Black Solider Fly Larvae (Hermetia Illucens) | Small

Crazy Critters offers you the convenience of high-quality live feeder insects delivered to your door!

Our live BSFL are available in 2 different sizes: 

Black Solider Fly Larve (BSFL) naturally have a balanced calcium:phosphorus ratio; making them an ideal staple in your pet's diet.

Feeding a calcium-rich feeder insect, like BSFL, can minimise the risk of nutritional diseases related to low calcium intake or inversed calcium to phosphorus ratios, common in captive diets.  

Crazy Critters live black soldier fly larvae (BSFL) are perfect for animals stimulated to feed by movement.

You can feed our insects to your pet:

  • frogs
  • geckos
  • insect-eating birds
  • lizards
  • predatory fish
  • scorpions and spiders
  • turtles; and
  • wildlife

to provide variety in their diet.

Note: BSFL are known by a range of other names, including: 

  • Calciworms
  • Nutriworms;
  • Reptiworms;
  • Vitaworms; and
  • Phoenix Worms


We recommend that you: 

  • unpack your BSFL on arrival to reduce the risk of losses

  • store them at room temperature in a storage container with a ventilated lid (fly screen insert or drilled holes)

  • apply a 5cm - 10cm strip of Fluon Insect Barrier Paint to the top inside edges of your storage container to prevent escapees! 

  • raise them on a high-protein diet like Crazy Critters Gutload - Premium Insect Food and provide fresh produce every second or third day


We offer live shipping rates in the checkout to ensure our customers are offered accurate shipping charges that reflect order volume.

We send out orders on Monday, Tuesday and Wednesday each week to ensure your live insects arrive before the weekend. This practice helps reduce any losses in transit.

Our live insects are carefully packed with dry food, fresh food or a combination of both, to ensure they get sufficient nutrients and moisture in transit and arrive in excellent condition.

All Crazy Critters boxes have adequate ventilation for airflow and are labelled to ensure appropriate handling. We also slightly oversupply our live insects (up to 20%) to account for any small losses, so you can be confident you receive the right numbers in your order, every time

We understand the most important part of ordering live food is that they arrive... Alive! So Crazy Critters offers a 100% Live Guarantee. If your live insects arrive in poor condition, let us know and we'll make it right.


Although BSFL have an extremely high calcium content, like many other common feeder insects, they are deficient in fat-soluble vitamins A, D3 and E. For this reason, when BSFL is a staple in your pet's diet, we recommend using multivitamin supplements each week.

It is also important to note that the digestibility of the nutrients offered by BSFL significantly increases when chewed vs being swallowed whole. 

If your pet swallows their food whole, note whether or not BSFL is being passed intact in faeces. This indicates your pet was unable to digest the BSFL, diminishing the intake of available nutrients.

You can overcome this issue by puncturing the BSFL exoskeleton (i.e. crushing or mashing) before offering your pet, allowing calcium and other nutrients to be better absorbed.
