Calcium is a key nutrient for reptiles, they need it to survive - but getting enough in their diet can be a struggle.

Luckily Calci Worms are here to help.

Why choose Calci Worms?

Calci Worms, which are the larvae of Black Soldier Flies, are naturally much richer in calcium than other feeder insects. Importantly though they are unique in their balanced calcium and phosphorus ratio - which makes them not only nutritious but also completely safe and ideal as a staple diet. 

Increasing the amount of calcium in a reptile's diet has a number of benefits:

  • Increases bone strength

  • Increases tooth strength

  • Promotes heart health

  • Helps to prevent Metabolic Bone Disease

Hatchlings fed on Calci Worms have shown to be 30% larger than their clutch mates in a matter of weeks. Breeders have also noted more vibrant colouring and higher activity levels.


Calci Worms also work like any other live feed, providing protein and fat needed for healthy growth. As they are a live feed they also have the benefit of providing your pet with the mental stimulation that comes from tapping into their natural hunting instincts.

In addition to this 53% of the fat in Calci Worms is beneficial lauric acid. Lauric acid is an excellent antimicrobial, especially against coccidiosis - a sometimes fatal infection.


How to use Calci Worms

Calci Worms are ready to serve straight from their pot and due to being packed in a nutrient bedding they need no extra feed. They are naturally packed with calcium and nutrients, so gut loading, extra feedings, and special vitamins are not required. They can be used safely as a staple feed.

  • Calci worms do not require refrigeration and can tolerate high temperatures. They produce no noise or odour. They cannot climb or jump so there is no risk of escape.

  • They wiggle like crazy which excites reptile, amphibians, arachnids, and fish - they are a great feed for picky eaters.



Our Calci Worms are grown sustainably on waste fruit and vegetables that would otherwise be headed to a landfill. In this way, we are actively helping fight climate change and food waste, making a product that is low carbon and environmentally friendly.
