Haha, Just kidding. I use pyrethum to kill whats there and then Azatrol to prevent new eggs and pest. Azatrol is great because it messes with the bugs hormones and prevents them from reproducing. Had a big spidermite problem last year and it worked wonders. A little bottle is around 20 bucks, but its super concentrated and you just use a very little bit diluted in a water spray bottle, so it last a very long time. I would stop using any type of pest control at least 3 weeks before harvest or your gonna be smoking chemicals.
Diatemacious earth works great and I think I got it for 15-20 bucks for 25 lb bucket. Havnt seen a single insect on the plant I pit outdoors. Mix it in the dirt or top dress. It shreds insects up. I can vouche for it!
