These caterpillars are so big (three inches long or more) that it would seem to be easy to control them just by picking them off. And so it is, sometimes. The problem is that their pale green color provides excellent camouflage, and the nymph and larval stages are far smaller and less obvious. If there are only a few, picking them off works well. If there are more than a few, other measures may be called for. One of these is Bt, Bacillus thuringiensis, an organic treatment that can control numerous other problems as well.

Oh how I hate these. Look at this huge bugger I found gobbling down one of my baby tomatoes. I put it on the garden clippers for size context. I suppose sacrifices of some must be made for the good of the whole but my goodness he's a fatty. I hope there aren't little hornworms running around that I haven't caught yet. These buggers are the ones that put the little and sometimes BIG holes in your tomatoes. If you listen closely in the quiet of the night you can actually hear them crunching. Then take your flashlight and go a picking....
