Did you put cellophane over your glass of apple cider vinegar and poke tiny holes in it? Surprised it didn’t work. Worked great for me.
Take an empty food can with a banana peel in it, and place some cling wrap on top with a small hole. Wait a few hours, put your hand over it, take outside and release the flies. Repeat as necessary.
Yes, we did. It caught some bugs, and so did the red wine; but nothing like the scores that the beer and Raid did.
Thanks very much for your response.
