Worm Composting Questions

Composting with worms, also called vermicomposting, is a popular way for those with even the smallest apartments to make their own natural fertilizer from their food scraps. Get answers to some of the most common questions about composting with worms.

Will the worm composting setup smell bad?

As with any composting system, if it is done correctly, it will not smell bad. In a vermicomposting setup, microbes quickly break down the food scraps and the worms feed on the microbes. Ensuring that your food scraps are small is the best way to encourage their quick breakdown.

Can I have a worm composter in my house?

Because the compost system won't smell (see above), it's easy to have a worm composter in your house. Popular locations are basements and porches but many people keep them handy under the kitchen sink.

Will the worms escape?

Worm composters, whether purchased commercially or homemade, have a vented lid that allows air circulation without allowing the worms to escape. Also, worms naturally avoid light and they prefer to remain in the humid darkness of the composter where they have an unlimited supply of food.

What can I feed the worms?

The microbes that worms eat can break down almost any food substance. However, adding meat or any other animal product to your worm composter is not recommended as they take longer to break down and could create a smell. Common additions are vegetable and fruit scraps, tea bags and spent coffee grounds.
