Advice on Trapping Beavers. Services Available in Massachusetts
Beaver trapping was the traditional method to resolve beaver conflicts. Unfortunately though it is usually a short term solution to beaver problems because new beavers can relocate to the trapped area. It is most useful when flow devices are not feasible. In our experience trapping is necessary for approximately 25% of beaver-human conflicts. Most issues are better managed with flow devices.
If trapping is used in a region with a healthy beaver population, it typically needs to be repeated every year or two because new beavers will be attracted and relocate to the habitat. Therefore wherever feasible we recommend flow devices (pond leveler pipes or culvert protective fences) because they are the most long-term and cost-effective solutions to beaver related flooding,
In Massachusetts, a regulated beaver trapping season starts November 1st and ends April 15th. In MA and many other states trapped beavers cannot be relocated, they must be killed.
Outside of MA trapping season if there is a threat to human health, safety, or property, the local Board of Health can issue a permit to trap beaver. This permit is necessary to use a lethal Conibear trap at any time of the year in MA.
If you are interested in becoming a licensed trapper contact your State Wildlife Agency for additional information. In MA visit the Massachusetts Division of Fisheries and Wildlife website.
