How to gain rid of gnats who took residence within my houseplant? I bought this little spider plant at a church sale something...

I bought this little spider plant at a church sale something like 10 years ago and somehow it has survived despite my occasional negligence when I be younger.

I recently discovered gnats living surrounded by the soil, so I threw out the soil, put the plant in a pitcher of water for a week outside. I get new potting soil, re-planted and two weeks latter I found gnats in the soil again.

Is in attendance any solution to this? I know they have preen that kill weeds and doesn't spoil plants, but is there a similar product for getting rid of bugs?

I honestly love this plant so any proposal would be welcome.

Thanks!

Answers:    The bugs are fungus gnats. They are near because the soil is too wet and the roots may be germ to rot. Set the plant in the sink and remove the drain tray to drain as much hose down as possible. Then do not water the plant till the soil feel very dry. Just drying out the soil will grasp rid of the gnats if you can be patient. If not put some rubbing alcohol within a spray bottle and spray the surface of the soil with it. You will murder any fungus gnats that it hits on contact. But that is merely a temporary fix. Keep your plant dryer and they will dance away. Two hours after you water your plants dump the hose out of the drain tray so the plants are not sitting in hose and they are less predictable to be over watered. More plants are killed by too much hose down than by too little! Good luck.
