Happier, healthier wild birds, boosted by black soldier fly biology.
Enriched with insect protein derived from Black Soldier Fly, Mouche Boule™ is a high-energy suet ball created to support wild birds through every season, providing reliable, energy-rich nutrition when they need it most.
Wild birds thrive on insects, yet conventional suet treats rely almost entirely on standard tallow and cereal fillers. Mouche Boule™ changes the game by blending oats, beef tallow and Black Soldier Fly protein to create a nourishing suet ball with more protein and fat than conventional recipes.

Feed the wild. Complete the circle.
Responsibly made in Lincolnshire from transformed surplus food waste, Mouche Boule™ delivers a naturally balanced ratio of crude protein and digestible fats to fuel wild birds when energy demands are at their highest. Net-free, 100% made in Britain, fully traceable and fully accountable, it is designed for the wild and made to complete the circle.
The owner-operator of the UK’s largest operational commercial-scale insect Biotechnology Business, FKS, was built to turn local surplus food and farm waste into valuable, low-emissions products. We do this through bioconversion: using the Black Soldier Fly (Hermetia illucens) to convert organic waste into useful co-products, like Mouche Boule. In plain terms, we take unnecessary waste and transform it into ingredients that support a more resilient food system for the UK.
