Our Products
Two products from one insect. Whole dried larvae for birds and fish, and the frass left behind for soil. Both supplied from 300g packs to full pallets and bulk containers.
Natural Insect Nutrition For Birds & Fish
Brook & Hollow comprises 100% high-protein, high-calcium dried black soldier fly larvae, providing an ideal natural supplement for wild birds and woodland species within conservation areas. The larvae are carefully dehydrated to preserve their original shape and size, successfully encouraging natural open-environment foraging behaviour. The balanced nutritional composition supports strong body mass, optimal feather development, skeletal strength, and successful wild breeding cycles.
For professional estates, land managers, gamekeepers and conservation trusts focused on biodiversity projects, Brook & Hollow provides the invertebrate protein these species evolved to hunt. It is highly effective at holding birds on managed ground, because a bird returns to where the searching was worthwhile, and occupying birds through the weeks when they are most likely to move.
Brook & Hollow larvae are reared solely on pre-consumer, vegetable-based substrates to ensure they are rich in essential amino acids and healthy fatty acids. It is naturally high in antimicrobial lauric acid to support robust gut health and overall flock resilience.
For the home garden and pond, Brook & Hollow offers a natural way to nourish diverse local wildlife. These larvae are rich in functional fats to help wild birds through demanding breeding cycles and post-moult recovery, ensuring that your local ecosystem receives the essential nutrients needed to thrive.
