What are Fungus Gnats?
The dark winged fungus gnats are more of a nuisance but in large numbers can attack healthy plants. They feed on fungi and decaying material. If you see them, you need to check your potting media and make sure it is still ok. The adults are small flies with dark brown bodies. The young, or maggots, are whitish with black heads. Avoiding over watering and removing rotting material will usually control these insects.
