Nope, this is one of the least offensive members of the cobweb spider family, the Triangulate cobweb spider. This spider has fangs which are very small and angled in such a way that they cannot bite humans. In spite of the fact that they are related to widow spiders, there are no know cases of a bite in a human from this species.

To compliment L.N.'s response, these are totally harmless house spiders, I keep them around for pets, and have even played with them.
