I'm pretty sure theyre just simple house flies, but they are REALLY annoying. we are careful about opening doors and never leave them open, but whenever someone goes in or out, somehow, there happens to be a fly there at that moment and it flies into the house!
it takes forever to follow them and swat them, so we usually open windows and then close them when the fly goes in it.
but a day or two later eggs hatch and we have 6+ more. its driving me crazy. are there any bug catchers/repellents we can put outside to get rid of or at least lessen the problem?
