Tiny bugs on windowsill
January 11, 2010
Every hour I have to vacuum these MANY tiny bugs from my window sills in the front room of my home. They sometimes appear on my kitchen stove (although less often), and the kitchen window sill as well. Most of the time they are either dead, or are dying (or they appear to be). I have even found them crawling on my neck! I can’t seem to find out how they are getting in my home, although i suspect they are crawling in through cracks or small openings in and around the windows. They seem to accumulate near the window where my wood stove is located. Thank you for your help in identifying these pests, and please let me know if I need to exterminate.

Dear Baffled,
WE are also a bit puzzled. The distinctive shape of your beetle and the clubbed antennae disqualifies most of the typical household pantry beetles we typically identify. We have eliminated the North American Flour Beetle, Tribolium brevicornis, which can be viewed on BugGuide. We believe your culprits are in the superfamily Bostrichoidea, which contains many household intruders, including Carpet Beetles, Powder Post Beetles, Deathwatch Beetles, and Spider Beetles, but we had no luck sorting through the superfamily on BugGuide. We can tell you what it is not, but not what it is. It is the middle of the night, and we will have to wait until tomorrow for a response, but we hope Eric Eaton will have more luck with the identity of this curious specimen.

Daniel:
Good news: The beetles are not infesting any foods in the pantry, or clothing in the closet. The image shows some kind of bark or ambrosia beetle, family Curculionidae, subfamily Scolytinae. I am not a specialist in these, but I do know someone who is (Dr. Stephanie Dole), and will see what she has to say. I’d bet these are emerging from stored firewood.

I’m very relieved to hear that! Thank you very much! I wonder, though, why these bugs seem to be coming in from where the windows are (One window is about 2-3 feet away from the wood stove). Our firewood is stored outside, and only brought in as needed. If they are somehow in/on the firewood, how did they get on the windowsills? We have two Bay windows, and each are approximately 9-10 feet apart from one another.
