The Product

What is BioMeal Flourish Mealworm Frass?

The ultimate 100% natural soil enhancer & plant immunity booster.

Mealworm frass is the waste and shed exoskeletons of our mealworms - the natural, nutritious byproduct of the mealworms that we grow here on Australia's largest livefood insect farm. Because our insects are raised without chemicals or pesticides, our frass is 100% pure, organic and completely safe for your soil, family and pets.

Is Mealworm Frass Fertiliser safe around children/animals, and edible plants?
Is Mealworm Frass Fertiliser safe around children/animals, and edible plants?
How does Mealworm Frass Fertiliser compare to other fertilisers like manure or blood & bone?
Unlike some other animal-based fertilisers, mealworm frass is virtually odourless, doesn’t need composting, and won’t burn plant roots.
What’s the benefit of mealworm frass over worm frass?
Unlike mealworms, worms have no exoskeleton, which means their frass lacks the chitin that is so powerful in promoting plant pest-immunity and resistance.
How does mealworm frass boost plant immunity?
The mealworm exoskeletons contained in the frass effectively “trick” your plants into thinking they’re being attacked by insects. The chitin in the exoskeletons trigger a hormonal response in your plants to defend themselves. This means that if pests, parasites and diseases come along to feed on your plants, those plants will have their defences ready.
Where does all your mealworm frass come from?
Right here, on Australia’s largest insect farm! Our family has been raising and supplying feeder insects like mealworms for animal owners around the country for over 35 years. Mealworm frass is a totally natural zero-waste byproduct of mealworm farming that we’re able to sustainably recycle into nutritious plant fertiliser.
How much does shipping cost?
Orders valued at $150 or over qualify for free shipping. Orders under that are a flat rate of $16.
