Additional Beaver Control Control Information

Damage Prevention and Control Methods

Exclusion

Fence small critical areas such as culverts, drains, or other structures. Install barriers around important trees in urban settings.

Cultural Methods and Habitat Modification

Eliminate foods, trees, and woody vegetation where feasible. Continually destroy dams and materials used to build dams. Install a Clemson beaver pond leveler, three-log drain, or other structural device to maintain a lower pond level and avoid further pond expansion.

Frightening

Shooting of individuals or dynamiting or other continued destruction of lodges, bank dens, and dams, where legal, will occasionally move young colonies out of an area.

Repellents

None are registered; however, there is some evidence that repellents may be useful.

Toxicants

None are registered.

Fumigants

None are registered.

Trapping

No. 330 Conibear® traps. Leghold traps No. 3 or larger (including coil-spring types with equivalent jaw spread and impact). Basket/suitcase type traps are primarily used for live trapping. Snares can be useful, particularly in dive sets and slides where legal. Steel leghold traps.

Shooting

Rarely effective (where legal) for complete control efforts and can be dangerous to humans.

Other Methods

Other methods rarely solve a beaver damage problem and may increase risks to humans and nontarget species.Generally not practical.
