Carpenter Bees Destroy Deck!
Location = Canton, MA
Sorry for the sweaty unkempt appearance in the picture. It was only about 98 degrees outside and I just came from a home being riddled by carpenter bees. The picture should give you some indication of the damage the Carpenter Bees did. The wood shown in the picture was from the back deck and this was just a small 2’x6’ deck plank. This small section had eight holes bored into it. Every deck plank had between 4-10 holes in it! The deck was being riddled with over 50 galleries in it. The entrance & exit holes you see are about ½” in diameter and perfectly round and look like they were drilled by a carpenter, hence their name. In fact many people mistake their holes as man made because they are so perfect. These galleries (tunnels) can extend several inches and when you have numerous galleries that is when the structural integrity becomes an issue. They place an insect inside, then their eggs, then use the frass (sawdust) to create galleries to protect their offspring.
A pretty amazing little insect and just another hot day in the wonderfully amazing world of pest control.
