Gardman 500g Calciworms

Gardman Calciworms are a premium, protein-rich bird food designed to provide your garden birds with the essential nutrients they need for strength, health, and vitality. Packed with calcium for strong bones and healthy feathers, these dried insects are a natural, energy-boosting treat loved by robins and other wild birds — perfect for year-round feeding, especially during breeding season or the colder months.

Key Features

  • High in protein and calcium for strong bones, glossy feathers, and healthy egg production

  • Loved by robins, but suitable for a wide range of garden birds

  • Ideal all-season supplement, supporting birds during breeding or cold weather

  • Versatile feeding options – use in suet and mealworm feeders, on bird tables, or ground feeders

  • Convenient 500g pack for easy storage and regular feeding

Product Description

Give your feathered friends a nutritious boost with Gardman Calciworms 500g, a natural and highly digestible food source that helps maintain birds’ overall health. Calciworms are the larvae of the black soldier fly, making them a sustainable alternative to mealworms with even higher calcium levels. This mineral is vital for egg-laying birds, aiding in shell formation and bone strength, while the high protein content supports feather condition and energy levels.

Specially loved by robins, blue tits, great tits, and long-tailed tits, these dried insects can be easily mixed with suet pellets or seed blends, or offered alone for an irresistible treat. Whether you’re attracting birds to your garden in winter or helping them thrive during breeding season, Gardman Calciworms deliver dependable nutrition in every feed.
