How to Make a Worm Compost

Overview

Gardeners and those with leftover food scraps can combine these scraps with worms in order to create a compost that will provide excellent nutrients for plants. Once set up and stacked on top of each other, two compost bins can be used to create a worm compost that is easy to maintain. However, compost bins have a tendency to attract fruit flies. Fortunately, there is a cheap and humane method of trapping and releasing the fruit flies.

Step 1

Puncture several holes into both bins so that you can drain the compost bin. Put these holes on the bottom and sides of the compost bin. Use a drill with a 1/16-inch bit for this.

Step 2

Soak two newspapers in water in order to make them moist. Place the moist newspaper into both compost bins.

Step 3

Fill your hand with dirt and toss the dirt into both compost bins. Worms need dirt in order to digest their food.

Step 4

Place a piece of wet cardboard on the ground overnight. In the morning, red worms should be attached to the cardboard. If they're not, red worms can be purchased from a variety of vendors.

Step 5

Measure the cardboard and then cut it so that it will fit into one of the compost bins. Moisten the cardboard with water before putting it into one of the compost bins.

Step 6

Take the lid of the bottom compost bin that you just placed your cardboard in and flip it upside down. Place the lidless compost bin with the cardboard on top of the flipped-over lid. This lid will serve as a place to collect fluids that have dripped out of the compost bins.

Step 7

Stack the lidded bin on top of the lidless bin. The cardboard that you placed in the lidless bin will support this lidded bin.

Step 8

Put vegetable scraps throughout the compost bin. The worms will seek out food. Add red worms and increase the amount of scraps in the compost bin every day as the number of red worms multiplies.

Getting Rid of Compost Fruit Flies

Step 1

Drill holes in a plastic container.

Step 2

Place banana peels in the container.

Step 3

Leave the container in the kitchen overnight.

Step 4

Check to see if the container is filled with fruit flies.

Step 5

Take the fruit flies outside and release them.

Tips and Warnings

  • Placing too many scraps in a compost bin can cause the bin to emit a foul odor. However, smaller amounts of food scraps will not smell since the worms will be able to successfully digest them. Avoid adding citrus foods, since they can make the compost bin too acidic for worms.
