Roof rat droppings are identified by their spindle shape, pointed ends, dark color (shiny black when fresh, gray when old), and size (around 1/2 inch or 12-18 mm long), unlike Norway rats with blunt ends or mice with smaller, more pointed droppings. They're often found in clusters along travel paths, near food sources in attics, behind appliances, or in cupboards, and are accompanied by a musky odor and greasy rub marks.
Roof rats produce droppings that are about ½ an inch long, black, and pointed at the ends. Many say that they resemble the shape of a curved sausage. Common brown rats are larger and produce larger droppings. They are typically longer than ½ an inch, oblong shaped, and blunt at both ends.
Signs of a Roof Rat Infestation
To address attic rodents, start by identifying entry points and sealing them with steel wool and caulk. Use snap traps baited with peanut butter placed along walls where droppings appear. Electronic traps offer quick kills without poisons. Ultrasonic repellents can supplement but aren't fully reliable alone.
Size, Shape, and Color. At first glance, rat droppings can be mistaken for mouse or even squirrel poop. They're all small, dark, and pellet-shaped. But a closer look shows clear differences.
Look for signs of rat or mouse infestation: Rodent droppings around food packages, in drawers or cupboards, and under the sink. Nesting material such as shredded paper, fabric, or dried plant matter. Signs of chewing on food packaging.
You might notice small, dark, droppings scattered around your attic or near entry points. Insects like cockroaches and termites also leave behind signs of their presence, though their droppings tend to be much smaller and harder to spot. If you see feces in your attic, it might be time to investigate further.
Rats are most active at night. Both Norway rats and Roof rats will venture from their nests to forage once the sun sets. During the day, they prefer to be in a dark and cool place. So, once daybreak nears, rats will retreat back to their nest.
In this situation, the best course of action is to contact a wildlife removal company to help. They have the expertise to handle these situations.
Use peppermint oil, ammonia, and citronella to deter rats. Apply these scents around entry points and nesting areas. Refresh scent barriers regularly for best results.
Nocturnal Activity
As soon as the sun goes down, roof rats start foraging for food and sometimes travel several hundred feet seeking food to eat and store. They like to hoard the food they find so that they can access it at any time. Roof rats prefer to eat in spots where they feel sheltered or hidden.
Your roof will usually have small gaps created by your roof corner intersection, which rats can usually fit through. They can also chew through ridge cap plugs to gain entry. Any gaps should be sealed with a waterproof sealant.
Rats and mice are the most notorious pests found in roof cavities. They are easily identifiable by their nightly activities of scratching, squeaking, chattering and gnawing. Since they're moody little creatures, the noises can often be loud and quite annoying!
Rat behaviour
One of the most common signs that rats have paid a visit is their faeces, which are dark and pellet-shaped, and look like large grains of rice. These tend to be clustered in certain areas, as rats often use the same spot to do their business and can leave up to 40 droppings in one night. It must be all that fibre!
SIGNS OF ROOF RATS
The best way to get rid of rats or mice is by using traps. If using spring loaded traps for rats, bait three of them in a row without setting them. Bait with dried fruit, peanut butter mixed with oats, or cheese.
Scratching noises typically result from rodents moving through loose insulation, burrowing within drywall cavities, or navigating wooden framing members. These sounds often indicate nest construction or expansion activities in wall voids, attics, and ceiling spaces.

5 Steps for Getting Rid of Roof Rats
Squeaking and scratching sounds are some of the most common signs that there are rats in the ceiling. If you're able to look in your attic or the space where the sounds are coming from, you may see these other signs. For example, you might find gnaw marks on wood or drywall.
Becoming sexually mature in a matter of months, roof rats typically have five to eight pups per litter and four to six litters per year. Though they will eat meat and grain, these adorable beasties love to feed on fresh fruit, plant materials, nuts, seeds, vegetables, tree bark and even bird feed.
Rabbit or goat droppings be mistaken for rat droppings, though they are usually more spherical (particularly rabbit) and uniform. Goat droppings may be more cylindrical but with flatter or round, rather than tapered ends.
Termite droppings (frass) can be a sign of an infestation. Drywood Termites push out frass through small holes in wood. Termite droppings are tiny, light brown to black pellets that look similar to sawdust or coffee grounds.
Three kinds of rodents are most commonly found in attics—squirrels, rats, and mice. These animals are all drawn to attics looking for dark, quiet, protected areas to nest and breed.
