I cleaned them with my hands . Yesterday was raining and after i went to see them and there was nothing on them might rain take them away . Today ill go again and apply some DE.De works. Citric acid, neem, heck even a mix of isopropyl alcohol water and soap will kill em good. You can wash them off the plants with a good spray of water and then dust de (get a powder sprayer) They'll come back it's not a one and done deal so keep applying until you can no longer see any around. I wouldnt put bugs on an outdoor crop unless it's contained in a greenhouse ... They'll be gone within hours/a day.
