Just found out I have Powderpost Beetles in my wood. My research says that Borate is needed to kill them. I know I should not be getting out due to the Covid-19 lock down but I can't let them eat my bed up. They are working fast. I can wipe away the dust and 10 minutes later it's back.
It does look like you have powder post beetles. They can be a problem with wood that has not been kiln dried. Borates work, but they will not soak into the wood with that finish you have applied to the surface. Given the situation you have, I would try to "fumigate" them in a sense of the word. Try spraying the impacted surface with some kerosene trying to get the liquid to seep into the galleries (holes). The petrochemical has a pretty lethal vapor that may kill them if they are deprived of oxygen. Apply in the shade and let sit for a while before wiping the surface clean. Monitor and reapply if necessary, but hopefully the beetles infested the wood while in storage and you can eliminate the problem with your "bed bugs".
