The Mosquito Control Kit-Economy is geared specifically for eradication of mosquitoes but the liquid concentrate in the kit, Talstar P is labeled for fungus gnats. Bonide Systemic Granules can be used indoors to help control the larvae of the fungus gnat. Be sure to read and follow the product label for best results. Fungus gnats are usually found in plants that have been overwatered, so allowing containerized plant soils to dry will be the key to eliminating this pest.
