I planted a few different peppers this past spring, but this little orange and black critter seemed only to have eyes (or fangs) for my tomatillo plant. I tried the soap and water method and I even picked some off and squished them myself, but the next day there was always one of their friends munching away at the leaves.
According to Anne Marie Van Nest, the insect looks like an adult three-lined potato beetle that migrated to my tomatillo to feed. “They probably didn't find their first love–potatoes–nearby and decided to try your tomatillos, she explains. They are in the same Solanaceae (potato/tomato/nightshade) family.
So how do I ultimately get rid of them?
Van Nest recommends looking for neat yellow/orange rows of eggs on the underside of the leaf and removing them to help control this pest. The even more voracious larvae cluster on the leaves munching everything in sight and are a disgusting soft-bodied eating machine.
The best way to control them is to remove the eggs, handpick the larvae and adult beetles and dump them into a bucket of soapy water. Spraying with soapy water is somewhat effective on the ones that actually get sprayed, but it doesn't work on those that arrive later.
