Varied carpet beetles are small but intriguing insects with a wide range of characteristics. These beetles are often found in homes, warehouses, and museums, where they can be a pest to stored organic products source. Originally from Europe, Asia, and North Africa, they have made their way to North America around 1850, giving them a virtually worldwide distribution source.
Identifying varied carpet beetles can be a bit tricky, as they are small insects that can easily go unnoticed. Adult beetles measure about 3-5 millimeters in length and have dark-colored or patterned wing covers source. The larvae are similarly sized with a tapered body, featuring alternating light and dark stripes and are covered with tiny hairs that can be puffed up source.
Understanding the characteristics and identification methods for varied carpet beetles can aid in effectively managing them in your home. In the next sections, we will explore their life cycle, feeding habits, and control measures, helping you better protect your belongings and maintain a beetle-free environment.
Varied Carpet Beetle Overview
Identification and Size
The varied carpet beetle (Anthrenus verbasci) is a tiny insect that can wreak havoc on your home textiles. Adults are small, measuring between 3-5 millimeters or about an eighth of an inch in length 1. The larvae are similarly sized and have a tapered body, which makes them easily distinguishable from adult beetles 2.
Color and Shape
Adult varied carpet beetles have dark-colored or patterned wing covers, depending on the species 1. The larvae feature alternating light and dark stripes and are covered in tiny hairs that can puff up if disturbed 1. The shape of adult beetles is rounded, while the larvae have a narrower head end and a wider tail end 3.
Habitat and Distribution
Varied carpet beetles can be found in homes, museums, and warehouses. Their preferred habitats include areas with natural fibers and dry organic materials 4. These little pests are commonly found in carpets, upholstered furniture, and stored textiles. Their distribution is widespread, and they can be found in various regions around the world 5.
In conclusion, the varied carpet beetle is a small but destructive pest that can infest textiles and organic materials in your home. Being aware of their appearance and typical habitats can help you identify and address an infestation before it becomes a major problem.
Life Cycle of Varied Carpet Beetles
Eggs to Pupa
The life cycle of varied carpet beetles begins with the female laying tiny, pale yellow eggs. Over time, these eggs hatch into larvae, which are often tear-drop shaped and covered in light brown hairs. These larvae are known to feed on various organic materials, such as lint, pet hair, and dead insects1. You can generally find them behind furniture or along baseboards in homes, scavenging for food and growing as they consume their surroundings.
As the larvae continue to grow and develop, they undergo multiple molts. Eventually, they enter the pupal stage, during which their exoskeleton hardens and they begin to transition into adults. Depending on the environment and temperature, the duration of this stage can vary, making the overall life cycle last anywhere from several months to a couple of years2.
Pupa to Adults
Once the varied carpet beetle larvae complete the pupal stage, they emerge as fully formed adults. Measuring about 1/10 inch long, these black beetles can have an irregular pattern of white, brown, and dark yellow scales on their wing covers3. However, it’s worth noting that older adults may lose these scales over time, resulting in solid black or brown coloring instead.
These adult beetles go through a circannual cycle, often experiencing three to four generations per year4. The variations in temperature and living conditions can have a significant impact on the length of the life cycle of these insects. As you encounter varied carpet beetles in your home, it’s important to be aware of their life cycle stages in order to effectively manage and prevent infestations.
Feeding Habits and Diet
Varied carpet beetles are known for their ability to feed on a wide range of materials found indoors. They primarily consume materials of animal origin, such as:
- Dead insects: They are attracted to insect carcasses, particularly those of other beetles.
- Hair and fur: They can feed on pet hair, lint, and other types of hair found around your home.
- Fabrics: Beetles are known to infest carpets, upholstery, and clothing, especially if they are made of natural fibers like wool or silk.
- Scales and feathers: These insects are also attracted to materials from birds, such as feathers and shed scales.
If you notice damage to woolens, carpets, and furniture, it could be the work of varied carpet beetles or clothes moths. Regular cleaning and maintaining your home can help reduce the chances of an infestation.
Varied carpet beetles are not limited to indoor environments. They also have some preferences for food sources outdoors. Some common dietary preferences include:
- Pollen and nectar: Adult beetles often feed on pollen from flowers and drink nectar to obtain nutrients.
- Bird nests: They can infest bird nests due to the presence of feathers, fur, and other materials that they can feed on.
- Insect nests or carcasses: Outdoor spaces can harbor various insects and their remains, which can serve as a food source for these beetles.
To minimize the risk of attracting carpet beetles to your property, ensure that your outdoor space is well-maintained and free of any potential food sources. Regularly clean bird nests, dead insects, and other debris to prevent them from infesting your home.
In conclusion, varied carpet beetles have a diverse diet both indoors and outdoors. By understanding their feeding habits and taking preventative measures, you can reduce the likelihood of dealing with these pests in your home.
Infestation and Damage
Signs of Infestation
When looking for signs of a Varied Carpet Beetle infestation, you should search for these indicators:
- Adult beetles flying near windows or caught in spider webs
- Holes, frayed edges, or bare patches on carpets, wool, or other natural fabrics
- Shed skins and fecal pellets around infested areas
It’s important to regularly inspect your carpets, furniture, and other belongings for signs of damage caused by these beetles.
Types of Damage
Carpet beetles can cause damage to a variety of materials in your home. Here are some examples:
- Carpets and rugs: Beetles chew holes, creating unsightly bare spots in natural fiber carpets.
- Wool clothing and blankets: Holes and worn edges can be found on wool items.
- Furniture and upholstery: Damage can occur to both natural fabrics like silk or leather and synthetic fabrics.
