No , I used to when I started off keeping my BTS and then got Rex and Puff, it was going onto the crickets and greens and veg/pellets mix.
I found out this might lead to overdosing with calcium and vitamins so I stopped, it's just a LIGHT dusting on the crickets , and I add the residue dust to the bran the mealworms and superworms are in (so they get it mixed with the bran, carrots and greens/whites).
