As other have said, it is a House Centipede. This creature is very common and has a wide distribution; although I never saw any of them until I moved from to Ohio. They feed on smaller insects which are typically considered pests, such as silverfish, opilones species and other arthropods which might cross its path.
These guys are often considered pests, but that is typically by people who are unfamiliar with them. I catch them (after letting my cats play with them for a little while) and take them outside. Like all centipedes, they are venomous but it is not harmful to mammals. Their venom might cause irritation, but I am not sure. I would have pull up some articles and do some reading, but you can do that by going to Google Scholar.
Hope this helps.
