Just so nobody is concerned I have a license to kill beaver anytime from the commonwealth. These two f***ers started rebuilding a dam on my land within minutes of a friend destroying the dam with is backhoe. I have shot two more since then, night vision, suppressed 5.56 rounds straight to the beav.
At least you can shoot the damned things. In MA they're a fur bearing animal or some bullshit and you can only trap them, IIRC.
