What can I use to control them that is not harmful to humans eating
the cabbage?

Bacillus Thuringiensis.
The only place i could find it locally was Post Nursery off of
401 a bit north of burlington mills rd.
The place for pot growers off of hillsboro street (5th season
or something like that) might have it.
Some Ace Hardwares might have it.

Also either permethrins or pyrethrins (Whichever one is in Rotenone).
I've seen Rotenone in Ace and Walmart.

The other thing to try is bifenthrin (Ortho Max for granules, I forget the
name for the liquid for spraying). Follow the california guidelines for
use on food crops if you're paranoid about residue. It's a synthetic
version of the previous item complete with a fairly high half life.
