I have a friend who lives in/near Denver who told me she's got an increasing number of bees entering/exiting from one of her door frames. I advised her of the pitfalls of calling an exterminator (or spraying herself) and recommended contacting a local beek assn to help find someone to perform either a cut-out or trap-out. I also told her I would post here to see if anyone nearby was interested.

Have asked for a better idea of her location and pictures of the bees. She's antsy because she claims allergy to stings.
