i fkn hate catepillars!!! also new hairs

plants have been looking good but recently discovered a infestation of catepillars so i bought some catwpillar bt and started going in between the nugs to get the little ruckers out with tweezers. a i there anything i can do save the buds that have catepillar shit on them??couple of buds had to be sacrificed because of stems being torn open and turning brown due to these evil bastards each catepillar i just wanna torture it. any ways this is about the 27th day of flowering and i noticed alot of my pistils are turning brown is this normal and if it isnt what should i do about it most hairs on the buds are like 50/50 white and orange

Try to remove them by hand with a bright cfl to check under leaf or use chemicals doesnt really matter, just get them off as they will probably cause the buds to mold and reduce final weight as they increase and get bigger.
