Just like their diet in the wild, pet geckos survive mainly on insects that they can hunt. Geckos should be fed crickets as the main staple of their diet. You can supplement the cricket diet with meal and wax worms to ensure a balanced meal. You should also regularly give your gecko vitamin and mineral supplements that you can pick up at any local pet store. Crickets, meal and wax worms can also be found at local pet shops and bait stores.
Follow these simply instructions for feeding geckos:
1. Purchase crickets for your gecko that are no bigger than the size of their head. This will ensure that the gecko can properly catch and eat the crickets. About a day before feeding the crickets to your gecko, you will want to feed the crickets to give them some nutritional value. Feed the crickets either fish flakes, dried fruits and vegetables or dried dog or cat food. This process is often called “gut loading” the crickets. You can also dust the crickets with a calcium supplement before a feeding by placing the calcium powder in a bag with some geckos and shaking the bag gently until the crickets are fully coated.
2. After feeding the crickets, wait about 12-24 hours before feeding them to the gecko. Geckos should be fed twice a day when they are young. Decrease feeding time to once a day around 5-7 months. By 7 months, the adult gecko should only need to be fed twice a week.
3. Only give the gecko as many crickets as they can comfortably eat within 15-20 minutes. The amount of crickets given will largely depend on the age and size of the gecko. Start by only giving your gecko two crickets to test out how quickly it eats, and increase the amount if necessary.
4. Once a week, feed your gecko mealworms or wax worms in a shallow bowl. Two to three worms will be enough to satisfy your gecko for the week. Wax worms are high in fat content, so should be used as more of a treat than a part of the gecko’s diet. It’s advised that you snip the heads off the mealworms or wax worms to make them easier to consume. Also be sure that the worms are placed in a smooth container with sides high enough that the worms cannot escape. Dust the mealworms or wax worms with nutritional supplements if you think your gecko need additional vitamins and minerals on top of what is received through the crickets.
5. Closely monitor how much your gecko eats and reduce the number of crickets, mealworms and wax worms that you feed your gecko if you notice that he or she is filling out.
6. Just like with any other living animal, you should provide fresh water for your gecko daily. The water dish should be shallow enough that if an insect happens to get in the dish, it can escape quickly without being caught in the dish and drowning. Clean the dish often to prevent bacteria and fungus from growing in the water bowl.
