Do you have a smoker? If not, it would be a worthy investment, as smoke calms the bees. They gorge themselves on honey and it's kind of like having Christmas or thanksgiving dinner ... You don't want to fight too much on a full stomach.

If you don't want to calm the bees, then the only other option is to have a beekeeper come and remove them for you.

Are they honey bees or yellow jackets? If they are honey bees your county farm bureau may be able to contact someone to help remove them safely.
