    I like to put a rock type dressing over the soil of my indoor plants, that seems to help a good deal. If the gnats can't reach the soil, they can't lay eggs, so after a season or two you'll be rid of them. Also honey + dishsoap + vinegar makes a lovely trap for the live buggers

      How much like an inch of rock layer ?

      Yes, even a 1/2 inch layer if it's small gravel or lecha. Just so bugs can't reach the soil from landing

      Keep in mind, adding this layer will also change how often you need to water because it'll keep the moister from evaporating a little. Think of putting a lid on a pan. Definitely feel the soil down under the top layer every time to check if your plant needs watering

    i saw a video that if the infestation is pretty bad you can do 1 part of 3% hydrogen peroxide and 4 parts water and just spray alllll over i haven’t tried it personally but hope this helps!! :)

    What level of “not expensive” are we talking? I have had awesome success with “death drops” from an online plant shop but won’t name them so I don’t get in trouble with the rules. I double the “rocks” but I use small leca balls - there are some that come in different colors and are adorable. Just need to put at least 1/2 to 3/4 inch deep or they won’t help.

      The fungus gnat death drops are $38 and have lasted me 2 going on 3 seasons (2yrs) and I have 50+ house plants. I put the drops in every watering as soon as I see a single gnat. And then intermittently when I have no gnats.

    Not sure if cinnamon will kill but it helps prevent so it’s a cool organic and cheap option for preventative especially if you have other plants on the area.

    I recently used Nematodes in the soil and it knocked them all out! It took over a week to see a difference which makes sense since they are going after the eggs, not the parents. Good luck!
