I personally relocate beaver with Conibears and yes, quite often juvenile beavers will return at some point. Sometimes I will go years without seeing them and other times it is only months. I will upload you a image off a beaver tunnel. I currently have a pond with the water pulled down for repairs because tunnels dug by beaver into a dam and emergency run around.
Oh I didn't need to see that......didn't know they dug.
Just found where beavers cut two trees on my pond so I wrapped three trees in the yard with net wire to prevent them from getting chewed on.
I need to find and give them a craniotomy ASAP.
