Gargoyle geckos are omnivores that primarily eat a commercial gecko diet (CGD) — a fruit- and protein-based powder mixed with water — supplemented with occasional feeder insects like dubia roaches or crickets, and small amounts of fruit as a treat. Hatchlings and juveniles are typically fed CGD daily with insects offered a couple of times per week, while adults can be fed CGD every two to three days with insects once a week or so. Insects should always be dusted with a calcium supplement, and fresh water should be available at all times even though geckos also drink misted water droplets.
What Gargoyle Geckos Eat in the Wild
Gargoyle geckos (Rhacodactylus auriculatus) are native to New Caledonia, and their wild diet has never been studied in great detail. From field observations and breeder experience, we know they're opportunistic omnivores: insects and other invertebrates, soft ripe fruit and nectar, and occasionally small vertebrate prey such as young geckos or small lizards. This omnivorous, generalist feeding strategy is exactly why gargoyle geckos adapt so well to a captive diet built around commercial gecko food rather than live prey alone — something most pet reptiles can't do.
Commercial Gecko Diet (CGD): The Foundation of Their Diet
The single most important food in a pet gargoyle gecko's diet is commercial gecko diet, sometimes called CGD or meal replacement powder (MRP). This is a fruit-based powder that you mix with water into a paste, and it's formulated to be nutritionally complete on its own — gargoyle geckos are one of the few reptiles that can thrive long-term on a prepared diet without needing live insects at all.
Trusted CGD brands in the gargoyle gecko hobby include Pangea, Repashy (Crested Gecko Diet / Superfoods MRP), and Black Panther Zoological. Most breeders rotate two or three flavors or brands rather than feeding the same one every time — this adds enrichment and a broader spread of nutrients, and geckos tend to eat more readily when given some variety.
| Aspect | Guideline |
|---|---|
| Preparation | Mix powder with water to a smoothie-like consistency, per package instructions |
| Popular brands | Pangea, Repashy, Black Panther Zoological |
| Why it works | Nutritionally complete — covers protein, calcium, and vitamins without insects |
| Leftover food | Remove uneaten portions within 24 hours to prevent mold and fruit flies |
| Variety | Rotate 2–3 flavors/brands for enrichment and nutritional diversity |
Feeder Insects: What and How Often
Live insects aren't required if you're feeding a complete CGD, but most keepers offer them anyway — they add enrichment, hunting stimulation, and a protein boost that can help underweight geckos or breeding females. Across most care guides, insects are offered roughly once to a few times per week, with exact frequency depending on the gecko's age and whether CGD is already meeting its needs.
Good Staple Insects
- Dubia roaches
- Crickets
- Black soldier fly larvae (often sold as "nutrigrubs")
- Superworms (in moderation — see note below)
Occasional Treat Insects
- Waxworms — high in fat, useful for putting weight on a thin gecko but not a staple
- Hornworms — soft-bodied and easy to digest, but very high moisture content can loosen stool if overfed
- Silkworms
Insects should be no larger than the space between your gecko's eyes — oversized prey is a real risk for impaction, especially in juveniles. Only feed insects from a reputable feeder supplier; never feed wild-caught bugs, since they can carry pesticide residue, parasites, or disease.
Before offering insects, it's worth gut-loading them for a day or two with nutritious vegetables or a commercial gut-load product. This passes more nutrition on to your gecko and is a standard practice among breeders.
Fresh Fruit as a Treat
Most commercial gecko diets already contain fruit, so additional fresh fruit isn't necessary — but small amounts make a nice occasional treat. Stick to fruits that lean toward a favorable calcium-to-phosphorus ratio, like mashed banana, mango, papaya, or fig, and keep portions small and infrequent.
Avoid feeding fruit too often: it can dull a gecko's appetite for its nutritionally complete CGD, and some fruits work against calcium balance or cause digestive upset in larger amounts. A few fruits should be avoided entirely or fed extremely rarely — citrus (too acidic), and high-oxalate fruits like starfruit and rhubarb, with rhubarb posing a more serious risk. Avocado should never be fed — it's toxic to gargoyle geckos.
For a full breakdown of safe fruits, portion sizes, and which ones to avoid, see our guide on feeding fruit to gargoyle geckos.
