Prevention is the best cure. Well I prevented nothing and now i have about 11.5*10^3 aphids on my growing site. I think they are comming from a zucchini plant nearby which i constantly treat for aphids but it is too dense. I have kept all the chili safe from the little green buggers. But whenever I come around to the plants I have to pluck off/spray off winged aphids. Is there a preventive remedy that can help me. What I want is to keep the aphids off. Maybe mosquito net over the plants?
