Leopard Gecko Feeders

Live Feeder Insects for Leopard Geckos — The Complete Feeding Guide

Leopard geckos are strict insectivores — they eat only live insects, which makes choosing the right feeders critically important. Unlike bearded dragons that supplement their diet with vegetables, or blue tongue skinks that eat an omnivore mix, leopard geckos get 100% of their nutrition from the insects you provide. Every feeder choice directly impacts their calcium intake, fat balance, hydration, and long-term health. At All Angles Creatures, we offer a curated selection of feeder insects perfectly sized and nutritionally balanced for leopard geckos at every life stage.

Understanding Leopard Gecko Nutrition

Leopard geckos need a diet high in protein and moderate in fat, with consistent calcium supplementation to prevent metabolic bone disease (MBD) — the most common nutritional disorder in captive leos. Because 100% of their nutrition comes from insects, gut-loading and variety are even more essential than for omnivorous species. A rotation of 3-4 feeder types, properly supplemented, is the foundation of excellent leo nutrition.

Two of the biggest nutritional challenges for leopard gecko keepers are obesity (leos store excess fat in their tails, and many captive leos are dramatically overweight) and calcium deficiency (most feeder insects contain more phosphorus than calcium). The feeding rotation below addresses both: lean protein from roaches, ultra-low-fat supplementation from silkworms, and natural calcium from BSFL.

Life Stage Recommended Feeders Frequency Insects per Session
Hatchling/Juvenile (0-6 mo) Small roach nymphs, small silkworms, BSFL Daily 5-8
Sub-adult (6-12 mo) Small-medium roaches, silkworms, BSFL, mealworms Every other day 5-8
Adult (12+ mo) Medium roaches, silkworms, BSFL, hornworms, mealworms Every 2-3 days 5-8

Best Feeders for Leopard Geckos

Discoid Roach Nymphs — The Protein Staple

Protein: ~20% | Fat: ~7% | Ca:P: 0.77:1

Small to medium discoid roach nymphs are our top recommendation for leopard geckos. They deliver the highest protein of any common feeder at a moderate fat level safe for regular feeding. They move at the perfect speed for leos to hunt — slow enough to catch easily but active enough to trigger the feeding instinct. They cannot climb glass or plastic enclosure walls, so they stay on the floor where your gecko hunts. They do not bite, do not smell, and do not make noise. And they gut-load exceptionally well, holding nutrients from their last meal for 24-48 hours.

Most adult leopard geckos should eat medium discoid roaches — they are large enough to be nutritionally meaningful but small enough to consume safely. Juveniles should stick to small nymphs. Most adult leos should not eat large adult discoid roaches — they are simply too big for the average leo's mouth.

Silkworms — Ultra-Low-Fat Supplement

Protein: ~9% | Fat: ~1% | Moisture: ~83% | Chitin: None

Silkworms are one of the best supplemental feeders for leopard geckos — at 1% fat, they deliver lean nutrition without contributing to the tail obesity that plagues so many captive leos. Their 83% moisture supports hydration in these desert-adapted animals that often do not drink reliably from water dishes. Their completely soft, chitin-free body eliminates the impaction concerns that come with tougher feeders like mealworms. And they contain the unique serrapeptase enzyme that may support digestive and immune health.

Silkworms are also one of the most effective feeders for picky leos. Leopard geckos raised exclusively on mealworms sometimes develop "mealworm fixation" — refusing everything else. Silkworms, with their unique pale appearance and slow wriggling movement, often break through this fixation where other feeders fail.

Black Soldier Fly Larvae (BSFL) — The Calcium Powerhouse

Calcium: ~9,340 mg/kg | Ca:P: 6.92:1 | No dusting required

BSFL are the most important calcium supplement you can offer your leopard gecko. At 9,340 mg/kg calcium — 311 times more than mealworms — they deliver a calcium surplus that actively builds bone density and prevents MBD. They are the only feeder insect that does not require calcium dusting. For juvenile leos during rapid bone growth and adult females producing eggs, BSFL provide a calcium safety net that no other feeder can match.

Some leos initially ignore BSFL because they are less active than roaches. Try offering in a small dish where concentrated wriggling is more visible, or mix with roach nymphs in the same dish. Most leos accept BSFL within 1-3 offerings.

Mealworms — Convenient but Limited

Protein: ~20% | Fat: ~13% | Ca:P: 0.04:1

Mealworms are the classic leopard gecko feeder — easy to store in the fridge, cheap, and loved by most leos. However, their 13% fat is nearly double that of discoid roaches, their Ca:P ratio of 0.04:1 is among the worst of any feeder (25 times more phosphorus than calcium), and their tough chitin exoskeleton poses impaction risk for juveniles. We recommend mealworms as an occasional supplement (1-2 times per week for adults) rather than a daily staple. Never use mealworms as the sole feeder — the fat and calcium profile will cause health problems long-term.

Hornworms — Hydration Treat

Moisture: ~85% | Ca:P: 3.07:1 | Fat: ~3%

Hornworms provide exceptional hydration (85% moisture) and excellent calcium (3:1 Ca:P). Offer 1 small hornworm per feeding, 1-2 times per week. Leopard geckos are small — a single hornworm is a full treat serving. Only use small hornworms for leos. Hornworms grow fast, so use promptly or refrigerate at 50-55°F to slow growth.

Sizing Rule

Never offer a feeder insect wider than the space between your leopard gecko's eyes. This prevents choking and impaction — risks that leopard geckos are particularly susceptible to due to their relatively small mouths and the fact that they swallow prey items whole or in large pieces.

Calcium Supplementation Strategy

Leopard geckos need calcium at every feeding — their strict insectivore diet provides no vegetable calcium sources, making supplementation essential:

  • Every feeding: Dust staple feeders (roaches, silkworms, mealworms) with calcium + D3 powder
  • 1-2x/week: Offer BSFL — no dusting needed, natural calcium
  • Once weekly: Dust with multivitamin for broad-spectrum coverage
  • Always available: Keep a small dish of plain calcium powder in the enclosure — many leos voluntarily lick it when they need extra calcium. This is a unique and valuable self-regulation behavior.

The Ideal Leo Feeding Week (Adult)

This rotation provides protein (roaches), calcium (BSFL), low-fat nutrition (silkworms), hydration (hornworm), and variety (mealworms as occasional supplement) — covering every nutritional base across the week.

Signs of Overfeeding

Monitor your leopard gecko's tail width relative to its head. A healthy leo tail is plump but not wider than the head. If the tail becomes excessively fat, the belly hangs when walking, or the armpits show fat bubbles (armpit bubbles), reduce feeding frequency and shift toward leaner feeders like silkworms. Leopard gecko obesity is one of the most common health issues in the hobby — and it is entirely preventable through proper portioning and feeder selection.
