Other Names: Packrat, Traderat

Earning its nickname "packrat," this rodent is particularly fond of shiny objects and will drop whatever it's carrying to take the trinket instead. Woodrats gnaw on fruit trees, furniture, mattress bedding, wires, conduits and paper products in the home. They can cause serious financial loss for farmers and homeowners.

Identify Damage

Droppings | Gnaw Marks | Collection Habits

Droppings, gnaw marks, and urine odors are just a few signs of rat activity.


Droppings are the most commonly encountered evidence of rodent activity. Even a small rat infestation can produce literally thousands of droppings in a short period of time.

An adult rat typically produces 40 to 50 droppings per day. These fecal pellets are usually dark-colored, 1/2 inch in length, and oval shaped.

Gnaw Marks 

Evidence of recent gnawing is an excellent sign for determining the presence of Woodrats.

Rats tend to gnaw on wooden structures such as corners, floor joists, and wall studs. When Woodrats gnaw holes into cartons and boxes, the holes typically measure about 2 inches in diameter and contain rough, torn edges.

Collection Habits 

Woodrats are also called Packrats because they will collect various objects they encounter during their night forays. They are particularly attracted to shiny or bright objects. Thus, they collect pieces of glass, cans, mirrors, coins and jewelry.

Woodrats are also called "traderats" because of the stories associated with them stealing keys, wedding rings and such at campsites. Evidently, the rats will drop whatever they are carrying at the time they encounter a new "attractive" object.

In this manner, sticks have been traded for wedding rings and berries for car keys. It is important to note that this attraction to new objects is in sharp contrast to the fear of new objects of the Roof & Norway rats.
