Carpet beetles are a common household pest known for damaging various materials, especially upholstery, carpets, and clothing.
Their life cycles range from around 180 to 650 days, depending on the species and environmental conditions.
These insects go through four stages of development: egg, larva, pupa, and adult.
The larval stage is the most destructive as they actively feed on organic materials, including fabrics, lint, and pet hair.
Carpet beetle larva
Adult beetles usually measure between 1/8 to 1/4 inch in length and have various colors and patterns on their wings.
As the larvae grow, they molt and shed their skin, leaving behind telltale signs of infestation.
Different species of carpet beetles might have slightly varying life cycles.
Some might take two to three years to complete their life cycle, while others can have multiple generations within a year.
Preventative measures and proper cleaning can effectively combat carpet beetle infestations and protect valuable possessions.
Carpet Beetle Life Cycle
Carpet beetle females lay around 50-100 eggs near food sources.
The eggs are small and hatch in about two weeks, depending on the environment’s temperature.
The higher the temperature, the shorter the hatching time.
After the eggs hatch, the carpet beetle larvae emerge. These larvae feed on high protein foods, usually animal-based.
Though, they can consume plant material as well. The larvae stage is the most damaging, as they feed on materials in your home.
Key Features of Larvae:
- Feed on high protein foods
- Can consume plant material
- Most damaging stage
As the larvae mature, they enter the pupal stage. During this stage, they undergo a transformation into adult carpet beetles.
The duration of the pupal stage depends on factors such as temperature and species.
When the pupa stage is complete, new adult carpet beetles emerge.
The complete life cycle of carpet beetles takes four to 12 months, depending on temperature and species.
In warmer conditions, their life cycle is shorter, and there can be three to four generations per year.
Characteristics of Adult Carpet Beetles:
- Round shape
- 2 to 3.5 mm long
- Black with yellow and white mottling of scales on the back, and thick yellow scales on the legs
Comparison between different stages:
|2 weeks (approximately)
|Hatch near food sources
|Varies based on species
|Feed on high protein foods, cause damage
|Varies based on species
|Transformation stage, duration depends on factors
|4 to 12 months
|Complete life cycle, multiple generations per year
Recognizing Carpet Beetles
There are several common species of carpet beetles, including:
- Black carpet beetle: larger in size and considered more destructive than other species
- Varied carpet beetle: known for its distinctive, mottled appearance
- Furniture carpet beetle: commonly found infesting upholstered furniture
Black Carpet Beetle
The black carpet beetle is usually 3-7 mm in length, with a shiny, black, oval-shaped body.
It is known to be more destructive than other species due to its longer larval stage and preference for a wider range of materials.
Black Carpet Beetle
Varied Carpet Beetle
The varied carpet beetle, or Anthrenus verbasci, is smaller than the black carpet beetle, measuring around 2-3 mm in length.
It has a distinctive mottled appearance, with white, brown, and yellow scales on their upper body.
Varied Carpet Beetle
The larval stage is tear-drop shaped and covered with light brown hairs. They primarily feed as scavengers on organic debris.
Furniture Carpet Beetle
The furniture carpet beetle has a similar size and shape as the varied carpet beetle but can be distinguished by the yellow, white, and black scales on its body.
This species is commonly found in upholstered furniture.
|Black Carpet Beetle
|Varied Carpet Beetle
|Furniture Carpet Beetle
|Mottled White, Brown, and Yellow
|Yellow, White, and Black
|Wide range of materials
Causes of Infestation
Carpet beetle infestations indoors typically occur when beetles or their larvae enter your home through open windows or doors.
These pests are attracted to:
- Animal materials such as wool, fur, hair, feathers, and silk
- Soiled cotton, linen, and synthetic fibers
- Dead insects, book bindings, glue, leather, and bones
Some common indoor hiding spots for carpet beetles include closets, behind furniture, and along baseboards.
For example, larvae may feed on lint, pet hair, food crumbs, or other organic debris that accumulate in these areas.
Indoor Infestation Causes:
- Open windows or doors
- Presence of animal materials
- Accumulated organic debris
During the summer, carpet beetles can also infest outdoor spaces like nests and gardens. The insects often lay their eggs near food sources, such as:
- Nests of birds or rodents
- Flowers that produce pollen
- Light sources at night
Outdoors, carpet beetles can become a pest to plants, feeding on pollen and occasionally causing damage to garden plants.
Varied Carpet Beetles
Outdoor Infestation Causes:
- Warm weather in summer
- Proximity to nests or gardens
- Access to light sources at night
|Open windows & doors
|Warm summer weather
|Presence of animal materials
|Proximity to nests
|Accumulated organic debris
|Access to light sources at night
Damage and Problems Associated with Carpet Beetles
Carpet beetle larvae are known to cause significant damage to various materials, including textiles and animal products.
Some common items affected by these pests are:
- Wool clothing
- Natural fibers, such as silk and leather
- Animal products like fur and feathers
- Book bindings and furniture
For example, a wool sweater might become riddled with holes due to carpet beetle larvae feeding on the natural fibers.
These pests are also capable of damaging synthetic fibers, but usually only when the items are soiled or contain traces of organic material to attract them.
Aside from material damage, carpet beetles can contribute to allergy issues.
The tiny hairs that cover the larvae can cause skin irritation and allergic reactions in some individuals.
Symptoms may include redness, itching, or rashes on the skin.
To minimize the risk of allergies from carpet beetles, preventive measures such as regular vacuuming and inspection of susceptible areas can be helpful.
In summary, while dermestids like carpet beetles can cause material damage to various items and contribute to allergy issues, there are ways to manage and minimize these risks.
Keeping the home clean and regularly inspecting susceptible items can help prevent issues associated with carpet beetles.

