I took these close up photos today of a powderpost beetle. I found this carcass in a small pile of frass (bug excrement) on a window sill. This is easily confirmed visually to be an adult ‘Anobiid’ species by reference to the University of Kentucky’s Dept of Entomology’s excellent Entfact 616 (on line). The bug almost certainly arrived as a larvae in the wood which is about five years old. The localized infestation is in a structural LVL – which fortunately is exposed and unfinished so it should be spot treatable as described by UKDE with low toxicity borate based ‘Timbor’. I have ordered a bag of TImbor on line for about ten dollars. Based on UKDE it should provide decades of protection against reinfestation and will knock down these little buggers as they emerge in their normal annual cycle. I will report back as I monitor this situation closely over the next year.
