I tried accessing your site but it was down due to too much traffic. Congratulations, I guess!! 🙂 Anyway, yesterday I noticed about 5-6 really large bees hovering outside my screened porch in Birmingham, AL. They weren’t digging in the wood, just walking all over the screen, like they were trying to nest there. Today, there must have been 2-3 dozen of them. I sprayed them repeatedly, many died, but most came back for more.
Needless to say, we were totally icked out and want these large things gone if possible. Can you tell us who this is that has invaded our home. I’ve attached a picture that shows three of them after they’ve been nuked and out in the sun for some time. What are these scary invaders? Thanks for your help and your great insight and web site.
Dear Ben Fineburg,
Yes, we are down due to heavy traffic, thanks in part to the USA Today Hot Site selection on 7 June. We have just paid for an upgrade and expect to be back up within 24 hours. Your bees look similar, but slenderer than our California Carpenter Bees. It is possible that a female dug a burrow and her brood has recently emerged. Young bees will rest awhile before taking flight. Carpenter Bees can cause considerable damage to wood, but they generally are not aggressive and are reluctant to sting. They are solitary bees, meaning they do not form a hive proper. A female will excavate a burrow in the wood and lay several dozen eggs. Like I said, your specimens look slender, but they could be Xylocopa virginica or a close relative.
