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)/¯
If you want solution that actually works:

1/4 tsp per gallon of water. Water with it once or twice. Done for a long time, they won’t come back.

I’m not a fan of pesticides on my food, but for ornamentals indoors I see no issue with is.
Oooh is it true that its pretty toxic for pets?
Try neem cake on top of the soil, it stinks, but it's pet friendly. It saved my drama ficus twice. Also, you might be overwatering
Haha, is it a really strong stink?
Looks interesting. Also seems to have nutrients as well. Will look into this. Thank you!
it's not a deal breaker and after a few days it should go away, also depends on how much you use. I also used to mix it with soil, it might reduce the smell but I don't bother lately since I don't use too much. And it's for sure better than spraying neem oil around lol
Thanks. Will keep this in mind going forward :)
Systemic granules. These are the solution, hands down. I’ve tried absolutely everything and this is the only solution that genuinely works. Neem oil did nothing. Mosquito bits kinda work, but they only kill the larvae and you have to keep re-applying it. Systemic granules will solve the problem
Seems to really do the trick, but potentially toxic to pets?
Yeah, if you choose to use it, keep it away from kids and pets.
