<p>We did put a couple of those bag type fly traps outside this year— they work like a dream! The satisfaction of seeing hundreds of flies in a trap is bizarre! Clearly I need therapy.
I think these are just for outside—but they are non toxic–so maybe hang them in a closed room for a night and see what happens? I know they stink (that’s why the flies love them duh?) so closing the room off is a must—but I do feel your pain. I hate flies.</p>
