Steatoda triangulosa
(Triangulate Cobweb Spider)

Hi, I think it is Steatoda nobilis, a Noble Widow. Another common name is Skull Spider, you can see the skull mark on the abdomen. The “jaw” is toward the spider’s head. It is one of the species referred to as False Widows in family Theridiidae. They are related to Black Widows but their venom is vastly less potent to mammals. They aren’t anything to worry about. They prefer to avoid light and people.
