Review on Vitamin D3 Free Calcium Supplement for Reptiles by Fluker's by Tomas Webb

Availability Reptiles must be powdered with calcium at each feeding. It is best to take Calcium WITHOUT D3 daily and Calcium WITH D3 once a week. Unfortunately, the pet store chains around me never sell without D3. This stuff is what you need! For crickets/roaches I use a plastic bag and put a little inside. Then I throw my bugs in, shake them up and they're ready to feed. If you buy a lot of crickets and keep them in a cage to feed them, DO NOT dust them beforehand. ONLY before feeding. The reason is that their lungs are underneath and the dust will eventually suffocate them.
