Giant (Golden) Mealworms

from $5.00

Giant (Golden) Mealworms or hormonally altered- Tenebrio molitor are specially-reared mealworms grown to a larger size, making them thicker and more substantial than standard mealworms while still being smaller and easier to digest than superworms. They offer a perfect middle-ground feeder option with moderate protein content. They are easier to store and maintain than live superworms, though they still require gut-loading and calcium supplementation due to their calcium-to-phosphorus ratio. 

We particularly recommend giant mealworms for mid-sized bearded dragons, adult leopard geckos, chameleons, and medium-sized tarantulas, as they provide more nutrition per feeding than standard mealworms without the more rigid exoskeleton and higher impaction risk of superworms. They're excellent for adding dietary variety and encouraging feeding in animals that find standard mealworms too small but aren't ready for the size and hardness of superworms, making them ideal for transitioning juveniles to adult-sized feeders.

What's the ideal gutloading diet for Giant (Golden) Mealworms?

We highly recommend feeding this species a balanced diet of vegetables & proteins. Additionally, we suggest adding cuttlebone or crushed eggshells to the enclosure to boost calcium intake. For vegetables, we recommend bok choy, mustard greens, and collard greens, as well as organic butternut squash or any other squash that is readily available. Cucumbers can be given for water only; note that they mold easily, and springtails must be added to the enclosure to keep mold spores to a minimum. 

How can I breed and keep Giant (Golden) Mealworms?

We highly recommend keeping this species on Royal Soil, with Cork Round or Cork Flats, with additional springtails such as Folsomia candida to ensure mold doesn't build up in the container. We recommend a minimum enclosure size of 6 inches cubed for Mealworms, or you can use our Fossorial Fissure Medium enclosures to store upwards of 1,000 of them. For larger Feeders such as Superworms, we recommend a minimum enclosure size of the Terrestrial Terrain Large. For all roach feeders, such as Dubia Roaches or Red Runners, we recommend a 27-gallon tote with air holes drilled.
