As their name implies, roof rats are arboreal and are more likely to infest higher structural areas, such as attics, soffits, drop ceilings and upper wall voids. They do very well in neighborhoods with mature landscaping - especially if it includes fruit and nut trees - and easily travel along fences, through trees, on utility lines and rooftops. Roof rats can rely on natural food sources and aren’t necessarily dependent on people for food.
The roof rat’s arboreal nature means management methods must be placed higher than usual for Norway rats. However, that doesn’t mean that efforts shouldn’t be made at ground level as roof rats will forage and sometimes dig burrows in dense vegetation. Snap traps should be placed along travel routes marked by gnawing, droppings or rub marks. Many roof rats can be caught by securing traps or stations to the utility conduits they travel. They’ll mostly be caught trying to bypass the traps.

Check out our Rodent Biology, Behavior and Management ProTraining course:
The commensal rodents are highly intelligent and adaptive pests that must be managed because of their ability to cause sickness and diseases. Understanding their behavior is the root of effective rodent management. After completing this course, you should be able to identify the commensal rodents and Peromyscus mice, recognize the diseases carried by pest rodents, understand how these rodents sense and navigate their environment and then recommend the proper management methods for each.
