Varied Carpet Beetle

Asked August 22, 2016, 10:44 PM EDT

Over the past few weeks, I have found mature carpet beetles (at a rate of about 2/day, but sometimes as many as 4/day). I have found them ONLY on one particular windowsill in my kitchen. I have yet to determine the source of the infestation. My question is this: how far will the adults typically "venture" inside the house? My house is a somewhat large 1960s style ranch in Southern California. I am a fairly fastidious housekeeper and and frustrated that I can't spot the larvae casts. Can the location of the adults help to narrow down the infestation? Any other tips you could offer? I had my wool and silk rugs cleaned in July.

The link above takes you to some good info on carpet beetles from UC. there are lots of places larvae may be feeding other than carpets: stuffed animals, wool clothing or blankets, just to name a few. Larvae are typically going to feed in dark, secluded places- so start by looking for appropriate items that might have small "dust" particles below- This will be the fecal matter of the larvae. For instance, if you found the "dust" on a closet floor, and there was an old wool jacket above the dust on the floor.
Adults are drawn to sunlight - they are searching for pollen and nectar. They are going to head to the closest window- so start your search in dark, less used spaces close to that window. Hope you find this helpful, Nicole

Thank you. :)

my pleasure and good luck!
