The goal is to cover the insect entirely in the powder. Then, when the gecko eats the insect, it will also be ingesting the supplement. You can dust the insects every two to three feedings.

If you find that your gecko is ignoring insects that you place in its cage, you may be feeding it too often or too much. Try spacing feedings further apart, by a day or so, and see if your gecko is more interested in its meals.

If you are feeding mealworms, you should place them in a food bowl. This will allow the gecko to easily access them.

If you do not place the mealworms in a dish, they will simply burrow under the tank bedding and the gecko may not be able to find them. Crickets should be placed as close as possible to the gecko.

This water should not be very deep, so that there is little chance of the gecko drowning in it.

This will be a gradual adjustment to find the perfect diet for your gecko. Don’t make sudden, extreme changes. Just decrease the amount you are feeding your gecko a little at a time. This can be done most easily by decreasing the number of insects you give to your gecko but keeping the number of feedings the same.

Geckos can also eat mealworms and superworms. However, these aren’t the best feeders so they shouldn’t be used as a staple diet. Waxworms should only be used as treats as they are very fatty and addictive. Crickets and Dubia roaches provide better nutrition. Other options are hornworms for treats and silkworms and Phoenix worms (a. k. a Black Soldier fly larva or calci-worms) for variety. Variety is very important in a leopard gecko’ diet. Different insects give your gecko different nutrition. This is why it is a good idea to vary the insects you are feeding your gecko. [9] X Research source

Just to be sure, however, feel free to call the pet store before you go to make sure that the insects you want are in stock. Don’t just try to collect bugs outside. Feeding your gecko random bugs will not give it the nutrition that it needs. Another problem with bugs from outside is that they may contain parasites, which you definitely don’t want to feed your gecko. Additionally, buying bugs at a pet store will guarantee that you have enough to keep your gecko well fed.

If you want to buy crickets in bulk and keep them alive, you will need to give them food and water. [10] X Research source In fact, crickets need to be gut-loaded before they are fed to your gecko. Many crickets bought at a pet store are practically starving. This means feeding them a high-quality food, so that they pass on that nutrition to the gecko when they get eaten. Mealworms, on the other hand, can simply be kept in the refrigerator in a substrate material, such as wheat bran.

Depending on how many and what kind of insects you bought, you will need different types of containers. For example, crickets need to be kept in a container with a lid to keep the crickets inside. Mealworms, on the other hand, can be kept in the refrigerator and only need a lid to keep the smell in.

Get a calcium supplement and a multivitamin supplement. The calcium supplement should include calcium and vitamin D3, which helps the gecko absorb the calcium. Dust insects in calcium every other feeding, and multivitamins every three feedings. Be sure to not use D3 if using UVB and do not leave D3 in the tank. Repashy Calcium Plus and ReptiVite are two all in ones that include both calcium and multivitamins. If you use one you won’t need any other supplements. Not giving supplementation can have very adverse effects on your gecko. It will cause metabolic bone disease. [11] X Research source Do not mix the calcium and multivitamin supplement together, this is very unhealthy for your gecko.
