Can't you get the council to sort it Sprouty?
I've never looked into it TBH Moons, It's only one or two. I just open the window and usher them out
contact the council's environmental health and pest control dept.
They will arrange a visit at a time that suits you,nothing to lose Sprout . .
We have to pay for that service here, erin - it's only free to pensioners. I thought I had a wasps nest too a couple of years ago - kept finding lots of them - I got a pest control company out, and he inspected the loft etc but there was nothing there - he just thought it was coincidence. Didn't charge either, which pleased me!
Are you kidding?
