The Hidden Dangers of Squirrels: Risks and Prevention for Alberta Homeowners

Squirrels are a common sight in many neighborhoods in Alberta, Canada. While they may appear harmless and even cute, they can pose serious risks to homeowners. In this blog post, we will explore the potential dangers squirrels can cause and what steps you can take to prevent them.

1. Structural Damage

Squirrels are excellent climbers and can easily scale trees and buildings. Once on your roof, they can chew through shingles, fascia boards, and vents, creating entry points for water and other pests. They may also gnaw on electrical wiring, which can lead to a fire hazard. The damage caused by squirrels can be expensive to repair and can compromise the integrity of your home.

2. Health Risks

Squirrels carry diseases that can be transmitted to humans. They may also carry fleas, ticks, and mites, which can cause allergic reactions and transmit diseases like Lyme disease and Rocky Mountain spotted fever. Additionally, their droppings can contain harmful bacteria and fungi that can cause respiratory problems.

3. Garden and Landscaping Damage

Squirrels are known for their love of nuts and seeds, which means they can cause significant damage to your garden and landscaping. They may dig up newly planted bulbs, eat vegetables and fruits, and strip bark from trees. Their digging habits can also create holes in your lawn and damage irrigation systems.

4. Noise and Disturbance

Squirrels are active during the day and can make a lot of noise as they scurry across your roof or through your attic. Their constant scratching and gnawing can be disruptive and may cause sleep disturbances.

Prevention and Control

To prevent squirrels from causing damage to your home and property, there are several steps you can take:

  1. Trim back tree branches that overhang your roof and gutters to prevent squirrels from accessing your home.
  2. Install metal mesh screens over vents and other entry points to prevent squirrels from gaining access.
  3. Seal any gaps or cracks in your home’s foundation and exterior walls to prevent squirrels from entering.
  4. Remove any potential food sources, such as bird feeders or open garbage cans.
  5. Use squirrel-proof bird feeders and store birdseed in airtight containers.
  6. If you have a squirrel infestation, contact a professional pest control company to safely remove them.


Squirrels may seem like harmless creatures, but they can cause serious damage to your home and pose health risks to you and your family. By taking preventative measures and addressing any infestations promptly, you can protect your home and enjoy a pest-free living environment.
