Hi - new poster here.

Wonder if anyone can help. My front garden has seen a large number of small piles of earth form with a hole in the middle. There are probably about 50 of them at a conservative guess. The hole itself is about 6mm and like someone has used a drillbit, with the earth making a small mound about 3cm wide and a couple of cm tall. I've seen some very small "bee like" things around.

The front lawn has an apple tree in it, and the holes are in that area of the lawn.

So far the little things haven't caused me any harm - and while I don't want to kill them, I equally don't want an army of bees living under my lawn. There are also young kids that play out in my street as we're on a cul-de-sac and I'd hate for one to get stung.

Any advice or guidance would be gratefully received.

Apologies in advance if I've posted in the wrong section.

Mark.
