We're having an outdoor cookout for Memorial Day and always seem to be bothered with house flies. Is there anything that will get rid of these nasty things at least for the day? Thanks for your time.
When we were in Perto Rico the street side cafes used 2 liter coke bottles filled with water. The venders say the bottle of water messes up the fly's eyesight. All last Summer I tied said bottles to our patio cover and NO flies.
Worked great for me.
What do you have to lose???
