How to Kill Fungus Gnats on Strawberries

Fungus gnats are persistent insects that are drawn to moisture on and around various plants. Unlike some other gnats, fungus gnats leave a discharge on plants and fruits. This discharge can turn to mold and eventually kill the plant. Plants that grow fruits such as strawberries are also susceptible to these annoying insects. The mold growth can ruin your strawberries. Left untreated the gnats will multiply and spread to other plants and fruits.

    • 3

      Spray any bugs you see on the plant or on the strawberry packaging.

      Remove any plant leaves or strawberries with signs of fungus on them.

      Take any strawberries or strawberry plants that are contaminated with fungus and separate them from the other fruits and plants. Place them in plastic bags and seal the bags tightly before disposing of them. This will help reduce the risk of the fungus spreading.
