Catapiller shit and thrip damage, to cut out damaged buds or not?

[Cannapheliac]

my plants are about a month in budding and in the past few days they have been ravaged by these lil bastards and I have alot of damage and catapiller shits, I'm afraid if I leave it it will breed fungus and il lose my whole harvest pretty much. So I was thinking of cutting out all the damage and shit on areas of bud because I don't see any other way of being safe.
If anyone has an opinion on what I should do I Would welcome the advice.
