    Squirrel Removal

    How does St. Catharines Pest Control and Wildlife Services remove squirrels from homes and businesses?

    We use a one way door combined with appropriate exclusion techniques to remove the squirrels from your home and to ensure that they cannot regain entry, ever. We will send a technician out to your home to do a thorough inspection of all possible entry points. Our trained technician will also inspect your roof for other possible areas that are vulnerable to squirrel entry. We will attach a one way door which allows the squirrel to leave. The door cannot be opened from the outside. All squirrels whether there is one or more will be able to leave through the door. The technician will also recommend securing the other areas that the squirrels could use as an entry into your attic. We use steel wire mesh to secure these areas that are rust proof and last for many years.

    ****Squirrel baby season starts early March through to July. During baby season a technician will have to inspect your attic for any babies. If the technician finds babies they will be placed in an incubator box on the roof where the mother can easily find them once she leaves through the door and she will take them away.

    By ensuring the mother has easy access to her offspring, we can reduce her desire to re-enter your attic in addition to preventing her from causing damage to your roof. This process is completely humane and not only removes the animals from your attic, but also permanently prevents them from coming back in the future.


    Why not live-trap?

    Simply put, live trapping is inefficient. And it does not prevent one of the other hundred squirrels in your neighbourhood from reentering. Even if you trap the right squirrel, it is illegal to move it more than 1 kilometer from where it was trapped, and it may find its way back. Once an animal has lived in your attic the den site will omit an odour that attracts other squirrels and wildlife. Unfortunately deodorizing foggers don't work and squirrels will always small the den site. Also live trapping can be very costly as once the trap is set up, anytime it is tripped or needs to be rebaited it will require a paid visit. The trap may catch another squirrel and not the one that is living in your attic. It may catch some other unintended animal or the bait may be consumed by mice. The bait may deteriorate if the trap is outside and have to be rebaited. Trapping takes time and may never work. Therefore, it is important to fully exclude, rather than trap the animal, and then seal off the area in order to prevent other animals from taking up residence. Exclusion is the most cost effective and efficient way to get rid of your squirrel problem permanently. The squirrel is usually permanently removed within hours. Once the exclusion is complete we will provide you with a warranty on the services rendered.


    One way to prevent squirrels from gaining access to your home is to regularly clean your eaves troughs. By cleaning out your eaves troughs at least once per year you can prevent your fascia from rotting. Squirrels can easily gnaw through rotting fascia, so it is important to keep the exterior of your home in good standing. Be sure to also check your roof for wear and tear by looking for missing or damaged shingles. Bird feeders tend to lure squirrels and other pests to your home. If you donít want squirrels or other wildlife skulking around your home it is best to remove the bird feeder. These suggestions cannot guarantee that squirrels will not come onto your property; however, this should help.

    How can squirrels enter my home?

    Squirrels gain access to your home by gnawing their way in. One of the most common access points for a squirrel to enter your home is an attic vent. A squirrel can gnaw through this vent and enter your attic quite easily.

    Plumbing mats are another means by which the squirrel may enter your home. At the base of the plumbing stack is a seal that prevents water from leaking into the attic space. Squirrels will gnaw at the seal, which in turn will create a hole in the roof that they can enter through.

    Squirrels are excellent climbers, and can easily access the most remote parts of your home or business. Squirrels have even been known to go into chimneys and establish a den site on top of the damper. Installing a wildlife cap is the best solution to prevent this from happening. Once the squirrel has taken up residency in your attic you will immediately begin to notice. Squirrels are early risers (they tend to wake up at around 6:30 a.m.) and enjoy running around, which can be extremely noisy and bothersome. The noise can often be heard from two floors below. Other animals are also attracted to the scent of a den site making it a target for more unwanted wildlife such as raccoons or even bats.

    What kind of damage can a squirrel cause to my home?

    Squirrels may gnaw holes in the roof where water may leak and cause extensive damage. Squirrels are a common cause of power failures and fires in houses. The wiring in attics looks like roots and sticks to the squirrel, which in turn makes it gnaw on the wires in order to add to a nest site. Squirrel feces also contain certain bacteria that can be harmful to humans, so it is best to deal with the problem immediately

    Attic restoration

    Over the course of several months, a squirrel can cause extensive damage to your home or business, especially if there are babies involved. Long-term damage can and will occur if the animal is not removed from your home immediately. Squirrels tend to trample insulation . Once the insulation is crushed, there is nothing that can be done except to replace it. You'll notice an increase in your heating bill, by as much as 100 per cent. This is why it is important to deal with the problem immediately. Reinsulating your home may become necessary, and this can be quite costly.

