I ended up getting a bottle of
Ortho Max Flower Fruit and Vegetable Insect Killer, in which the active ingredient is
acetamiprid, but not before caterpillars all but destroyed my tomato plant.

It seems that I was mistaking caterpillar poop, for spider mites. I didn't realize it until the plant was pretty much infested with little green caterpillars and I had to prune the lower half of the plant again.
They aren't kidding when they say "Kills on contact". The morning after I applied this stuff to the plant I took a look and instead of a bunch of little green caterpillars, there were a few brown dead caterpillars. Destruction of the plant has stopped since I applied the stuff a week ago. The label says every 7 days so yesterday I went out with my sprayer to give the plant a good rinse down before re-applying.
I had thunder storms and rain all last week so the plant was kept in on the porch. I finally got to put it back out in the sun yesterday, and the plant's starting to bounce back with new growth.
I'm a little worried about using this stuff once the plant has bounced back completely though. This stuff kills just about anything, even
bees. The site says not to apply when there is bee activity around the plant. I might have to look into getting something less likely to kill the bees and reserve this stuff I have now for when things get out of control. Or figure out how to pollinate the tomato plant without bees.
I have a hunch that spraying the plant with alcohol, may actually attract certain types of insects. I'm wondering if the evaporating alcohol vapor could somehow mimic vapors released when a plants sugars naturally break down. One thing is for sure, my little green caterpillars don't mind being sprayed with alcohol at all.
