Read a post on BYC last week to make a homemade fly trap. Used syrup and ACV. My husband had an idea also.....beer...so we both made our traps, and his trap started out in the lead but by the second day, mine had passed his by a mile...We were laughing all weekend comparing traps...what a way to pass the time huh??? Edited to say that I might switch to molasses...that would really have em coming!!!
