Build A Bin
The possibilities are endless when it comes to building your own bin. The only things you really need for your worms to thrive are coverage, drainage and aeration. Below are two very popular methods for building your own home worm bin.
Plastic bins are one of the easiest ways to go, all you need to do is drill holes in the bottom for drainage. If the bin is going to be outside with no other rain protection, you’ll need to use a lid. If using a lid, you also need holes near the top for aeration. If you’re not using a lid because your bin will be indoors or covered by some other means, you don’t need a cover. You’ll just want to make sure to use extra bedding or straw to cover the food scraps so unwanted pests don’t get in.
Drainage holes. We recommend 1/4″ holes every 3-4 inches.
Aeration holes. These holes can be a little bit smaller (1/16″.)
Another very simple option is to make a bin out of wood. A wooden bin can be anything from a basic box with a piece of plywood as a lid to a box that doubles as a coffee table!
