Give your garden wildlife a naturally nutritious treat with Chubby Dried Black Soldier Fly Larvae (Hermetia illucens), more commonly known as Calci Worms, Calciworms, Calcium Worms, BSFL or Soldier Fly Larvae.

Black Soldier Fly Larvae for Wild Birds

Dried Calci Worms are a convenient high-protein wild bird food that can be offered throughout the year. Their naturally high calcium content makes them a useful addition to a varied feeding routine, particularly during demanding periods such as breeding, nesting and fledgling season.

They can also be offered during moulting and through colder autumn and winter weather when garden birds can benefit from access to energy-rich supplementary foods.

Calciworms for Hedgehogs

Our dried black soldier fly larvae can also be offered to garden hedgehogs as an occasional treat. Feed a small quantity alongside a suitable, nutritionally balanced hedgehog food rather than using dried insects as their main diet.

Always provide a shallow dish of fresh water nearby. Never offer milk to hedgehogs.

How to Feed Dried Calci Worms

Chubby Calci Worms can be fed straight from the bag. Simply add a small amount to your usual wildlife feeding area.

Suitable for:

• Mealworm and insect feeders
• Wild bird seed feeders where suitable
• Bird tables
• Ground feeding trays
• Hanging feeding dishes
• Hedgehog feeding stations

What Are Calciworms?

Calciworms are the larvae of the Black Soldier Fly (Hermetia illucens). You may also see them described as black soldier fly larvae, BSFL, soldier fly larvae, calcium worms, calci worms, calciworms or dried insect grubs.

They are naturally rich in calcium and have a more favourable calcium-to-phosphorus (Ca:P) ratio than many commonly fed dried insect treats. This makes black soldier fly larvae a popular choice for people looking to add a calcium-rich dried insect food to a varied wild bird or wildlife feeding routine.
