Need advice on getting rid of fungus gnats
I have fungus gnats in every single one of my poor plants!! I desperately want to get rid of them. What's the most effective way to get rid of them permanently?
The fastest way to get rid of gnats is going to be to figure out what it is that is attracting them and get rid of it. With flying insects, it's always about step one: identify what's attracting them.
When it comes to black fungus gnats, they are generally attracted to areas of organic matter that are oversaturated with water and what that usually is is that it's someone who's overwatering their plants and has damp soil. That could also be if your yard has poor drainage and ends up collecting a lot of water if your soil feels oversaturated. But generally, areas of large moisture buildup are what are going to be the gnat attractant, and solving that will help get rid of the gnats. For me personally, if I have potted plants and I suddenly notice a gnat issue, I'll let my plants dry out and maybe even scoop off the top inch of soil and I'll find that the gnat population will drop or completely disappear after a couple of weeks. If you are trying for a very quick reduction of gnats, then most likely you want to use actual chemicals labeled for gnats and you want to combine that most likely with a kind of UV light trap.

I know that damp soil can lead to gnat infestations, so I've been bottom watering my plants because it doesn't leave the topsoil wet. I just place my potted plants in a dish with water so it soaks up through the drainage holes.
While it seems to be working so far, there are still a few bugs flying around. Am I making a mistake, or are there any other causes for fungus gnats I should know about?

When getting rid of flies, a common mistake people make is not identifying the kind of fly they're targeting. If you're targeting fungus gnats, you should know that they come from overwatered plants, so you'll want to reduce having overwatered plants in your home as much as possible. Some bait you can use in a trap for fungus gnats is raw potato chunks.
Bonide Systemic Houseplant Insect Control is what helped me get rid of my fungus gnat infestation. All you have to do is sprinkle a little on the soil of each of your plants and water it for it to start working. Just keep in mind that plants that are naturally pet-friendly will become more toxic when treated with Bonide Systemic, so if you have kids or pets that like to eat your plants, you should be careful about using this.
Ohh now I'm wondering if I've been watering my plants a little too often, oops. It's been hot this summer so I've probably been going a little overboard and maybe I should back off.... But I'll try the potato trick and see how it goes in the meantime. Fingers crossed
