If I am feeding my feeder crickets a high calcium cricket food (purchased at pet store), do I still need to dust them? I feed the high calcium food and also put a mineral block inside their little house. Another issue is knowing for sure they are eating it and eating enough of it when doing it like this. Can the frogs get too much calcium? For example, if my crickets are eating these foods and I dust them, could that be too much for my Whites tree frogs?
