does anyone know where to get reasonable quantities of this in powdered form? i'm looking to treat primarily skinks, tortoises and maybe some amphibians, and i figure the paste at lll reptile will only even have a chance of working with the tortoises...it seems like that powder form only comes in huge tubs, does anyone have any advice on how to get some and what to get? best i've heard is to just dust it on their crickets a couple times a week for a few weeks.
