What is a Swell Live Calci Worms Pre-Pack?

A Swell Live Calci Worms Pre-Pack is a bundle of live Calci worms that have been specially bred for reptiles and other exotic animals. Calci worms are new to British reptile keeping but are already extremely popular in America - going under different names, such as Soldier grubs. As this name suggests, they are in fact the larvae of the Black soldier fly (Hermetia illucens).

The worms are calcium-rich feeder insects that are a great meal for growing reptiles, such as a baby Bearded dragon, or unwell reptiles that need more fat and calcium. You can also gut load Calci worms with extra nutrients, which is particularly useful for staple diet Calci worms.

How long do Calci worms live?

We send our Calci worms via a quick delivery service to ensure you get a couple of weeks before they change into Black soldier flies. This process can be slightly slowed by keeping your worms in a cold enclosure. It is worth bearing this in mind when you order our bulk Calci worms as some may change before they are all served.

What does a Calci worm turn into?

Calci worms naturally change into Black soldier flies after a few weeks. However, flies can also be a good food source for certain animals. frogs and geckos are known to particularly enjoy the challenge of fast-flying prey. While Black soldier flies in nature can carry disease, this is not the case in captive-bred specimens which can be safely fed to your pet.
