Fungus Gnats



This term applies to a very large group of insects some of which damage the roots of plants. Usually they are just a nuisance as they hover around over-ripe fruit in a fruit bowl. They are often mistaken for fruit fly. Adult fungal gnats are attracted to damp conditions and decomposing organic matter.

Fungus gnats are also members of the fly family, usually about 1 millimeter in size. They can be recognized by their all-black, rather "skinny" bodies, compared to that of fruit flies. 


Fungus gnats are attracted to moisture and fungus, and are therefore attracted to compost bins and can sometimes be observed crawling on the bedding in a worm or compost bin.

The soil in which houseplants are potted can also provide an environment in which fungus gnats can flourish.  If they are present in your houseplants, this indicates that there is too much moisture in the potting mix. Try letting the plants dry out completely before the next watering. This will kill the larval stages in the soil.
