its a house centipede. they like to live in basements but find thier way upstairs sometimes. one of the most discusting bugs ever.....i fucking hate those things even more than spiders.
Those things are extremely efficient predators, and I can't find any information confirming that they will bite humans. If you have house centipedes then you must have plenty of other creepy-crawlies nearby, so it might be worth keeping around.
