Come fly with me ...

Is it only this village (at least I know it's not just Genie Towers, thankfully!), or is the current plague of houseflies national? I hate using flysprays, especially in the kitchen, and prefer judiciously placed (so that nobody gets their hair stuck) flypapers. Two years ago a single flypaper lasted a couple of months. Last year I didn't need to use one at all. This year they last two weeks tops. The last one I hung up had three flies stuck to it before I'd put away the kitchen chair I'd been standing (oh god, my vertigo!) to hang the damn thing. The bloody things are everywhere.
