At least for next year...you need to plant companion plants - in this 
case, plants to attract the good buys to deal w/ the bad bugs.

Any plant with umbelliferous flowers (that is, umbrella-shaped) will do 
- yarrow, fennel, queen anne's lace, parsley or carrots let go to seed, 
etc.  These attract parasitic insects, including the brachonid wasp, 
which parasitizes the tomato hornworm by laying it's larvae inside of them.

If you see white, rice-krispie looking "growths" on the hornworm, that's 
the larvae.  Don't kill the worm; leave it alone and the larvae will 
hatch, providing you with more wasps.
