STEP 1: Identify the roof rats and where they may be nesting.

It isn’t always clear what type of critter is scuttling in the walls or leaving droppings in the pantry. Like most rodents, roof rats are nocturnal and will mostly stay out of sight during the day. Because of this, it may also be unclear how many roof rats live together in the nest.

They tend to be darker and slightly smaller than their more common cousin, the brown rat. Another sign to look for are droppings. Roof rat droppings are much larger than mouse poop and are usually dark and shiny.

As soon as you spot these signs of roof rats, the next step is to locate their nest. Roof rats are adept at climbing and prefer to nest up high. It’s especially important to find out how to get rid of roof rats in the attic and other tough-to-reach spots—if the rats die up there or bring food back to the nest, this can lead to additional problems such as insects, mold, and unpleasant odors.

STEP 2: Block entryways to the home and trim any overhanging tree branches.

Once the nest has been located, homeowners can try to spot any gaps or holes where the rats could have gained entry and seal them with caulk.

It’s also a good idea to inspect the outside of the home for potential modes of entry. Since roof rats love heights, they may use tree branches or vines to make their way onto the roof.

STEP 3: Eliminate what may be attracting roof rats to your home.

Roof rats are opportunistic creatures—they’ll make their homes wherever they can find food, water, and shelter. Making these resources scarce in the home is absolutely essential to getting rid of roof rats. What do roof rats eat? In the wild, they prefer fruits, nuts, and seeds, but they are certainly not averse to “people food” if it’s accessible.

Homeowners will want to ensure that any food messes and crumbs are cleaned up every night and consider transferring pantry items to airtight containers. If they are hungry enough, rats will even snack on paper or cardboard, so dispose of any excess boxes or other clutter that rats may be able to access. It’s also a good idea to repair any leaks or areas with excess moisture.

STEP 4: Baiting and trapping can eliminate a roof rat population.

Baiting and trapping are tried and true methods of getting rid of rodents, including roof rats. Trapping is a good option for eliminating rats indoors. Snap traps or electronic traps marketed for rodents are all effective roof rat traps. Place a few of these near the nest or in places where roof rat poop or tracks have been spotted and check them a couple of times a day. Most types of traps can be emptied and reset for multiple uses. Rat bait, or rodenticide, contains poison that is strong enough to kill rats once they finish feeding on it.

STEP 5: Consider natural deterrents to discourage roof rats.

Homeowners who are wondering how to get rid of rats without poison, may prefer to use natural deterrents instead of rodenticide. This is a more humane method for how to get rid of rats in the attic naturally that eliminates the need for dangerous chemicals around the home.

Natural deterrents utilize scents or substances that roof rats find unpleasant to keep them away from the house. Mothballs, chili pepper flakes, garlic, and peppermint oil, clove oil, or tea tree oil are all effective deterrents that some homeowners may already have on hand. Homeowners can apply these substances in parts of the home or yard where roof rats have been spotted to discourage them from coming back. Ultrasonic devices are another natural alternative; they emit a high-pitched sound that repels roof rats and other rodents and pests.

STEP 6: Contact a pest control professional to get rid of roof rats.

If roof rats refuse to take the hint after a homeowner has all of the above steps, or if the infestation is severe, it may be wise to contact a roof rat exterminator. Roof rats can be particularly elusive because of their affinity for heights. Pest control professionals know how to get rid of rats in walls, ceilings, and other areas that are difficult to access.

Another major concern when dealing with roof rats is the potential for exposure to bacteria and viruses. Exterminators can safely dispose of any droppings or carcasses to mitigate the spread of disease. If the idea of dealing with the problem yourself is overwhelming, don’t hesitate to ask for professional help.

Using the above methods will likely rid the home of roof rats in short order. Remember that roof rats are intentional about where they make their nests, so eliminating anything that might have attracted them to your home in the first place will be a key component of this process.