- Felt, lint, and other debris: Beetles feed on organic debris hidden behind or under furniture and along baseboards.
To protect your belongings, it’s essential to eliminate accumulations of lint, hair, dead insects, and other debris that serve as food for carpet beetles.
Keep in mind that although synthetic fabrics are not the primary food source for carpet beetles, they can still be damaged as beetles search for more preferred materials.
By staying vigilant and addressing any signs of infestation, you’ll be able to minimize the damage caused by varied carpet beetles in your home.
Prevention and Control
Cleaning and Vacuuming
One of the easiest ways to prevent and control Varied Carpet Beetles is through regular cleaning and vacuuming. It’s crucial to keep areas like attics, baseboards, and cracks free from dust and debris.
For optimal results, consider these practices:
- Vacuum furniture, carpets, and hard-to-reach areas.
- Make sure to clean food crumbs and pet hair.
- Regularly dry clean or wash your clothes and fabrics to remove potential larvae.
Being vigilant about your home’s cleanliness can make a significant difference in preventing a carpet beetle infestation.
In some cases, insecticides might be needed to control a more severe carpet beetle problem. Here are some tips on using insecticides:
- Apply them in crevices, cracks, and areas where carpet beetles are known to reside.
- Only use insecticides that are labeled safe for indoor use.
- Always follow the label instructions and safety guidelines.
However, you should note that insecticides specifically targeting Varied Carpet Beetles are typically less effective on the larvae compared to adult beetles. Also, remember that chemicals should not be your first option; always try regular cleaning and vacuuming first.
By consistently practicing good sanitation and employing appropriate measures like vacuuming and using insecticides when needed, you can effectively prevent and control Varied Carpet Beetle infestations in your home.
Comparison with Similar Species
When trying to identify the Varied Carpet Beetle, it’s helpful to be aware of some similar species. Here, we’ll compare it with the Black Carpet Beetle, Brown Carpet Beetle, Fur Beetle, and Bed Bugs. We’ll focus on differences in their head, legs, and abdomen characteristics.
First, let’s talk about the Black Carpet Beetle. You’ll notice that they are larger than Varied Carpet Beetles. Key differences include:
- Shiny black, slightly elongated body.
- Long, thin legs.
The Brown Carpet Beetle is another species to be aware of:
- Dark brown, round body.
- Short, sturdy legs.
Now, let’s consider the Fur Beetle:
- Round, black body with a white spot on each wing casing.
- Shorter legs compared to Black Carpet Beetles.
Finally, Bed Bugs can be mistaken for carpet beetles, but some distinctions set them apart:
- Oval-shaped, wingless body.
- Reddish-brown color.
Here’s a comparison table to make it easier to spot the differences:
|Varied Carpet Beetle||Round||Brown with white, yellow, and black||Short||–|
|Black Carpet Beetle||Elongated oval||Black||Thin, long||–|
|Brown Carpet Beetle||Round||Dark brown||Short||–|
|Fur Beetle||Round||Black with white spots||Short||–|
In summary, when identifying the Varied Carpet Beetle, look out for its round body, distinct color patterns, and short legs. Be sure to compare these features with other similar species, such as the Black Carpet Beetle, Brown Carpet Beetle, Fur Beetle, and Bed Bugs, before reaching a conclusion. Good luck with your beetle identification efforts!
Impact and Role in Ecosystem
As a Domestic Pest
The Varied Carpet Beetle, scientifically known as Attagenus pellio, is a common domestic pest. You might find them in your home where they feed on a variety of materials, including carpets, clothing, and wool. Here are some characteristics to help you identify them:
- Adult beetles: 1/10 to 1/8 inch long, nearly round, and gray to black1
- Larvae: Elongated, oval, reddish-brown, about 1/4 inch long, covered with many brownish-black hairs1
In your home, these pests can cause considerable damage to carpets, upholstery, clothing, and any other fabric-based items. If you come across an infestation, it’s essential to address it promptly.
As a Museum Pest
Museum pests, such as the Varied Carpet Beetle, can be a severe threat to natural history collections. The larvae feed on organic materials, such as hides, feathers, and insect collections. In this context, they can cause significant damage to precious specimens and artifacts, making pest management a top priority for museums.
Predators and Threats
Despite their status as pests, Varied Carpet Beetles have their fair share of predators and threats in the ecosystem. They are prey to several insects, birds, and small mammals in North America. Some common predators include:
- House Sparrows
- Ladybird beetles
The presence of these predators can help control the population of Varied Carpet Beetles and limit infestations in domestic and museum settings. However, an integrated pest management plan is necessary to effectively deal with these pests in sensitive locations like homes and museums.
Unique Features and Characteristics
Varied carpet beetles are small insects with quite a few unique features. Their adult form is round and oval shaped, measuring about 3-5 millimeters in size. These beetles are often confused with moths due to their similar appearance. One contrasting trait is their distinct wing patterns which are characterized by a mix of white, brown, and yellow scales.
These beetles have some distinctive habits as well. They are drawn to lights, often found around windows. Varied carpet beetle larvae prefer to hide in dark, undisturbed areas, close to their food sources such as lint and pet hair.
Now let’s take a look at the larvae of carpet beetles. These creatures exhibit alternating light and dark stripes, covered with tiny hairs, also known as horns. Interestingly, the hairs can be ‘puffed up’ when the larvae feel threatened. Larvae are the main culprits causing damage to carpets, furniture, and fabrics.
In different regions, the varied carpet beetle undergoes diapause, which is a period of dormancy to escape unfavorable conditions like cold temperatures. This adaptation allows them to survive in various climates and environments.
To help you visualize these characteristics, these are some key features and traits:
- Round, oval shape
- Size: 3-5 millimeters
- Drawn to lights, found around windows
- Larvae with striped patterns and hairs (horns)
- Adaptation: diapause
In summary, the varied carpet beetle has distinctive features, habits, and adaptive traits that make them unique in the insect world. Being aware of these characteristics can help you identify and manage their presence in your space.

