Wasps are making nest (i think) in a gap between the shed wall and the floor. I ignored it 1st but now they have stung our little daughter. I filled the gap with something but they found a new place to move, filled that and now they are on their 3rd spot in the same area. What is the best way to get rid off 'em? Its near the bins so no one will go out to throw waste in bins, also very close to the kitchen window which is now kept close all day! Any suggestion?
