We have a log cabin in British Columbia, Canada – on a lake in a heavy treed area as well. Besides the bats, and stink bugs – we re-chinked now that the cabin has settled. We noticed the railings that were not sealed after staining , have wasps eating away at the wood all day. If we sand, restain and seal – will this keep the wasps away or will they eat through even with a sealant or cetol? I will wait for your reply.
