If you've noticed tiny, dark insects flying around your houseplants, you likely have fungus gnats. These tiny flies can be a nuisance indoors and may also damage your plants.
Fungus gnats lay their eggs in moist soil and their larvae feed on plant roots and decaying organic matter. Because of this, the key to managing fungus gnats is to let the soil dry out in between watering and don't overwater plants. Water plants from the bottom using saucers under pots.

Any room in the home can attract and harbor indoor pests including kitchens, pantries, bathrooms, closets, storage areas, or other living spaces.
