How to Get Rid of Squirrels in Your Attic
Finding squirrels in your attic can be frustrating. You may hear scratching above your bedroom, notice chewing sounds near the roof, or discover damaged insulation during a home inspection. These signs can indicate that squirrels have found a way into your home and are using the attic as a nesting area.
The best way to get rid of squirrels in your attic is to identify how they entered, check for baby squirrels, use an appropriate humane removal method, and seal all entry points once the animals have safely left. Simply blocking a hole or trying to scare the squirrels away can make the problem worse if animals remain inside.
This guide explains how to recognize a squirrel problem, remove squirrels humanely, prevent them from returning, and know when professional wildlife removal is the better option.
What Attracts Squirrels to Your Attic?
Squirrels usually enter attics because they offer shelter, protection from predators, and a suitable place to raise their young. Unlike an exposed tree branch or an outdoor nest, an attic provides a relatively enclosed environment.
Several conditions can make your home attractive to squirrels.
1. Gaps in the Roof and Soffits
Squirrels are skilled climbers and can reach roofs through trees, fences, drainpipes, and other structures. Once they reach the roofline, they may investigate weak spots around the eaves, soffits, fascia boards, and roof vents.
Small gaps can become larger when squirrels repeatedly gnaw at the surrounding material.
2. Damaged Roof Vents
Broken vent covers, loose screens, and deteriorating roofing components can create convenient access points. Squirrels may also take advantage of openings around utility lines or areas where repairs have deteriorated.
Inspecting these locations is important because repairing only the most obvious hole may leave another route open.
3. Overhanging Tree Branches
Branches close to your roof can provide squirrels with an easy route onto your property. Trees are a natural part of a squirrel’s habitat, but branches that touch or closely approach the roof can increase the chance of wildlife entering your attic.
4. A Quiet Place to Nest
Attics are often dark, warm, and rarely disturbed. These conditions can make them attractive nesting sites, particularly when a squirrel is raising young.
If you hear repeated scratching or chirping in the attic, avoid immediately sealing the opening. There may be a nest inside that requires careful attention.

Signs You Have Squirrels in Your Attic
Before deciding how to remove squirrels, look for signs that help you understand what is happening. No single sign proves that squirrels are responsible, but several clues together can help identify the problem.
Scratching and Scurrying Sounds
Squirrels are generally active during the day. You may hear quick footsteps, scratching, chewing, or movement above ceilings, particularly in the morning.
If the sounds are heavy or occur mainly at night, another animal may be responsible. Mice, rats, raccoons, and other wildlife can also enter roof spaces.
Chewed Wood or Roofing Materials
Look for gnaw marks around wooden fascia boards, soffits, roof vents, and other potential entry points. Fresh wood fragments near the exterior wall may suggest recent chewing activity.
Do not climb onto a roof to investigate unless you have the appropriate training and equipment. A ground-level inspection may reveal enough evidence to arrange a professional assessment.
Droppings and Nesting Material
Squirrels may bring leaves, twigs, grass, and other materials into an attic to build a nest. You might also notice droppings or disturbed insulation.
Avoid sweeping or vacuuming suspected wildlife droppings without appropriate precautions. If contamination is extensive, ask a qualified professional about safe cleanup.
Damage to Insulation
Squirrels may move or shred insulation while building nests. You might notice compressed insulation, loose material, or an area that appears disturbed.
Insulation damage does not automatically indicate squirrels, so look for other evidence before deciding on a removal approach.
Unusual Activity Near Roof Openings
Watch from a safe location to see whether squirrels repeatedly enter and leave a particular opening. This can help identify an active access point.
Do not block the opening while animals may still be inside. An animal trapped in the attic may become distressed and cause additional damage while trying to escape.
How to Get Rid of Squirrels in Your Attic
The correct removal method depends on the number of squirrels, the location of the nest, whether babies are present, and how the animals enter the building.
Use the following steps to approach the problem safely.
Step 1: Inspect the Attic and Exterior
Start by identifying signs of activity without disturbing the animals.
From the ground, look for:
- Gaps around roof vents and soffits.
- Damaged fascia boards and loose roofing components.
- Openings around pipes or utility penetrations.
- Tree branches close to the roof.
- Squirrels repeatedly entering or leaving the building.
If you can safely access the attic, look for nesting material, damaged insulation, droppings, and gnaw marks. Do not walk on unsupported ceiling surfaces or approach electrical wiring that may be damaged.
A thorough inspection should consider secondary openings as well as the main entrance. Squirrels can use more than one access point, so identifying only one hole may not solve the problem.
Step 2: Check for Baby Squirrels
This is one of the most important steps in humane squirrel removal.
Squirrels may raise young in attics during the spring and late summer. The presence of a nest, chirping sounds, or repeated activity near one area may indicate that babies are inside.
The Toronto Wildlife Centre’s guidance on squirrels living in attics explains why removing a mother without considering her young can leave dependent babies trapped inside.
If babies may be present:
- Do not seal the entrance.
- Do not install a one-way exclusion device without first assessing the nest.
- Avoid handling baby squirrels yourself.
