[quote="MamaIve12" I know that gazillions of critters are going to emerge from these pellets and kill it. . [/quote]
Wait, I think you misunderstood. The pellets will not produce any new critters, I don't think. They are waste material, not eggs.
I think you're going to have to try scouting your bougie after dark, maybe. Use a flashlight to see if you can find the caterpillars. Wear your gloves, pick them off and stomp them. That's the most environmentally sound method, if there aren't too many. Otherwise, you might try some Bt sprayed on the leaves. It's not harmful to other insects, just targets whatever eats the leaves.
