Essential oil-based pesticides work give a much better kill than neem oil. I've never had good results with pyrethrums. The drawback of essential oils is that they tend to strip waxes from leaves and cause phytotoxicity. Circadian Sunrise is an essential oil-based pesticide that mitigates the phytotoxicity problem. It is being used at the UC Davis Conservatory Greenhouses with all their highly sensitive plants and at the UC Davis, Environmental Horticulture Greenhouses. It is OMRI Listed and very safe for users and the environment. It also leaves no harmful residues. Shoot me an email and I will send you some to try.