Greetings from Southern California. We see examples of this crawling on our walls from time to time. Here’s a photo I took today myself March 5, 2013. The finger is to indicate the scale. My kids are concerned, though I’m sure it’s harmless. Many thanks.
It seems that in recent weeks, a significant percentage of our insect identification requests have been for Carpet Beetles, including the Varied Carpet Beetle, Anthrenus verbasci, the species in your image. Your photo is of a much higher quality than most of the requests we have received recently, so we are using your request as a feature on our site to inform our readers about Carpet Beetles. Carpet Beetles are common household pests that feed on a variety of organic items in the home, including “wide variety of materials of animal origin (wool, fur, skins…)(1); stored food materials and products (biscuits, cakes, seeds, wheat, maize, oats, rice, cayenne pepper, cacao, and dried cheese)” according to BugGuide. For clarification, only the larvae eat those items. Adults, which are frequently found on windowsills, feed on pollen.

Started seeing these little bugs in my carpet last night. I am a clean person, indoor only cat, I am distraught and couldn’t sleep last night knowing what I found. I inspected my cat but could not see anything in her fur and these don’t look like fleas anyway.
May you please tell me?
1) What they are?
2) How they got in my house?
3) How do I get rid of them?
4) How do I prevent this in the future?
1) You have Varied Carpet Beetles, Anthrenus verbasci.
2) They are very tiny and they might have entered the home through any small crack, crevice or gap that they found, either in the foundation, around a window or even when you were entering or leaving. The adults feed on pollen and they might have gained entry into the house by you when you brought yourself or a loved one a bouquet of posies and didn’t notice them among the petals. According to BugGuide, the larvae of Varied Carpet Beetles “feed [on] keratine and chitine, and may cause considerable damage on wool, fur, feathers, and natural history collections.“
3) You need to find the larval food supply in your home. They may even be feeding on items in the pantry. Pet hair that accumulates might also be a larval food source.
4) Most likely you cannot as they are a cosmopolitan household pest that is found in even the cleanest of homes. Vacuum more frequently and that might help.
Two of you photos appear to be a mating pair, though that might be an illusion of the camera.

