Query: Attracts the Flies

We live near dairies so the fly problem is quite the challenge. Even these bags can't keep up but I'm not sure anything would. The smell isn't bad if you place them down wind and away from doors / windows. Have found these to be most effective when placed in areas that attract flies anyway: garbage cans, yard area where pets, etc. Because the fly population is overwhelming, these can't keep them all away but without them, the problem is much worse. Handle carefully, fill and place according to instructions, and they will fill with flies...nasty!
