Best Insects for Leopard Geckos

Choosing the right insects is one of the most important aspects of leopard gecko care. While these reptiles are hardy and adaptable, not all feeders provide the same nutritional value. Some are excellent staples, while others should only be offered occasionally.

A well-structured insect diet ensures proper protein intake, healthy fat levels, and adequate calcium when combined with supplements. Neglecting variety or relying too heavily on fatty feeders often leads to long-term health issues.

This guide outlines the best insects for leopard geckos, explaining their nutritional benefits, risks, and how to integrate them into a balanced diet. A broader context for these recommendations is covered in the Leopard Gecko Feeding & Nutrition Guide, which explores supplements, gut-loading, and feeding schedules.

Crickets

Crickets are one of the most common feeders for leopard geckos. They are inexpensive, easy to find, and their natural movement stimulates the gecko’s hunting instincts.

• Nutritional value: Good source of protein but lower in calcium compared to other feeders.
• Pros: Affordable, active, and readily accepted by most geckos.
• Cons: Can be noisy, escape easily, and require proper care to stay nutritious.

Because of their naturally low calcium levels, crickets must be gut-loaded with fresh vegetables and grains before feeding. This ensures they pass on essential nutrients to the gecko. Details on proper preparation are explained in the cluster Gut-Loading Feeder Insects, which outlines schedules and safe foods for feeder insects.

Dubia Roaches

Dubia roaches are widely regarded as one of the best staple feeders for leopard geckos. They are quiet, easy to keep, and provide excellent nutrition compared to other insects.

• Nutritional value: High in protein, moderate fat, and a better calcium-to-phosphorus ratio than crickets.
• Pros: Long lifespan, easy to gut-load, and less likely to escape.
• Cons: Not available in every country and may require small colonies for regular feeding.

Dubia roaches are especially useful for growing juveniles and breeding females because of their nutrient density. When rotated with crickets and mealworms, they create a balanced and sustainable feeding plan.

For keepers building a long-term diet strategy, the Feeding & Nutrition Guide explains how to rotate staple feeders like dubia roaches with other insects to maximize health benefits.

Mealworms

Mealworms are another common feeder, often chosen for their availability and low cost. While many geckos readily accept them, they should be used with caution.

• Nutritional value: Moderate protein, higher fat content, and a tough exoskeleton (chitin) that can be harder to digest.
• Pros: Easy to store, inexpensive, and convenient to offer in a feeding dish.
• Cons: Less nutritionally dense than dubia roaches and can contribute to obesity if overused.

Mealworms work best as part of a varied rotation rather than the sole feeder. Over-reliance on them may lead to weight gain and digestive stress. Owners must balance portions and ensure supplementation with calcium and vitamins.

Strategies for avoiding excessive fat intake and maintaining a balanced diet are covered in the cluster Obesity Prevention in Leopard Geckos, which explores safe use of fatty feeders like mealworms and waxworms.

Silkworms

Silkworms are one of the most nutrient-rich feeders available for leopard geckos. Soft-bodied and high in moisture, they are an excellent supplement to a staple diet.

• Nutritional value: High protein, low fat, and naturally rich in calcium.
• Pros: Easy to digest, hydrating, and beneficial for geckos with shedding issues or dehydration risk.
• Cons: More expensive and less widely available than crickets or dubia roaches.

Because they are both nutritious and hydrating, silkworms are especially useful for geckos recovering from illness, dehydration, or poor sheds. Their natural calcium levels also make them a safe feeder for juveniles and breeding females.

Connections between proper hydration, shedding, and feeder choice are further explored in the Shedding & Skin Care hub, which shows how diet and environment work together to prevent stuck shed.

Occasional Treat Feeders (Waxworms, Superworms, Hornworms)

Not all feeders are suitable for daily use. Some insects should be offered only as occasional treats due to their fat content or unbalanced nutrition.

• Waxworms: Extremely fatty and addictive to geckos. Best used sparingly to avoid obesity.
• Superworms: Larger and more active than mealworms, but with higher fat and chitin, which can stress digestion.
• Hornworms: Excellent for hydration and enrichment but not balanced enough for frequent feeding.

These feeders can be helpful in specific situations—such as weight gain for undernourished geckos or as enrichment—but should never replace staple insects like crickets, dubia roaches, or silkworms.

For guidance on balancing treats with staple diets, the Leopard Gecko Feeding & Nutrition Guide explains how to integrate these insects without creating nutritional imbalances.

Conclusion

The choice of feeder insects has a direct impact on the long-term health of leopard geckos. Staple options like crickets, dubia roaches, mealworms, and silkworms provide the foundation of a healthy diet, while fatty feeders such as waxworms or superworms should remain occasional treats.

Variety is key. Relying on a single insect source can lead to nutritional imbalances, while rotating between staples ensures a better mix of protein, fat, and calcium. Preparing insects correctly before feeding is equally important—guidelines for this process are outlined in the cluster Gut-Loading Feeder Insects.

For a complete overview of insect selection, feeding schedules, and supplement routines, the Leopard Gecko Feeding & Nutrition Guide ties all aspects of diet into one framework. With the right balance, geckos remain active, well-nourished, and less prone to common health issues.
