Bee that drills in wood

I've been seeing this big bee drilling holes in my deck. What kind of bee is it and what can I do to stop it from destroying my house??

What you're seeing is a carpenter bee. They are very active in the spring as this is the time when females drill holes to start nests. We have an in depth article about CARPENTER BEE CONTROL which  highlights all you'll need to know about this pest and how to treat. First, read the article. Then get some Drione and Cypermethrin to stop the damage from getting any worse.
