Good Morning Matt, 

Thank you for contacting the U of M Extension Service. 

Do you have deer in your neighborhood? Is the fence tall enough that they cannot reach over the fence to munch on your garden?   From viewing your photos, I believe it is rabbits. Are you sure they are unable to access your garden? Have you buried your fencing in the ground so they cannot dig a hole through the ground? This could possibly be squirrels.

I am wondering if you have chipmunks? They could probably get through your fence. But the damage from your beans it taller than a chipmunk. 

It really looks like some kind of critter damage. There are some non-toxic repellents. 

Good Luck!
