Can Carnivorous Plants Control Fungus Gnats Indoors?

Question: Botanist suggested a carnivorous plant for occasional kitchen gnat infestations. Will it work? Can it survive if it eats all bugs? Which plant?

Answer: They catch bugs but rarely enough for control. Helpful for small outbreaks, but don't expect eradication. Good sticky-leaf options for gnats: Drosera adelae, D. capensis, D. binata, Pinguicula moranensis. All tropical, happy as houseplants. Key: They're plants first—need light (sunny window) more than bugs. Place for light, not just near compost.

Good Growing!
