Use Yellow Sticky Cards to Control Fungus Gnats

Yellow sticky cards are an easy method for catching and killing many flying pests, such as fungus gnats and whiteflies. The fungus gnats you will catch are the nuisance adults, but the larvae do all the damage by feeding on roots.

If you do not want to use organic or synthetic pesticides on your indoor plants, sticky cards are a good alternative.
