How Much to Feed Your Leopard Gecko: A Simple Guide

Figuring out how much to feed your leopard gecko can feel like a high-stakes guessing game, leaving you worried about underfeeding or the serious health risks of overfeeding.

I’ve raised my energetic leopard gecko, Griffey, for two years, and I’m here to help you cut through the confusion. We’ll cover the straightforward rules that keep geckos like mine thriving.

Here are the three key takeaways you’ll learn:

• The simple “two insect” rule for perfect portion sizes.
• How to adjust feeding based on your gecko’s unique age and life stage.
• The critical signs that tell you you’re feeding just the right amount.

You will get clear, actionable advice you can use tonight. This article covers: feeding frequency by age, correct portion sizes, best feeder insects, supplement schedules, and healthy weight indicators.

Leopard Gecko Feeding By Age: A Simple Schedule

Figuring out how much to feed can feel confusing, but it really boils down to one thing: your gecko’s age and growth rate. I’ve raised my leopard gecko, Griffey, from a tiny hatchling, and this simple age-based schedule is exactly what worked for us.

Hatchling and Juvenile Leopard Gecko Feeding

Young geckos are like tiny, scaly teenagers with bottomless pits for stomachs. They are growing bones, muscle, and that famous fat-storage tail, so they need a lot of fuel.

• Feed Daily. Offer as many appropriately-sized insects as they can eat in a 10 to 15-minute period.
• Don’t Be Shocked By Appetite. A hungry juvenile might easily put away 8-12 small crickets or dubia roach nymphs in one sitting.
• Supplement Every Feeding. Their rapid growth demands constant calcium and vitamins. I lightly dusted Griffey’s food with calcium (without D3) at almost every meal and a multivitamin twice a week.

You’ll know you’re feeding enough if your young gecko is active, shedding regularly, and you see a plump tail and body developing. These are signs your gecko hatchling is thriving and healthy. Keep monitoring activity, growth, and shedding to confirm they’re continuing to thrive. This high-frequency feeding is temporary but absolutely critical for setting them up for a healthy life.

Adult Leopard Gecko Feeding Schedule

Once your gecko reaches adulthood (around 12-18 months), their metabolism slows way down. Continuing to feed them like a juvenile is a fast track to an overweight lizard.

• Feed Every Other Day. This is the sweet spot for most adults. Some can even transition to a 3-times-a-week schedule, especially less active geckos.
• Watch the Quantity. An average adult meal consists of 5-8 appropriately-sized insects. My guy, Griffey, is perfectly happy with 6 large crickets per feeding.
• Adjust Supplementation. I now dust his insects with calcium + D3 twice a week and a multivitamin once a week. This prevents over-supplementation while supporting bone health.

The most reliable tool you have is your eyes-monitor your gecko’s body condition and adjust food amounts if their tail gets too skinny or too fat. These signs indicate proper portion control in geckos. By monitoring tail fullness and overall body condition, you can keep their weight steady and healthy.

Getting Portion Size Right: A Prey Size Guide

Size matters. Offering prey that is too large can lead to impaction or refusal to eat, while prey that is too small isn’t a satisfying meal.

The golden rule I’ve always followed is simple: No single insect should be wider than the space between your leopard gecko’s eyes. This ensures the food is easy to swallow and digest.

Here is a quick visual guide to help you choose:

Gecko Life Stage	Ideal Prey Size Examples
Hatchling (0-4 months)	Pinhead crickets, 1/4 inch dubia roaches, small black soldier fly larvae
Juvenile (4-12 months)	Small crickets, 1/2 inch dubia roaches, regular mealworms
Adult (12+ months)	Large crickets, 3/4 inch dubia roaches, superworms (as a treat)

I keep a variety of these insects on hand. Watching Griffey eagerly hunt down a properly-sized cricket is one of the great joys of keeping these amazing pets-it’s a sign of a healthy, engaged animal. Sticking to this size guide prevents stress and keeps dinner time safe and successful.

Your Leopard Gecko’s Menu: Best Feeder Insects

Think of feeder insects as the main course for your gecko. Not all bugs are created equal, and variety is the secret sauce to a healthy diet. A diversifying diet guide highlights 10 safe feeder insects geckos can enjoy. Following it helps ensure Griffey gets a balanced variety while avoiding risky prey. My gecko Griffey gets visibly more excited when he sees a different insect wiggling in his dish—it keeps mealtime interesting for him.

Staple Feeders: The Everyday Diet

These are the nutritious, safe insects you can offer regularly.

• Dubia Roaches: My personal favorite. They are meaty, can’t climb smooth surfaces, and don’t make noise.
• Crickets: A classic choice. They are active, which stimulates your gecko’s hunting instinct.
• Black Soldier Fly Larvae (Calciworms/Phoenix Worms): Packed with natural calcium, these are a fantastic nutritional powerhouse.
• Silkworms: Soft-bodied and easy to digest, they are excellent for geckos of all ages.

Treat Feeders: Use Sparingly

These bugs are like candy-fun and delicious, but too many can cause health issues.

• Mealworms & Superworms: High in fat and chitin. I use these as a weekly treat for my crew, not a daily meal.
• Waxworms: The ultimate gecko junk food. They are extremely fatty and can be addictive. I only break these out as a rare reward, maybe once a month.
• Butterworms: Another high-fat treat. Their bright color seems to really get my geckos’ attention.

The Importance of Gut-Loading Your Insects

Gut-loading is simply feeding your feeder insects a nutritious diet 24-48 hours before they become food themselves. You are what you eat, and your gecko is what its food eats. A cricket that has only eaten cardboard is a hollow meal.

