House geckos thrive on a diet of live insects, supplemented with calcium and vitamins for optimal health.
Understanding the Nutritional Needs of House Geckos
House geckos are insectivorous reptiles that require a diet rich in protein to support their active lifestyles and rapid growth. Their natural diet consists primarily of live insects, which provide essential nutrients including proteins, fats, and trace minerals. Unlike many other pets, house geckos cannot digest plant matter effectively, so feeding them fruits or vegetables is not recommended.
Protein is the cornerstone of their diet, as it fuels muscle development, energy production, and overall cellular function. Calcium and vitamin D3 are equally crucial to prevent metabolic bone disease, a common ailment in captive reptiles. Proper supplementation ensures strong bones and healthy physiological processes.
Hydration also plays a subtle but important role. While geckos absorb moisture from their prey, providing a shallow water dish or misting their enclosure helps maintain hydration and supports shedding.
Top Live Insects to Feed Your House Gecko
Live prey stimulates natural hunting behavior, keeps your gecko physically active, and offers balanced nutrition. Here are the best insects to feed a house gecko regularly:
Crickets are the most popular feeder insect for house geckos. They are readily available, easy to breed, and packed with protein. Their size can be matched to the gecko’s age — smaller crickets for juveniles and larger ones for adults. Before feeding, dust crickets with calcium powder to boost nutrient intake.
Mealworms are a convenient staple, offering moderate protein and fat content. They have a harder exoskeleton, so they should be fed sparingly to avoid digestive issues. Mealworms can be gut-loaded (fed nutritious food before being offered) to enhance their nutritional value.
Ideal for hatchlings and small geckos, fruit flies are tiny but nutrient-dense. They encourage natural hunting instincts in young geckos and provide a good source of protein without overwhelming their small digestive systems.
Waxworms are high in fat and should be considered an occasional treat rather than a staple. Overfeeding waxworms can lead to obesity and health problems.
Essential Supplements for House Gecko Diets
Live insects alone don’t supply all the nutrients your gecko needs. Supplementation is key to preventing deficiencies and promoting longevity.
- Calcium Powder: Dust feeder insects with calcium powder before feeding at least three times a week to maintain bone strength.
- Vitamin D3: Vital for calcium absorption, vitamin D3 supplements should be given periodically unless your gecko receives adequate UVB lighting.
- Multivitamins: A reptile-specific multivitamin once or twice a week ensures your gecko receives trace minerals and vitamins not found in feeder insects.
These supplements can be sprinkled on insects or added as a powder coating, ensuring your pet gets balanced nutrition in every meal.
Feeding Frequency and Portion Sizes
The feeding schedule depends on your gecko’s age, size, and activity level:
- Hatchlings and Juveniles: Require daily feeding with smaller prey items like fruit flies or pinhead crickets to support rapid growth.
- Sub-adults: Feed every other day with medium-sized crickets or mealworms.
- Adults: Feeding 2-3 times per week is sufficient, focusing on larger crickets or mealworms.
Avoid overfeeding; leftover prey can stress or harm your gecko if left in the enclosure. Remove uneaten insects promptly.
Safe Foods to Avoid and Foods to Never Feed
Not all insects or foods are safe for house geckos. Some may carry parasites, toxins, or cause digestive upset.
Insects to Avoid
- Aphids: Often sprayed with pesticides, aphids can be harmful.
- Wild-caught insects: These may carry parasites or pesticides.
- Fireflies: Toxic to reptiles due to chemical defenses.
- Cockroaches from unknown sources: Potential carriers of disease.
Foods Never to Feed
- Dairy products: Geckos lack enzymes to digest lactose.
- Fruits and vegetables: Not part of their natural diet and difficult to digest.
- Processed human food: Contains harmful additives and lacks necessary nutrients.
Sticking with safe, live feeder insects ensures your gecko’s health remains uncompromised.
The Role of Gut-Loading in Enhancing Nutrition
Gut-loading means feeding nutritious food to insects before offering them as prey. This process boosts the nutritional content of feeder insects, making them healthier for your gecko.
Common gut-loading foods include:
- Leafy greens: Kale, collard greens, and dandelion leaves provide vitamins.
- Vegetables: Carrots, squash, and sweet potatoes add fiber and vitamins.
- Commercial gut-load formulas: Specially formulated powders designed for feeder insects.
Insects that are gut-loaded carry these nutrients internally, passing them on to your gecko when eaten. Feeding gut-loaded insects is a simple way to improve your pet’s diet without extra effort.
Nutritional Comparison Table of Common Feeder Insects
| Insect | Protein (%) | Fat (%) |
|---|---|---|
| Crickets | 65-70% | 15-20% |
| Mealworms | 50-55% | 25-30% |
| Fruit Flies | 60-65% | 10-15% |
| Waxworms | 15-20% | 60-65% |
This table highlights why crickets are often preferred for balanced nutrition, while waxworms should be limited due to their high fat content.
The Importance of Hydration in Diet
Although house geckos get moisture from their prey, they still need accessible water sources. Providing a shallow water dish encourages drinking behavior and helps maintain hydration. Misting the enclosure lightly once or twice a day also helps replicate natural humidity levels, aiding in shedding and respiratory health.
Dehydration can lead to lethargy, shedding problems, and severe health issues. Watch for signs such as sunken eyes or dry skin as indicators your gecko needs more moisture.
Troubleshooting Feeding Problems in House Geckos
Sometimes house geckos may refuse food or show signs of poor health related to diet. Common causes include stress, illness, improper temperature, or unsuitable prey size.
If your gecko stops eating:
- Check enclosure temperature; cold environments reduce appetite.
- Offer live prey that stimulates hunting instincts.
- Avoid handling before feeding; stress can suppress appetite.
- If refusal persists beyond a week, consult a reptile vet for health evaluation.
Ensuring a proper diet combined with optimal living conditions keeps your gecko active and thriving.

Frequently Asked Questions
What to feed a house gecko for a balanced diet?
House geckos thrive on live insects such as crickets, mealworms, and fruit flies. These provide essential proteins and fats needed for growth and energy. Supplementing their diet with calcium powder is important to support bone health and prevent metabolic bone disease.
How often should I feed a house gecko live insects?
Feeding frequency depends on the gecko’s age. Juveniles require daily feeding to support rapid growth, while adults can be fed every other day. Always offer appropriately sized insects and dust them with calcium to ensure proper nutrition.
Can I feed fruits or vegetables to my house gecko?
No, house geckos are insectivores and cannot digest plant matter effectively. Feeding fruits or vegetables is not recommended as it can cause digestive issues. Their diet should focus solely on live insects supplemented with vitamins and minerals.
What supplements are necessary when feeding a house gecko?
