Most often, it's your home's plumbing system. Sometimes it's due to fluctuating water pressure issues, loose plumbing pipes, or a faulty valve.
While water hammer is the most common cause of a loud banging noise, it may also relate to loose straps connecting the pipes to the wall studs of the house. The loose straps may relate to water hammer or be due to other factors. The problem may also stem from excessive water pressure in your house.
Knocking sounds during the night are probably coming from a large animal like a raccoon or opossum. High-pitched chirping in the house is likely coming from birds. Birds like to nest in the attic after making their way through soffits and attic vents.
Tapping, rustling, or clicking within the walls of your home can be the first indicators of some gruesome pests taking hold of your property. Things like termites or carpenter ants are often to blame for tapping noises. These pests make these noises whilst they hollow into the wood and make nests.
If you hear any clicking, buzzing or tapping sounds in the wall, you may be facing a potential termite invasion. Termites are hard to spot and often go unnoticed, causing significant amounts of damage in homes each year.
What Is Pulsatile Tinnitus? People with pulsatile tinnitus often hear rhythmic thumping, whooshing or throbbing in one or both ears. Some patients report the sounds as annoying. But for others, the sounds are intense and debilitating, making it difficult to concentrate or sleep.
The most commonly heard call of the Large-tailed Nightjar is a monotonous series of hollow “chonk, chonk, chonk…” notes which sound a bit like a distant chopping or knocking on wood. These sounds are most frequently given just after dusk or just before dawn.
One issue we run into a lot is the mysterious tapping sound whenever a fixture is running water. This sound usually indicates that there is a water leak either in the ceiling or in the wall.
The many materials that make up your house — wood framing, plywood, glass, metal ducts, nails, plumbing pipes — all expand and contract at different rates. When a house cools at night, these materials may move slightly, rubbing against each other and making noises. Occasionally, they'll contract with an audible pop.
If you have heard scratching noises in the walls of your house but haven't yet seen any critters, the best thing to do is call a Critter Removal company. The professionals will come out and inspect your house. Remember that although these critters may look harmless, like mice, they can host multiple diseases.
Look at the sliding doors (if there are any) and objects stored outside that might rock against the house such as a gas grill, loose siding or aluminum trim, a light fixture, an old aluminum awning, or a loose shutter. Also consider that what you're hearing may not be something loose but a corner that catches the wind.
Signs That Animals Are in Your Walls
Mice and rats are nocturnal, so you'll most likely hear scratching in walls once the sun has set and the house has quieted down. Squirrels, on the other hand, are diurnal, meaning they're awake and active during the day.
Often burglars will knock on the door to case out your home and see if anyone is there. If you go to the door, they'll pretend to be offering a service such as lawn mowing or tree trimming. If no one comes to the door – they often break in and burglarize your house.
Buildup of Carbon Deposits
Commonly, engine knocking occurs because of a buildup of oily carbon deposits inside the combustion chamber. This can be caused by burning oil or incomplete combustion from misfires, which coats pistons, cylinder heads, and other parts of your engine with residue.
If you hear scratching in your walls at night, it could be mice, rats, squirrels, raccoons, bats, termites, carpenter ants, or roach colonies. By far, the most common nighttime wall-scratchers are mice, and they're most likely the pests who are disturbing your sleep.

Rats, mice, squirrels, raccoons, skunks, bats, opossums, and birds are among the most common culprits in this kind of situation. Scratching noises coming from your walls or ceiling is a solid indicator that an animal has made its way into your house. It could be a wild critter trapped inside, unable to get out.
Once you have convinced there is nothing actually in your ear, you need to realize that a ticking sound may come from the inner ear, as tinnitus, or a ringing in the ear, can take many forms. Some people commonly hear it as a high pitched ringing sound, but others can get a “crickets chirping” type of effect.
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.
While people can sometimes pick up the sound of rats squeaking in walls, it is more common to notice louder, more repetitive activities. These typically include rustling or scratching noises in the wall when the pests run, as well as thumping sounds that occur when they bump surfaces.
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.
Hammering can be caused by waterlogged air chambers, clogged chambers, or excess pressure in your plumbing system. It can also be the result of a valve or pipe clog, which can produce a staccato banging sound.
This is because mice can live for months without water, as they'll often get what they need through condensation on pipes in your walls. Without food, however, they can live as much as a week, or possibly two.
