If your pet is favoring waxworms over other bugs, try not offering any for a week or two. Waxworms are the juvenile stage of the Greater Wax Moth (Galleria mellonella). These soft-bodied grubs make great treats for reptiles, amphibians, and birds alike!  Nutrition Facts: Moisture — 58.5% Protein — 14.1% Fat — 24.9% Ash — 0.6% Fiber — 3.4% How often can waxworms be offered? Waxworms are naturally high in fat, so they should only be offered as rare treats, never as a regular feeder. If you’re looking for a staple feeder, we recommend dubia roaches and NutriGrubs instead. Always dust waxworms lightly with calcium powder before offering, as they have a high phosphorus content. How to care for waxworms: Waxworms last up to two weeks at room temperature. However, to make them last up to 4 weeks, you can keep them cooler between 50-60 degrees. The best way to do this is with a wine cooler and low humidity.  Do not cool waxworms past 50°F. Remove any blackened dead worms and cocoons daily. If the bedding feels moist when they arrive, take the lid off for a while to let them dry out.
