I can see you are trying to be a good neighbor - Jstpssng. However - there are those times when the ambitions of a beaver family are simply incompatible. It may be best to get the Game Dept to live trap and move them.
Around here - if they are causing damage - the Game Dept is Jonny-on-the-spot to move them to a better location.
I just paid to have him moved 3 weeks ago... and was guaranteed that he didn't come back. There are so many swimming around here that just like woodchucks, if there's an empty home it's going to get filled. Actually the person who told me the beaver had come back was mistaken. I was there today and the house is empty.If you relocate trapped animals it can take them up to a week to find their way back.
