Are woodchucks harmful?

[Chris]

They eat a ton, they will mow down a garden. But if you're okay with that, or think you have it under control (I've had them get inside of fencing) then no, they aren't harmful, just big fat bunny rabbits.

I agree with Chris, as long as you have things under control just let them be. But you may also want to do a bit more research about their habits in case they reach a point where you can no longer control them. Good luck!
