no matter what any label says, dont spray shit the last 10 days AT LEAST... i wouldnt even spray shit the last 2 weeks cuz the labels are fuckin liars!
if i were you i would take buds advice, id go to the hydro place, find the strongest commercial bomb i can.. (best i have found is 4 percent!!) and buy two of em... i would bomb, then treat with tobacco tea every 2 or 3 days for a week, then bomb again and let em go.. dont bother with insectisidal soaps n shit, they are for prolonged treatments and weak sprays too. you need something that will hit em hard, hit em fast, and kill em dead...
once you get your harvest done then you can clean shop and treat your mothers n babies with the pansy sprays n stuff to be a lil easier on em but right now you need to get em good before they take over and kill your shit
