I would just swap out the soil with some new sterilized soil like super soil and rinse the roots off completly they are a bitch to get rid of if you have a bad infestation. Then I would still treat them with the gnatrol or something similar every 5 days for 2 weeks.
u.g.u Reviewed by u.g.u on . GNATS !!!!!!!! SOMEONE HELP!!!! :D My plants have developed gnats. I am trying to find out how to get rid of them, I hope I can get some opinions. I also wanted to know how or why I got them in the first place. Do they occur because of standing water? I've read that it's the larvae that cause the problems. If someone could help me, I would be truly thankful:dance: :dance: Rating: 5
