The Magic of Insect Frass: Nature’s Most Powerful Organic Fertiliser
Looking for a natural way to supercharge your soil and grow healthier plants? Meet insect frass—an organic fertiliser made from the castings (droppings) of black soldier fly (BSF) larvae. Don’t let the humble origins fool you—this stuff is garden gold.
Frass is packed with:
Slow-release nitrogen for long-term growth
Bioavailable calcium and magnesium for stronger roots
Chitin, a natural compound that strengthens plant immune systems
Unlike synthetic fertilisers that can burn plants or degrade soil over time, frass works in harmony with nature. It improves microbial activity, enhances soil structure, and promotes resilient, vigorous growth—perfect for flowers, vegetables, herbs, and potted plants alike.
Our Root & Rise – Demeter’s Dust pellets are made from 100% BSF frass and nothing else. No additives. No composting time required. Just sprinkle around roots or mix into compost for instant benefits.
Why switch to frass?
It’s safe for pets and kids
It won’t pollute waterways
It feeds the soil as well as the plant
Plus, it’s made from a circular system: BSF larvae are fed on food waste, and their frass returns nutrients to the earth—closing the loop in the most elegant, eco-conscious way.
Whether you’re an urban gardener or backyard grower, frass is your secret weapon for a thriving, low-maintenance garden. Give your soil what it really wants: natural, insect-powered nutrition from Root & Rise.
