I was vacationing in the Newcastle area nearish to Scotland for the most part, and I certainly didn’t notice mosquitos like we have in Canada, but even just random spiders and flies and stuff were constantly coming inside with open windows.

It’s not the end of the world, but neither is installing a screen, it just seemed strange how universally uncommon they were. Like I figured that at least some people would still hate bugs enough to install them.

Okay but I know the UK has rodents. If I left my grond floor windows open we'd get mice inside.