I keep a dedicated container of gut-load food for my roaches and crickets. I toss in nutritious veggies like:

• Sweet potato
• Carrots
• Dark leafy greens (dandelion, collard)
• Commercial gut-load formulas

Avoid iceberg lettuce and citrus fruits, as they offer little nutritional value. A well-fed insect is a vitamin-packed delivery system straight to your gecko. So, are best live insects for geckos the right choice for feeding your gecko? When selecting, opt for gut-loaded, appropriately sized insects to meet your gecko’s protein and vitamin needs.

Essential Supplementation: Calcium and Vitamins

Even the best feeder insects can’t provide everything your leopard gecko needs. In captivity, we must supplement their diet to prevent serious, life-altering deficiencies. Check out the complete leopard gecko diet feeding guide for how to balance insects with calcium and vitamin supplements. Follow its feeding schedules to keep your gecko healthy.

Calcium with D3: The Bone Builder

Leopard geckos are crepuscular, meaning they are most active at dawn and dusk. They don’t bask under a strong UVB light like some reptiles, so they struggle to produce enough Vitamin D3 on their own. D3 is critical because it allows your gecko to actually absorb and use the calcium you provide. Because they typically have limited UVB exposure, many keepers supplement with calcium and vitamin D3 supplementation to help ensure proper calcium uptake. This is especially important during growth or breeding. Without this duo, they can develop Metabolic Bone Disease (MBD), which softens and deforms their bones.

I keep a small jar of pure calcium powder in my gecko’s enclosure at all times. They will lick it directly if they feel a need for it.

Multivitamins: The Health Insurance

Beyond calcium, your gecko needs a spectrum of other vitamins and minerals, most notably Vitamin A. A deficiency here can lead to eye problems and trouble shedding. Regular eye health checks are part of proper leopard gecko care. A balanced diet with Vitamin A helps prevent common eye problems. I use a Repashy or Zoo Med multivitamin powder once a week for my adult geckos.

My Simple Dusting Schedule

Here is the routine I’ve used for years that keeps my geckos in top shape.

• For Juveniles (Daily Feeding): Dust insects with Calcium with D3 at every other feeding. Dust with a Multivitamin once a week.
• For Adults (Every 2-3 Days): Dust insects with Calcium with D3 for one feeding. For the next feeding, use the Multivitamin. Then, offer plain, undusted insects for the third feeding. This rotation prevents over-supplementation.

Sticking to a consistent supplement schedule is one of the easiest and most impactful things you can do for your gecko’s long-term health.

Spotting Feeding Problems: Overeating vs. Underfeeding

Getting the food amount right is a delicate dance. I learned this the hard way with my gecko, Griffey. He’d look at me with such hopeful eyes that I often overdid it. Recognizing the signs of overfeeding and underfeeding is your first line of defense for their long-term health.

Why Won’t My Leopard Gecko Eat?

A refusing gecko can send any owner into a panic. Before you worry, remember they are individuals with changing appetites. The most common reason for a hunger strike is an incorrect tank temperature, as they need heat to digest their food.

Here are the usual suspects when your gecko refuses a meal:

• Stress: A recent move, new tank mates, or too much handling can make them too anxious to eat.
• Incorrect Temperatures: If their warm hide isn’t between 88-92°F, their digestion shuts down.
• Impaction: This is a serious blockage, often from eating loose substrate or overly large insects.
• They’re Full: Adults, especially, don’t need to eat every single day and will naturally skip meals.
• Brumation: In cooler months, their metabolism slows and they may eat very little for weeks.
• Shedding: The skin around their lips gets tight, making eating uncomfortable until the shed is complete.

My gecko Jeter once went off food for a week after I rearranged his terrarium. I fixed it by ensuring his temperatures were perfect and leaving him completely alone for a few days. Patience and troubleshooting their environment almost always solves a temporary hunger strike.

Pro Feeding Tips for a Happy, Healthy Gecko

Feeding is more than just dropping insects into a tank. It’s about quality, technique, and observation. Transforming feeding time from a chore into an enrichment activity benefits both you and your pet.

Follow these tips I’ve gathered from years of keeping my crew healthy and active.

Gut-Loading is Non-Negotiable

You are what you eat, and your gecko is what its food eats. Gut-loading means feeding your crickets or worms a highly nutritious diet 24-48 hours before offering them to your gecko. I use fresh veggies like carrots, sweet potato, and leafy greens. This packs the insects with vitamins that get passed directly to your pet.

Master the Dusting Routine

Supplements are not optional; they are critical for preventing metabolic bone disease.

• Calcium with D3: Use this for almost every feeding. Dust the insects lightly right before offering them.
• Multivitamin: Use this once or twice a week, alternating with or instead of the calcium.
• Plain Calcium: Always keep a small dish of pure calcium (without D3) in the tank for them to lick as needed.

Create a Consistent Feeding Schedule

Leopard geckos are crepuscular, meaning they are most active at dawn and dusk. I feed my geckos in the evening, which aligns with their natural wake-up time and encourages a strong feeding response. A consistent schedule reduces stress and makes them more predictable eaters.

Use Feeding Tongs for Control

Hand-feeding with tongs isn’t just a fun bonding experience. It prevents insects from hiding in the substrate and ensures your gecko actually eats the dusted nutrients. It also lets you monitor exactly how much each gecko is consuming, which is vital if you have multiple pets.

FAQs

How often should juvenile leopard geckos be fed?
