Calci worms contain 20 to 40 times more calcium than Dried Mealworms which contributes to stronger bones and eggs.

Calci Worms (also known as Calcium Worms) are the larvae of the Black Soldier Fly (Hermetia illucens). They are high in protein, energy giving fat, amino acids and incredibly high in calcium.

These dried insects have a positive Calcium to Phosphorous ratio which research has proven promotes increased animal health and contributes to stronger bones and eggs for wild birds. These properties also make them an excellent addition to the diet of growing vertebrates such as hedgehogs and chickens.

Calci worms are a versatile and easy way to feed the wildlife in your garden ideal for use with feeders, bird tables and ground feeding

For the birds already visiting you, Calci Worms can simply be added to your regular feeding station. However, to attract new birds we recommend placing a second feeder near where you’ve seen them perch. This gets them used to taking their insects from you.

Please ensure that a good source of water is provided if feeding Calci worms to ensure that the garden birds and Hedgehogs are kept hydrated and healthy. Alternatively, soak the worms overnight before feeding.

All orders over £25 (or weighing 12.5kg or more) are delivered free of charge.

For out of areas (e.g. Northern Ireland, Scottish Highlands and Islands, Isle of Man and outlying areas), please refer to our delivery information for our delivery charges.

  • Every time we order from Garden Wildlife Direct, we are never disappointed. Shipping is always as expected, the couriers they use are fantastic and the product is also fantastic (well the birds seem to love it, not tried it myself).
