Carpet Beetle


Those darn kids! It's not the adult carpet beetle that causes the problem; it is the larval stage in the carpet beetle's life that causes damage to carpets and other fabrics inside the home.  The larvae of carpet beetle are about a ΒΌ inch long and look like a brown caterpillar covered with short bristles. They prefer dark, secluded places like closets, attics or the spaces behind walls and under floors.

The adult beetle is about the same size but enjoys sunlight and feeds on pollen and nectar. But, because the adults are more open about their

presence, they get blamed for everything. Adult carpet beetles shiny black or brightly colored depending on the species. Finding adult carpet beetles indoors on window sills may indicate a larval infestation somewhere in the house.

The larvae of carpet beetles move around from room to room, so the source of an infestation can be difficult to locate and treat. The best way to treat for carpet beetles is to keep areas clean of animal hair, dust, old spider webs or soiled fabrics. Carpet beetle larvae really like that stuff. Vacuum frequently with a beater-bar vacuum cleaner to eliminate eggs lying in the carpets. Eliminating food sources is the best way of preventing carpet beetles, but identifying where they are coming from is the first step in getting rid of an

existing infestation.

Carpet beetles originate from an old bird's nest or dead animal hidden behind a wall. Old cereal in boxes or other grains can be good food sources for carpet beetles, too. Adult carpet beetles can be brought into the house on cut flowers. Finding molted shed skins that look like the larva of the beetle, but crusty and brittle, can help you to locate where the beetles are feeding.

If you discover carpet beetle damage on clothing you will need to do a thorough house cleaning including emptying, vacuuming and treating dressers, closets or other storage areas with prescribed pesticides. You need to kill the eggs, larva, and adult forms of the insect to get control. Roughly brush the clothing to kill eggs. Avoid spraying pesticides on clothing, of course. When storing fabrics, seal them in air tight containers and add moth balls or resin strips to keep beetles out and to kill larvae. Resin strips must be used in airtight places so the pesticide can build up in the air, if there is a leak the larvae can survive and keep on feeding. A negative about using mothballs is that everyone within a hundred feet of you will know you are coming before you get there. Same problem with putting clothing in cedar closets. The smell announces your entrance .

If you aren't sure that it is carpet beetles damaging your belongings you can

purchase carpet beetle traps from various on-line web sites. Placing traps around the house will help you determine where the carpet beetles are coming from.

Carpet beetle feeding patterns are similar to clothes moths, but carpet beetles generally feed on one large area rather than leaving many small holes. Sometimes carpet beetles will eat objects you wouldn't expect like the felt and hammer inside a piano. The beetles also will eat stuffed animals or the horns of mounted animals. Museums with animals on display often have this problem.

If you want to eliminate carpet beetles but don't want to fumigate or use pesticides then you can freeze infested objects for two weeks or heat the object for thirty minutes at 120 degrees Fahrenheit. Obviously, these solutions will only work on smaller objects. If it's your carpet that is infested you have little choice, but to treat yourself or call in a professional pest control company to do the work.

I am a costumer, so I have a fair amount of fabric that I keep in my apartment. (an older Victorian house) I recently discovered a larval black carpet beetle infestation in some pieces of wool that I had sitting in my sewing room while I was away over the summer. When I started cleaning my apartment, I also discovered a couple in my couch. I have disposed of the wool piece that was infested, and thoroughly vacuumed my couch,living room, and sewing area. I don't have any carpets, the apartment is all hardwood, and I have very little upholstered furniture. just two small couches.
I hate to throw out more material or my expensive wool yarns if they aren't ruined though. Does washing in hot water and drying on high really kill the little critters? And they won't hang out in the washer/dryer afterward to transfer to my regular clothes will they?
Should I be more concerned about them continuing to multiply, or should I just clean everything really well and keep an eye on things?
Thank you so much for any help.

I found some carpet beetle larva in my clothing and have since washed everything I own. I am still finding small black specs on the carpet which I am gussing is them shedding? I sprayed pesticide meant to kill carpet beetles around the baseboards twice and had an exterminator spray once so far. How am I supposed to kill these things? Most of the larva I have been finding now is dead but then why are they still pupating or whatever you may call it? I want to be rid of these things for good. I also cleaned every inch of my rug with borax and everything, I don't know what else I can do. I am worried about them moving into my funiture.

I have antique braided wool rugs in most rooms in my home. The guest room is rarely used. I was cleaning it for company and noticed a hidden side was completely chewed/destroyed,(about 6 inch area) and tons of tiny pellets/round, on the ground. Then I noticed small holes in the hardwood floor, around the eaten rug area. Some of the holes seemed to have a thin, hard cover, which I removed with my thumbnail. I saw one tiny 1/2 inch or less whiteish worm/caterpillar, and squished it with my finger before thinking to save for reference. Then my husband fogged the room. A few days later I checked the area and sure enough, more tiny pellets, but also 3 dead wormlike insects. What eats wool and bores into hardwood? Do I need to tent my house? Any info appreciated. Thanks, Janice

We have found a carpet beetle infestation in our mattress and sheets. My mom and I were both bitten up sleeping in her bed and it was infested with the carpet beetles (in the mattress and mattress cover.) The local exterminator defined the bugs as carpet beetles. Can they cause these kind of bites and how can we keep the house clear of them? We live over a crawl space in a ranch house with 3 cats that don't go out and 3 birds. Thank you.

I have tiny, black bugs that fly in my house mainly on floor & carpet. They crawl over my pants. They bite and suck blood. Are they carpet bites?

The bites itch a lot. Please advise

Thanks

I have found live carpet beetle larvae on my clothes in the closet. I have a lot of clothes, two FULL closets. I want these devils gone!! I was thinking of using a pesticide around inside the house, but I have a dog and cat that I am concerned about. The house is about 1000 sq ft. with all hardwood floors. I am limited by space so the closets are packed pretty full. What can i do with all the clothes? Wash them all, freeze them...I am afraid there are beetles between the folded clothes. Help please!!

Thanks,
KD

We recently experienced bites, and discovered several wooly bear larvae under our bed, so I'm interested to hear if carpet beetles do indeed bite.

I have found small black larvae crawling in the corners and on some clothes in the master bedroom. The first time I noticed was late summer, I swept them and cleaned the area with warm soapy water, now it is winter and I am starting to see more, they are very small and could be missed unless you see the tiny larvae moving. What must I do to rid my home of these regardless if they are moth or beetle larvae.

I found larva on my boxsprings and have bites on my legs and arm. I looked through various pics of larva and found a pic that looks like them. They are oval shaped, tiny larva and are dark on each end and light in the middle. The pics that look the most like it are carpet beetles. How do I get rid of them?

We have had tons of insect problems since building a new house.
Four different times the university has identified carpet beetle larvea and I could not even see these with the naked eye. I had a small miscroscope and had abeen looking for wood boring insects and these were just in with samples.
Last fall when I brought out winter clothes I found them and now I have holes in clothings and I will feel things crawling inside if I don't keep clothes in totes and wash in real hot water. It this uncommon to feel like there is something crawling inside of your clothes?
I will find small lint like balls that dont look like anything inside them, but after I either pull off this fuzzy ball then it stops.
Sometimes there will be to many and now in towels and comfortors that threads are breaking when I try to steam them these same fuzzy balls will come out.
