they do more damage than spidermites!, there is no help now its two late in flowering to spray on the buds, iv lost half a crop to them, wait til you start to clip your leaves and you see those damn lil green worms twisted in between you buds, the only thing you can do is look inbetween your buds and use some tweezers and remove any u see, but you have to be quick , because if they see you thell hide back in the bud, and if that doesnt help, harvest the buds with bugs, i know its early but if you dont the worms will ruin them compleatly, it seems every year i grow out doors i run in to those lil fuckers, they love bud more than we do, but early detection will elemate the worms in late flower, the gross thing is when your mancuring your buds and you cant tell from worm guts from the reson on your sissors!,
