Found bugs in baby corn snakes tank

[Pogie]

Was cleaning out the baby corn snake tank and found bugs. I know there are tons of threads about mites, I just read them all lol. So none of the ones I see posted look like the bugs in his tank. Mine look like tiny fleas, they are not round like the photos I've been seeing, but they are black. I squished one to see if it left blood. Nope, no blood.
Also none on the snake itself, or none that I seen. I soaked him in water to see what would come off him, and got nothing in the water.

So after I removed his bedding and washing his hides down with hot water I went to check Tyrions tank.
His bedding is full of these also. I did notice he was soaking in his water and someone said he might have mites. I checked him then and saw nothing. But then again he is black so it was hard to see.

I will probably treat for mites anyway just in case. But to be honest I really don't know what these are. I use aspen bedding. Thanks for any help you can provide!
