How do I keep wood bees away from my deck? You know the kind I'm talking about... the huge ones that resemble bumble bees. I'm deathly afraid of bees as I am allergic to bee stings. I don't want to wait until dark before I can enjoy my deck!

Good luck

Those are carpenter bees. We have to deal with them every year. See this post:
