Happens to all rat block. You can minimize it. Don't throw the bag around and move it little as possible. The powder is created from the blocks rubbing together. Store the bag so the string to open it is on the bottom of the bag. When ready to open the bag, flip it over and open. Then the powder is kind of dispersed throughout the bag. If you raise Dubias, you can use the powder as food for them.
