Beavers

Beavers

​​​​​​​​​​​​​​​​​​Beavers are the largest rodent in North America and usually live in small lakes, rivers or wetlands. Beavers build dams from woody material, which helps create new wetlands, reduces erosion, and regulates the flow of rivers and streams. Beavers are not dangerous unless they feel trapped or cornered, and that is when they will choose to stand their ground.

Beavers In Brampton pamphlet​ provides additional information, including what the City is doing, while it complies with provincial regulations and keeps infrastructure and property from damage.

Before action is taken to address any beaver activity, our Wildlife Response team will assess the site to confirm:

  • The level of risk to surrounding residents, property and infrastructure
  • Potential solutions and the level of effort required to mitigate risks
  • The impact the suggested solution may have on beavers and future activities

Brampton Animal Services will first explore installing a pond leveller (also known as a beaver ​​baffler)—a pipe-and-fence system installed through the dam that allows water to flow through at a controlled level, preventing flooding while leaving the dam and the beavers in place. Removal of the beaver is considered only when a baffler is not feasible for the site, recognizing that beavers play an important role in local wetland ecosystems and that removing them often results in new beavers moving into the same habitat.

If beaver activity impacts your personal property, consider the following recommendations:​

​
  • By wrapping trees using heavy galvanized steel mesh or hardware cloth, you can discourage beavers from cutting down trees on your property.
  • When wrapping trees, make sure to:
    • Avoid using chicken wire if possible
    • ensure the wrap doesn’t impede the tree’s natural growth
  • Painting tree creates a gritty texture to the tree that beavers dislike and acts as a textural repellent. A mixture typically requires:
    • 5oz of fine masonry-grade sand per 1 litre of exterior latex paint
    • Applied 3-4 feet up the trunk​​
​ Note: Do not use on young trees with a diameter of less than 2 inches, as it can restrict growth.​

​Beavers are not great climbers, and a fence can cause the deterrence needed to keep them f​rom entering your property.

  • Beavers are very particular about the trees they like and choose. If you are to plant the following trees, you will not attract beavers to your property
    • Elderberry
    • Ninebark
    • Twinberry
    • Evergreens
  • ​You can also look at spraying your trees with a bitter-tasting repellent; this might wash off with the rain, so be prepared to maintain this solution.​​​ ​
