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.
You might hear scratching and gnawing as they crawl around or chew on your walls and wires. You could also hear a scurrying noise as they move quickly across your attic. Chirps and squeaks are also common in mice, but rats usually communicate at a pitch that humans cannot hear.
Do rats make noise at night? 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.
Rats and mice are nocturnal with most activity taking place between approximately one half hour after sunset to about one half hour before sunrise.
Rats are nocturnal which means they're most active at night and during dawn and dusk. What's more, even though they can be brazen at times, they will generally do everything they can to avoid human contact. Typically, they will wait until it's very quiet before venturing out.
If rats are in your ceiling, you will likely want to contact a professional. Rats in your ceiling could indicate that they have built a nest and started reproducing. Unfortunately, these creatures are capable of reproducing at an alarming rate.
Rats will chew the ceiling once they detect a food source. Most ceilings are made of dry wood. Dry wood offers no resistance to the strong and hard teeth rats have.
Direct contact with a roof rat, dead or alive, puts people at risk for rat-bite fever. Bites and scratches are especially dangerous. Some roof rat diseases can also infect people indirectly. Fleas from diseased rodents spread typhus and plague.
Roof rats are prevalent in many parts of the U.S., including Southern California. The bad news is that roof rats can wreak havoc on your home if not appropriately eradicated.

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.
Placing deterrents on the roof such as mothballs, chili pepper flakes, or cotton balls dipped in peppermint oil or tea tree oil will discourage rats from entering the home. Ultrasonic devices may also be effective for deterring rats and other common pests.
A roof rat spends most of the day sleeping in its nest. These rodents are nimble climbers and live in high places like attics or above drop ceilings. If residents notice a roof rat during the day, it could point to the presence of a larger population just out of sight.

Failing to report a rat infestation is not wise – they do not disappear of their own accord and they will likely spread.
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 are the most common culprit if you are hearing a scratching noise in your ceiling or walls. Few sounds are as unsettling as when you hear a scratching noise in the ceiling at night.
