The first thing that I noticed after the muskrats moved in were shredded cattails and almost overnight - muddy water. Then the APW started to disappear.
Then they started on the arrowhead. It didn't take long at all for them to wreck the place. The pond looked like a war zone two weeks after they showed up.

We shot five of them. I don't know how many are left because they don't show themselves. Conibear traps are here and going in this weekend.
