Hi, I have had an infestation of white flies on a very old trumpet vine. Over the past several years, I have tried neem oil, horticultural oil, and pyrethrin. I also tried a systemic product that I put in the soil. Nothing worked.
One remedy that has been suggested is to release 100 DELPHASTUS CATALINAE.
Will I be trading one problem for another? Will do this in the spring if it seems like the right solution.
