Wisconsin also requires written authorization to use explosives to remove a vacated lodge. Check the laws of your state for information on using explosives to remove a beaver dam. Both the Wisconsin and Nebraska articles discuss trapping options and where to find further information. Shooting is an option in areas that allow it, but it may not be effective due to restrictions. If you trap or shoot, you must comply with all shooting, hunting, and trapping laws.
Various organizations offer nonlethal beaver control.
Consult with local wildlife authorities for information.
