Rotenone is a good control for those. There seems to be some debate over whether it is "organic" or not. I use it when necessary. If you kill off the infestation of larvae with one application, hand picking the adults will probably be sufficient after that.

Potato beetles show a distinct preference for certain crops over others. Their very first choice, in my experience, is eggplant, which they can demolish while leaving peppers and tomatoes relatively untouched.

I had them on my tomatillos too. They like my husk Cherry when i grow them. I just squashed them all with my fingers and scraped off the yellow egg clusters and the problem seems to be solved.

I have a pepper plants and eggplants with leaves actually touching the infested tomatillos. So far none of the larvae or damage have been seen on any peppers or eggplants.

I've been hand picking, but its hard to get em all (I have 8 tomatillos all heavily infested) Did I say they are disgusting looking too?

The tomatillos I really don't care about anymore (they are so devastated it will take a while for a come back) I just don't want the same fate for my peppers.

Thanks for the tips on hand and chem control.

I had those little buggers on my tomatillos earlier in the year. I squished them and eventually the plants recovered. Fortunately, they never spread to any other plants, they just seem to love tomatillos.

Yeah, the definitely like tomatillos. My concern was that if I remove the Tomatillos is if they will settled for 2nd best.
I removed nearly a full jar of larvae plus ~30 leaves with the orange eggs. I only found 3 adults. I'll leave the tomatillos in, although a few a struggling to recover in the heat.
