Little Black Bugs With Wings In Substrate

[Snake.pics]

Hello!
I keep 2 ball pythons, a male Bengal Pastel and a Normal Female.
I have been finding little black bugs with wings in their substrate. I know they are not mites because they have wings and can fly, and only a few have appeared. I don't know what they are and am confused. I have been keeping ball pythons for 3-4 years, and have never seen them before.

Any ideas what they are?

If someone could answer soon that would be awesome!

Thanks!

Pictures would help but my guess is male termites just off that description.

gnats? really sounds like gnats. and they may be attracted to feces if the cage hasn't been thoroughly cleaned in a while/ substrate changed out.

mites, gnats, fruitflies
pics will help IMMENSELY
no matter what they are, substrate change and cage/enclosure clean for sure

*future precautions
if able to, try storing your substrate in your freezer for at least a week before using it.
the freezing will help kill MOST insects that could be dormant in the substrate

Also, what are you using for substrate?
