The fall will soon be upon us, and I'm thinking about next summer and the onslaught of tomato hornworms. How do you go about preventing them? According to this site, those pesky things hang out all winter in your soil! (Much like those Japanese beetles).
So, I'm thinking that before I plant my fall crops (which I'm doing this week), that I'm going to ditch the current soil in my raised bed. That probably sounds like more work, but I'm not thrilled about having a brand-spanking new infestation next summer.
Any other ideas or management control options for those evil things?

Re: So about hornworms ...
you could not plant tomatoes next year and then the eggs won't have anythging to eat when they hatch.
I had stink bugs and the only organic solution I found was to not plant squash this year so the eggs from last year wouldn't have anything to eat... I didn't see any stink bugs this year.
When I was a kid we'd sew the hornworms.... the boys would stick them in the buckets with the tobacco leaves and when we were sewing the leaves we'd sew the hornworm too.
not plant tomatoes!????
hoping, what do you mean you sew with hornworms and leaves. I'm stumped.
OP, I went to that link because I wanted to see what hornworms were. It says that rototilling kills 90% of the larvae.
We do a pretty good job of tilling, so we usually dont have this problem. This is our first year with lots of aphids and hornworms (thank you wonderful heat) but they were not damaging to our plants. Reading most websites including the one you provided - tilling will prevent 90% from returning.
