As well as several kinds of wasps, we also have Carpenter bees which unfortunately are not so harmless, the females burrow into wood and will also sting to protect their nests. One was burrowing into our new bathroom door today! The burned oil didn’t seem to put it off much either, but some research revealed that they do much prefer fresh unpainted wood, so I’ve tried screwing an unpainted piece to the door in the hopes that it will use that area when it comes back next – I also drew a bee-friendly symbol on it which should help it decide 🙂
