i use a std spray bottle...but once you use it for neem oil it is the neem oil sprayer....typically about 7-10ml/per quart....i use Dutch Master Penetrator to mmix with mine instead of soap but you can use either

spray with neem every 4th or 5th day and mist your plants with plain wter on the other days and that should control your mites

HS NPS active ingredient is dichlorovol and plants do not absorb it ...the warnings are to cover their asses if somebody uses it for breath mints or something:thumbsup:
