Chipmunks dig / burrow right under netting / fencing.
And sometimes they are too STUPID to get back OUT of the mesh net.
Very short memory - except when it comes to where the tomatoes are.
Happened to me once - a totally panicked chipmunk bouncing around
the inside of the mesh trying to find it's way back OUT.
What an annoyance.
They are NOT the most intelligent of creatures - nope.
Hmmmm...I'm pondering...

I’m sure you’ve tried everything. Go to your local farm market....support your local farmers. :-)
If you give them plenty of sunflower seeds they will leave your garden alone
I’m having the same problem, only tomatoes up to about 1’ up, half eaten. At first I thought it was my hen, but now I’m thinking chipmunk or raccoon - not sure how to tell the difference?
