I arrved last night and saw a small black insect on the window...then thought I felt a creepy crawler about....

I awoke this morning and see small insects flying about...they bite they fly if they get in my juice I'll die!
This is supposedly a pet free unit...I'm guessing someone didn't follow the rules.....
I'm also guessing these are fleas but I'm not sure if fleas fly...I know they jump....but I don't know about these winged things...
Does anyone have a clue what they could be.....I need to notify the property mgr...I have never seen these things...but I'm not liking it...
