How To Rid Vermicompost Bin Of Mites
Now, let’s talk about how to correct moisture problems and remove mites from your bin. There are a few different ways you can solve this problem. The first method is adding an item like a watermelon rind to the top of the bin. Leave the skin for about an hour to attract mites to the hull. After an hour, return to the bin and remove the mite-covered shell. This step will help cut the population down quickly.
Next, you are going to want to address the moisture problem. If you haven’t already made holes for leachate drainage – you should now. You can shift the worms around to drill a few holes in the bottom. Put a boot tray or cookie sheet underneath your bin to catch any excess liquid.
If you can’t drill new holes in your bin, you can add dry bedding to absorb excess moisture. You can add dry bedding to the top of the container and let the moisture wick up. Other people find that mixing in dry bedding doesn’t disturb their worms and solves the problem.
In the future, if you have watermelon rinds or other items to feed to your worms, freeze and thaw before feeding. This freezing and thawing method will break the cell walls and help excess moisture drain before adding it to your worm bin. Be sure to add plenty of dry bedding at every feeding to prevent mites from taking over your bin.
Overall, it is prevalent to see mites in your worm bin. They are helpful decomposers that are part of a healthy worm ecosystem. However, it’s time to take action when their population grows proportionally. First, remove as many mites as you can. Then drain excess liquid if possible. If not- add plenty of dry bedding to wick all excess moisture.
