And then there's the issue of "what will those worms turn into" ? (for me, at least)
One year I had a horrible infestation of some really ugly caterpillars, eating petunia plants, totally devouring a couple of borage plants, and moving on to anything and everything else... only after I sprayed them all with Bt did I learn they were Painted Lady butterfly cats
. Actually, they were doing so much damage I'm not sure I would have done anything differently -- but at least I would have been making an informed decision about killing them.
The tomato hornworms turn into sphinx moths, aka hummingbird moths... which I love seeing visit my flower boxes on the deck. Ahhh -- everything is such a trade-off!
