Giant Mealworms (Cupped)

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.
