Hearing what sounds like footsteps in your attic is most commonly caused by wildlife (such as raccoons or squirrels), rodents (mice or rats), or even the natural settling and expansion of your home’s wood and metal components as the temperature shifts.
Hearing footsteps or knocking above you is highly unsettling, but it’s rarely a person. The most common causes are nocturnal wildlife, temperature changes causing the roof to expand or contract, or settling building materials.
Strange sounds coming from above the ceiling can quickly raise concern for homeowners. Noises in the attic usually indicate that animals have found a way inside, using the space for nesting, movement, or shelter. Scratching, thumping, and gnawing sounds are commonly linked to rodents or wildlife activity.
Strange Sounds in the House: Footsteps
Just not a ghost. If you have an unfinished attic, odds are those footsteps you hear come from some rowdy ducks, mice, a cat or even a wily raccoon. Maybe they are looking for food or – perhaps – to escape from becoming food.
Signs of Roof Rats in Your Attic
Rats are highly nocturnal creatures. They typically leave the attic at dusk (around sundown) to forage for food and water, returning to their nests by daybreak.
Rats in the attic typically make scratching, scurrying, gnawing, and rustling sounds. Because they are nocturnal, these noises are most frequently heard at night, particularly between 10:00 PM and 4:00 AM. You may also occasionally hear squeaks or thumping as they run along rafters or chew through insulation.
The animal most likely in your attic depends on what you hear and when you hear it. The most common attic invaders are mice/rats, squirrels, raccoons, and bats.
Rats. What do rats in the loft sound like? You will be able to hear them scurrying across the floor at night or throughout the day; they also gnaw more loudly than mice. Rats will also find their way into most spaces and take shelter in cavity walls and loft insulation.
Wildlife Intruders
Animals such as bats, squirrels, raccoons, mice, and even birds can find their way into attics seeking shelter or food. These living creatures can create all kinds of attic sounds—scratching sounds, scurrying, thumps, and even bangs—depending on the animal and the time of day.
Mice do not sound extremely loud, but they can be surprisingly audible at night. Because mice are nocturnal, you will primarily hear them when the house is still.
Noises in lofts are commonly caused by pests, particularly in winter, including rodents (mice, rats, squirrels) scratching, chewing, or scurrying.
Hearing footsteps upstairs is highly common and usually results from structural settling, temperature changes causing materials to expand or contract, or household pests like rodents in an attic or wall cavity. If you live in a multi-unit building, it is often just your upstairs neighbor walking normally.
Rodents (Rats and Mice)
Rodents are among the most common pests to invade roofs and attics. Signs of Rodents in Your Roof: Scratching or scurrying sounds at night.
To tell if a roofer is lying, watch out for high-pressure sales, suspiciously low bids, and demands for large upfront cash payments. Honest roofers provide clear, detailed contracts and verifiable credentials. Always check their local license, avoid signing contingency agreements before fully committing, and get a second opinion.
Wildlife, especially larger critters, make louder thuds and more persistent heavy scratching noises that can sound like something is knocking on your walls or heavy footsteps on your ceiling. Squirrels can be extremely noisy and sound like a sugared-up toddlers racing around and knocking things over.
Roof rats are highly active year-round but see major activity spikes in the fall and early winter (September–November) and early spring. During these times, seasonal temperature drops and food scarcity drive them to forage, hoard food, and seek warm, elevated indoor shelters like attics.
A typical indoor rat infestation usually consists of 5 to 15 rats living in a single nest. Because they are social and tribal creatures, they rarely live completely alone. However, depending on food supply and nesting space, a colony can rapidly multiply into dozens or even hundreds if left unchecked.
To permanently keep rats out of your attic, you must make the space physically impenetrable. The most effective approach combines structural sealing, routine yard maintenance, and strategic trapping.
Rats will stay in an attic indefinitely—often for the duration of their natural 1 to 2-year lifespan—unless you actively force them out. Because attics offer warmth, nesting materials, and safety, rats view them as prime real estate and will keep returning.
Typical Animal in Attic Sounds
Many people report hearing scratching in the attic or behind walls. Common animals that scratch or gnaw include mice, rats, squirrels, and bats.
Exterminators widely agree that bed bugs are the hardest pest to get rid of. Their ability to hitchhike, resilience against over-the-counter pesticides, and talent for hiding in microscopic crevices make DIY eradication nearly impossible.
Look for signs of rat or mouse infestation:
Common nighttime rodent sounds include:
Persistent scratching noises within ceiling spaces or behind wall surfaces. Rhythmic gnawing sounds near baseboards, around plumbing fixtures, or electrical outlets. Rapid scurrying or running movements in attic areas, crawl spaces, or between floor levels.
The worst time for rats generally peaks in fall and winter, when dropping temperatures and scarcer outdoor food force them indoors to seek warmth and shelter. However, spring and summer are also highly active periods, as warm weather and abundant food trigger peak breeding cycles and rapid population growth.