    Our technicians may recommend an attic restoration inspection in order to determine the extent of the damage and to offer advice on what you should do next. Attic restoration involves sterilizing the attic, removing all of the damaged insulation and repairing the vapour barrier. The technician will also do a thorough inspection of the wiring, to ensure it has not been chewed or damaged. St. Catharines Pest Control and Wildlife Services offer this service in addition to exclusion and can only be quoted once the animal has vacated the attic.

    What do I do if I have a squirrel problem?

    If you suspect you have a squirrel problem on your property please do not hesitate to call St. Catharines Pest Control and Wildlife Services at 1-888-390-PEST (7378).

    One of our licensed and friendly wildlife removal technicians will be happy to inspect your property and give you a free quote. If you think you have a squirrel problem it is better to deal with the issue sooner rather than later as ignoring the problem could lead to future complications.


    There are 2 species of squirrels that commonly enter our homes and buildings. They are the American Red Squirrel and the Eastern Grey Squirrel. Chipmunks very rarely get in your house as they are ground squirrels and donít get up to the more vulnerable areas on your roof.


    The Eastern Grey Squirrels natural range is in eastern Canada and the U.S. They have now become an invasive species in many parts of the world. The Eastern Grey is a highly adaptive species able to successfully compete with almost all other squirrel species.


    As its name suggests it is usually Grey however they are also commonly black and occasionally even brown or reddish. The head and body are 23 - 30 cm (9 - 12 inches) and the tail adds another 19 - 25cm (7.5 - 10 inches). Grey squirrels weigh between 400-600g (14 - 21 ounces).


    Grey squirrels bury thousands of nuts over hundreds of locations throughout the summer months. They have excellent memories and are able to retrieve the nuts very accurately even months later. This is the single biggest advantage that Greys have over other squirrel species. Greys tend to be active early in the morning and late afternoon avoiding lots of activity during the hottest hours of the day. During the summer they build large leaf nests to live in. They will rebuild these leaf nests regularly to avoid fleas and other parasites that accumulate quickly during the summer. Grey squirrels do not hibernate. They forage for nuts most days during the winter.

    Life Cycle

    Eastern Grey squirrels in more southern areas may breed twice during the summer. In southern Ontario most years females only breed once a year. Litters are usually born between March and April and are made up of between 1 and 7 kits. In the wild Grey squirrels may live about 8 years.


    Grey squirrels prefer deciduous forests to coniferous but can eat cones if needed. They eat nuts, bark, berries, seeds and occasionally birds or eggs. In urban areas populations proliferate due to a lack of predation and ample food sources.


    American Red Squirrels are much more territorial than Grey squirrels and not as densely populated. Reds prefer to eat the cones of coniferous trees but will also eat hardwood nuts, seeds, fungi, flowers, bird eggs and mice. They tend to cache their nuts in only a few places with large numbers in each location. They also tend to store a lot of nuts in or close to their den site.


    Red squirrels weigh about 225g making them about half the size of a Grey squirrel. They are reddish and have a distinctly white underbelly.


    The red squirrels small size makes it much easier for them to find cracks large enough for them to squeeze into to get into your attic. They are fiercely territorial and will fight the larger Grey squirrels that live close by. They are excellent climbers and can access almost any point on buildings and homes. Unlike Grey squirrels, they are small enough that they will often get down into walls and between floors in a building.

    Life Cycle

    In the wild, Red Squirrels have a life expectancy of 4 or 5 years. They have 1 or 2 litters per year of about 3-5 kits. Red squirrels are sexually mature in their first year and usually breed during their first spring.


    Red squirrels tend to store a large number of nuts and cones in your attic which means they will try harder than a Grey squirrel to get back in. It is doubly important to be thorough in performing the exclusion work on your house. Red Squirrels are diurnal (active during the day) with peak activity being about 7:30am. Usually they are out every day but during a heavy snow storm they may stay in for a few days.
