I think I got a few hornworms trying to eat my pepper plants.
I have been using the dish soap, veggies oul, baking soda and water mix to best them back.....been effective.
I spray every 2 or 3 days (unless it rains.)
I learned the hard way to not try and spray until the sprayer jug is nearly empty.
My pick up tube grabbed some of the mix that settled to the bottom then the next day the 3 plants who got a foamy spray looked like they had been burned to a crisp on the BBQ....black and shriveled up crispy leaves.
Black light flashlights are GREAT for finding tomato hornworms in late evening/night. Their white patches glow under black light and it’s far easier to find them then.
Scorpions also glow un der black light. I got my black light flashlight at Wal-Mart.
