Trouble is some of those larger bugs also like basil and veges too!
That eat inside out bug sounds almost like a sci-fi horror movie. You've given a screen writer an idea for a Movie3!
If I was you with a few plants cookworm and wanting to protect, I would consider a larger tub..you know..one of those rectangular ones that you can get fairly cheaply in polystyrene..and put then in that and then develop a wire 'cage' to put around it. That way you have one element only to life off if you want to access your plants.
You can also..if you want a creative, nutty look..use old birdcages for this sort of thing too although obviously they are not going to take plants climbing up high..
I think your chipmunk would have come down eventually anyway tho mainly at dusk or early morning if it wasn't used to you.
I tell you..I HATE going to outdoor places where while you're eating you get harassed by pushy pigeons..flying rats!