Preventing and Managing Infestations
Cleaning and Sanitation
Regular cleaning is crucial to preventing carpet beetle infestations.
Vacuum thoroughly, especially in corners and under furniture, to eliminate larvae and eggs.
For example, steam cleaning can effectively kill the larvae and sanitize the infested areas.
Some essential tips for cleaning and sanitation:
- Regular vacuuming
- Steam cleaning
Insecticides and Treatments
Using registered insecticides may help manage carpet beetle infestations.
Boric acid is a popular option, as it can be sprinkled on carpets, furniture, and other infested areas.
However, improper application can be hazardous, and treatments may have varying effectiveness.
Other methods are available to manage carpet beetle infestations without chemicals.
Vinegar, when mixed with an equal part of water, can be lightly sprayed on infested items to kill larvae.
Some alternative solutions:
- Temperature control (heat treatments)
- Vinegar spray
If the infestation persists despite efforts, consider hiring a professional pest management company. They have the expertise and tools necessary to effectively handle carpet beetle infestations.
Carpet Beetle Larva
Significance for Ecology and Distribution
Carpet beetles, particularly the black carpet beetle, can cause significant damage to household products.
These insects are of ecological importance as they help break down organic matter. Their distribution is notable as they are found worldwide.
Adult beetles have a role to play too. They mainly feed on pollen and nectar from plants, thus aiding in pollination.
A common location where adult beetles can be found is on crape myrtle plants.
Mating is an important aspect of carpet beetles’ life cycle. After mating, female beetles lay their eggs in areas with sufficient food supply for their larvae.
This ensures a new generation of beetles continues the species’ ecological role.
Here is a comparison table of features between two common species of carpet beetles:
|Black Carpet Beetle
|Varied Carpet Beetle
|Black or dark brown
|Mottled brown and cream
|Households, lint, dead insects
|Households, lint, pet hair
Some interesting characteristics of carpet beetles include:
- Ability to cause damage to household products
- Adults’ active role in pollination
- Worldwide distribution
- Larvae’s scavenging abilities in breaking down organic matter
In conclusion, understanding the life cycle of carpet beetles, from egg to adult, is crucial for managing these common household pests.
Recognizing the distinct characteristics of different species, such as the Black, Varied, and Furniture carpet beetles, aids in effective identification and control.
The article has highlighted the causes of infestations, the damage they inflict, and various management strategies, emphasizing the significance of regular cleaning, targeted treatments, and professional assistance when necessary.
Additionally, the ecological importance and worldwide distribution of carpet beetles have been explored.

Letter 1 – Buffalo Carpet Beetle
Location: New Jersey, USA
December 12, 2010 12:32 am
Can you tell me about this bug found in my house? It is very small, about the size of a sesame seed.
This is a Buffalo Carpet Beetle or Common Carpet Beetle, Anthrenus scrophulariae. Carpet Beetles in the genus Anthrenus are “An abundant household ‘stored product pest.’ In nature they inhabit the abandoned nests of birds and mammals, as well as old wasp nests where the larvae scavenge on accumulated fur, feathers, skin flakes, and dead insects” according to BugGuide.
BugGuide gives this advice for Carpet Beetle control: “Controlling carpet beetles can be achieved by keeping your home free of accumulated hair and dust (dust is mostly shed skin flakes of people and pets), discarding infested items and properly storing vulnerable items.
Store dry foods (including dry pet food) in glass or metal containers with tight-fitting lids. Store woolens, furs, silks in a cedar chest. Forget mothballs and moth crystals. They are ineffective and carcinogenic respectively.”

