Beaver Trapping with Snares

Managing beaver populations is typically done through regulated fall and/or winter trapping seasons. Landowners need only to give permission to licensed fur trappers to remove beaver during the legal trapping season. If beavers are causing severe damage, state wildlife agencies may issue special trapping permits to professional wildlife control operators . In some states, fur trappers can assist during closed seasons under certain condition. Trapping beaver requires training and proper equipment to be done effectively and ethically. There are strict regulations regarding types of legal beaver traps and their placement (generally underwater ). An inexperienced person attempting to trap beaver can wise them up quickly, making them very difficult to trap. This often results in more expense and time when an experienced trapper is finally brought in to complete the job.

While we attempt to provide guidance about state and federal regulations pertaining to specific species and control techniques, we do not provide information about local jurisdictions (city, town, county, etc.) where regulations may be more restrictive, especially as it applies to discharge of firearms, transport of animals or use of trapping equipment. Contact your local city or county government to inquire further. No guarantee is made that information (or lack of information) associated with a species or control technique is completely accurate or current. You should become familiar with federal, state and local laws before beginning any wildlife control activities.
