—Since they aren’t on or in dirt, the killers in the ground won’t get them.—
I wouldn’t bet the family jewels on that. My containers are 30” from the ground and I picked a nasty 3” cattypillar from a pepper yesterday that had decided to munch on banana pepper leaves.
I picked suckers from my two maters and a few peppers in my Raised Container Garden. My wife’s Ground Level Garden has maters about 30” with multiple blooms. She did get the stakes up. Oh how nice an 18V cordless drill with a 24” long, 3”dia garden auger does for installing 8’ mater stakes.

The difference in our situation may be your containers even though up from the ground, are on open land where caterpillars would be and could crawl up there. Remember, I am in town and there are high brick walls around my garden so no open ground for critters to crawl inside. I have never seen a caterpillar here. If that changes, you can be sure I’ll tell you. :o)
