There is a pond 40 yards from the back of our house, and I don't want to kill the fish. I don't want to kill my little Dachshunds. I don't want to kill anything but bugs. The pond has frightened me away from the products I've seen in the local home improvement warehouses. I don't know if the pond is far enough away to be safe from perimeter sprays. I imagine the rain could carry the chemicals to the pond. But I want something that really works, and will knock back ants, pill bugs, roaches, and spiders. Did I mention I don't want my doggies to get sick stepping across these perimeters? Surely someone out there is in a similar situation and can recommend something? Please?
