Does anyone have a good solution for discouraging flies & mosquitoes from hanging around in basement entrances? I think they like the cool & dark down there, and so have been especially bad this summer. I power-wash the walls fairly often, keep the drain clear and practice good mosquito-prevention in the yard (no standing water etc.) I hang strips of fly-paper, but there are still lots of them.
I’ve checked out some zappers online but they seem like overkill. Considered spreading some lime or desiccant, but it’s a small area and an active entrance to the basement apartment. Any ideas?”
