Preventing conflicts with beavers
What to do if beavers are causing damage to your property.
How to make your property uninviting
- plant trees and vegetation that beavers don’t like, such as elderberry, ninebark and twinberry
- wrap individual trees in metre-high, galvanized welded wire fencing, hardware cloth or multiple layers of chicken wire
- paint tree trunks with a sand and paint mix (120 millilitres of masonry-grade sand per litre of latex paint) to protect trees from beaver damage
- protect large areas by installing 1.5-metre high field fencing and keep the bottom of the fence flush to the ground to prevent beavers from entering underneath
- protect areas along river and stream banks with electric fencing
How to remove beaver dams
Destroying a dam should only be considered after other techniques have been tried.
If dam removal is necessary:
- exercise extreme caution to prevent downstream flooding, damage to natural habitats and property damage
- check with Fisheries and Oceans Canada to avoid causing serious harm to fish and fish habitat by following best practices
- you may be held liable for any property damage that occurs downstream
How to prevent flooding
Contact your ministry office for advice on a variety of techniques to control the level of water behind a dam.
Lethal action
- as a last resort, a farmer may humanely kill or trap beavers that are damaging or about to damage their farm property
- if you are using a firearm, you must follow certain regulations and local bylaws
- a landowner may hire an agent, including a trapper, to act on their behalf.
