One of the most common animals, squirrels are easily recognizable as they scurry through your yard. There are three major types: tree, ground, and flying squirrels, though common species differ regionally. The most common nuisance squirrel is the tree squirrel.

How to Identify a Squirrel Problem

Squirrels can make a wide range of vocalizations. Depending on their activity, you may hear a squirrel producing a high-pitched chirp when they get excited. They also bark when they feel threatened and whistle when they feel happy. To communicate with other squirrels, they make chattering noises.

How do I know if squirrels are in my attic?

You will hear squirrels in the attic. Squirrels are very active in the morning and at dusk. They leave their nest every day to forage for food. You’ll hear scampering, running, and scratching as they move through your attic or climb up and down inside the walls.

Do squirrels make noises on the roof?

Yes, squirrels make noises on your roof. Typical squirrel sounds also occur when the pests walk across rooftops, construct their dens, or attempt to gain entry through holes or other small openings that lead to attractive nesting sites.

What does a squirrel sound like?

Squirrels are noisy! They make different vocalizations. If you have a squirrel in the attic, you will hear sounds like scratching, rustling, scampering, gnawing, or scurrying.

Do squirrels make noises at night?

Generally no. You’re most likely to hear squirrel noises in the morning and at dusk because the animals are diurnal.

What do baby squirrels sound like?

When stressed or hungry, baby squirrels sound like young birds due to their soft, high-pitched chirping.

Are squirrels dangerous?

If you find squirrels in your attic, they’re more likely to run away than attack. That doesn’t mean they aren’t dangerous. Squirrels can spread diseases, contaminate attic insulation, and damage the physical structure of your home.

Are squirrels nocturnal?

No, squirrels are diurnal, meaning they are active during the day. If you hear sounds at night, it’s probably rats, mice, or raccoons.

Where do squirrels live?

The U.S. is home to over 20 different squirrel species. Tree squirrels, like the Eastern Gray squirrel, will look for safe places to nest off the ground, and they will nest in chimneys and attics.

Squirrel Appearance

  • 12-25 Inches in Length
  • Short, dense fur
  • Fur colors: black, brown, gray, red
  • Large bushy tails
  • Large, round eyes on the side of the head

How Squirrels Get Inside

While most people are familiar with a squirrel’s physical description, you may not realize how much of their anatomy makes them an ideal home invader.

Teeth

Like other rodents, squirrels have four incisors that continue to grow throughout their lives. They must gnaw to keep them at a manageable length. Squirrels will use these teeth to chew through wood, siding, and plastic and aluminum vents, allowing them to break into homes. Once inside your home, they’ll use their teeth to chew rafters and even electrical wires.

Tails

Squirrels use their tails primarily for balance. This allows them to balance and walk along utility wires or narrow tree branches to get to your roof.

Claws

While their teeth might start or widen the hole into your attic, they then use their claws to widen the opening enough to pass inside. The goal for them is to create an opening three to four inches wide, allowing them to comfortably come and go from your attic.

Ankles

This might seem like an odd body part to mention. However, squirrels have unique hind ankles. They can rotate their ankles by 180 degrees. On trees, it allows them to descend headfirst while their hind feet grip the bark. On a roof, this feature gives them tremendous dexterity. They can dig their claws into shingles and siding and hang upside down from eaves and gutters.

Eyes

Squirrels have excellent eyesight. Their eyes are positioned high on the sides of their head, giving them a panoramic view of the world. The 280-degree field of view enables them to quickly scan an entire roof when searching for a vulnerable spot to gain access to your home.

How to Identify Squirrels by Behavior

Squirrel behavior is unique. Highly active and energetic, they are diurnal rather than nocturnal like most other rodents. They are also highly intelligent and are capable of complex problem-solving. Behaviors such as tail-flicking, chattering, and their zigzagging movements all help in their identification.

A squirrel’s intelligence has informed them that a home’s attic is far superior to the leaf dreys (a tree squirrel’s nest) they usually build for refuge and to raise their young, especially in winter. Squirrels have learned that homes offer protection from predators and warmth from the cold of winter and the heat of summer. In their natural habitat, their dreys offer only partial protection from predators. In winter, they freeze, and in spring, they get waterlogged from rain.

How Squirrels Use Your Home

A squirrel uses a home differently than other home invaders because of their innate behavior. Similar to other species, they look for a safe place to raise their young, out of extreme weather and away from predators. And like others, they will tear insulation, papers, cardboard, fabric, and other soft belongings you have in storage to create their nest.

But unlike other pests such as rats and mice, squirrels will leave to forage for food as opposed to eating what’s in your pantry. They might even just use your attic to store nuts for winter.

Why You Need Critter Control

While in your attic, squirrels will not only make a racket with their thumping and chattering, but will also create costly damage to your home. And, they bring with them parasites and diseases that can be transmitted to you, your family, and your pets.

