Does Oahu Have Roof Rats That I Need to Worry about?

Coming in at about seven inches long with a tail that’s slightly longer, roof rats may appear cute on the surface, but these strong and quick climbers can wreak havoc on the structural integrity of your property. Not only can rats chew through structural elements of a home, but they can also bite through electrical wiring in ceilings and walls, posing a risk of fire.

If the damage they can cause to your home wasn’t enough, roof rats can also lead to health problems. These rodents can carry over ten types of diseases that can spread to humans, including leptospirosis, murine typhus, salmonellosis, and rat lungworm disease. You don’t need to come into direct contact with roof rats to be at risk of contracting these diseases; indirect contact with excreta also poses a risk.

So, does Oahu have roof rats that should concern you? In short, yes, but the risks are very small provided you eliminate the rat infestation promptly.
