I have cotton rats in my greenhouses. They bite the spaghetti tubes and everything gets sprayed with water except the plant that the tube was in. I use the spring traps, but I only seem to have the clever rodents left. The Glue boards are probably the safest for the owls and hawks and my dogs, but.. I have a strange affinity for rodents, so I hate to see them suffer. But this may be my only recourse. The area I would need cover prohibits trying the fresh cab. It would be too expensive to replace every month. Have any of you used the Agrid 3?
