I have an autistic child that hates flies and has meltdowns when they come in the house, I have to keep all windows closed all the time but we still get the occasional ones in. I’ve tried those hanging ceiling traps even though I hate them but they don’t even land on them! Fly spray is out as we have fish, what else can I do to get rid of them once they get in the house?! The meltdowns are driving me crazy.
