Highly recommend beneficial nemotodes to treat, and mosquito dunks to maintain - both should be available on Amazon!

Mosquito Bits work. It’s the granular form of Mosquito Dunks. Instructions are on the package. Use it every time you water.

If even soaking it for half an hour in a mix of peroxide and water doesn’t work, it might be time to repot it completely, reducing it to its roots, soaking the roots for 30 minutes in a mixture of 2 parts water, 1 part hydrogen peroxide, then rinsing it with water, and gently drying it with a paper towel before repotting in completely new, dry soil. You might wanna try bottom watering your plants to prevent attracting the gnats again. Hope this helps!

dry the plants out a lot, like water once a week max. but possibly even wait 2 weeks the first time to water them.

then don’t spritz them with water anymore if you are

isolate them from each other

repot the worst ones using new soil

Mosquito bits in the soil and the bug lights work well for catching the adults

I have had major gnat infestations and here’s what’s worked for me:  
Definitely buy the sticky traps to trap the adults  
Spraying with hydrogen peroxide diluted 1-2x/wk - soak the soil in it  
I don’t water until the infestation is completely gone

I use hydrogen peroxide with every watering at a ratio of 1:4, but that uses a lot of peroxide. Your method of spraying the peroxide mix weekly sounds appealing. Do you spray your plants with this whether they’re dry or wet? I’m concerned about overwatering some plants if they’ve already been watered a bit earlier.  
TIA. 😊💚🪴

Hey I’m sorry I’m just seeing this now!! But I usually let the soil dry out for the first spray and then cut down on watering altogether do the spray weekly until the problem is gone!
