Problems and solutions

Main problems with a vermicomposter

Smell of putrefaction There is too much food. Decrease food intake.
Ammonia smell There is too much nitrogen-rich material. (green and fresh materials) Balance the system by adding carbon-rich materials. (newsprint, dead sheets, shredded cardboard)
Smell of sulfur (rotten egg) The litter is waterlogged and there is a lack of air at the bottom of the vermicomposter. Add dry shredded newspaper or cardboard. Open the lid and turn down the feed for a while.
Worms come out of the vermicomposter The litter is too wet or too acidic. Add newspaper or cardboard as before, for acidity, add dried and powdered eggshells or a little wood ash.
Fruit fly Food exposed to the open air attracts flies and allows them to lay their eggs. Always cover the waste with a layer of litter. The use of beneficial nematodes and/or a little diatomaceous earth is also highly recommended.
Ant The inside of the vermicomposter is too dry. Coat the legs of the vermicomposter with Petroleum jelly and moisten the tanks
