something with the active ingredient of - pyrethrins / pyrethrines? ... even if slightly different spelling will be same type of molecule.. it breaks down in 2-3 days. it is a kill on contact option. sticky traps are also a good idea. it's always best to kill in multiple ways and preferably at mutliple stages of life -- with thrips i don't know of any produt that specifically targets their eggs/larva though. i don't think their eggs are in the substrate. Always scary using any product, even if listed as harmless, on flowering plants, but at least this one breaksdown very fast and you look to be very early in flower, so i'd use it to save a harvest in that context, but you'll have to make that choice. if you have real neem oil, that'll be fairly effective too... if it is "clarified" it is missing teh avtive ingredient that messes with their nervous systems. azadirachtin or similar spelling.. if that is not listed in teh active ingredients, then it is clarified... clarified has virtually no health impacts and is safe(r) to use than real neem oil, but also less effective. it's more akin to a horticultural oil - which does offer some benefits. it's still unpleasant for insects, and can be a deterrent but alone will not be effective. breaks down to harmless things within 14-21 days.
