What Is a Black Beetle?
Black carpet beetles (Attagenus unicolor) are common and destructive household pests. When you see these little black beetles in your home, your furs, feathers, fibers, and grain products are at risk. They’ll also chew on your wool carpet and take up housekeeping in your cereal box.
What Do Black Carpet Beetles Look Like?
An adult black carpet beetle is between 1/8 to 3/16 inch (0.32 to 0.48 cm) long, with a shiny dark-brown to black oval body. Black carpet beetle larvae look like armored segmented carrots with bristly hairs. They’re rusty reddish-brown with a tuft of spiky hairs protruding from their bottom.
Are Black Beetles Harmful?
These tiny black beetles don’t bite humans at any stage in their life cycle. And by the time you see them in your home, they’re no longer eating your clothing or furniture. The real damage comes from the baby black beetles.
While they’re still growing larvae, baby black carpet beetles can eat unsightly holes in clothing and furniture. And because they hide in dark enclosed places, they can go unseen until they’ve done significant damage and infested your entire home.
How Long Do Black Beetles Live?
Black carpet beetle eggs hatch 9 to 16 days after laying. The black carpet beetle spends 166 to 310 days in this larval stage, eating carpets, cushions, and sweat stains until it grows to about 1/4 inch (0.64 cm) long. Then it forms a hard pupa (cocoon).
Adult beetles emerge between eight and 14 days after pupation, but they only live a few weeks. They may eat a little bit of flower pollen or an occasional petal, but many don’t eat at all. Their only thought is to find a mate and hatch a new generation.
What Do Black Beetles Eat?
Black carpet beetle larvae feed on natural fibers and grains. Because they’re scavengers who eat dander and animal debris, baby black carpet beetles will also chew on synthetic fibers with oil, sweat, or food stains.
Types of Black Beetles
When exterminators get calls about flying black beetle bugs, black carpet beetles are usually the problem. But there are other types that may bring homeowners grief. If you’re wondering what the black beetles are in your house, we can help you distinguish between a black carpet beetle, boatswimmer, weevil, or other unwanted beetle guests.
What Causes Big Black Beetles in Home?
Black ground beetles (Family Carabidae) want only to stay in your yard and eat garden pests. But when their pest-hunting accidentally leads them into houses, they often get mistaken for giant cockroaches. A black ground beetle is four to eight times larger than a black carpet beetle, and black ground beetle larvae live in soil, not carpets.
To keep black ground beetles out, caulk up any gaps in your window frames. Move leaf and rubbish piles as far away from your house as you can. They’d rather be outside where they can lay their eggs in the dirt. Give ground beetles distance, and they’ll keep theirs.
What Attracts Black Beetles?
Black beetles, like other insects, are attracted to food and shelter. If they discover things they can eat in your home or places to lay their eggs, they’ll stay. Learn what black beetles want, and you’ll know what you must protect from black beetles.
How Do Black Beetles Get in the House?
In springtime, adult black carpet beetles may fly into your home through a doorway or open window. Once there, the female black carpet beetle may lay eggs in food sources like your carpet or couch. Or she may wander to a dark and secluded area where her eggs can safely brood until hatching.
If you bring a box of old woolens or fabric into your house from the shed, you may introduce black carpet beetles, as they’ve also been known to enter homes in bags of dog food or other stored products.
How To Get Rid of Black Beetle Infestation? Step by Step Instructions
If you’ve just discovered damage to your carpet or your stored clothing, you may be dealing with black carpet beetles, and you want to know how to get rid of them quickly. Here’s a step-by-step guide to handling your black carpet beetle problem.
1. Locate All Black Beetle-Infested Items
Examine the seams, folds, and creases of your stored items. Look closely for any dried larva skin sheds or tiny wiggling worms buried in the fabric. Check the edges of your carpeting for bare spots or signs of larva-nibbling. Pay close attention to woolen or fur items.
2. Check Your Home for Black Beetle Infestation
Check furniture cushions and upholstery. Look around floor vents and ducts, especially if they’re covered in lint or pet hair. Check your pantry, especially your grain-based products and your pet’s food dish.
3. Vacuum Your Home To Remove Black Beetles
Vacuum your apartment thoroughly, paying close attention to upholstered furniture and carpets. Make sure you get corners and baseboards, as these are favorite hiding places for carpet beetles and other insect pests. Also, vacuum every nook and cranny of your closets and clothing storage areas.
4. Clean or Discard Carpet Beetle Infected Items
Separate any clothing or items that may be carrying black carpet beetle larvae into a keep and a discard pile. Bag the discard items, and get them out of your house as soon as you can. This will help stop the further spread of the beetles. Dry-cleaning or running your items through a hot dryer will kill any remaining eggs and larvae.
How To Get Rid of Black Beetles in Some Specific Places?
There are many different black beetle pests and black beetle bugs. Here are some other places you might find black beetles and some quick ways to get rid of them.
How To Get Rid of Black Beetle in House (Apartment)?
After you finish following the steps above, you need to keep your stored clothing safely sealed away. You’ll need to vacuum your carpets and your upholstery regularly. The best way to win the war against black beetles is to avoid playing it.
How To Get Rid of Black Beetles in Swimming Pool?
If you see small black beetles in your swimming pool, you have either water boatmen or backswimmers. The water boatman (Corixa punctata) ranges between 1/5 and 1/2 inches (0.51 and 1.27 cm) long and has long hind legs that help it swim.
Backswimmers (Family Notonectidae) look like water boatmen but swim on their backs. Water boatmen eat algae, and backswimmers eat water boatmen. Be careful handling backswimmers, as they have a sharp beak and can deliver a painful bite.
To get rid of algae – and with it, the black beetles in your pool – do the following steps:
1. Give your pool bi-weekly shock chlorination.
2. Add chlorine until your water’s chlorine level rises from 1 to 3 ppm to between 6 and 13 ppm.
3. Do this at night, and don’t swim until the chlorine is back to 1-3 ppm.

