Would it be any different than dusting crickets with calcium? I spray our geckos with liquid calcium every day, about 9 drops to a 1/2 cup of water in a pump sprayer. They've been alive for a couple of years now. We even have a baby one now and its doing fine also. I was afraid that they would not eat the crickets before the dust wore off so I started doing the spray and no problems. We are just getting ready to get a cham so I'd really like to know also. Anyone?
