The Problem With Roof Rats

Roof Rats...

• Are elusive and nocturnal
• Are difficult to remove once they've established their territory
• Have a high production rate
• Are very destructive
• Can be undetected in vacant properties

Indicators of Roof Rats

Number one indicator: Hollowed-out fruit that is still hanging on the tree

Look out for:

• Sounds. Squeaks, gnawing, clawing, and scrambling in walls
• Droppings. Roof rat droppings are 1/2“ in length 
• Nests. Often visible in attics, or when vegetation is trimmed
• Smudge marks. Oil and grease that rub off a rat's fur build up on well-used runways
• Hollow fruit. Located still hanging on the tree

Pay attention to:

• Tracks. Adult footprint is 3/4" long 
• Gnawing. Rats constantly gnaw on hard surfaces. Gnawed holes may be 2" or more in diameter
• Food caches. Rats may store surprisingly large quantities of food in protected areas
• Pet excitement. Cats and dogs often probe an area where rats are active
• Odor. Heavy infestations have a distinctive odor
