing, carpet beetles poop. Their droppings are brown to black in colour just like our pets and about the size of a grind of sand. You can find them scattered throughout areas, where carpet beetles tend to feed most often - around the bottom of your closet, on your favourite sweater, or on the floor.

How Do You Get Carpet Beetles And Where To Find Them?

​Carpet beetles are not the brightest representative of the Coleoptera family and that’s why they won’t have much trouble while moving into your home undetected. These evil masterminds are known to travel by plant, meaning you can invite them to your house by simply bringing a rose pot to your home.

They also like to use animals as a way to migrate, so don’t be surprised to hear that your cat or dog may have brought an infestation inside. Carpet beetles can enter your property through chimneys, your plumbing system, vents, and even electrical conduits, too. In other words, this sort of insect has a wide range of options, in which it can invade your home, so it's important to maintain the cleanliness of the ​house if you want to keep these carpet beetles at bay.

How Can You Prevent a Carpet Beetle Infestation?  

​1. Protect infestation prone items:

​Put all clothes made from natural materials, especially those you don’t wear that frequently, in plastic bags.

  • ​Make sure to expose occasionally items, especially those you store in your closet, to direct sunlight. This will make any hidden carpet beetles crawl out.
  • ​Clean your entire home on a regular basis to reduce the chances of an infestation.

2. Check flowers before your bring them to your home.

​Like we said in the article, carpet beetles can get inside your home by hitchhiking on plants. So, before you decide to bring your favourite flowers inside, inspect them carefully for carpet beetles. The same goes for plants you picked from your garden.

3. Make sure to keep doors and windows closed.

​Carpet beetles can fly, so if you leave windows and doors open for an extensive amount of time, you are practically inviting these creatures in. Small holes and damaged walls can also cause problems. Make sure to seal all, and thus prevent bugs from entering.

4. Remove birds’ and animals’ nests from your garden.

​If you happen to have a bird’s nest located on a tree near your house, make sure to remove it as fast as possible. Carpet beetles are most-known to inhabit the homes of birds and other types of animals.

5. Disinfect your rubbish bin on a regular basis.

​After you take out your rubbish, make sure to disinfect the actual bin with antibacterial wipes. Thoroughly clean the container every 6 months with bleach, diluted in water or some other cleaning chemical..

6. Buy synthetic materials.

​Since carpet beetles don’t favour having polyester for dinner, invest in carpets, rugs, sheets, and furniture made from synthetic materials whenever possible.

7. Clean your carpets frequently.

​Vacuum all your carpets and rugs at least once a week. Combine that with regular steam cleaning treatments and eliminate the source of food for larvae - hair, lint, and dead insects. If you don’t have a steam cleaner, you can always hire professionals to treat carpeted areas for you.