Found this crawling on my pillow last night. The weather here has been warm and cold almost spring but not yet. Think this critter got confused.
This is a Buffalo Carpet Beetle, Anthrenus scrophulariae, one of the most colorful of the household pests in the family Dermestidae. Larvae of Carpet Beetles feed on a wide variety of organic items in the home, including stored foods and textiles composed or organic materials like leather and wool.
According to BugGuide: “Adults copulate and feed on the blossoms of white flowers; the females require nectar and pollen to stimulate oviposition, which usually limits indoor infestations.
Mated and fed females fly into houses or carried in on flowers. Once inside, or in an animal burrow or nest, the female lays eggs and dies. Larvae feed until the end of the warm season, when most pupate and the remainder overwinter.”
Letter 3 – Carpet Beetle Larva
would appreciate info on this bug
I’ve been finding about 4 of these critters a week under my bed for a few years. On a couple of occasions, I’ve found them where I work, so they may be parasitic, and living off of me. The pictures show one 3 mm long by 1.5 mm wide, which is as big as they get.
On three very rare occasions I’ve seen one (of a different sex, I imagine) which is twice as long, less round, and more conical, and with long hairs on its tail. All are brown on top, tan on the bottom, with 2 rows of legs, about 20 legs each.
They are very inactive, and quite robust, being able to survive 24 hours in the freezer, or 2 weeks without food. I’ve made a short movie that shows one using it’s many legs to flip over, and run away. It’s in Real Player format, and can be found on the web at http://www.angelfire.com/scary/redcom/bug.rm
Here are four pictures, next to a penny, with the last picture being of the rarer sex. Flipped over so can see legs underneath. Diff sex, looks smaller coz of camera distance, but is twice as long, conical, and with hairs on tail
Thx in advance for your help.
Only one of your photos arrived, actually four copies of the same image. Based more on your description than your blurry photo, it seems you have Carpet Beetle larvae

what is this bug?
1/4″ in length. many legs on each side. somewhat hairy. has a wormlike head that wiggles around, the back end almost looks like wings creeping out from under a jacket. the jacket is light oolored belt around the midsection and the ends are darker. the tummy of the bug is all light colored.
they had no visible antenna or tail (through a magnifying glass)…… 4 of these were on one sons wall in his bedroom. one more was sighted in an upstairs bedroom. they are very slow moving, in a slow wiggle sideways. when dropped in the carpet, they burrow down into it. help. thanks.
You have a Carpet Beetle Larva, one of the Dermestid Beetles which eat wool and other natural fibers as well as doing major damage to museum collections.
Letter 5 – Carpet Beetle Larva
Recently, i noticed some tiny bugs on a clean towel that i picked up from our bedroom wardrobe. After that, i examined all the clothes in our bedroom closet and discovered quite a lot of these bugs, most of them on clothes made from wool or cotton.
It was almost impossible to get rid of them because they were hardly seen, so we took all of our clothes to the laundry. Their size is from 2 mm up to 7 mm that is 1/12″ up to 1/4″ inches (so i guess that the guy on the photo must be their… king).
Later on that day, i discovered their… kingdom. A knitted carpet of wool, carefully stored in the wardrobe closet but not inspected for a long time, was covered all over of these bugs, so much that you couldn’t make out the drawing on it.
Can you please tell me, what’s that bug and what caused the presence of it? Finally, is there a way to prevent this situation to the future?
Thanks for your help.
There is a reason your insect was discovered in the carpet. It is the larval form of a Carpet Beetle, Family Dermestidae. By now you must realize that they will destroy a fine wool rug that is being stored.
They will also infest wool clothing, get into suede and leather, ande they are responsible for horrific damage to museum collections.
Letter 6 – Carpet Beetle Larva
Carpet beetle larva from MN
Hello Daniel and Lisa.
Thanks to your site, which I visit almost daily now, I was able to identify a carpet beetle larva when I first saw it last year crawling up the wall in my room. Now I found another one this year in the same place and time, and now I have a better camera for getting a decent picture of it.
I noticed that you made it the Bug of the Month for April, and the picture you have up there is a little blurry, so I thought you might like some clearer images. I’m still not sure of the species of this one though. I live in Brooklyn Park, Minnesota.
Thanks for providing us with a sharper and more current image of a Carpet Beetle Larva. We scoured the archives for the one we originally posted in the Bug of the Month for April 2008 posting.
Letter 7 – Carpet Beetles
can you help me identify these bugs?
I found these bugs in one of our storage units. Can you tell me what they are? I attached a photo. thank you!
You have an Anthrenus Carpet Beetle infestation. Adult Carpet Beetles feed on pollen, and are usually noticed by homemakers when the congregate on windowsills in an attempt to reach the outside world. The larval form is the phase that does the damage.
These fuzzy larvae feed on wool, feathers, fur and other animal products. They can do major damage in museum collections. Adult Carpet Beetles reach a length of about 4 mm. Your beetles look like Anthrenus verbasci, the Varied Carpet Beetle.

