Giant Mealworms (Cupped)

We do not carry giant mealworms. They are present on the website for informational purposes. Giant mealworms are regular mealworms (Tenebrio molitor beetle larvae) that have been treated with S-Methoprene, a hormone that acts as an insect growth regulator. This hormone prevents larvae from turning into beetles, which makes them grow bigger than usual. 

S-Methoprene is not known to cause illness in reptiles and amphibians, but it may affect pet invertebrates such as tarantulas and scorpions.

Our Giant Mealworms are each ~1.5" extended, which is good for feeding adult leopard geckos, bearded dragons, ackie monitors, and more giant tarantulas and scorpions. If you need a worm bigger than our Large Mealworms but smaller than Superworms, the giant mealworm is perfect for you!

Our pre-cupped option is a convenient alternative to "boxed" or "bagged" feeders. Plus, if you're pet stores or a reseller, our mealworm cups offer a professional pre-packaged solution.

How often should giant mealworms be offered?

Giant mealworms can be used as a regular part of your pet's diet, preferably as part of a rotation with at least two other types of "staple" feeder insects.

Giant mealworms should always be lightly dusted with calcium powder prior to feeding.

How to care for giant mealworms:

Mealworms should be kept chilled in a wine cooler or the top shelf of a refrigerator door between 42 and 50 degrees. They will become dormant and stay fresh for up to 30 days.
