compost worms

Our compost worms, Eisenia fetida and Dendrobena veneta, are native to Switzerland and Europe. Local partnerships ensure short transport routes.

The difference between the earthworm and the compost worm

Both the compost worm and the earthworm (dew worm or common earthworm) belong to the earthworm family, but differ in their habitat and function. Earthworms that live in the soil contribute to soil aeration by digging tunnels and feed on organic soil matter. Compost worms, on the other hand, favour rich organic materials such as compost heaps. They are more effective at breaking down kitchen and garden waste, live in denser populations and are ideal for worm composting systems as they quickly produce nutrient-rich compost.

Finding compost worms

Compost worms are often found in rich, organic environments such as compost and manure heaps, especially where kitchen and garden waste is present. They are often found in dung heaps, hence the name 'dung worms'. Friends who already use worm composters are also a good source of compost worms. To get your worm composting off to an effective start, we also offer the option of ordering a starter population of compost worms.

Frequently asked questions about compost worms

What is the difference between an earthworm and a compost worm?

Compost worms and earthworms, both part of the earthworm family, differ in their habitat and function. Earthworms promote soil aeration and feed on organic matter in the soil. Compost worms, on the other hand, prefer rich organic materials such as compost heaps, are more effective at breaking down kitchen and garden waste and are ideal for vermicomposting systems, where they quickly produce nutrient-rich compost.

How do I get compost worms?

Compost worms thrive in organic environments such as compost and manure heaps, especially where kitchen and garden waste is processed. Known as 'manure worms' in dung heaps, they can also be sourced from existing worm composters. Alternatively, we offer to order a starter population for effective worm composting.

What do compost worms like most?

Compost worms like to feed on kitchen waste such as fruit and vegetable scraps, coffee grounds and eggshells. Meat, fish and dairy products should be avoided as they cause putrefaction. Citrus fruits and onions should be used in small quantities due to their acidity. A varied, plant-based diet is best for them.

How long do compost worms survive?

Under ideal conditions, compost worms can live for up to five years. Their lifespan depends heavily on the environmental conditions, such as the quality of the compost, temperature and moisture. A balanced diet, avoiding extreme temperatures and maintaining a suitable level of moisture in the compost heap are important for a long and fulfilling worm life.
