T-Rex Cricket Diet Dust ILF is the perfect gut-loader for your crickets. It is a nutrient, mineral, protein, and vitamin rich balanced diet designed to increase the nutritional value of insects before they are fed. This powder will be gobbled up by the crickets for immediate delivery into your pet. The cricket then becomes the perfect, well-rounded meal. Cricket Diet Dust is recommended that it be used in conjunction with T-Rex Calcium Plus products to maximize the nutrition of feeder insects.
