I got rid of mine by breaking apart and sprinkling 1/4 of a mosquito dunk around a 3 gallon pot. Took them out in 2 days.
^ interested in your method..
I was reading up on bti's.. it was saying the larvae eat it.. I wonder if there attracted to it in the first place.. like they put something in it to attract them.. and it seems you gave them a nice buffet for them then... haha. then I kinda also wonder, how the bti can reach the bottom of buckets for people who have sneaky ones.. as it wouldn't seem it couldn't get to the bottom if it is resting on the top surface???
also it was saying, don't apply to water that has copper ( nutes might have trace amount? ) and chlorine.. so anyone knows for future
also wonder if it does anything in way to off balance other bacteria in the media???
You can look for products containing bacillus thuringiensis israelensis like Neudomueck f.ex.
They sell those products to keep ponds and stuff mosquito-free and it works with those gnats as well.
The larvae of the gnats in the coco/soil eat it and then it dissolves their digestive system.
then get the adult flies with yellow stickies and break the cycle with a perlite top layer.that worked for me perfectly.
sounds really harsh, but it does the job efficiently and it's not affecting the buds, so you can use it even during last weeks of flower.
Mine were all gone after a couple days.
good luck &take care

I had a battle with these bastards in my last grow/current mother plants. Finally got something that works great and isn't full of pesticides/chems - a wine trap!
Simply take some red wine (cider vinegar works too I read), pour into a shallow and wide dish, and stir in a little bit of dish soap. The wine and vinegar attract the gnats and when they land on the surface, they can't get out due to the surface tension of the water being broken from the soap. Place the dish under the canopy, and leave it for at least a week or 2, or for good since it seems like they always come back this time of year. Add a little water every couple days as it evaporates.
This works for fruit flies too, and I found out it works for fungus gnats too!

Gnatrol works well.
