How to Feed Leopard Geckos for a Healthy Life

A leopard gecko that eagerly watches a feeder insect, stalks it, and strikes is doing more than putting on a good show. That hunting behavior is part of healthy husbandry. Knowing how to feed leopard geckos means offering the right prey, in the right amount, with dependable calcium support and a habitat warm enough for digestion. Get those pieces working together, and feeding becomes one of the easiest ways to support The Best Life for your gecko.

Leopard geckos need live, insect-based food

Leopard geckos are insectivores. Their diet should center on appropriately sized live feeder insects, not pellets, vegetables, fruit, meat, or table scraps. A little variety helps provide a broader nutritional profile and prevents your gecko from becoming fixated on one favorite prey item.

Crickets, dubia roaches, black soldier fly larvae, silkworms, and mealworms can all have a place in a well-managed rotation. Each option has trade-offs. Crickets are active and can encourage a strong hunting response, but loose crickets should not remain in the enclosure after feeding. Dubia roaches are nutritious, quiet, and easy for many keepers to contain, though availability can vary. Mealworms are convenient in a smooth-sided dish but are richer and should not become the only feeder for most geckos.

Waxworms and butterworms are best treated like dessert: useful for tempting a reluctant eater or helping a thin gecko under veterinary direction, but too fatty for routine meals. Hornworms are highly hydrating and usually popular, yet they grow quickly and can become too large for smaller geckos.

Choose feeders that are no wider than the space between your gecko's eyes. This simple rule reduces the risk of feeding prey that is difficult to swallow or digest. For a young hatchling, that means very small insects. Adults can manage larger prey, but “larger” is not automatically better.

How to feed leopard geckos at each age

Age, body condition, activity level, reproductive status, and seasonal behavior all affect appetite. The schedule below is a useful starting point, not a reason to ignore what your individual gecko is telling you.

| Life stage | Typical feeding rhythm | Starting portion |
|---|---|---|
| Hatchling to 6 months | Daily | Offer small insects for 10-15 minutes, or roughly 5-10 appropriately sized prey items |
| Juvenile, 6-12 months | Every other day | Offer a moderate meal and adjust for growth and body condition |
| Healthy adult | 2-3 times weekly | Start with 5-10 suitable insects per meal, then adjust as needed |

For active feeders, a short supervised feeding session works well. Offer insects one at a time with feeding tongs or place them in a feeder dish when appropriate. Stop when your gecko loses interest. Some adults eat several insects at one meal and very little at the next. That can be normal.

A gecko's tail is a better guide than a rigid feeder count. A healthy tail should look rounded and substantial, but not dramatically wider than the neck or body. A tail that is thinning, a visible spine, ongoing weight loss, or a complete loss of appetite deserves attention. On the other hand, an overly plump gecko may need smaller meals, lower-fat feeders, and a conversation with an experienced reptile veterinarian.

Gut-load feeders before they become dinner

The nutritional value of feeder insects depends heavily on what those insects have eaten. Gut-loading means feeding your insects a quality, nutrient-dense diet for at least 24 to 48 hours before offering them to your gecko. This is one of the most practical habits a keeper can build.

Use a reputable commercial gut-load or a fresh, species-appropriate feeder diet. Many keepers pair a dry gut-load with moisture-rich produce such as leafy greens, squash, or carrots for the insects. Remove anything that spoils quickly. Feeders should also be kept clean, appropriately housed, and hydrated before use.

Avoid collecting insects outdoors for your leopard gecko. Wild bugs can carry pesticides, parasites, or other contaminants, even if the area looks safe. Captive-raised live feeders give you far more control over size, freshness, and nutrition.

Calcium, vitamin D3, and multivitamins matter

Even a varied insect menu is naturally low in calcium. Without proper supplementation, leopard geckos can develop serious bone and muscle problems, including metabolic bone disease. Feeding insects that have been lightly dusted with a reptile calcium powder is a normal part of responsible care.

Keep a small dish of plain calcium without phosphorus in the enclosure so your gecko can use it as needed. Many keepers also dust feeders with plain calcium regularly, while using calcium with vitamin D3 and a reptile multivitamin on a less frequent schedule. The exact frequency depends on your gecko's age, the product directions, whether you provide appropriate UVB lighting, and veterinary guidance.

This is an area where more is not always better. Too little supplementation creates risk, but overdoing vitamin D3 or vitamins can also cause harm. Follow the label for your supplement, avoid stacking several fortified products without a plan, and ask a reptile veterinarian for individualized guidance if your gecko is growing, breeding, recovering from illness, or showing unusual symptoms.

Feed at the right time and keep water available

Leopard geckos are generally most alert in the evening. Offering food in the late afternoon or evening often matches their natural activity pattern and gives you a better chance to observe appetite, movement, and stool quality.

Fresh, clean water should always be available in a shallow, sturdy dish. Replace it daily and clean the dish often. Leopard geckos also benefit from a humid hide, especially during shedding, but a humid hide is not a substitute for drinking water.

Temperature has a direct effect on digestion. If the warm side of the enclosure is too cool, your gecko may eat poorly or struggle to process meals. Provide a proper warm hide, a cooler retreat, thermostatically controlled heating, and temperatures verified with reliable thermometers. Feeding heavily when temperatures are off can create problems that look like picky eating but are really husbandry issues.

What to do when your leopard gecko will not eat

A missed meal is not automatically an emergency, particularly for a healthy adult. Adults may eat less during winter slowdowns, after a move, during shedding, or when exposed to breeding activity. Females carrying eggs may also change their eating habits.

Start by checking the basics: enclosure temperatures, access to hides, fresh water, prey size, supplement routine, and whether the feeder insect is moving naturally. Stress from too much handling, a bare enclosure, loud activity, or a new habitat can suppress appetite as well.

Do not leave crickets or other roaming insects loose in the enclosure overnight. They can bother or bite a resting gecko, and you lose track of what was actually eaten. Remove uneaten feeders after the session and try again at the next appropriate meal.

Contact a qualified reptile veterinarian promptly if appetite loss comes with weight loss, a shrinking tail, lethargy, diarrhea, constipation, regurgitation, swelling, weakness, or abnormal movement. Young geckos and visibly thin geckos have less room for a wait-and-see approach.

Make feeding a calm routine

A simple routine is easier to maintain than a complicated one. Keep a few reliable feeder options, gut-load them, dust them according to a sensible supplement plan, and observe your gecko while it eats. A small kitchen scale and a weekly weight log can reveal changes long before they become obvious by eye.

At Walnut Creek Supply, we believe good husbandry is built from those everyday choices: clean water, quality live feed, a secure habitat, and an owner who notices the details. Your leopard gecko does not need a trendy menu. It needs consistent, species-appropriate care and a patient keeper willing to adjust when its needs change.
