Choosing the right nutrition for your crested gecko can feel like a puzzle. Between complete diets, live feeders, and supplemental bugs, it’s easy to wonder if you’re meeting all their needs for a long, vibrant life. Let’s simplify the science and focus on what truly fuels your gecko’s health.
Iām Mo Mahin ā the founder and writer behind Furric. My process involves deep market research into reptile nutrition, analyzing veterinary safety standards for captive insectivores, and evaluating feedback from a community of dedicated crested gecko breeders and pet parents to separate marketing from substance.
This guide cuts through the clutter to help you build a balanced, stimulating feeding plan that supports everything from healthy growth to successful breeding, ensuring you provide the best insects for crested geckos.
How To Choose The Best Insects For Crested Geckos
Crested geckos are omnivorous frugivores, meaning fruit forms the base of their diet, but insect protein is a non-negotiable component for proper development, especially for juveniles and breeding females. The goal is to complement a high-quality complete diet with appropriate feeder insects.
Complete Diets vs. Supplemental Feeders
Premium meal replacement powders (MRPs) from brands like Pangea and Repashy are formulated to be nutritionally complete. They should be your gecko’s dietary staple. Insects, whether live, freeze-dried, or included in MRPs, serve as supplemental protein, enrichment, and a tool for targeted nutrition through dusting. Think of MRPs as the main course and insects as the protein-packed side dish.
Understanding Key Nutritional Needs
For insects, the calcium-to-phosphorus ratio is paramount. You want a ratio of at least 2:1 (Calcium:Phosphorus). Most feeder insects are naturally phosphorus-heavy, which is why “dusting” with a calcium powder is essential. Also, consider fat content; black soldier fly larvae (BSFL) are high in calcium and lower in fat, while waxworms are very high in fat and should be rare treats.
Evaluating Insect Form: Live, Dried, or In Powder
Live insects provide mental stimulation and hunting exercise. Dried insects offer convenience and shelf-stability but lack the moisture and movement that triggers a feeding response. Insect-based MRPs (like fig & insect or grub blends) integrate insect protein directly into the complete diet, which is excellent for geckos that refuse live prey. A combination approach often works best.

Safety & Care Tips
Always Dust & Gut-Load
Feeder insects are naturally deficient in calcium. Before offering any live or dried insect, dust it lightly with a phosphorus-free calcium powder. For live insects, “gut-load” them for 24-48 hours by feeding them nutritious vegetables (like sweet potato, carrots) and commercial gut-load diets to pass those nutrients to your gecko.
Monitor Feeding Response
Crested geckos can be fickle eaters. Offer fresh MRP every other day and remove uneaten portions after 24 hours to prevent spoilage. If your gecko refuses food, try a different flavor or a small live insect to stimulate appetite. Consistent weight checks are more reliable than bowl cleaning as a health gauge.
