GH has AzaMax. It's the concentrate of neem oils. We were just fighting two spotted spidermites and losing with dr doom bombs. Guy at hydro store says use this. You spray once then in ten days and then at twenty days. They are gone and eggs are dead. No signs at all. Nice new growth.

When you spray the plants just a litle spritz on the water will take care of larvae too. It does it all and at a real cheap price compared to the damage.
