A cricket keeper is a plastic container with tubes that extend out. The crickets gather into the tubes. You can powder them easily with calcium/vita D powder and then just tap the end of a tube over your frog tank and out they come. It's easy. I buy crickets every week or two and feed the crickets with gut-loading food and cricket gel water. Then clean out the cricket keep every one to two weeks emptying out all dead crickets and left over food and debris, egg crate and the paper towel I place in the bottom, and wipe everything out. It sounds like a lot of work, but it is really quick and easy. I'll take a picture of mine later. Hope this helps. Just a suggestion.
