With the loss of miles of habitat the adaptable pack rat is on a quest to find a new winter home. Unfortunately that brings them to our little green oasis and they dig their way under the back of our home. I set live traps and so far this year we have relocated 5 of them. They are destructive little rodents and will nest under hoods of vehicles using your wiring harness as nesting material. We keep our hoods propped open to keep them out as they like enclosed areas to make their nest.
