It does work. I’m in sales...have been in lots of open businesses...first time I saw the plastic bags containing water hung throughout an establishment was in Anahuac, Texas in the local beer joint. I ask why...they explained the fly thingy [they got it from local horse stables...I understand that's where it started]...I had a place where I continued to have fly problems...so I tried it...it took about 1 to 2 weeks...then one day I noticed NO FLIES...it’s got to be done a certain way...my Dad tried it in his restaurant...they didn’t do it right so it didn’t work...

they didn’t do it right so it didn’t work...

What did they do wrong? How do you do it right?
