If the roots are good and the sun doesn't cook them they usually come back.
I have a mite problem and my plants are sticks at one time or another but they usually come back.
Get some catterpillar killer for your plants.
Shop around,I see it for $6.00-$10.00 at different places.

Yeah, long as the roots are still good (tomato worms don't bother roots), you should still be fine.

Move them into the shade, give them some water, and they should bounce back. Peppers are pretty resilient once they get going.

i got them in the shade on the porch now. should i fertilize them with some phosphorus to help give them a kick start.
