i love any type of bee. but this year the carpenters are off the chart. they're so busy chewing my pine planter boxes on my porch they don't even stop when I bang on the sides of the planter. the frass is in piles on the porch floor. I can hear them chewing from the driveway. Since I don't want to hurt them I put aluminum baking pans on the bottom of the planters-with T-REX tape- and that seems to be working for now.. It got to the point where all you could hear was the chewing and gnawing. I do like the idea of having an area for them to live in the drilled out logs. Sweet! A bee condo.