They create a fire hazard when chewing on electrical wires, and they weaken the structure of your home when gnawing on rafters, which can cost homeowners millions in repairs annually. Key diseases they carry include leptospirosis, salmonella, tularemia, and rabies. They also spread parasites such as ticks, fleas, and mites.

Critter Control has over 40 years of experience in humane and safe squirrel removal. We also take steps to seal all vulnerabilities to help prevent reinfestation, and we will sanitize the infested area.

Squirrels can make a wide range of vocalizations. Depending on their activity, you may hear a squirrel producing a high-pitched chirp when they get excited. They also bark when they feel threatened and whistle when they feel happy. To communicate with other squirrels, they make chattering noises.

    • Eastern gray squirrels are specifically known for their chattering.

    • Red squirrels also chatter, but their chatter is high-pitched.

    • Fox squirrels are different in that their vocalizations are lower-pitched.

What Movement Noises Do Squirrels Make?

Squirrels chew and gnaw on electrical wires, wood beams, drywall, siding, shingles, and plastic. If you hear noises in your attic, walls, or ceiling, it could be due to a squirrel. Movement noises to listen for include the patter of feet, running, scurrying, shuffling, scratching, and tapping.

All the noises will be amplified if multiple squirrels live in your home. One squirrel running across the floor will be a light sound, but five squirrels running may sound more like galloping.

Squirrel Noises in the Attic

Depending on how many there are, you may hear multiple squirrel sounds in the attic, including the following:

    • Scratching on drywall, insulation, ducts, vents, and wood beams

    • Crumpling of paper or other materials being stored in the attic

    • Acorns and other nuts roll across the floor

    • Dragging of nesting materials

    • Digging in one spot, like insulation or drywall

Squirrel Noises in the Walls

Scurrying is the most common noise you will hear from squirrels. Other squirrel sounds in walls include tapping, chewing, gnawing, and scratching. You may also hear a squirrel build or add to its nest, including crumpling or breaking twigs, papers, and leaves.

Squirrel Noises on the Roof

Squirrel sounds on the roof vary depending on the task it is working on. They spend a lot of time on the roof, running back and forth, bringing their day’s findings to various hiding spots. They jump from trees to the roof, run up the side of your home, or jump from electrical lines hanging above your roof.

Comparing Sounds in the House

Knowing the various sounds a squirrel makes is essential to understanding its actions. Below are the most common noises a squirrel makes:

    • Chatter sounds like clicking and squeaking, signaling that squirrels are communicating.

    • Squirrels use high-pitched screams or screeches to alert other squirrels of danger.

    • Deep, guttural barks are a squirrel’s way of protecting their territory but may also be part of a mating ritual.

    • Mating calls are not just barks; they may also include trills and whistles and can sound musical.

Squirrel Signs vs. Rat Sounds

Squirrels and rats make similar noises. It can be difficult to distinguish them by sound alone.

Squirrels are most active in the early mornings and late evenings. Rats are most active at night or when the home is quiet.

They are rodents and like to gnaw, chew, scratch, and scurry. Rats and squirrels build nests in attics, walls, and ceilings, but rats will enter other parts of your home. For example, rats get into pantries, pet food bags, trash cans, and anywhere else they can find food. It is likely a rat if you hear noises coming from those areas.

Squirrel Sounds vs. Raccoon Sounds

Raccoons are much larger than squirrels, and their noises are louder. Raccoons move much more slowly than squirrels and often make a rustling sound when moving around in your attic. They have over 200 vocalizations, including purring, hissing, growling, snarling, and whimpering. They can even screech like owls.

Squirrel Sounds vs. Bat Sounds

Squirrels are much easier to hear than bats, which are only active at night and make little noise as they fly in and out of your attic. Occasionally, you may hear squeaking sounds, especially if a colony of bats is living in your home. If you are outside after dark, you may hear bats flying to capture insects, including flapping their wings.

Other Squirrel Nuisance Concerns

Sounds and noises are just one concern of having squirrels living in your home. They chew through vents, pipes, ducts, wood, drywall, and siding. They build nests in chimneys, open pipes, insulation, and ductwork, causing your HVAC systems to malfunction and utility bills to rise.

Squirrels drag materials onto your roof, cluttering gutters. They also chew through siding and shingles, causing leaks and drainage problems.

Anyone with citrus or other fruit trees, gardens, or crops can expect damage from squirrels.

Squirrels harbor bacteria and diseases that they can transmit to humans, including the following:

    • Lyme disease

    • Salmonellosis

    • Parasites

    • Leptospirosis

    • Tularemia

    • Ringworm

    • Squirrel pox

How To Stop Squirrel Noises in Your House

The most crucial way to stop squirrel noises in your house is to eliminate all access points. Squirrels can squeeze through a hole as small as three inches. If they can fit their head through the hole, they can get the rest of their body through.

Sealing entry points is one of many exclusion methods to help stop squirrel noises in your house. Contacting a wildlife control professional is recommended. They have the knowledge, experience, and equipment to keep you and the squirrel safe.

CDC Warning

The CDC warns rodents like squirrels carry many diseases that can transmit to humans.
