How to stop bumble bee's from drilling treated deck?

I am not sure if drilling is the correct term but we have bumble bee's hanging around under the benches of our deck and big piles of saw dust under the bench! Does anyone know how to stop this, I have tried coating the wood with flying insect spray and it didn't work. Any suggestion's would be greatly appreciated!How to stop bumble bee's from drilling treated deck?
Those are carpenter bees and I have them here in Delaware. They drill the hole to make a space for the queen bee to lay her eggs.





You can probably get an exterminator to spray the wood with stuff these bees wouldn't like to be around. Or you can go to Tru Value and get anti bee stuff yourself.

If you don't like poison, maybe you could cover the areas with some kind of decorative plastic that they can't bore through.





They are really carpenter bees I think.
Fill the holes with wood putty. It discourages them from re-drilling.
2 parts orange oil to 1 part water. Use paint brush or rag to rub on wooden parts only.Or lavender or spearmint oil
