OK, the other answers are fine however, the only reason there are knats is due to overwatering. Many parameters contribute to overwater such as lighting, temp., etc. Using too much too often is the main reason. B4 you water make sure the soil is dry. Check the bottom of the plant if you have access to the overflow tray.



The root rot attracts them and fascilitates the reproductive cycle and nutrients(decay). Once the watering is under control the knats typically go away a couple of days afterward! Check the plant doctor online...
Reply:Lightly spray the plant with water mixed with a few drops of dishsoap.
Reply:changing the soil just might be a good idea.. take the plant and place it in the tub and mix 1 or 2 drops of dish soap in water sprayer.. and spray the leaves.. or use a damp cloth 2 remove meldew or fungus.. once you spray the leaves, do not put in sunny window, till leaves dry.. and it sounds like the plant is around dampness.. so maybe a place near the sun would be better.. gnats will take forever 2 kill.. call and ask at a hardware store if they carry sticky fly paper.. this is your best bet 2 get rid of the bugs.. bummer eh
Reply:First off.... get some good plant spray and spray the plant everyday!!!!. Next,,,,,, change the soil. They love to breed in the soil!!!!! That should take care of the problem.
