I have discovered white flies on pretty much every pepper plant in my yard. I have been trying to spray them all off with the hose with absolutely zero results. Yesterday evening I hit them with some neem oil & I am praying it does the trick. If not I'm going to try a neem oil/soap blend in a few days. I am doing everything in my power to not use poisons. Apparently they love the humidity & heat here. Anyone have any good tips on their eradication?
