Name: Pack Rat (
Neotoma albigula - White-throated wood rat)
Size: up to 15" and 8 oz.
Their nests, or middens, consists of piles of branches, plant material, trash, etc. The dens are then fortified with cactus, particularly cholla. They are known for collecting objects to place in their den. They like shiny objects and will be more than happy to take your watch or jewelry to their den. Mine seem to like taking dog droppings to their nest. Pack rats are also quite happy with eating your landscape plants getting their water from succulents and cacti. They must have shelter to survive and will die with exposure to heat, cold or direct sunlight.
The same pack rat midden may be used for centuries and have provided a valuable resource for paleobotanist and paleoentomologists and well as regular paleontologists, after all a man made piece stolen centuries ago could be in the nest.
I will reiterate the first post: They are VERY DESTRUCTIVE to your house and personal property. If your house is surrounded by natural desert they are an unavoidable inconvenience.
