You can dust mealworms or superworms and it sticks to it for days. When I leave on Friday for the weekends I dust the worms and place them in the gecko's dish, come back sunday night and the worms are still coated with the Calcium Plus Powder.
That's good to hear, I currently use the rep cal and it doesn't stick to the feeders too good. I only bought the rep cal as it was in the leopard gecko book that I bought.
I'm gonna get some of his stuff as soon as I have some spare cash. It's about $6 or $7 at my local PS
