Gnats on Houseplants

Nov. 29, 2010

This year I started many new plants outdoors in the fall, wanting to save some annuals as houseplants. Shortly thereafter, when I brought them inside, I had an infestation! Gnats on houseplants are disgusting, so I searched to find out how to exterminate them. I read about fungus gnats, that love creeping around in the soil of over watered houseplants. So I purchased a fungicide with insecticide. No go. Populations were growing. Then I tried a general insecticidal soap. Nothing. Sand on top of the soil, and a bowl of vinegar to trap the little buggers. Didnt even slow them down. When I read a female gnat can lay 300 eggs alone, it was time to find a solution!!!

How Do I Get Rid of Gnats in Houseplants?

Thanks to the gardenweb forum my gnat population is almost extinct. I hauled every pot down to the kitchen sink, ran the water until it was hot as possible and gave each plant a good soaking through. I found gnats of course, a centipede, a lady bug and a box elder. Since theyre not all completely gone and breed faster than bunnies,  let the houseplants dry out and soak them one more time.

WARNING! Be VERY CAREFUL which plants you soak in scalding water. Some  very tender or newly established plants (like potato vine) didnt make it through this method.
