I just wanted to thank Monterey insect spray with spinosad concentrate for wiping out my Thrip infestation. I didn't have time to see if Triple AG neem oil from Home Depot or if Dr.Bronners Castile soap will work. Also, a shout down to Jorge Cervantes' revised edition of Indoor Marijuana Horticulture 1993'. In that guide I read that Thrips are uncommon indoors! So I got caterpillar spray, etc. I had the golden/ yellow thrips. I controlled them with a high alcohol content dishwater spray, til they got somewhat immune to it. Hail Spinosad!
