How to Keep Compost Worms Warm & Healthy

Just because they are chewing on your garbage doesn't mean compost worms don't like to be warm and safe from the cold, so keep them healthy and snug with these tips.


  • Step 1: Move compost bin to warm area Move your compost bin to a warm area such as your garage, a storage shed, or in a smaller container under your kitchen sink when winter's wind gushes in.
  • Step 2: Set bin in the ground Set the bin in a hole in the ground with the same circumference as the bin and about half as deep if you have nowhere to move your bin. Cover the bin with straw or dead leaves.
  • TIP: Keep the bin in the sunniest area on your property for optimal heat.
  • Step 3: Add more nitrogen Add more nitrogen, also known as green waste. When it decomposes, the green waste produces heat, but adding too much can increase the acidic levels and leave you with fried worms -- keep your nitrogen balanced with the carbon by adding hardwood ashes or charcoal ashes.
  • Step 4: Insulate Insulate your compost bin with newspapers, straw, vegetable scraps, wood chips, or egg cartons to keep the worms shielded from the frigid weather.
  • Step 5: Attend to compost in winter Do not neglect your compost pile in the winter. This is the biggest cause of dead worms and a useless spring compost. Even though it's difficult to trudge out into the yard in the cold, keeping the compost pile active in the winter is a must.
  • FACT: Worm composting is also known as vermicomposting and utilizes red worms. Earthworms are not used because they cannot withstand living inside of an indoor bin. Red worms are thought to be able to process as much waste each day as their own weight.