If you opened your flour canister and found it crawling with tiny black beetles, you’re most likely dealing with wheat weevils (Sitophilus granarius), which are about half the size of a black carpet beetle.

How To Get Rid of Black Beetles in Garage?

How To Get Rid of Black Beetles in Garden?
When you see a big black beetle crawling around your flowers, don’t stomp on it! Black ground beetle larvae eat grubs and harmful parasites as they burrow through the soil. Adult black ground beetles eat cutworms, asparagus beetles, cabbage worms, and slugs.
Best Chemicals for Black Beetles
For a severe black carpet beetle infestation, insecticides may be necessary. But while insecticides will help get rid of bugs like black carpet beetles, they won’t solve the problem unless you also take other steps.
If at all possible, avoid spraying insecticides in pantries or near food storage. These areas are prone to bug infestations, and spraying is tempting. But the risk of exposing yourself and your family to unhealthy levels of pesticides is too high.
Food grade diatomaceous earth like the Harris Food Grade Diatomaceous Earth Powder is non-toxic to humans (some people even take it as a food supplement!). But its tiny sharp edges kill insects. Powdering your home with diatomaceous earth is a much safer way of controlling beetle infestations.

How To Keep Black Beetles Away?
Dry-clean or launder items before you store them. Keep stored things in tight-fitting plastic bags or sealed containers. You can also store furs and other valuable garments in cold vaults. Ask your local furrier or dry cleaner for more information.
Black carpet beetle larvae eat dust and dander. The less dust and pet hair around your house, the less chance you have of an ongoing black beetle infestation. And because vacuuming sucks up eggs and larvae, black carpet beetles don’t damage regularly vacuumed carpets.
There’s no easy cure for black carpet beetle infestations. Getting rid of beetles will require some work on your part and continuing maintenance. Vacuuming your home thoroughly and regularly and cleaning or getting rid of carpet beetle-infected stuff will ensure that the black carpet beetles don’t come back. Black carpet beetles are a problem, but one you can beat with a bit of effort.
