Dealing with small black flies

[SWDK]

So recently I've been having an issue with these small black flies in my snake room and enclosures. The problem has gotten worse over the past month or so since the weather has changed. They almost look like fruit flies but a bit larger.

Has anyone dealt with flies like this or of another type? What's the best method to combat them? I'm going to hang up a few strips of fly paper, but that's only a shot in the dark to catch a few of them.

I spot clean my enclosures 4-5 times a week and do a complete enclosure cleaning monthly or sooner if the enclosure get funky.