- Seek advice from a qualified wildlife removal professional.
The goal is to remove the animals without separating dependent young from their mother or leaving wildlife trapped inside the structure.
Step 3: Allow Squirrels to Leave When Appropriate
In some situations, the safest approach is to give squirrels an opportunity to move out naturally. This may be suitable when there is no immediate danger, the nest can remain undisturbed temporarily, and the animals have a safe route outdoors.
However, waiting is not always practical. Squirrels may damage insulation, gnaw building materials, or access areas containing electrical wiring.
If you suspect damaged wiring, avoid disturbing the affected area and arrange an assessment by a qualified electrician.
Do not assume that a quiet attic means every squirrel has left. An animal may remain inside while others are outside searching for food.
Step 4: Consider Humane Exclusion
Humane exclusion aims to let squirrels leave the building without allowing them to re-enter through the same opening.
A one-way exclusion device may be suitable when the animals are confirmed to be using a particular entrance and no dependent young will be trapped inside. Its suitability must be assessed before installation.
The process generally involves:
- Identifying the active entry point.
- Checking for baby squirrels and other animals.
- Assessing alternative openings.
- Installing an appropriate exclusion device when conditions permit.
- Monitoring activity to confirm that the animals have left.
- Removing the device and permanently securing the entrance.
Exclusion is not a universal solution for every attic. Nesting conditions, building design, animal behaviour, and the time of year can affect the appropriate approach.
Step 5: Seal Entry Points After Removal
Once the attic is confirmed to be empty, repair the openings that allowed the squirrels to enter.
Depending on the location, repairs may involve:
- Replacing damaged soffits or fascia boards.
- Repairing loose roof vents.
- Securing suitable metal screening over openings.
- Repairing gaps around utility penetrations.
- Fixing damaged sections of the roofline.
Use durable materials appropriate for the specific building component. Squirrels can chew through some weak materials, so a superficial patch may not provide lasting protection.
Never seal an active entrance simply because you have not heard movement recently. Confirm that the animals have left and that no young remain inside before completing the repair.
What Should You Avoid When Removing Squirrels?
Some common DIY methods can injure wildlife, create additional damage, or leave the original problem unresolved.
Avoid Sealing Holes Too Early
Blocking an entrance before confirming that the attic is empty can trap squirrels inside. They may attempt to chew another way out, become distressed, or die in an inaccessible space.
Always confirm the animals’ status before carrying out permanent repairs.
Avoid Poison and Harmful Chemicals
Poison is not an appropriate DIY solution for squirrels living in an attic. It can cause suffering, create carcass-removal problems, and expose other animals to secondary risks.
Do not use mothballs, toxic chemicals, or other substances as improvised wildlife repellents. Products should only be used for their approved purposes and according to their labels.
Avoid Unsafe Climbing
Roof inspections can be dangerous, especially when surfaces are steep, wet, icy, or unstable.
Do not climb onto a roof without the necessary equipment and experience. A professional inspection is preferable when entry points are difficult to reach.
Avoid Handling Squirrels
Even small wild animals can bite or scratch when frightened. Gloves do not eliminate the risk of injury.
Keep children and pets away from wildlife, and do not attempt to pick up a squirrel or move a nest without appropriate guidance.
Avoid Assuming Every Noise Comes From Squirrels
Scratching in the ceiling can also indicate mice, rats, raccoons, or other animals. Using the wrong removal method can waste time and leave the actual issue unresolved.
If you cannot identify the animal confidently, arrange an inspection before taking action.
How to Prevent Squirrels From Returning to Your Attic
Removing the current squirrels is only part of the solution. Prevention focuses on making your property less accessible and reducing the conditions that attract wildlife.
1. Repair Roofline Damage
Check your roofline periodically for damaged soffits, loose fascia boards, broken vent covers, and gaps around exterior openings.
Address deteriorating materials promptly. If squirrels have repeatedly chewed a particular area, consider whether the replacement material needs additional reinforcement.
2. Install Suitable Vent Protection
Roof and attic vents should have appropriate, securely fitted screening that allows the ventilation system to function as intended.
Use durable materials designed for the opening. Do not block ventilation paths or cover vents in ways that could create moisture problems or interfere with the building’s operation.
3. Trim Overhanging Branches
Where practical, trim branches that provide direct access to the roof. Work near power lines or high branches should be left to qualified professionals.
Trimming branches may reduce easy access, but squirrels are capable climbers and can still reach buildings by other routes. It should be combined with structural repairs.
4. Manage Bird Feeders and Outdoor Food
Bird seed, fallen fruit, unsecured rubbish, and accessible food can attract squirrels to your property.
To reduce these attractants:
- Clean up spilled bird seed.
- Secure rubbish and compost containers.
- Collect fallen fruit where practical.
- Avoid leaving pet food outdoors.
- Consider feeder designs that reduce access by squirrels.
These measures will not guarantee that squirrels leave an attic, but they can make the surrounding property less attractive.
5. Schedule Periodic Exterior Checks
Check the roofline, vents, soffits, and other vulnerable areas after severe weather or when you notice new chewing marks.
