Yuck! We’ve got loads of flies appearing from somewhere. Every time we turn our backs, the landing has been infested again. Ok, so it’s only 5 or 6 of them at a time, but that’s 5 or 6 too many.
I’ve just taped up the crack around the loft in the hope that that’s their route. If the population drops over the next 24 hours, that must be the source.
