Why Won’t My Crested Gecko Eat Crickets?


It doesn’t necessarily mean there’s something wrong with him.

First of all, Not all geckos like crickets!

While crickets are a common feeder insect for crested geckos, some individuals simply prefer other options like dubia roaches, mealworms, or waxworms.

Your crested gecko may not eat crickets for various reasons: preference for crested gecko diet (CGD), stress, improper cricket size, incorrect enclosure conditions, health issues, or simply disinterest.pen_spark

Try offering different feeder insects and see if your gecko shows more interest.

Look at the size!

Ensure the crickets are the right size for your gecko.

Juveniles need smaller crickets, while adults can handle larger ones.

Offer freshly gut-loaded crickets, meaning they’ve been fed nutritious food that benefits your gecko.

Do these:

  1. Monitor your gecko: Observe their behavior and check for any signs of illness.
  2. Check the enclosure: Ensure all parameters are within the recommended range.
  3. Offer CGD: See if your gecko prefers it over crickets.
  4. Try different feeders: Offer other insects like dubia roaches or calcium-dusted mealworms.
  5. Gut-load your feeders: Ensure your crickets receive proper nutrition.

Remember, patience is key.

Don’t force your gecko to eat if they are not interested.

It may take some time to figure out what your gecko prefers and adjust its environment to optimize its health and appetite.

Thanks, but Is it normal for my crested gecko to refuse crickets?

Yes, it’s perfectly normal for crested geckos to show little interest in live insects.

This is because commercially available crested gecko diet (CGD) is formulated to provide them with all the essential nutrients they need to thrive, including protein, vitamins, and minerals.

In the wild, crested geckos consume a varied diet of insects, fruits, and nectar.

CGD mimics this balanced diet, and many crested geckos find it highly palatable and convenient.

While some crested geckos may still enjoy the occasional cricket as enrichment, others simply don’t see the need for them once they’ve been introduced to CGD.


Q: What size crickets should I feed my crested gecko?

As a general rule, crickets offered to your crested gecko should be no larger than the width between the gecko’s eyes.

This ensures the cricket is an appropriate size for your gecko to both capture and consume safely.

Crickets that are too large can be intimidating to your gecko and pose a choking hazard.

If you’re unsure about the appropriate size, it’s always better to err on the side of caution and offer a smaller cricket.

You can also break down larger crickets into smaller pieces before offering them to your gecko.

Q: Can I feed my crested gecko other insects besides crickets?

Absolutely! Variety is beneficial.

You can try dubia roaches, mealworms, or waxworms, ensuring they are appropriately sized and gut-loaded.
