Most homes in Kitsap County can subscribe to curbside compost pickup. Yard waste, food scraps (including meat and dairy), paper towels, and napkins go into the provided cart. This waste is composted at North Mason Fiber in Belfair, WA. Learn how to subscribe.

Backyard composting is best for yard and garden wastes like grass, leaves, and chipped wood. You can also put most food scraps in a backyard compost pile. There are many methods of backyard composting, including composting in heaps or in a container.

Worm composting is best for kitchen scraps like fruit and vegetable peelings. Red wiggler worms create castings, a valuable plant “health food.” You can make a worm bin from inexpensive materials or purchase a pre-made worm bin kit. Worm composting can be done indoors.

Supplies Needed:

  • Composting worms. Buy composting worms online or locally at Bay Hay & Feed (call ahead for availability).

  • A wide and shallow container. 10-gallon plastic "shatter proof" storage totes with a solid color work well. Drill holes in the bottom and sides for drainage and airflow.

  • Bedding. Shredded newspaper, shredded office paper, brown leaves, or straw.

Set Up:


Feeding Tips:

  • Worm bins can handle around one pound (or one quart) of food scraps per week per square foot of bin surface area. This means a bin with a floor measuring 1 foot by 2 feet will take about 2 pounds (2 quarts) of food per week.

  • Freeze your food scraps to prevent fruit flies and speed up composting. Keep a container in your freezer and add food scraps throughout the week. Then, thaw the scraps and feed them to your worms. Freezing makes the food softer, allowing the worms to eat much faster.

  • Bury the food scraps under shredded paper to prevent fruit flies.
