Dried Calci-Worms (Black Solider Fly Larvae) 1kg - for feeding wild birds, hedgehogs and other wildlife.

  • Calci-Worms are the larvae of the Black Soldier Fly (Hermetia illucens) - a naturally nutrient rich feeder insect that's high in protein, energy giving fat, amino acids and uniquely high in essential calcium
  • Suitable to feed to a wide variety of garden birds, poultry, insects, fish and mammals including hedgehogs
  • Typically have up to 40 - 50 times the amount of calcium than other dried insects or worms
  • They have a positive calcium to phosphorus ratio meaning they aid the development of strong bones and eggs
  • Also known as Calcium Worms, Nutri Grubs, Sunworms and Soldier Grubs

Natural sources of calcium are becoming increasingly harder find for garden birds, hedgehogs and wildlife due to the ever growing use of pesticides in agriculture and the reduction of wild land. Offering Calci-Worms as part of a balanced diet alongside other types of food gives our wildlife access to a wider range of vital nutrients that they often struggle to find themselves.

Green stickered Items are delivered to most parts of the UK at the price shown.

Red stickered items are priced to be shipped in a box along with a green stickered item so each box must contain at least one green stickered item to allow you to check-out.

Please note we can only ship up to 29kg per box (28kg to France) so for example, if you purchase a 20kg green stickered item there is space left in the box for 9kg of *Add-on* items. This is a way for you to save money when buying smaller items and still have them delivered the next working day!

If you wish to buy just a selection of our *Add-on* items we have a shipping box which enables you to do so. Click here to view or add this to your basket.
