Find Out What Critter Is Making the Scratching Noise Inside Your Wall

Becoming a homeowner means welcoming house problems with open arms and solving them. After all, you would not want to waste time eradicating such delicate issues. Some houses can be so problematic that you will witness other problems arising if you don't take necessary actions quickly.

This will become a domino effect, and we don't want that. One of the common house problems many homeowners face is disturbing noises. You will hear these disturbing noises from time to time in your house.

For example, you may hear rattling noises in your air conditioning or heating system. However, those typically arise due to technical issues. But what if you hear scratching noises within the walls of the house? Fear not; it won't be a ghost!

Typically, this scratching noise in wall is due to a rodent or critter infestation. If this noise continues a few nights longer, you will have a problem. Then, you will have to contact a critter control company and have the house inspected to find out the culprit.

But which critter can create these noises? Let's find out in detail:

Causes of Scratching Noise in Wall

Scratching in walls can be caused by many wildlife creatures. You may hear squeaking, thumping, slithering, or chirping along with scratching sounds. Usually, animals scratch when they want to build nests, walkaround, or store food.

Unfortunately, linking this sound to a particular critter isn't easy. The volume of scratching won't determine the size of the animal. However, some critters are more likely to be the culprit than others regarding the scratching noise in wall.

The most common critters to make these scratching noises are:

1. Squirrels

Squirrels can easily get trapped inside the house. When there are squirrels in walls, you will hear noises as squirrels are active during the daytime. So, you may hear disturbing noises in your waking hours if the house is squirrel infested.

Moreover, squirrels tend to move randomly, resulting in inconsistent sounds. Furthermore, you may also find squirrel droppings in your house. These droppings will be lighter in color than mouse or rat droppings.

2. Mice

Another common culprit that produces scratching noise in wall is mice. In fact, they are a common reason why noise ensues from the ceilings. Other than scratching noises, you will hear their skittering – light footsteps as they run around the house.

Another big giveaway is that you may hear chewing or gnawing sounds that indicate that your house is mouse infested. Typically, mice are more active at night. However, if they are looking for food, they will move about in daytime as well.

You will hear the mice in walls sound at day or nighttime. But it is most common when the house is quiet, and the mice feel safe and away from danger.

3. Rats

Like mice, rats can also be the reason behind the scratching noise in wall occur. They also chew on food packages and other items. So, when you see bite marks on packaging, be prepared for the possibility of rat infestation.

You will hear scratching noises at night as rats are more active at night. Moreover, rats tend to leave urine tracks no matter where they go. This urine smell can be intense. So, if you experience foul odors along with scratching noises, chances are you have a rat problem.

4. Raccoons

Although raccoons are large enough to sneak their way into your house, they can still slip through. The baby or small raccoons can easily make their way inside through gaps and get trapped in your attic or other places of your house.

Since raccoons are pretty larger than rats, mice, and squirrels, you will be hearing lots of noises and other sounds showing an animal in distress. With that said, it will be easier for you to find out which critter has infested your house.

5. Bats

Another reason for scratching noise in wall is bats. Like other rodents, bats can carry numerous diseases. However, the scariest prospect is that they can fly. Just like other animals, bats can make scratching noises in your attic or other places of the house.

However, remember that bats are relatively quiet. In fact, homeowners wouldn't even know that bats have infested their houses for years. But most likely, homeowners find out about their presence when they start falling behind the walls.

Juvenile bats tend to fall more often into the wall crevices when they initially learn how to move around. These nocturnal creatures usually make scratching noises at night. When they fall behind the wall, they become disoriented. And if they can’t fly, they will try to climb to get out while scratching on the walls.

What to Do When You Hear Scratching Noise in Wall?

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.

Even the sweet-looking raccoons can become aggressive. And although bats don’t bite unless provoked, the last thing you want to face is an injury. It is best not to trap these creatures yourself to keep yourself safe. Let the professionals do the work.

How to Keep These Unwanted Visitors Away?

After determining the animal or critter problem, you don’t want it to repeat. To put a full stop to future infestations, do the following:

  • Inspect your house for any holes or gaps that could welcome these pests. The critter control company will help identify these entry points for you to seal them.
  • Keep the gutters free of debris. Also, stop leaving scraps of food around the house.
