i know for sure i have fungus gnats flying around and i probably still have thrips, my flowering plants were too big for me to eradicate them. spent like a month spraying every 2 days. sometimes every day and multiple times a day.
i'm going to order some nematodes and get a friend to grab me spinosad spray while he's in the states this weekend. i didn't find method 1 to be very effective so i'll probably just get essential oils and make my own insecticidal soap. slap up some sticky traps and see what's what.
once i harvest the last 2 plants in a couple weeks i'll be able to fully spray down and clean the tent and dunk/submerge the lil guys in a solution. hopefully eradicate these buggers and maintain a strict IPM schedule and never deal with this again!!
