Otherwise, would need to go out several times a day and manually pick the
worms off. The problem is the tomato worms are very difficult to see. If you
don't keep the insects off, they'll eat all the leaves from the plant and you won't
have tomato or very small poor tomatoes. AND those tomato worms are horrible
looking creatures. I put vinegar and dish soap in bottle, and if I see worm I spray
it and worm fall off and then I kill worm.
