*Now packed in our new and improved proprietary substrate. Buy one of our sifters to separate the grubs from the GrubSoil™ easily.

Our Small NutriGrubs (Black Soldier Fly Larvae) are less than half the size of our Medium CalciGrubs. They are a great staple food item for many small species of reptiles, hatchling reptiles, amphibians, inverts, fish, birds, etc. They can be stored at room temperature or they can be cooled down for a longer shelf-life. Wine coolers, regular coolers, or under a air vent work great. Most fridges are colder than the recommended 55F and could kill them.

Pro tip: If you notice some of your grubs turning black, they are close to the "fly" stage. Keep them until they turn into a fly and watch your pet go after them! It's excellent enrichment for your pet, and they are a slow-moving fly, so they are easy to catch. Plus, if your pet doesn't like the grubs, it should like the flies!

Great food for:

  • Bearded Dragons
  • Chameleons
  • Lizards
  • Geckos
  • Chickens
  • Birds
  • Fish

NOTE: Our black soldier fly larvae are fed an extremely high-quality, plant-based diet to deliver optimal nutrition for your pet. However, this does mean that they tend to grow and pupate faster than black soldier fly larvae from other breeders. For best results with our black soldier fly larvae, make sure to keep them cool (~55°F) and only buy one month's supply at a time. 


Commonly known as Phoenix Worms®, CalciWorms®, and ReptiWorms™, all are the same species of Black Soldier Fly Larvae known as Hermetia illucens.

Awesome company

Love these, geckos love them too, only wish it was easier to separate from the substrate even with the sifter

Perfect worms

Love these things, my lizards go nuts for them and when they morph into flies my frogs and geckos have the best time chasing them down. Unlike dubias these guys don't play dead and seem to struggle to burrow and unlike mealworms they turn into tasty flies and not bitter beetles. Small NutriGrubs™ Review
