Eliminating Fungus Gnats and Other Flying Pests

Identifying and Treating Soil-Dwelling Insects

Sudden appearance of tiny gnats around houseplants.

Routine hygiene: Mist and sponge leaves frequently (except hairy-leaved plants, cacti, succulents) to keep foliage clean and detect pests early.
Identify: Could be whiteflies, aphids, fungus gnats, or thrips. Catch a specimen for ID.
Treat: Spray with malathion or, better, a systemic insecticide (absorbed into sap). Isolate infested plants, preferably outdoors during treatment.
Aftercare: Resume regular misting to maintain humid, dust-free conditions that deter reinfestation.

Early detection and systemic treatment break the cycle effectively.
