Hearing movement in your walls usually means pests like mice, rats, squirrels, or bats are seeking shelter, food, or nesting, causing scratching, scurrying, or squeaking sounds, often at night (rodents) or during the day (squirrels). It could also be insects (termites, ants) or even non-pest issues like loose pipes or wiring, so pay attention to the sound's timing and type to identify if it's an animal or structural issue.
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.
Call your landlord. If you own a home, either call an exterminator. Or diy it. That means finding out if these are squirrels, if there is a nest. If it is mice or rats or something else like a bird. Then generally go around and fill up any cracks in the exterior with steel wool or steel mesh.
Unlike mice or rats, cockroaches don't make noise. So, if you hear cockroaches inside your walls, you are mostly likely dealing with a severe infestation. They can also build their nest inside walls, if the conditions are favourable enough.
Examine Droppings: As unpleasant as it may be, the appearance of droppings can help identify the animal. Monitor Activity: Note when the noises are most frequent. Sounds in the wall at night usually indicate nocturnal animals like mice, rats, or raccoons.
What Are Signs of Rats in the Walls? Squeaking or scurrying sounds in the walls. Running or soft footsteps sound mainly during the night. Droppings in an area behind a stove, in the basement or attic, or on the ground.
Look for signs of rat or mouse infestation: Rodent droppings around food packages, in drawers or cupboards, and under the sink. Nesting material such as shredded paper, fabric, or dried plant matter. Signs of chewing on food packaging.
You shouldn't squish a cockroach because it spreads harmful bacteria, releases pheromones that attract more roaches, and creates a messy, smelly stain, potentially triggering allergies or asthma, with better, cleaner options like traps or professional pest control available for proper management.
Some cockroaches make noise through stridulation, as mentioned above, while others release air through respiratory openings to produce hissing sounds. The volume and intensity of these cockroach sounds can vary, but humans are capable of hearing them, especially at night when other noises are minimal.
While pouring bleach down the drain can kill roaches, it's a harsh chemical that can be harmful to your plumbing over time. Alternatively, many people turn to methods using baking soda and vinegar. This treatment, however, has no effect on cockroaches in the drain.
An infestation is often more extensive than it seems—mice are secretive dwellers, taking residence in wall voids to avoid detection while they nest and multiply. The duration of their stay can span from mere days to several months, depending on the accessibility of food sources and the level of safety they perceive.
What If You Hear Scratching in Walls But Can't Find Droppings or Other Warning Signs? Finding no droppings does not necessarily mean your home is pest-free. Some animals, like bats or certain insects, leave less noticeable traces, or their droppings might not make it into visible areas.
Sound #1: Light Scratching and Gnawing
The most common early indicator of mice in walls is light, intermittent scratching or gnawing sounds. You'll typically hear these during nighttime hours when mice are most active.
If they live in your walls, you may see trails between where rats live and their food source. Rats travel along baseboards and appliance edges and typically do not travel more than 50 feet for food. Other signs of rats in walls include noises coming from your walls. You may hear squeaks, chirps, or hisses.
If the sound you're hearing goes on all day, or doesn't sound like popping and cracking, you may have some repair work to do. If you're worried about a noise and you can't determine the cause, your first step should be to schedule a Home Maintenance Inspection.
Several types of insects will cause noise in walls. Carpenter ants, wasps, termites, and beetles are commonly found living in the relative seclusion of walls.
Though cockroaches are generally silent, in severe infestations, you may hear rustling or light scratching noises at night, particularly in wall cavities, under sinks, or within kitchen cabinets.
Roaches hate strong, pungent smells that disrupt their senses, like peppermint oil, eucalyptus, citronella, lavender, citrus (lemon/orange), bay leaves, and coffee grounds, with essential oils and spices being common deterrents that overpower their antennae, though these usually require professional extermination for serious infestations.
Here's how to attract a cockroach out of hiding: Use sticky traps or gel baits near warm, dark areas like behind the stove, under the fridge, or near drains. Using a bait or attractant is the best way to lure them out.
You can significantly reduce or eliminate roaches through a combination of extreme sanitation, moisture control, and effective treatments like baits, powders (boric acid/diatomaceous earth), and growth regulators, but 100% elimination, especially in large infestations or multi-unit buildings, often requires professional pest control because they reproduce rapidly and hide well. The key is denying them food, water, and shelter, using targeted products like gel baits to kill the colony, and sealing entry points.
Unfortunately, cockroaches are not loners. If you see one, there are likely many more that you can't see. Cockroaches are nocturnal creatures, so you'll most likely spot them late at night, especially if you walk into your kitchen and turn on the light.
As Lockwood explains, the things we find so repulsive about roaches are all a matter of those creatures' biology. “Cockroaches tap into this sort of evolutionary aversion we have to greasy, smelly, slimy things,” he says.
Wild rats are not used to human contact and will bite when handled or when people attempt to feed them by hand. The nocturnal creatures have also been known to bite sleeping people, particularly children and infants, on exposed body parts such as fingers, hands, toes and the face when foraging for food.
If there is a distinct and unpleasant smell in certain areas in your home or garden, you may have a rat problem. Rats have a particular smell and can leave a strong aroma from their urine. Usually, pets will sense this smell first and might become more active or unsettled in areas where the smell is coming from.
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.
