Hearing movement in your walls is almost always caused by wildlife, rodents, or insects using your wall cavities for shelter or food. The type of pest often aligns with the time of day and the nature of the sound.
Squirrels: Squirrels make scratching and scurrying sounds that are similar to rats and mice. The biggest difference is that squirrels are diurnal (active during the day). So, ask yourself when the sounds are most pervasive. If during the day, you might have squirrels in your walls.
To determine what animal is in your wall, identify the time of day the sounds occur, listen to the type of noises (scratching vs. thumping), and check for physical clues like droppings, chew marks, or entry points around the exterior of your home.
Signs of rats in your walls, attic, and home
Mice in your walls typically make light, rapid scratching, scampering, and gnawing sounds. Because mice are nocturnal, you are most likely to hear these unsettling, rhythmic pattering noises at night when the house is quiet.
Do these 3 things to get mice out of walls:
It's a sound that can send a shiver down your spine – a faint scratching, a mysterious rustling, or a sudden squeak coming from within your walls.
Scaring mice out of walls requires driving them out of their nesting spots while simultaneously cutting off their ability to return. The most effective approach is a step-by-step strategy: irritate their senses to force them out, trap the remaining mice, and seal the wall voids permanently.
Look for signs of rat or mouse infestation:
Sign #1: Scratching and Scurrying Sounds at Night
You hear it when the house is quiet – usually between 10 PM and 4 AM. Scratching, scurrying, sometimes what sounds like chewing. What it means: Mice are crepuscular and nocturnal, most active at dusk and during the night.
Mice are capable of fitting through extremely small openings in floors, walls, and foundations. After they enter homes, they can be extremely difficult to get rid of. Mice living within walls rarely leave their nests during daylight.
Rats are most active between dusk and dawn, when you may hear scurrying, rustling or possibly scratching sounds in lofts, under floorboards or inside walls.
Animals in walls generally sound like scratching, scurrying, gnawing, or thumping, with the exact noise depending on the species. Smaller critters like mice produce light, rapid scratching at night, while larger animals like raccoons create heavier thuds, rustling, and vocalizations.
Mice and rats commonly seek refuge in the cozy spaces in walls of your home. This is the most common place you will hear their quick light tapping and scratching sounds. FYI - walls act as a hidden highway system for them to move unseen through out a home.
One of the most active times for rats is during autumn due to their preparation for the cold weather ahead. Rats become more active in September-November as they scavenge for food to stockpile and make nests. When temperatures start to drop, rats are less likely to venture out during daylight hours.
To get rid of rats in your walls fast, avoid using poison, which can cause dead rodents to decompose in hard-to-reach areas. Instead, place baited snap traps near baseboards, access holes, or where you hear scratching, and completely seal all exterior entry points using steel wool and caulk.
Live or Dead Rats: Seeing rats during daylight hours signals a significant population. Rat Droppings: Dark, pellet-like droppings in hidden areas. Grease Marks: Oily smudges along walls and baseboards. Gnaw Marks: Large, rough teeth marks on wood, plastic, and other materials.
Pest control experts widely consider bed bugs to be the absolute hardest infestation to eliminate. Their flat bodies allow them to hide in microscopic crevices, they can survive for months without feeding, and their presence is easily reintroduced through daily human movement.
But there are signs to watch out for including: Droppings and urine stains Burrows, holes or nests Runs and tracks Greasy rub marks and chew marks Chewed food packages Noises Rats and mice can cause property damage and health problems.
Seeing two mice doesn't automatically mean you have a full-blown infestation, but it is a strong warning sign. It typically indicates the beginning of a problem or suggests that a small family group is living nearby.
The 5-day mouse rule is a simple way to gauge whether your trapping efforts have worked. In short, if you've set traps and go about 5 to 7 days without catching anything—or seeing any signs of activity—there's a good chance the mice inside your home have been cleared out. Mice are constantly searching for food.
Hearing mice in your walls means you likely have an active infestation. To act fast, do not seal any holes yet. Instead, set snap traps in high-traffic areas outside the walls, cut off all food sources, and eventually seal all exterior entry points with caulk and steel wool.
Here's the reality: if you see one mouse during the day, there are likely 5-10 more you're not seeing. In other words, daytime sightings almost always indicate multiple mice. Even nighttime sightings suggest more than one. Mice are social animals that live in family groups.
You may hear mice scurrying around inside your walls and ceiling. Mice are especially active at night, so if you hear squeaking, skittering, or gnawing noises coming from inside the walls at bedtime, this could be a sure sign that mice have taken up residence.
Exterminators get rid of mice in walls by combining three methods: they use strategic traps where the mice emerge, place safe rodenticides in hidden cavities, and seal the structural entry points. This integrated approach forces the mice to abandon wall voids and prevents future infestations.
