This stuff has worked well for me in the dirt around the stalk, like if they get out of control. I used it for other pests In the past as a pre treat when I had some in the ground. And I have dusted it on them , they look liked shit for days until it all washed off


Says it works on caterpillars too. I used it for grasshoppers or something back then , it Worked well . It's a powder aka dust. If picking them off manually isn't an option. I don't know what pest control practice is for cannabis . Other than use nothing if possible but sometimes you just need help. I smoked that plant when I finally got it thru its issues well after I dusted it and I'm not dead so that's a plus

So I just use manual intervention or stuff that is ok to use on food I eat.
