I've tried sand, sprays (pyretherin), I can't use the sticky strips in the grow area itself 'cuz of air movement. Do the dunks work? These fuckers are more a nuisance than anything. I've had 'em since day one this grow. Never had 'em before, but by god, I got 'em now!!!
And these are vacuumed daily!!!
I got them in my cloning area and panicked. I heard they were death on young roots, but I can't kick about the success ratio. I'm sure they can't be good for them, I just don't see a catastrophic crop failure over them. I WOULD like 'em gone, tho....
