David Meiland Posted January 27, 2018 Report Share Posted January 27, 2018 Was removing carpet in a slab-on-grade bedroom addition and found the wood debris in the attached photo in a couple of spots. Looks to me like someone's been tunneling the PT bottom plate. Found a couple of possible culprits as well. Can anyone ID? Quote Link to comment Share on other sites More sharing options...
Jim Katen Posted January 27, 2018 Report Share Posted January 27, 2018 The debris looks like it might contain some pupal cases from ants, but probably not carpenter ants. Probably some nondescript little ants; the kind that people call "sugar ants." The first culprit is some kind of rove beetle. Possibly the one romantically called the devil's coachman. The other is just a garden variety beetle. No idea what kind, but not one of the wood borers. I'd just vacuum up the debris, and sprinkle a little boric acid on the perimeter of the slab before installing the new carpet. Quote Link to comment Share on other sites More sharing options...
DavidMartin Posted June 7, 2018 Report Share Posted June 7, 2018 I think it looks like beetles. Quote Link to comment Share on other sites More sharing options...

John Kogel Posted October 7, 2018 Report Share Posted October 7, 2018 Carpenter ants is more likely. They are more industrious that beetles, constantly cleaning house. I have seen this mess in my own house and have done the forensics.☹️ Quote Link to comment Share on other sites More sharing options...
John Ghent Posted October 8, 2018 Report Share Posted October 8, 2018 Here is a pix of a black carpet beetle. The debris does not look like carpenter ants which leave a frass that looks like it came from sawn wood. Quote Link to comment Share on other sites More sharing options...