I thought because I’ve found five or so on the bed it was bed bugs, but the pattern and the fact that they have wings hidden (like a lady bugs) indicates its not. I’ve have some possible “bites” on my stomach (which is covered when I sleep) and no where else. Went from panic to relieved, and hope this is the right reaction to have. They can eat my clothes, I don’t care as much if its if its not me…
You are correct that this is a Varied Carpet Beetle, and this year we have been receiving considerably more identification requests for them and in any other year, that we can remember. It seems there are about five reemails per day with images of Varied Carpet Beetles. Adult beetles feed on pollen, and the larva do the damage in the home. The larvae will eat organic items, and we don’t believe your clothes will be significantly damaged unless you favor furs and clothes with feathers. Your food items in the pantry are at a much greater risk of being eaten than your clothing is.

Dear whichever way seemed fit,
You have Varied Carpet Beetles, Anthrenus verbasci, a common household pest. The adults feed on Pollen and it is the larvae that do the damage in the home. According to BugGuide, they feed on a “wide variety of materials of animal origin (wool, fur, skins…)(1); stored food materials and products (biscuits, cakes, seeds, wheat, maize, oats, rice, cayenne pepper, cacao, and dried cheese); adults feed on pollen.” BugGuide also notes: “The most abundant species in buildings; arguably, world’s most important pest of insect collections. Adults from indoor populations have a negative attraction to light, but near the end of their oviposition period they become attracted to light. Adults from outdoor populations show attraction to light. Adults are active fliers and often fly high above the ground. They enter houses through open windows, around eaves, soffits, and attic vents, and often lay eggs in the dead insects collecting in light fixtures.”

Hi, found this on my parsley that is flowering already. any ideas?
These are Varied Carpet Beetles, Anthrenus verbasci, and the larvae can be a nuisance in the home. Some species in the genus are major threats to museum collections. The larvae eat organic fibers like wool and pet hair and they can also be found feeding on certain foods stored in the pantry. Adults feed on pollen. The adult beetles are not a threat to your garden, but if they enter the home and find a suitable environment, they will lay eggs and you may find the larvae troublesome. Here is the BugGuide food list: “wide variety of materials of animal origin (wool, fur, skins…)(1); stored food materials and products (biscuits, cakes, seeds, wheat, maize, oats, rice, cayenne pepper, cacao, and dried cheese); adults feed on pollen.”

We recently moved into a house and I have been finding these in my house along with larvae in the carpets. I’m pretty sure they are the ”varied carpet beetle” but am hoping there is a chance they are not so please identify. The majority of the adult beetles have been in the bathroom. I have found larvae in 3 bedrooms but only a few adults in one of the bedrooms. I suspect the previous residents were very dirty due to a few other things nasty things that I have discovered in the house. I find an average of 2-6 adults a day in the bathroom. A pest control man came out and sprayed some chemical that we had to leave the house for and said they’d be gone in 2 weeks. Well it has been over 2 weeks and they seem to be increasing. I’m going nuts vaccuming like mad, using diatomaceous earth in certain areas, bleaching the bathroom, caulking up cracks nothing is helping. I knocked old wasps nests off the house but they weren’t even anywhere n ear the area where the beetles are. Any advice?

First we want to console you that having Carpet Beetles in a very clean home is not uncommon. All you need to do is locate the source of the infestation. With the cleaning habits you describe, we are confident that once you find the source, you will not be troubled any longer by Carpet Beetles. You should not waste any more money on an exterminator who sprays the home randomly. Again, we must stress the importance of finding the source of the infestation. Carpet Beetles can live on a variety of organic fibers, including fur and feathers.

