What kind of bug is this?
Location: Manayunk, Philadelphia, PA

Found it crawling on a sweater I discarded on the floor after a night of drinking. I could have picked up the bug at any of these places:
-dry cleaners (where the sweater came from)
-a drinking establishment
-my couch
-my bedroom floor
Please advise!

Smooth Spider Beetle

Dear Resident,
As much as we are amused that you may have picked up this Smooth Spider Beetle,
Gibbium aequinoctiale, in a drinking establishment, we would put money on your couch or your bedroom floor.  Spider Beetles are known to infest stored foods in the pantry, and you may want to check any food that has been unused for past the expiration date to see if it is contaminated.  The BugGuide may have additional useful information for you.

What is this tiny black bug with stipes?

I have lived in my home for 16 years. This tiny bug has suddenly started coming into my house. It is entering between the small crevice between the large window and window sill. Can you help me identify it and tell me what I can do to stop this bug from entering my home?
Signature: Thank you, I really appreciate your help – Lisa :o)

Varied Carpet Beetles

Dear Lisa,
You have Carpet Beetles, probably Varied Carpet Beetles,
Anthrenus verbasci.  This is a common and cosmopolitan household pest.  According to BugGuide it is:  “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.”  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.

I think this is a varied carpet beetle

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?

Varied Carpet Beetle

Dear Eap,
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.

Carpet Beetle

Dear DM,
In our most imaginative and melodramatic moments, we can conceive of a scenario where this domestic pest, a Carpet Beetle, might be dangerous, like
larvae feeding off household woolen goods might do so much damage that the fibers might disintegrate when most needed for a rescue.  One of our readers posed an asthma question once, though we are not medical experts and we would hate to speculate without research.   Of all the species of Anthremus pictured on BugGuide, this looks the closest to the Buffalo Carpet Beetle which is documented as far west as Colorado on BugGuide’s Data Page.  The reddish markings are not as prominent on your specimen, so perhaps this is an isolated western population that has begun to diverge in characteristics from its eastern relatives.

Buffalo Carpet Beetle? or other???

Possibly Sawtooth Grain Beetle

Dear Wtgrot,
It is difficult to be certain because the resolution on your image is so poor and when the underexposure is corrected, there is a great deal of visual noise, but this might be a Sawtooth Grain Beetle,
Oryzaephilus surinamensis, see BugGuide.  If we are correct, you might want to check stored grain in the pantry, or possibly even large quantities of bird seed or pet food.
