Please be aware that the use of this product may get you in trouble as well. Although it does work well for preditors, it may not be legal to use it in your area. The fly bait mentioned is Golden Malrin which is a neural toxin designed to control flys in a dairy or fly infested area. The neural toxin in Golden Malrin shuts down all brain functions in the flies resulting in death. This is what the product was designed for. Regardless of application, it DOES kill anything that ingests it. As for Chickenzoo's comments that there is no suffering never saw the animal after eating the bait. He just saw the results. I have seen it. I would recommend all alternative methods before using this. It does get rid of your preditors but Please read the lable for usage of this product. " Use of this product other than intended use may be unlawful..." Just cover your own butt if you decide to use this method.
