  • Are BSFL good feeder insects?

    Yes! They're one of the best feeders for insectivorous and omnivorous exotic pets. They are low maintenance, quiet, and wiggly in a way that is very appetizing to many reptiles and amphibians. Best of all, they are incredibly nutritious. For best results, use as part of a rotation with other nut...
  • Can I feed black soldier flies to my pet?

    Black soldier flies are edible and quite nutritious, and can be used as an entertaining, unique treat for your pet. Chameleons in particular seem to enjoy the flies. Keep in mind that black soldier flies only live for about 5-8 days.
  • Do BSFL bite?

    Not at all. They are just soft little grubs, and can't harm you or your pet in any way.
  • Do BSFL need to be dusted?

    Nope! Black soldier fly larvae are one of the few feeder insects that have a naturally balanced calcium-to-phosphorus ratio. So they can go straight from the cup into your pet's food bowl.
  • Do BSFL need to be gut-loaded?

    Nope!
  • How do I store BSFL?

    Your black soldier fly larvae will arrive in a small plastic cup, buried in substrate. Simply keep them in this container at room temperature, or better yet, in a wine cooler or beverage chiller. You can also keep them in the fridge, but try and make sure it is the fridge door and not the coldest...
  • How long do BSFL last?

    If kept properly cool, a cup of BSFL will last a couple of weeks. If kept at room temperature, they will start to pupate before then — black soldier fly larvae that are preparing to turn into flies will turn dark, so it's best to feed those ones off first.

  • What do I feed my NutriGrubs/soldier fly larvae?

    You don't need to feed them, they come self-contained in their plastic tub with the substrate that they need, feeding them can increase humidity in the tub and cause the grubs to defecate in their substrate. This will lead to them growing more quickly and becoming flies in less time than usual an...
  • What is the substrate that is used in the cups for my Nutrigrubs?

    Nutrigrubs come in their self-contained habitat cups, the substrate used is a corn/rice blend which is easily shaken off the grubs using a sifter or a colander and easily saved to add back to the cups. If your reptile does end up ingesting a small amount of the substrate it is perfectly safe.
  • Will my BSFL turn into flies?

    They can, if kept at room temperature for too long. Keeping them cool will delay this process. To not end up with flies, however, it's best to only order as many black soldier fly larvae as you can feed off within two weeks.
