Why does it sound like someone's walking in my attic?
If you hear it at night primarily, it is either mice, raccoons, bats or (in some cases) a flying squirrel. If during the day, do you hear running around and “rolling” sounds? Squirrels will often be heard “rolling” nuts or other debris around in the attic during the day. Their movement is also very fast.
Is it normal to hear noises in the attic?
If you hear sounds during the day, it is most likely a squirrel or snake, although it can also be a raccoon. If the noises are at night, it is probably a raccoon, rodent, opossum, or snake. Noises at sunset will typically indicate bats. If you hear knocking noises in the attic, it could be several different species.
What does a squirrel sound like in the attic?
Scurrying noises – Light running and scratching noises across your attic floor are a good signifier that a squirrel has gained entry to your attic and is maneuvering back and forth. Rolling sounds – Squirrels collect nuts, acorns, and other small items.
Raccoons are nocturnal animals meaning you will usually hear them at night. Sounds like a slow walking, sliding or shifting are typical raccoon in attic noises. Fast running or jumping is very rare for a raccoon in the attic but could be the result of a territorial dispute or mating.
Loud Scratching Noises
As opossums nest, they make lots of ripping, scuttling, and scratching noises. These noises can sound similar to rats or mice, but you will likely notice that the noises seem louder because they're created by a bigger animal.
If you're hearing thumping noises, it's one of the surefire signs you have a raccoon in the attic. No other urban pest is big enough to create stomping noises. Squirrels will scurry and bang around, but a raccoon literally will sound like a small person is in there.
If it's a large hole with damage, like a torn open roof or a busted eave, that's a raccoon! If it's a hole maybe 2 inches in diameter with chewing around the perimeter, that's squirrel. If it's small gaps, perhaps with brown grease, that's rats or mice.
Scratching Sounds - Scratching and gnawing sounds may indicate a rodent type animal such as a mouse, rat or squirrel. Flapping - Flapping sounds can indicate birds have nested in your attic, birds will be most active in early morning.
Bats can sometimes be heard from inside walls and attics. Vocalizations in the form of chirping and squeaking as well as scratching, shuffling and scurrying could indicate bat activity. Bats are nocturnal, so expect to hear most noises at dusk and dawn.
Scratching. Another very common sound that mice make is scratching. As mice climb and crawl around your walls, ceiling and attics you will hear a scratching sound. They are also constantly scratching around for nesting materials.
Live trapping is the most humane and effective way to remove animals; however, it's almost impossible for a homeowner to successfully remove a large infestation of rodents or bats. As soon as you're aware of any animal present, act quickly to remove it before its population grows.
Noises such as scampering, scratching, or squeaking are sure signs that something is up there in your attic. The time of day will help give clues as to what type of animal it is. For example, mice and rats tend to move more at night while squirrels are active during the daytime hours.
If you have mice living in your attic, it is likely that they are traveling down through your wall voids to access areas of your home that have food or water sources. This is the noise you'll hear: scraping, scrambling, bumping, thumping, and sometimes, squeaking.
Raccoons have little “hands” and can grasp and are able to lift tiles up if they want to. Drywall ceilings are somewhat stronger than drop ceilings, but I never trust them when I am inspecting an attic. Their strength is dependent, to a great extent, on the quality of the workmanship that went into installing them.
However, they are capable of living up to around 20 years in captivity. Therefore, if you have raccoons living comfortably in your attic, you may have housemates for a long time without professional removal.
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.
Rats make a combination of squeaking, hissing, and chattering sounds. They can communicate different emotions depending on the frequency of the noise. Often, squeaks or hisses signify that a rat is afraid or in pain. The pests also chomp and grind their teeth.
Opossums will den anywhere they can find a spot that's dry, sheltered, and safe which is why they are commonly found living inside of attics and crawlspaces or underneath sheds and decks of both homes and businesses.
The North American opossum makes a hissing sound or a low growl when threatened or angry and a clicking sound to attract attention from their young. Young opossums often making a sneezing sound. Opossums are usually silent so if you hear them in your house then there is usually more than one.
Additionally, raccoons are primarily nocturnal, so the noises occur at night. Most of the noise might happen shortly after dusk, when the animal leaves the attic, and again sometime in the night when it returns. However, the timing of the noise may vary, and sometimes raccoons will stir during the daytime.
Raccoons that live in attics may be active during the day. You may also see the mother leave the house during the day to go off in search of food. Raccoons may leave urine and droppings throughout the attic. If you go in the attic and see and smell waste, this is a clear sign that you have raccoons living there.
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.
Mice are nocturnal animals so if there are squeaking and chewing noises at night, you might be dealing with these rodents. But if there are scurrying noises in broad daylight, then there's a good chance that the rodents in the attic are squirrels.
The most common attic pests are racoons, squirrels, bats, birds and mice.
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.
Rats are larger than mice and will have coarse red, brown, grey, or black fur (depending on the variety) and a long, scaly, fur-less tail. A mature rat can range from 11-19 inches long (including its tail) and weigh ½ to 1 pound. Mice have large ears and tiny black eyes.
If you're concerned about noises in your attic late at night, it's not likely to be a squirrel. Squirrels qualify as crepuscular animals, meaning they become most active during the evening and early morning hours. During the night, squirrels will settle down and spend the night resting in their den.
Squirrels will leave the attic during the warmer parts of the day. Attics get hot quickly, and become too hot during the Summer. Cooler Temperatures = More Noise During cooler seasons, you may report hearing much more noise. Scurrying, Scratching and Chewing are the most common noises.
The top signs that bats are in your house are:
Bats sound a lot like mice scratching. You will generally hear bats late at night and real early in the morning. Sometimes you will hear a lite flapping of their wings if the bats are trying to move through insulation. Bats will also make a chirping noise which is high pitched.
You can also identify bats through the noise they make. Whilst bats tend to be extremely quiet as they communicate through sonar, you may hear a chattering sound that they make, which is like a high pitched squeaking and scratching sound.
