Often, squeaks or hisses signify that a rat is afraid or in pain. Almost all rat vocalizations are undetectable by the human ear because they are ultrasonic. The sounds of rats you will hear are movement noises. You can hear scratching, gnawing, and rustling in your attic or inside walls.
Rats are nocturnal animals, so you'll often hear them during the night. Rats will make chattering, squeaking, scattering and hissing sounds to communicate to others in their colony. Rats like to move around the same areas, which is why you will hear these sounds in one area of your home.
The most common noise is a high-pitched squeak or squeal, which is usually heard when rats are startled or in distress. This sound is created by vibrating membranes within the throat and is used to communicate alarm or fear.
Rat Sounds in Attic
Depending on their mood, these vocal pests make a variety of different sounds. Teeth chattering or clacking may indicate feelings of anxiety or contentment, while fighting rats can make a loud shrieking, hissing, or squeaking noise.
Scream or squeal
Generally it is uttered by a rat who does not know what to do in that situation and is completely lost in its fear and sees no way out of the situation.

Growling or grunting: Rats may growl or grunt when they feel threatened or aggressive. Screaming: Rats can make loud, high-pitched screams when they are in extreme distress or pain.
Rats are afraid of human activity, mostly because humans are so much larger than they are. Rats also fear predators such as hawks, eagles, and other birds of prey. Other animals that rats are afraid of include your cat as well as rat terriers and other dogs that hunt rodents. Rats fear becoming a meal for a snake.
Rats and rodents in general are very sensitive to sound, since it's one of their main tools for survival. Any new or unexpected noise will frighten them and send them scurrying. However, once rodents get used to a sound, they will no longer fear it.
So, for example, from the human audiogram you can see that people hear pretty well at 1,000Hz; here, the threshold of hearing is a scant 2 decibels. For rats, however, the threshold is more like 24dB. That means that a 20dB sound at 1,000Hz would be easily audible to you but would be entirely inaudible to the rodent.
Wheezing in rats sounds similar to wheezing in humans; it's a whistling noise in the breathing. While wheezing often does happen when your rat is rattling, they don't always go together. This noise is usually a symptom of a new respiratory infection, or sometimes it can be linked to a mycoplasma flare.
Both rats and mice are good climbers and can climb vertical walls and "shimmy" up between walls and drain pipes. Rats are also excellent swimmers and have been known to enter premises through the water traps of the toilet bowl when infestations occur in the main sewerage system.
One such signal that has the potential to attract rats is prosocial 50 kHz calls.
Rat sounds
Chirps and squeaks are common in mice, but rats tend to communicate at a pitch which is undetectable to humans. If a rat is afraid or in pain however, you may be able to hear squeaks or hissing sounds.
Mice and rats are nocturnal, so if they're in your home, you'll most likely hear their sounds at night or right as you're heading to bed. However, rodents aren't the only animals that may make or cause noise in your home. Sounds during the day may indicate a squirrel infestation, as these animals are diurnal.
The smell of peppermint, chili pepper, eucalyptus, citronella, and sagebrush are all effective at keeping rats away if applied in the right concentration. They are also deterred by chemical smells like ammonia and bleach.
Peppermint Oil
On a cotton ball use no more than 5 drops of 100% peppermint essential oil. Spread the oil on areas that you want rats to avoid, in your case, around the garden.
Electronic rat traps are considered the most modern and effective traps for rodents. These traps lure rodents with food and baits them onto a metal plate inside that immediately electrocutes them. It is the most humane approach in comparison to snap traps and poisonous traps – the rat's death is nearly instant.
If you have musophobia, you may experience extreme fear, panic or anxiety when you encounter mice or rats. Although many people will have reasonable fears and concerns relating to mice and rats, people with musophobia experience fear, anxiety and panic that is overwhelming and disproportionate to the risks.
These experiments establish that rats can communicate fear and induce specific odor fear learning via pheromone information.
Rats are generally not aggressive towards humans and will only attack if they feel threatened or cornered. However, there have been cases of rats biting people, especially children. Rat bites can be dangerous, as they can transmit diseases such as rabies, leptospirosis, and tetanus.
Loud Noises
What Do Rats Sound Like at Night? The most common noise a rat makes is a high-pitched squeak. This sound is often described as a “squeaky wheel” or “squeaky toy” sound.
When in fact rats do make a lot of noise, it's just at a frequency that we can't hear. Rats use these high frequency noises when they are stressed or frightened, and it's used to communicate the sound of discomfort or pain. Some rats will squeak or grunt when they're kept as pets and their owner talks to them.
As well as the noises they make scurrying across attics and gnawing on fixtures; they use various squeaking, hissing, and other sounds to communicate with one another. The reason they can seem pretty quiet to us is that many of these noises are at frequencies that human ears can't detect.