Early detection makes it easier to address a small opening before it becomes a recurring wildlife problem.
For a broader overview of humane prevention strategies, see Ontario’s government guidance on preventing and managing conflicts with small animals.
Can You Get Rid of Squirrels in Your Attic Yourself?
Some preventive tasks are suitable for homeowners. Cleaning up spilled bird seed, trimming accessible vegetation, and arranging repairs to damaged exterior components can help reduce the risk of future entry. Removing squirrels from an occupied attic is more complicated.
DIY removal may be unsuitable when:
- Baby squirrels may be present.
- The entry point is high on the roof.
- Several openings are involved.
- The animals may be trapped inside a wall or ceiling.
- Electrical wiring or insulation appears damaged.
- You cannot confidently identify the animal.
- Previous attempts have failed.
Professional assistance can help establish what animal is present, identify its access points, and determine the most appropriate removal and exclusion method.
If you are comparing service options, Acme Pest Solutions’ guide to choosing a pest control company provides a useful starting point for evaluating a provider’s suitability.
Ask potential providers how they check for baby squirrels, confirm that the attic is empty, handle secondary entry points, and prevent future access. A clear explanation of the proposed work is more useful than a promise of a permanent result without an inspection.
What Happens During a Professional Squirrel Removal Inspection?
A professional inspection should focus on the animal, the building, and the conditions that allowed the animal to enter.
Identifying the Animal and Entry Point
The inspection may include examining the roofline, soffits, vents, and accessible attic areas. Gnaw marks, nesting material, tracks, and observed animal movement can help identify the likely access point.
If evidence is inconclusive, the inspection may need to consider other wildlife species.
Assessing Nesting Conditions
The technician should consider whether dependent young may be present and whether the proposed removal method could separate them from their mother.
This assessment is particularly important before installing exclusion devices or closing openings.
Selecting a Removal Method
The appropriate approach depends on the circumstances. Possible options include allowing the family to move naturally, using suitable exclusion equipment, or arranging specialist assistance when the nest cannot be addressed safely through ordinary exclusion.
No single method is appropriate for every property.
Checking for Damage
Squirrels may disturb insulation, chew building materials, or affect wiring. The extent of the damage determines whether repairs, insulation assessment, or an electrical inspection may also be necessary.
Wildlife removal and building repair are related but separate tasks. Removing the animal does not automatically restore damaged components.
Planning Prevention
After the animals have left, the remaining access points should be secured. Any secondary gaps that could permit re-entry should also be considered.

How Long Does It Take to Get Squirrels Out of an Attic?
There is no single timeline for every squirrel problem.
The time required depends on the number of animals, the location of the nest, whether babies are present, the accessibility of the entry point, and the work required to secure the building.
A straightforward exclusion may be completed more quickly than a case involving several access points or a nest containing dependent young. Follow-up monitoring and repairs may also be necessary.
Be cautious of anyone who guarantees a specific completion time before assessing the property. A responsible plan should account for the animals’ welfare and the condition of the building.
Frequently Asked Questions (Faqs)
The fastest appropriate method depends on the situation. A professional inspection can identify the active entry point, check for babies, and determine whether humane exclusion is suitable. Sealing an entrance without confirming that the attic is empty can create a more serious problem.
Some squirrels may move their nest when conditions change, but you should not assume that they will leave promptly. If there is no immediate danger, a carefully assessed period of natural departure may be an option. Persistent activity or building damage may require professional intervention.
A one-way door can allow squirrels to exit while preventing them from returning through that entrance. However, it should only be used after checking for dependent young and assessing the entry points. Improper installation can trap babies inside.
Squirrels generally avoid people, but they can bite or scratch if cornered. They may also damage insulation, chew building materials, and potentially damage electrical wiring. Avoid direct contact and arrange appropriate inspections if you suspect structural or electrical damage.
A lack of noise is not enough to confirm that the attic is empty. A proper assessment considers observed movement, the condition of the entry points, and signs of continued activity. A qualified professional can advise on suitable monitoring and verification methods.
Repair damaged soffits and vents, secure appropriate screening, address gaps around the roofline, and reduce access to outdoor food. Trim branches that provide easy roof access where practical. Prevention works best when all relevant entry points are addressed.
Do not attempt to remove or relocate baby squirrels yourself. Young animals may depend on their mother, and separating them can cause unnecessary harm. Seek guidance from a qualified wildlife removal professional or an appropriate wildlife organization.
Yes. Squirrels may disturb insulation when building nests or moving around the attic. They can also leave droppings and nesting material behind. After removal, assess the affected area to determine whether cleaning, repairs, or insulation replacement is necessary.
Conclusion: Keep Squirrels Out With Humane Removal and Prevention
Getting rid of squirrels in your attic requires more than blocking a hole. You need to identify the animal, assess whether babies are present, choose an appropriate humane removal method, confirm that the attic is empty, and repair the openings that allowed the squirrels to enter.
Avoid poison, unsafe climbing, and premature sealing. These shortcuts can put people and wildlife at risk while leaving the underlying problem unresolved.
