We have been using this fly tape for several years now. We live on a farm with cattle and goats so we have a lot of flies. We have them in each barn and lean too as well as our cattle cooler. The tape is sticky, catches the flies and can be wound up. We appreciate not using a chemical, we don't have the smell like other fly catchers do, we don't have to fly bomb and put chemicals into the air. The tape is not noticeable in our barns but really does help our livestock. It also has made a difference so that we don't have as many flies up around our house. When people come to our farm and are in our barns, my husband always points them out to other farmers. They end up getting them too and talk about the difference they make at their homestead as well. We have been very pleased with the product!
