My DM is upset that she hasn't see the blue tits going into her bird box for a few weeks. She mentioned she'd seen bees including a huge one (Queen?) so gave it a little shake and soon some bees came out before going back in. We saw the Queen fly off and then come back.
She obviously wants to get rid of them but we aren't sure how to go about it. Do we lean out of the window and put the bird box into a bag and then take it elsewhere and release them? Would we get stung? They're not like homing pigeons are they? 
Ideas anyone? (I've googled and they aren't honey bees).
