AAWWW just smoke it. You know frass is considered a delicacy in Papa New Dehli?
J/K. Man, sorry I should of put a question mark at the end of my post up there and not a period. Didn't mean to sound factual as I have little expierence with bug poop problems. One time I did have dirty buds like the pics I seen of your buds. [the pics with the black dots, frass.] I made ice hash out of it and it worked like a champ. I followed a tutorial on another forum so I don't think I can post it here but the short and sweet of it is.....
Dryed the tainted buds for about 1.5 weeks. The little worms left when the buds were drying. Once dry, I put in the freezer for a few hours. Then I got a large mason jar and filled with water 3/4's of the way full with icecubes in it aswell, the colder the better. Took the buds out of the freezer and added them to the jar full of ice water and blended the shit out of it with a fork, grinding and mashing away. Then I put the lid on and shook that mofo like a mad man for a few minutes. [your breaking the trichomes off the buds.] Then I let sit for an hour or so. Make sure it stays icecold the entire time. After an hour or so all the tricombs that broke off will sink to the bottom and all the green material and shit will float. Skimmed the surface of the shit and poured off the excess water. When down to the nitty gritty I poured the rest in the coffee filter, scraped the filter, dried in the oven at low temp then rolled into a nice big ball of resin.
Not sure the species of your catipillars or thier poop but on mine, the poop stayed floating with the green material. It's worth a shot if you were going to compost it anyway.
