Help identifying very tiny bug

[priyas21]

I am seeing several very tiny (<0.5mm) bugs behind wooden kitchen cabinet. I think they have a colony in the space between the wood and the wall and some they are now crawling out from there. They have legs like a mosquito but their bodies are very different. Like miniature house flies.
They are so tiny I am not able to focus on a single one using my phone cam but still managed to get a few pics:

Please help identify this bug and suggest what would be the best way to get rid of them.

They are probably fungus flies (Mycetophilidae). Do you have patted plants in the room? Their larvae feed on fungi growing on soil.

I don't have any plants inside the house but I do have a small garden outside. Also, I do see some mold growing behind the cabinet. May be that's what is feeding them. Would you say a spray of fungicide formulation that is used on crops such as carbendazim 12% + mancozeb 63% combo should fix this?

Thanks a lot for the help.

I said "fungus fly," but "fungus gnat" seems to be the English name for them. I'm not sure if they feed on mold on walls. As far as I know, the larvae live in soil. I don't know much about pest control, so I cannot tell if the fungicide formula you talked about works for them. If you google, you'll find a whole bunch of information on how to control them. I'm sorry I'm not of much help.
