Black Hard

What kind of bugs are these? They are black, hard shelled, visable, and they jump high and they bite?
We live in a these city apartments…
They are about the size of end of a pin. They jump and the are hard to kill. They have black bodies.
Fleas are more brown than black. There are many other insects that jump and bite. A hard shell could mean its a beetle. Without additional information it would only be a guess.
