Do Crested Geckos Need to Eat Live Insects? Surprised!

Crested Geckos are considered extremely low-maintenance pets and tend to be the perfect starter pets for first-time reptile owners.

While feeding live vs. feeding powdered food can be a controversial topic amongst reptile experts around the world, there are many benefits and considerations before finalizing your decision on which direction you want to go. 

A Crested Gecko does not need live insects to live long and healthy lives. However, there are some significant benefits to feeding them live insects that may sway an undecided mind. 

In this article, you will find out why feeding live insects could be beneficial, what live insects they can eat (and the approximate costs associated), how often to feed said insects, and what food to provide if you decide not to feed live.

Pros and Cons of Feeding Live Insects

The Pros and Cons of Feeding Live Insects

As stated above, cresties do not need live insects to survive. Thanks to the modernized pet food industry, there are plenty of options for people who would rather not willingly bring live insects into their homes. 

Powdered meal replacements allow crested geckos to get most of the nutrients they need to live a long, healthy life.

However, there are some benefits to feeding live that could sway you over to the live insect side of the debate. 

One of these benefits is that it gives the gecko more animal protein than they would get via a powdered meal replacement.

Typically, Whey Protein Isolate is used in these powdered replacements. 

While it does the job, it is just a supplement for what they would get in their natural habitat.

It has been shown that crested geckos that are not offered insect options do not grow nearly as well as ones that are. 

While crested geckos are not known for their hunting ability, and can be quite clumsy hunters, feeding live insects stimulates that part of their brain.

It recreates how they would eat in the wild, where their diet consists of more than 50% live insects.    

When Live Feeding Becomes a Necessity

Live feeding is highly recommended if your crested gecko is not growing as quickly as they need to or seems to be getting bored with its regular diet. 

If you notice the food you give is being eaten less and less, or not at all, that is a big sign you need to switch the menu up for your gecko.

This can be difficult to tell at times, especially with younger geckos, because they usually only need a few licks of powdered meal replacement before they are full. 

How to Know if Your Crestie is Not Growing Properly

Most breeders estimate that a baby crested gecko can take one to two years to become an adult. Even though the average age to reach adulthood is 18 months, that is not always the case.

There are a couple of different aspects to look at when trying to distinguish between a gecko growing appropriately or not growing quite fast enough.

Those factors can range from humidity and heat fluctuations in their tanks (72-75 degrees Fahrenheit and 60-80% humidity is ideal) to how long they were incubated to if they are eating enough. 

A baby crested gecko is considered a juvenile until they hit 16 grams, which on average takes no more than 18 months- 2 years of age. They are around 35-55 grams for females and 25 grams for males once they are fully mature adults.

If your gecko is not achieving these growth milestones, it may be necessary to introduce live feedings. 

How Often You Should Feed Your Crested Gecko Live Insects

The answer to this will vary based on how old your gecko is. Juveniles will need to be fed every day, whereas fully grown adults will only need to be fed live two to three times a week. 

When fed live, the insect must be smaller than the space between your gecko’s eyes (too big, and it could lead to impaction) and must be gut loaded and dusted before feeding to your gecko.

All “gut loaded” means is that the insects were fed a nutritious diet to ensure your pet reaps all the benefits of a well-rounded meal. 

They can be bought like this if you decide to buy in small quantities, but they will need to be maintained while you’re keeping them alive.

With meal replacement powders, it is recommended to feed every other day, and this is to ensure the food doesn’t dry out or go bad.

What kinds of insects should crested geckos be fed?

Insects that a Crested Gecko can eat can be narrowed down into two categories: staples and treats. 

5 Staples in your Crested Gecko’s Diet

Dubia Roaches: Price ranges between $4.50 and $12 depending on the size of Dubia Roach and the quantity you buy. These can be purchased online and delivered live.

Black Soldier Fly Larvae: Price ranges between $5 and $16 depending on size and quantity. It can also be bought online.

Crickets: Prices range between $5 and $12 depending on size and quantity. It can be bought online or can usually be purchased locally in a pet store.

Super Worms: Prices range between $7-$26. These can be bought in larger quantities, making the price range a bit wider. These can also be purchased online.

Silkworms: Prices range between $7 and $25 depending on quantity.

4 Treats That Can be Fed Occasionally

Hornworms: Average cost was around $10 for four worms.

Wax Worms: Average cost is around $10 for 250 worms.

Butter Worms: Cost ranges between $7.50-$15 depending on quantity.

Mealworms: Cost ranges between $6.50-$10 for 250 worms.

A few things to keep in mind before you commit to live feeding are as follows: 

  • You will need to maintain the life of these insects, gut load them, and dust them before feeding them to your gecko. 
  • The mineral or vitamin supplement needed for dusting can cost around $10-$15, depending on which brand you go with. 
  • You will also need to have a separate container to feed your gecko live food to ensure that the insect doesn’t die and rot in your terrarium (which can cause your pet to get quite sick if ingested). 
  • This also keeps your gecko from getting too stressed out if they can’t catch all insects from previous feedings.
  • Feeding in separate, more confined containers also helps ensure your gecko can actually catch the insects you’re giving them since they are not known to be the most agile of predators, as mentioned above.

So, what can crested geckos eat besides insects?

There are several well-known, and respected brands of MRP (Meal Replacement Powder) diets out there.

Arcadia has an all-natural Crested Gecko blend that contains the full spectrum of minerals, vitamins, fruits, and insect protein. 

Pangea and Repashy are also well-known brands of meal replacement powders that have different flavors to keep your gecko from getting bored of its food. These can be easily found online or in your local pet store. 

There are many different flavors you can pick from if you do decide to go this route, and there really isn’t one that will be better than the others.

Whatever flavor you choose would all depend on what your gecko prefers, so feel free to mix it up to see what they like! 

You can also get Jelly Pots, but this would be a very last resort as they are mostly fruit with a sprinkling of Vitamin A and C.

There really is not enough nutritional benefit to these meal substitutes to be very advantageous to your gecko. 

On occasion, you can try to feed them fresh fruit, such as mango, banana, strawberry, watermelon, or even sweet baby foods but don’t be alarmed if they don’t take to it. 

Much like people, geckos seem to acquire likes and dislikes of different flavors and foods, so again, feel free to experiment from time to time to see what your gecko enjoys the most.
