If you call pest control in Massachusetts and they get an animal from your property they have to kill it due to the risk of disease among other factors. I got my fur trapping permit this year because I got tired of paying people to come grab various animals from ripping out the insulation in my office and chuck them in a back lot somewhere. At least now I'm able to harvest the fur and parts of value during the trapping season...and yes you can eat all of the fur bearers in Massachusetts with beaver on top of that list.
