Pay attention to the version (ingredients)

The old version with 0.82% permethrin, 0.1% pyrethrins, piperonyl butoxide 1% is excellent, the new without piperonyl butoxide (prevents that can recover a non-fatal poisoned insect by enzymatic degradation of the actual poison) no longer. I had here all currently a population of white fly in my wintering quarters for potted plants and the new version of the product was virtually ineffective. A single use of the old means eliminated the problem completely in the shortest possible time. I do not know what you now actually gets but the ingredients are top on the bottle and hopefully agree.