Calcium and Vitamin Supplementation
Calcium is the single most important supplement in a gargoyle gecko's diet, and getting it wrong is the leading cause of metabolic bone disease (MBD) in captive geckos. Most commercial gecko diets already include calcium and vitamin D3, but if you're feeding insects, those insects should be lightly dusted with a calcium supplement at most feedings.
- Without UVB lighting: use a calcium supplement that includes vitamin D3, since your gecko can't synthesize its own.
- With UVB lighting: a calcium supplement without D3 is appropriate, since the gecko is producing its own through UVB exposure.

Feeding Schedule by Age
How often you feed depends heavily on your gecko's age. Younger geckos are growing fast and need more frequent meals; adults do well on a lighter schedule, and skipping an occasional feeding for an adult is healthy rather than harmful.
| Life Stage | Commercial Gecko Diet (CGD) | Feeder Insects |
|---|---|---|
| Hatchlings & juveniles (0–12 months) | Daily, or every other day | 1–2x per week, small/appropriately sized |
| Sub-adults | Every 1–2 days | 1–2x per week |
| Adults (12+ months) | Every 2–3 days | About 1x per week |
| Breeding females | Every other day, or as often as readily eaten | Often increased for condition support |
It's normal — and healthy — for an adult gargoyle gecko to skip a feeding occasionally. This mirrors natural feast-and-famine patterns and helps prevent obesity, which is a common problem in captive geckos that are overfed CGD or treat insects.
Water and Hydration
Gargoyle geckos get a lot of their hydration from daily misting, drinking droplets off enclosure walls, plants, and décor. That said, they can and do recognize and drink from a standing water source, so it's good practice to keep a small, shallow water dish in the enclosure at all times — ideally on a feeding ledge, since gargoyle geckos prefer to eat and drink up off the ground. Clean and refill the dish every few days to prevent bacterial growth.
Foods and Feeding Mistakes to Avoid
- Avocado — toxic, never feed it.
- Citrus fruits — too acidic and generally unpalatable to geckos.
- Starfruit and rhubarb — high oxalate content; rhubarb in particular carries a serious risk and should be avoided entirely.
- Wild-caught insects — risk of pesticide exposure, parasites, and disease.
- Oversized insects — anything wider than the space between your gecko's eyes raises the risk of impaction.
- Dry/dehydrated diets or pellets — gargoyle geckos get much of their moisture from food, so dry pellet-style products aren't a good primary diet.
- Human baby food — not formulated for reptile nutrition and may contain preservatives or additives that aren't appropriate for geckos.
- Overfeeding fruit or fatty treat insects (waxworms, butterworms) — fine occasionally, but a steady diet of these contributes to obesity and can throw off calcium balance.
Frequently Asked Questions
Do gargoyle geckos need live insects to survive?
No. A high-quality commercial gecko diet (CGD) is nutritionally complete on its own, which is part of why gargoyle geckos are such a popular beginner pet — you don't need to keep a live insect colony if you'd rather not. Insects are a beneficial supplement and enrichment tool, not a requirement.
How often should I feed my gargoyle gecko?
Hatchlings and juveniles generally do well with CGD daily or every other day plus insects once or twice a week. Adults typically eat CGD every two to three days with insects around once a week. It's normal for adults to skip an occasional meal.
Can gargoyle geckos eat fruit other than what's in their CGD?
Yes, in small, infrequent amounts — mashed banana, mango, papaya, or fig are good options. Avoid feeding fruit too often, since it can crowd out appetite for their balanced CGD and may unbalance calcium intake.
What insects are best for gargoyle geckos?
Dubia roaches, crickets, and black soldier fly larvae make good staple feeder insects. Waxworms, hornworms, and silkworms are better as occasional treats due to higher fat or moisture content. All insects should be gut-loaded and dusted with calcium.
Is avocado safe for gargoyle geckos?
No. Avocado is toxic to gargoyle geckos and should never be offered under any circumstances.
Do gargoyle geckos need a water bowl if I mist their enclosure?
It's recommended either way. Misting provides hydration through droplets on surfaces, but gargoyle geckos can and do drink from a still water source, so a small, regularly cleaned water dish is good practice as a backup.
