kwselke, I just thought I'd mention that I do preventative treatments for caterpillars in general and rarely see any hornworms, cornworms, leaf rollers, inch worms, etc. later on in the season. When the live oaks start to "bloom" and start dropping leaves, I throughly spray my tomato plants and also all my emerging cannas with Bt.
Then I repeat a couple of weeks later. That's it. This seems to prevent the population from getting a foothold.
