The farm's second harvest

Wait. Mealworms make fertiliser?

They do. And the story begins at a real Queensland insect farm.

Mealworms eat, grow and shed their outer skins. The dry material they leave behind is called frass. We put that overlooked by-product to work as plant food.

A little strange? Sure. Useful? That's the idea.

A closer look

Three things you might not expect.

There's more to this ingredient than a funny name.

A little biology

What do prawns have to do with mealworms?

Both have outer structures containing chitin. Researchers are studying how insect-derived residues interact with soil biology. Interesting science, not a promise of pest protection.

An honest look inside

A fertiliser with receipts.

Nitrogen, phosphorus and potassium aren't just buzzwords. We've independently analysed our frass and share the measured results. Natural batches can vary.

The unexpected part

Does it pong?

Not like you might expect. Rich Roots is dry and earthy, with relatively low odour compared with some manure products. Natural batches can vary.

Quick answers

What is mealworm frass?

The dry material mealworms leave behind as they feed: droppings and shed exoskeletons. Rich Roots contains 100% raw mealworm frass, with nothing synthetic added. More about the ingredient →

Is it just for pots?

Use it in veggie beds, garden soil and lawns too. The right amount depends on what you’re growing and your soil. Find your amount in our Grow Notes →

Which pouch should I choose?

Both contain the same ingredient, 100% all-natural mealworm frass. The 110 g Starter Pouch is a way to try frass yourself, or a perfect gift for a friend who loves plants. The 360 g Garden Pouch gives you more for regular feeding. Multi-pouch options and subscriptions are available for both. Compare the pouches →

Where we grow matters.

Rich Roots acknowledges the Traditional Custodians of the lands on which we work in Slacks Creek and Woodhill. We recognise the Yuggera and Yugambeh language-speaking peoples of the Logan region, and the Mununjali people of the Woodhill area.


We honour their continuing connection to Country, culture and community, and pay our respects to Elders past and present, and to all Aboriginal and Torres Strait Islander peoples.


The creek that gives Slacks Creek its name was originally known as Mungaree, meaning “place of fishes”. This local name reminds us of the enduring connections between land, water and life in the places where we work.
