Bees nest in shed...I think.

I had a bees nest in my old shed over the allotment and asked the bee keepers on site what I should do.

I was informed they were male bees that were visable waiting for a queen to emerge and then try and mate with her. Apparently male bees cant sting but I never chanced it, activity lasted about 4 months

I had a couple of wasp nests in the ground a few years back....funny but they disappeared when I had a fire there
