When it comes to worm bins there are really not many demands that need to be fulfilled to make the worms happy in their new home.
You can find out more about those easy to solve issues in the articles of the "Beginners guide to worm composting" that you can find in the top navigation bar of this website.
Below you see a few examples of worm bins we had in our home and backyard for many years.
When it comes to worm bins there are many options open to you. A simple diy worm composting bin can be made of wood, plastic, bricks or even concrete blocks. Most domestic worm bins are made from plastic containers. They are usually easy to get hold of and quite durable. Another benefit they offer is the fact that unlike metal they don't heat up which helps to prevent an overheating of the worm bedding and food. If you are an experienced worm composter and you don't need to produce worm tea / worm leachate you might just use any plastic bucket or container with a lid and a volume of at least 5 gallons / 20 liter to get your worm composting process started. Just add some bedding and a batch of worms and you are ready to go. However the problem with these kind of worm bins is that they usually don't have any ventilation holes and that in case of over watering or unexpected flooding the worm herd could drown. Another problem could be overheating on a very hot summers day.

Once you got all in place
Drill the ventilation holes near the top of the "working bin" using the same drill bit.
Put the working tray aside for now and use the hole saw bit to drill the hole for the tap as low as possible into the side of the bottom / worm tea collecting bin. "Make sure you leave enough space at the bottom for the nut of the tap.
Push or screw the tap through the hole. Then place the washer over the thread of the tap and tighten it with the nut.
Place the "working bin into the "collecting bin" and cover with the lid and you are ready to go. Once you got your worm bedding and worms place them into the working bin of your "DIY worm composting bin and begin to recycle your kitchen-, garden- and or dog waste.
A worm bin of this size is usually ok for one or two people. But if you have more waste either build another worm bin or use bigger containers still following the same principles.
