I have a bunch of rough oak boards sawn from a neighbors oak tree. I am seeing that there are beetles in it. There are small holes surrounded with fine dust. I tried solarizing but that didn’t work and now it’s getting cold here, so I’m looking for another way to get rid of them. The stack is about 8feet long and 3 feet high, so not a massive amount of wood. Should I use an insecticide?
