Bugs coming from firewood?
January 17, 2010
I’m finding these bugs in our house and they seem to be coming from our firewood. We do keep some wood in the house for use and have a couple of racks outside our house.

Longhorned Borer Beetle

Hi Bill,
Our eyes are crossed from clicking through all the pages of BugGuide’s Cerambycidae section to no avail.  We had hoped to identify the species, but the best we can do is the family Cerambycidae, the Longhorned Borer Beetles.  We will see if Eric Eaton can provide a species identification.  Firewood brought indoors often causes dormant wood boring insects to emerge due to the warmth indoors.

Hi, Daniel:
The actual beetle specimens are longhorned woodborers, Phymatoes varius in all likelihood.  There are no images of this species on Bugguide currently, so we would welcome the person to submit them there.  We also have some top-notch cerambycid experts who could confirm or correct my own ID.

Hi Daniel & Eric,
I’d be happy to post the images, however I don’t know how. If you would like to post them, feel free to do so. Is there any problem with finding these insects in our home? I wanted to make sure they weren’t termites, which may be a problem.
Thanks for your help,
Bill

The adult insects are not interested in wood as that is the larval food.  Borers do not infest milled lumber, though there is occasionally a possibility of the larvae surviving the milling process and then emerging from furniture or structural beams many years later.  That is a rare occurrence.
