can anyone tell me what kind of bee this is?

They have a nest in one of my pot planters on the deck...I thought it was a wrens nest and when I started to clean it out the bees came out...they are burrowing in the soil as well....thanks.

picture of the nest after I was removing it...it looks a bit papery I think too...I noticed that and thought ..hmmmm maybe bees...and sure enough...but I don't know what they are and if I should exterminate them or not....they are right next to our grill on the deck, so not a good spot if they will sting...which I think most will if you are near the nest...

a little better picture..they are still active in the dirt and around the container, but not really acting like they are going to sting...just intimidating me...lol

one flying...you can't tell a lot but it is an okay picture....they are QUICK LOL

Bumblebee.They commonly nest in debris or in the ground.

Thanks, I couldn't tell the difference between the bumble bee and the carpenter bee pictures...so I wasn't sure which it was...thanks for your reply.

On a bright side, they are Good polinators, whitch is why I don't bother them.
