Easiest and most effective fly killer I've used
A friend recommended this to me and I used it last year. Decided that it was much easier, more effective and definitely less gross than tapes and jugs. Sprinkled it on paper plates and left them around the barn. Also made a paste with water and applied it to doorways where flys congregated. This stuff kills flies fast and easy. My barn cats leave it alone even though it's on the floor, they're not interested. It's pretty stinky, but not anywhere close to the jugs and so much easier to use, a little bit goes a long way - that's why I ordered the 5 gallon bucket, it'll last for years in my small barn and I don't have to make trips to the store to replace the little bottles.
