Me and my partner love having plants indoors but we get infested with gnats. We've tried hydrogen peroxide, and the yellow insect stickies and drying the soil out but nothing seems to work.
Any tips?
A few things have helped. The yellow stickies have done a lot to slow them down. I’ve also put about an inch of perlite (or vermiculite) on top of the soil as I’ve heard they can’t lay eggs in it. As a last resort I’ve take a few pots outside and totally replaced the soil when nothing else worked.
Once they’ve set in, I’m not sure there’s any winning. All you can do is beat them back.
Do you think the perlite has helped? Thought about doing this to all our pots.
I think it helped a bit. Really though, the yellow stickies did the most as long as I kept replacing them as they filled up. I also put many many of these around the plants.
For some reason, I'm finding that quite a lot of them aren't ending up on the stickies. Maybe there's a trick to placing them just right? ¯\(ツ)/¯
