Weed and Insect Management
The fungus gnat has recently been recognized as an important pest in greenhouses. Although greenhouse plants are commonly attacked, house plants may also become infested. Several genera in the family Sciaridae are of economic concern, such as Sciara, Orfelia, Lycoriella and Bradysia species.
