To the person who said she had a problem with the caterpillars getting into the cabbages/brassicas: here's what I have used on the broccoli that seems to help. Get a few hot peppers, chop them up and put them in a spray bottle (seeds and all). Fill it with hot water, shake it up and let it sit a while. Then you can spray it on the plants (just whatever you do, don't spray upwind) and it seems to repel the bugs. You'll have to reapply it every few days and after rain; keep the bottle in the fridge.
