Rats and mice love to move into attics and roofs. Not only do they get shelter, but they also get easy access to food and water in your home. Getting rid of them is a two-step process. First, you need to close up access points to ensure more of them cannot get inside.
It's likely a rat or mouse. Soon after sundown, it is not uncommon to hear the scurrying of rats and mice in the ceiling or wall cavities. Instead of clawing or squeaking, you'll probably only hear them racing and scampering.
Rats and Mice: Light running noises across the ceiling or walls, most frequently at night; sounds can range from barely audible to loud depending on the structure of the home. Raccoons: Heavy thumping and walking, crying chatter and sometimes scratching throughout the night.
SQUIRRELS IN THE ATTIC
Squirrels are most active in the morning and evening, so most people report hearing the sounds at that time. Squirrels are fast and light, so much of the noise sounds like fast scurrying or running, usually in the attic, near the edge of the roof, and sometimes noise in the walls or chimney.
As possums are nocturnal they generally move around at night. They have a heavy thumping movement across a roof or ceiling (described by some as sounding like an elephant walking on the roof!). Possums also cough and make hissing noises. Rats make a pitter patter sound on the roof or ceiling when moving about.
Rat Sounds in Attic
These nocturnal pests typically enter homes through basements, subfloors, and hollow walls, though some species, such as roof rats, are particularly common in the attic. Noises at night, such as gnawing, clawing, scratching, or squeaking, are usually the result of rats communicating with each other.
Rats make noises which may occur when they are excited, or leaping from one spot to another within the roof space. You may even hear loud thuds at times as the rats land on the ceiling and scamper around. The disturbance is louder in roof spaces that do not have insulation.
If you hear running at night, it is likely nocturnal animals like rats, squirrels, or raccoons. When squirrels are in the attic, they are mostly heard during the day.
Probably the number one concern is that the scrabbling sound you hear is a rodent. Rats and mice love to move into attics and roofs. Not only do they get shelter, but they also get easy access to food and water in your home. Getting rid of them is a two-step process.
Native Animals That Are Most Likely To Live In Your Roof Cavity. In Australia, roof cavities and voids provide conducive environments for rats and mice, possums and pest birds to live in. This is because most of their natural habitats have been cleared for development and farming.
I find that the most effective method to catch and remove animals is to seal off all of the entry points, down to the primary opening, and use live traps to trap the remaining animals inside.
Rodents in roofs
Lacking in that possum-like Australian charm are the familiar rodents including rats and mice. And no one has the time of day for these unwanted pests, especially if they're the culprits of the scratching noise in roof spaces at your home or business.
Amplified by an unfinished attic space, a raccoon or even a good-size squirrel on your roof might sound like an ax murderer is doing the polka overhead. These rooftop transits are normal for critters — roofs offer a nice long unobstructed highway.
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.
If you are hearing scratching noises specifically, as well as scurrying sounds. Mice or rats are your likely culprit. With rodents, you'll usually hear them around bedtime and late at night. Occasionally when the house is very quiet you will hear them during the day as well.
A repetitive ticking or clicking sound coming from walls and ceilings can result from the expansion and contraction of metal HVAC ductwork that conducts ventilation through these voids. When metal heats up, it expands; when the furnace stops pushing warm air through the system, the metal cools and contracts.
Being nocturnal, possums are generally most active at night. The usual signs of having a possum in the roof are heavy bangs on the ceiling or roof at night as they run around, hissing and coughing noises coming from your roof, or stains on your ceiling or a strong ammonia smell caused by their urine.
The first thing that homeowners usually notice is noises in the roof. Other signs are loss of power to some equipment due to chewed cables, marks on the ceiling from animal urine, or movement of downlights caused by animals sitting atop the lights. All these signs could be caused by either rodents or possums.
If you hear nighttime noises that sound like something is moving really fast, it could be rats or mice. In this case, you may hear them not only in the attic, but but also inside the walls. Although these rodents are quite small, they can make some noise.

Look at photos of Raccoon Feces, or Squirrel Feces, or Rat Feces, or Mouse Feces, or Bat Feces. You can also look at the animal tracks left in the dust in the attic. Check on almost any surface not covered by insulation, and there should be a layer of dust with animal tracks. Or you can check for muddy footprints.
Rats and mice are nocturnal with most activity taking place between approximately one half hour after sunset to about one half hour before sunrise.
