I'm really struggling with a huge infestation of fungus gnats and it's seriously affecting my plants—and my sanity! I'm currently bottom watering and have predatory plants in a dish of water, but there are just so many of them. I've also tried using mosquito bit tea. Does anyone have suggestions for what else I can do to tackle this problem?

Sticky traps everywhere! Also, make sure to use mosquito bits directly in the water tray of your plants. The BT in the bits needs consistent exposure to the gnats to work properly, so keep that in mind when applying!
Definitely use sticky traps around your plants. They're super easy to set up and catch those little pests quickly. You should also consider adding some soil nematodes; they're great for getting rid of fungus gnats. Just sprinkle them in and let them do their thing!
You might want to try Bonide Systemic granules. I was having a hard time with gnats and used this on the soil of the plants that were giving me trouble. Just apply it once a year or when you repot, and you should be good. I haven't had any gnat issues for almost three years since I started using it!
Just a heads up—it's a chemical treatment, so if you have kids or pets, you might want to be cautious!

Where can I find nematodes? Could I use them indoors?
