What Geckos Eat: A Complete Guide to Their Diet (2024)

Geckos are fascinating, agile lizards known for their adhesive toes, vibrant colors, and unique vocalizations. Whether you’re a pet owner, an enthusiast, or just curious about these tiny reptiles, understanding what geckos eat is essential. This comprehensive guide explores the dietary habits of geckos, including what they eat in the wild, what domestic geckos should—including popular staple foods—and tips for providing balanced nutrition.

Natural Diet: What Do Wild Geckos Eat?

Geckos are predominantly insectivorous, but their diet varies depending on the species and habitat. In the wild, these small lizards play a vital role in controlling insect populations.

Common Prey in the Wild:

Small insects: Crickets, flies, moths, and grasshoppers are primary food sources.
Spiders: Many geckos catch and consume spiders, which provide high protein.
Leaners and beetles: These soft-bodied insects are easy targets and nutritious.
Occasional small invertebrates: Some larger gecko species may prey on small centipedes or subsonoids.

Interestingly, some geckos feast on nectar and fruit, especially in tropical regions. Species like the Japanese Whitney’s Leaf-Tailed Gecko and certain African geckos supplement their insect diet with fresh fruit and floral nectar, taking advantage of available plant-based energy sources.

Pet Geckos: What to Feed Your Scaly Friend

If you’re caring for a gecko as a pet—common species include Leopard Geckos, Tokay Geckos, or House Geckos—mimicking their natural diet is key to their health and longevity.

1. Leaf-Tier Insects – The Staple Diet

Commercial gecko diets and cricket blends are convenient, but live insects remain superior:

Crickets (well-grown, gut-loaded)
Mealworms (with properly dusted nutrition)
Dubia roaches (high in protein, low vibratory waste)
Superworms (in moderation; harder to digest)

Tip: Always gut-load insects (feed them nutrient-rich foods 24–48 hours before offered) and dust them with calcium and vitamin supplements at least twice weekly.

2. Occasional Treats

Geckos benefit from occasional variety:

High-protein feeds: Waxworms (rarely, due to high fat), silkworms
Fruit juices and nectar supplements: Applesauce diluted with water (for moisture, not sugar-heavy diets)
Vegetables: Leafy greens like kale or dandelion greens (not a main meal, but good for hydration)

❌ Avoid neglecting protein: Geckos need insect-based nutrition; plant-only diets lead to severe deficiency and shortened lifespans.

Feeding Frequency by Gecko Species and Age

| Gecko Type | Age Range | Feeding Frequency | Diet Notes | |-------------------|--------------------|-------------------|------------| | Juveniles | Hatchling to 6 months | Daily | High-protein insects every day to support rapid growth | | Subadults | 6 months – 2 years | 4–5 times per week | Phase in varied prey and occasional greens | | Adults | 2+ years | 3–4 times weekly | Focus on gut-loaded insects; reduce frequency if overweight |

Special Considerations: Fiber and Hydration

While geckos don’t eat traditional veggies, moisture-rich foods support hydration:

Always provide fresh water in shallow dishes.
Avoid forcing fruits, as their digestive systems struggle with high sugar/juice intake.
Monitor waste—diarrhea or stuck fecals may signal dietary imbalance.

Common Mistakes to Avoid

Feeding wild-caught bugs with pesticides – Always use captive-bred insects or safe outdoor-reared prey.
Overfeeding fat-rich worms – Mealworms andsuperworms should be occasional treats.
Ignoring gut-loading and supplementation – Nutrient-deficient insects starve geckos over time.
Feeding glue, citrus, or toxic foods – These upset digestion or poison.

Conclusion

Understanding what geckos eat empowers responsible pet ownership and conservation awareness. For wild geckos, insect-based diets maintain ecological balance; for pet geckos, a varied yet balanced intake of gut-loaded insects ensures vibrant health and longevity. By replicating their natural feeding habits with proper nutrition, you support these tiny predators thriving, both in nature and in your home.
