One of our locations is right night to a creek and we have a constant battle with flies an moths late after the sun goes down. We have a fly light w/ sticky pad that gets them all over night after we close, but still have a problem while we're open. They're attracted to the light of the store and come in when customers open the front door and when delivery drivers open the back door. I would like to add air curtains to both doors. My concern is that customers will complain about it on the front door (messing their hair up?). It is a small take out only location so do not have to worry about any dining in issues. Does anyone here use an air curtain? Do you get complaints?
