roof rat
Arboreal house rodent
A roof rat is a common rat species that tends to nest in elevated locations—attics, rafters, trees, and dense vegetation—rather than in burrows like the Norway rat.
Roof rats are slender with long tails, excellent climbers, and widespread in warmer climates.
They're significant agricultural pests and disease vectors: The inspector found roof rat droppings in the attic.
