4Avoiding problems

Worm farms are fun to maintain and shouldn't become smelly or attract pests. If a problem does arise you might want to try one of these solutions.


  • Chop up or blend food scraps, so they are easier for worms to eat.
  • Worm bedding should smell earthy like soil. If it starts to smell rotten, mix in a source of dry organic materials such as newspaper or dry leaves to balance the moisture, nitrogen and carbon. You can even sprinkle in some dolomite lime to balance the pH.
  • The worst case for any scenario is simple: empty the worm farm and start again with some new worms.
  • Compact worm farms generally service a small household (1-2 people) – if you have more scraps than your farm can handle, try adding a compost or bokashi bin, or upgrade to a larger worm farm.
  • It's best to avoid food waste in the first place by planning your weekly meals in advance - visit the Food Lovers Republic to learn more.

Worm farms aren't just home to worms. You'll see lots of other tiny creatures that are part of a healthy ecosystem, including spring tails, earwigs, mites and billions of microorganisms like bacteria you can't see.