What is its common & scientific nam
These bugs were found in Hamilton Co., OH 2nd last
week of April, 2008 in my garden on Sweet Woodruff & are very tiny. Can you please ID. Thank you.
Mary Jo White
Hi Mary Jo,
Your photo shows two species of Carpet Beetles in their typical adult environment. Many homemakers find adult Carpet Beetles in the spring on the windowsills of their homes. The larvae feed on natural fibers like wool carpet, pet hair and other similar items found in the home. Adults feed on pollen.
The upper beetles (please note that we rotated your photo for our website) are of the Buffalo Carpet Beetle, Anthrenus scrophulariae, one of the showier members of the genus because of the red coloration.
The smaller, drabber beetle is also in the genus Anthrenus, but we are not certain of the species. You can check possibilities on BugGuide. The Carpet Beetle was our featured Bug of the Month for April 2008.

I found two bugs near the crown molding on the floor of my apartment. I’ve attached pictures of the one. It is black on top with a beige sort of stripe, with a few white dots on it. The other bug I found had part of the beige stripe, but it was not as distinct.
Thanks, Phils Fan
Dear Phils Fan,
This is a Carpet Beetle, Anthrenus pimpinellae. We identified it on BugGuide where it is stated that it has a cosmopolitan distribution. The genus page on BugGuide states: “Season Adults mainly occurr in spring, but may be found the whole year round in heated rooms.
Food Adults feed pollen on flowers; larvae feed keratine and chitine, and may cause considerable damage on wool, fur, feathers, and natural history collections.“

February 18, 2010
I’m not a bug enthusiast by any means so I have no idea what this bug is. It seems to look like a minute lady bug-like insect. Colors seem speckled with gray and dark red/brown with wings. Tentacles too.
It must have fallen on to me at some point during the day as it fell out of my hair when I rinsed my face. It fell into the sink. I have no idea how it got on to me. That day I was painting indoors and had a hat on most of the day except when I ran out, but was painting a very old dirty room, maybe it was in there.
this was 2 days ago.
It was below freezing.
This couldn’t carry a disease right?
Thanks for your help
This is a Carpet Beetle in the genus Anthrenus, a common household insect. It does not carry disease, but they may cause considerable damage to wool, fur, feathers and natural history collections.

Sorry I used wrong form. I found this bug in my bedroom. I have a live one in a box. He is about 1/4 inch long with little hairs on his back. 3 legs each side, to the front of his body. very dark and pale cream stripes. Lots of dicarded shell casings but he does not look like a bedbug. his body is quite rounded. Moves quite slowly in a concertina like movement.
I am being bitten and was looking for bedbugs. I have cleaned and smoked the room. Would be gratefull for your advise as I cannot find this little darling anywhere on the internet.
I should mention that we have just replaced our roof andall the stuff out of the loft came downstairs and we have been overseas in the last 6 months
Your sketch of this Carpet Beetle Larva is much better than your photograph. Carpet Beetles are common household pests, but we do not believe it is responsible for the bites you are getting.
Many thanks for your help. Have fumed and cleaned the room and will keep a vigilant watch for more offspring. Seen the doc and he says they are definately bites. I think they are scabies but he is not convinced as they are not between my fingers and are generally in groups of three.
No other family member is affected. They are quite nasty and it has taken antibiotics in addition to lyclear cream to calm them down. Still the mystery remains. I will try to make a donation to your organisation via paypal Many Thanks Ann

We have been away from the office for a week and your email is the first we read. Your subject line attracted our attention. This is a common household pest known as a Carpet Beetle Larva.
They will eat many organic substances in the home and they have adapted well to cohabitation with humans, though humans do not benefit from the relationship. Adult Carpet Beetles feed on pollen, so they fly outside to mate and then return to the home to lay eggs. Carpet Beetles in the imago stage are mostly observed by homemakers dying in windows.

These pinhead-sized (or smaller) winged beetles appear in the spring inside my house. They are attracted to the windows and to light-colored fabric. They are slow-moving and nonevasive, and so they are easy to kill. They are appearing now, when temperatures are in the 70’s.
My guess is they are in a foodstuff of some kind in the house. They do not appear in overwhelming numbers, but they come every year consistently. I do not see them at other times of the year.
