Squirrel Removal from Side Vent

Squirrels in Exhaust Vents: A Common but Serious Problem for Homeowners

Exhaust vents on the side of the house are one of the most common entry points for squirrels. These vents are often covered with thin plastic or lightweight materials that squirrels can easily chew through. Once the cover is damaged or removed, squirrels can quickly move in and build nests inside the vent, creating both a nuisance and a serious safety risk.

If you’ve noticed that your vent flaps are chewed, missing, or stuck open, there is a strong chance squirrels are entering your home through the exhaust vent. In many cases, homeowners can actually hear the squirrels coming and going through the vent, especially during the daytime when squirrels are most active. Scratching, rustling, or light thumping sounds near exterior walls are common indicators.

Once you’ve confirmed squirrels are nesting in the exhaust vent, the next step is knowing how to remove them safely and prevent them from coming back.

What Is the Best Way to Remove Squirrels From an Exhaust Vent?

The safest and most reliable solution is to contact a professional squirrel removal company. Experienced wildlife control professionals will first determine whether there are baby squirrels present, which is especially important during baby season (June to September). If babies are inside, improper removal can lead to trapped young, foul odours, and even deceased animals inside the vent.

Professionals typically use a one-way door system, allowing the squirrel to exit the vent naturally while preventing re-entry. Once the vent is clear, they install a wildlife-proof guard to permanently secure it. In the Toronto and GTA area, the average cost of squirrel removal usually ranges between $250 and $400, depending on the situation and accessibility.

DIY Squirrel Removal From an Exhaust Vent (If You Choose to Do It Yourself)

If you prefer to handle the issue yourself and save on costs, it’s critical to use the right materials. Squirrels can chew through plastic, wood, and even aluminum, so flimsy covers will not work. You will need:

• Heavy-gauge galvanized steel mesh

• Step ladder

• Flashlight

• Drill and drill bit

• Screws and washers

Using proper materials is essential for long-term prevention.

How Do I Get the Squirrel Out of the Vent?

The key to successful DIY squirrel removal is letting the squirrel do the work for you. Squirrels are active during the daytime and regularly leave the vent to forage for food. Wait patiently until you are sure the squirrel has exited before starting any work.

If the squirrel remains inside and does not leave on its own, you can create a stressful environment by making loud noises near the vent from inside the house. Knocking, tapping, or general noise is often enough to convince the squirrel to leave. Never attempt to grab or corner the animal, as squirrels can bite or scratch when threatened.

Cleaning and Securing the Exhaust Vent

Once the squirrel has left, use a step ladder and inspect the vent opening with a flashlight. If you see any nesting material inside, use a stick or similar tool to remove as much as possible. Nesting debris is a serious fire hazard, especially in dryer and bathroom exhaust vents, and should never be left behind.

After the vent is completely cleared, take your heavy-gauge steel mesh and form a small protective cage—typically around 7 inches by 7 inches by 3 inches, depending on the vent size. Hold the mesh cage over the vent, mark your drill holes, then drill into the exterior surface. Secure the mesh using screws and washers, ensuring it fits tightly with no gaps.

Once installed, this steel mesh guard will protect the exhaust vent from future squirrel and bird intrusions, while still allowing proper airflow.

Why Prevention Is So Important

Squirrels are persistent and will return to the same entry points if they are not properly secured. Simply replacing a plastic vent cover is not enough. Reinforcing exhaust vents with steel screening is one of the most effective long-term solutions for preventing wildlife entry.

If you’re dealing with squirrels in your exhaust vent and want a permanent, worry-free solution, professional squirrel removal services in Toronto and the GTA can ensure safe removal, proper vent protection, and lasting peace of mind.
