Dealing With Mites in Earthworm Bins
Mites are tiny invertebrates with eight leg-like appendages, naturally found in composted manure and organic material. Mites are especially attracted to moist, acidic environments. They are a common inhabitant of worm bins and beds and vermicomposting systems. Most mites are not harmful to your earthworms but problems commonly occur when mite population increases to high levels.
