Questions & Answers

I feed my young box turtles mealworms for treats. Is this suitable for gut loading worms that will be fed to turtles?

Answer by ChewyAug 03, 2021
This recipe is intended to be fed to insects only. It is not formulated to be fed to worms.

Would this work for trying to keep some rescued ladybugs alive in a terrarium?

Answer by ChewyNov 10, 2021
This diet is not intended for use in breeding or raising insects. The use of Better Bug® Gut Loading Diet will enhance the total body nutrients of the feeder insect, resulting in optimized nutrition being delivered to your reptile. This food is best for insectivorous reptiles such as Anoles, Basilisks, Bearded Dragons, Chameleons, Geckos and Water Dragons.

Is this a powder that goes on top of what you are already feeding your crickets (collard greens) or is this a replacement for the greens?

Answer by ChewyJun 30, 2025
This product is designed to be the sole diet for your feeder insects—like crickets—for 24 to 72 hours before offering them to your reptile. If you’re also providing other foods like collard greens during that time, the insects may choose those instead, which can reduce the effectiveness of the Better Bug diet. To get the full benefit, we recommend placing the Better Bug feed in small containers within the insect enclosure, along with a source of fresh water (either freestanding or in a sponge), and removing all other food items during that period.

does this diet replace the need to dust the insects in calcium prior to feeding them to your gecko?

Answer by ChewyNov 10, 2021
No additional supplementation of insects is needed when giving this food. This cricket diet contains high levels of calcium, omega-3 fatty acids and vitamin A to enrich the diets of insect-eating reptiles, birds and mammals as part of a complete insectivore diet. This recipe has a calcium content of 9.00% maximum.

This is NOT a good staple food for your insect colony but it is an amazing gut loading diet to give right before feeding the insects to your reptiles. It smells strongly of fish oil and my cats did tear open the bag because of it so be careful of that if you have curious free roaming mammal pets lol

My cat wants it so bad I had to start keeping my whole leopard gecko supply tray in the closet, so be warned if you have a cat. She picked up the bag and tried to run away with it. The mealworms seem to like it too and the leopard gecko likes the mealworms. Recommended by a vet

Mazuri food

I read about this food and thought it would be great. Got it super fast, but it killed all of our crickets and dubias. Would not recommend this product.
