I recently saw a couple Youtube videos on how to find any tomato worms on your plants. Get a black light flashlight and go out at night and shine it on your plants. No matter how small they are, the tomato worms will glow and you can easily pick them off......
Great advice. There are a few here who swear by that and have had great success ‘Tomato Hornworm Hunting.’
