Identification (Fruit Fly, Gnat, Or Fungus Gnat?) & Remedy?

Can someone Identify? (Fruit Fly, Gnat, Or Fungus Gnat?) I think there from my soil I ended up using.. Black Gold Organic. I normally don't use this soil it was free from a friend so i ended up using it. now about four weeks into the grow i have these bugs flying around my tent and sitting on branches and leaves. i'm about 2 weeks into flower so i don't want these getting stuck in my buds.

I also need some remedy's to rid them, im thinking of using a sticky fly strip or maybe a bug strip or if i have to maybe a spray but that is a last resort.

Cant say for sure, cant see them that good but maybe fungus gnats....... Try letting your soil dry more before watering. Maybe some 3% peroxide at a 5 to 1 ratio with water, make a spray and spray on the top your soil to help with the larvae and some yellow sticky paper for the adult ones...... If you dont wanna use peroxide then try some neem oil, good luck.

Throw some of these up, cheap

Diatomaceous earth on top, and let it dry out well.
