Loopers on my plants what Bt works well?

I'm considering doing a two part setup... Hitting them once with pyrethrum to kill the ones already on the plant then spraying down with Bt right after to kill them off when more hit the plant. These guys are incredibly proficient in runing a plant, ate the entire selection of buds on my biggest plant in a day.

Just wondering what Bt packs a serious ass punch.
