i too, have c**tapillars, i even use treatment ;p . i was just taking of yellowing leaves the other day when i got home from a vacation and saw some mold, which on a closer look i realized was caterpillar poop and damage...upon even CLOSER inspection i had even more, all around the parts of my makeshift greenhouse that had an opening in the flap. quite the major bummer to say the least, had to take off a nice chunk of buds, but not enough to make me completely break down on the spot. i still have a good amount coming off the plant, and if you take care of it soon enough you will too.
my opinion? if you cant pick 'em, spray with bt-unless someone proves otherwise. or a light pyrethrum spray, its organic and breaks down fairly quick, though you may not like to spray, you can always still do a pre wash a bit before you flush, just to take care of them for the moment...if you have 2 weeks, you have time.
