Query: Doesn't work at all

After a week of hanging up right in the middle of the swarm of flies on my basement, it hasn't caught a single fly. The flies are constantly flying all around both of these that I hung, and I'd be flabbergasted if some weren't bumping into it even just by random accident, but not a single one has stuck to it. Don't buy these!
