Thanks liz, I'll check that out. Just checked a small cabin we have in the woods and they've almost demolished the rafters in the porch ceiling! I really need something to stop them *before* they dig the little holes. Tried spraying the wood with Dursban (they don't sell that anymore) but even that only slows them down for a few weeks. They sure are tough little devils.
well we have never had them that bad to my knowledge. I would try contacting a pest control and see what they do to get rid of them or keep them away. A lot of times they will come out and give free estimates and then you will get an idea for their plan and if you think it will work or if it is somethign you can do yourself
