How do you get rid of carpenter bees safely without harming the nests?

- Firstly, liberally apply an organic insect REPELLANT (rather than insecticide) that will not damage the wood (they should be safe, especially if licensed for use on human skin). Again, do this at night, wear protective clothing.

- Re-apply repeatedly, and observe the nest for a few days.

- If the bees are returning, block up the hole with caulk or sealant. Paint the area. Spray a repellent around the area -- such as surrounding brick work, and keep repeating. The objective is to discourage the bees from coming back.

I have often wondered whether it may also work to place old, unpainted wood close by, to encourage the bees to nest there instead, should they return. The piece of wood could then be relocated elsewhere. Perhaps you could try it?

If absolutely necessary, you may need to replace wood, if the damage is great.
