In the Summer of 2025, the flies were just horrifying. Being so hot and dry outdoors they seemed to congregate anywhere there was some shade. Thousands upon thousands of them. It wasn’t just me, either. Everyone else I spoke to about it was experiencing exactly the same problem.
These are two strips of fly paper that I’d hung in the workshop about an hour earlier.

Every morning for several weeks I was replacing the strips because in just one day they’d become so full of flies that there was no room for more. Obviously I put the full ones on the compost heap. No sense wasting them.
(Ignore the mess of the workshop. It was in the middle of a major reorganisation.)
