We have a rat infestation and the chickens are not even outside yet. Saw them while working on the tractor on the back patio, at least 3 large rats together, so I'm sure there are many more. I'm in the Indian Hills area east of Wasatch Blvd and 1700 South. There is a natural area behind the house up a gully. They have tunnels in the hill side behind our house. I put out bait two years ago into there holes and the dog got. I saw her and treated her immediately. I understand this is year 7 of a usual seven year cycle with rodent population on the high end. We have tried traps before but catch mostly birds and squirrel. The pellet gun is out, with limited successes. My 14 yo daughter is the only one that pick up the carcasses. Tried beer, I doubt that works. Have read about plaster of paris and peanut butter, but squirrels and birds will love that as well. So what you done that works?
BTW, I have 7, 2 1/2 week olds from 21st and the Draper IFA, so far so good. I did get them the day they came in.
