Terry, So for me that would be daily and I know they soak each day so they would get a dose of some sort. The NutriBAC, since it's ingested by dusting their food, means they would have to eat and my 2 toads don't eat everyday, their choice, not mine. My 2 frogs usually eat something each day so dusting would work for them. I guess now I just have to decide which way to go. You can get the NutriBAC through Carolina Pet Supply, Quality supplies for raising healthy reptiles I've ordered roaches & butter worms from them and had good service.
