GMSgrowsanswered grow question 4 years ago Any bugs die with soap and water, and it is safe to use and control. Best to have a pump up weed sprayer with a wand. Mix about 10 parts water to 1 part dawn dish soap. Make sure to spray the undersides of every leaf and the spray the top sides. Do this a few minutes before lights out. Repeat every 3 or 4 days for a couple weeks. Keep an eye for bugs and repeat as necessary. It's also a good foliar feed. Cheers
