I'm a new gardener, growing about a dozen herbs in containers on my porch. I had a beautiful baby bok choy plant get completely eaten by little green caterpillar looking bugs two weeks ago. They ate all the leaves off within a week. I thought I'd gotten rid of them but they now seem to have made their way to my cilantro plant.

Not sure how they've gotten onto my porch but they blend into the herbs pretty well. Does anyone have any ideas for keeping them away? I might try some sort of mesh cage on the bok choy when I start over in a large planter, but the other herbs are all in their own pots. These herbs are for my enjoyment, not the bugs'

Go to a good nursery or farm supply and get a bag of diatomaceous earth. Sprinkle it all around on the soil when dry, and it will kill any caterpillars or other bugs that step in it. The microscopic dried sea creatures are very sharp and cut them, while safe for pets and humans. The only problem is you have to do it again when wet. I use a drip system so only a small area gets wet when it comes on. It solved my flea beetle problem.
You could also go out at night with a flashlight, pick them off and squish.

I use a mixture of Murphy's oil soap with some water and rubbing alcohol in a spray bottle, about a quart bottle with 3-4 tablespoons oil soap and the rest half/half water & alcohol. I use it for aphids, but I think it should work on soft bodied insects. It shouldn't harm the plants and is good for vegetables or herbs that you are going to eat.

Thank you Hemlock and Bobilee for the advice. I'll give these suggestions a try.
