How the Grubhouse works

Four steps. One complete habitat.

01
Drop in scraps

Drop in scraps

Open the lid hatch. Coffee grounds, fruit peels, leftover veg, whatever you'd compost.

02
Larvae do the work

Larvae do the work

Larvae eat up to 2× their weight daily at peak feeding. Breathable walls keep air moving so the bin stays healthy instead of going anaerobic.

03
They self-harvest

They self-harvest

Mature larvae climb the ramps or the walls. The Grub Track catches both and drops them into the tub below.

04
Feed your animals

Feed your animals

Toss to chickens, reptiles, fish, birds. Pure protein, totally free.
