Can crested geckos eat June bugs or not? It’s known that insects and larvae are part of the crested gecko’s diet.

However, does that mean crested geckos can eat all insects? No, some insects are dangerous and can cause illness or death when eaten by geckos.

Here’s what you need to know about feeding crested geckos June bugs.

Can Crested Geckos Eat June Bugs?

Yes, crested geckos can eat June bugs. However, we don’t recommend catching or gathering June bugs to feed to your crestie.

Instead, we recommend mealworms, crickets, dubia roaches, and superworms. These insects and larvae provide much better nutritional value than June bugs and are readily available in a lot of stores.

Are June Bugs Toxic To Crested Geckos?

No, June bugs aren’t toxic to crested geckos. June bugs don’t contain dangerous chemicals or toxins that can be harmful to your crested gecko when ingested.

Instead, their hard exoskeleton increases the chances of your crested gecko suffering from impaction. Aside from that, June bugs are relatively safe to eat.

3 Reasons Why You Shouldn’t Feed June Bugs To Crested Geckos

Although June bugs are insects that are part of a crested gecko’s diet. June bugs are not the best insects to be fed to crested geckos. Here’s why.

Difficult to get in large quantities

Getting large quantities of June bugs to feed your crested gecko is difficult. You need a good amount of June bugs for your crested gecko to reap the nutritional benefits.

However, large quantities are not readily available in pet shops like dubia roaches or calci worms. You have to go outside to catch these bugs.

This can be quite difficult to do and time-consuming since you can’t get several June bugs at once place.

Might have pesticides

Although June bugs don’t contain toxins. They have might have pesticides that can cause illness or death in your crested gecko when eaten.

Most June bugs are not available in pet shops. So if you decide to feed June bugs to your crested gecko. You will have to feed wild June bugs from your garden or environment.

Hard exoskeleton might cause impaction

Impaction is a health condition that affects geckos when they ingest hard, loose, or big food/substate/insects/larvae.

A gecko suffering from impaction will find it difficult to defecate. If not treated, your crested gecko will suffer from loss of appetite, increased weight gain, and lethargy.

June bugs have hard exoskeletons that crested geckos find difficult to digest. Your crested gecko might suffer from impaction if consumed regularly.

Best Alternatives To June Bugs

Dubia Roaches

Dubia Roaches
Dubia roaches

Dubia roaches are the best feeder insects for crested geckos. They are popular, easily obtained, and packed with nutrients.

Dubia roaches can be fed live, dead, or blended into a puree/paste. We recommend gut loading or dusting before being fed to your crestie.

Dubia roaches don’t contain harmful toxins or chemicals that might cause illness or death. Hence they aren’t only safe but also nutritious.

Calci Worms

Calci worms

Calci worms are the best source of calcium and should be in every crested gecko’s diet. Also known as the black soldier fly larvae or phoenix worms.

By feeding calci worms to your crested gecko you prevent it from developing metabolic bone disease. Once a crested gecko develops metabolic bone disease and it’s not treated.

It will become fatal and kill your pet crested gecko. To prevent such a thing from happening. Calcium should be regularly included in the diet. A large amount can be obtained from calci worms.



Crickets are the second most popular feeder insects given to crested geckos. They are rich in proteins, fats, and carbohydrates which help promote healthy growth in a crested gecko.

Crickets can be fed live, dead, canned, dried, or blended into a puree. If feeding crickets live, we recommend dusting with powdered supplements to boost their nutritional value.

Also, not so many crickets should be fed at once. Too many crickets will attack and bite your crested geckos. 3-5 crickets are the recommended amount in a feeding.  



Waxworms or the larvae of the wax moth are nutritious larvae that can be fed to crested geckos. Waxworms are rich in protein, fats, and carbohydrates.

They are excellent feed for baby and juvenile crested geckos because of the large number of proteins. Waxworms don’t contain toxins that could be harmful to your crested gecko.

They are readily available and can be fed live, dead, or blended into a paste.



Hornworms are one of the few larvae in the wild that can be fed to captive crested geckos.

Hornworms should be served as a treat because you can’t get large quantities available and the decreased possibility of encountering them in the wild.


Crested geckos can eat June bugs but we don’t recommend feeding them to your crested gecko.

June bugs are not readily available in large quantities, and might have pesticides or cause impaction in your gecko. Hence, they are not great food for your crested geckos.
