Yeah it’s definitely too late to apply any bug killer, but maybe you can try biological fighting solutions? Such as using insects that’ll eat that shit (if they exist, i’m not sure).
If you want to smoke that, the best would be to be able to get ride of this by hand, but I think it can be hard and that the taste of your bud is already afected…
I think that even though you thought they were ok to be put in jar, maybe you should have let them a little bit more in your drying room, and with a better ventilation. When I say better, i’m not talking about products, but about ventilation circuit: where the air comes from and where does it leave the room, exactly like a grow room setup!
If you don’t think the problem is there, then just check the humidity you have and make sure to decrease that level with a air dehumidifier or to maintain the level with a Boveda 62.