I took these pictures and was going to send them to see if you could help me identify the bug; my girlfriend has lived longer in the area, and was acquainted with them (although she knows them by the unofficial name ”Spring bugs”, as they appear at the beginning of the Spring).
Alas, when I opened the website, a photo that was highlighted on the homepage struck me as familiar: the bug I was looking for is the varied carpet beetle. So, with the identification solved thanks to your website (without requiring your direct intervention), here are the pictures I took. You may use them however you want, as long as you credit me ( as ”jcraveiro” ) – which is basically a CC by-sa ( http://creativecommons.org/licenses/by-sa/3.0/ ) license.
We are happy to hear you were able to easily identify your Varied Carpet Beetle using our website. We have since removed the featured Carpet Beetle posting, but as we are continuing to get numerous identification requests for Carpet Beetles, we will use your letter as the new featured posting. Varied Carpet Beetles are common cosmopolitan household pests, and though the adults feed on pollen, the larvae feed on a large variety of organic materials in the home. according to BugGuide: “larvae scavenge on accumulated fur, feathers, skin flakes, dead insects, etc. keratine- or chitin-rich materials; adults feed on pollen on flowers. Typical household products consumed include dry pet food, wool blankets/clothes, furs, and hair and skin flakes shed by people and pets and accumulated in the corners.” We are using your photo in both a cropped (to give a better view of the Varied Carpet Beetle) and an uncropped form (to better give an idea of scale).

You have Varied Carpet Beetles, Anthrenus verbasci , currently our most common identification request with an average of five requests arriving daily. Varied Carpet Beetles are members of the family Dermestidae, a group that contains many members that are cosmopolitan and that infest homes. The adults, which you are finding, feed on pollen, and they are likely congregating on the window sills in an attempt to gain access to the outdoors. The larvae are the pests that infest homes. According to BugGuide, they are “primarily a household pest on plant (dried fruits/nuts) and animal materials; regularly encountered in dried-milk factories, occasionally in flour mills and warehouses” and they eat a “wide variety of materials of animal origin (wool, fur, skins…)(1); stored food materials and products (biscuits, cakes, seeds, wheat, maize, oats, rice, cayenne pepper, cacao, and dried cheese)”. They are reviled in museums and BugGuide also notes they are: “arguably, world’s most important pest of insect collections.” The best way to eliminate them from the home, in fact the only way to eliminate them from the home, is to identify the source of the infestation, the place where the larvae are feeding, and discard any food or other item that might be feeding the larvae.

They enter houses through open windows, around eaves, soffits, and attic vents, and often lay eggs in the dead insects collecting in light fixtures.” Adults feed on pollen and it is the larvae that do the damage. According to BugGuide, the larvae feed on a: “wide variety of materials of animal origin (wool, fur, skins…)(1); stored food materials and products (biscuits, cakes, seeds, wheat, maize, oats, rice, cayenne pepper, cacao, and dried cheese).” We were about to inform you that we believed your beetles were most likely trying to leave the home since adults that emerge from larvae that have been feeding indoors are attracted to windows, but according to BugGuide: “Field strains have an apparent diapause and must experience cold temperatures to produce adults in the spring; household strains produce adults in the fall.” Since you have a spring sighting, it is most likely they are entering the home if that information is correct. It might be difficult to seal your home from such a tiny invader, but keeping careful watch on the stored foods in the pantry may help control the indoor population. We once had Carpet Beetles devour some papier mache masks we made from newspaper and flour paste.

It is a very small beetle. I think it may bite. Found while lying in my bed reading (not under the covers).

I have found this bug all around my house. On my couch, on the floor, on the wall. It is winter now though there are more in the summer. I am in south Texas.
This is an adult Variegated Carpet Beetle or Varied Carpet Beetle and they often attract attention when they congregate at windows in an effort to leave the home. Adult Carpet Beetles feed on pollen, but the larvae of Carpet Beetles feed on a “wide variety of materials of animal origin (wool, fur, skins…)(1); stored food materials and products (biscuits, cakes, seeds, wheat, maize, oats, rice, cayenne pepper, cacao, and dried cheese); adults feed on pollen” according to BugGuide. The larvae will also feed on the dead insects that accumulate in light fixtures and windowsills.

One picture is the top view and the other is the bottom view. The top view of the bug appears to show wings ont he tail section, how I have not observed these bugs in flight.
