Expert Response

Dear Client,

Your spider is most likely Steatoda grossa, often called the false black widow. It does resemble a black widow in shape but lacks that red hour glass on the underside of the abdomen. I can not tell what the size of this spider is, but I am guessing that it is not big enough to bite a human (puncture the skin). If it did, the bite would get your attention but it is not toxic like a black widow. Nevertheless, I would take precautions not to handle any big spider (>0.25 inches) to reduce any risk. Spiders outside the home are beneficial arthropods that will feed on other spiders and insects. Spider inside a home are almost always not appreciated, considered a nuisance, and can be captured in a jar and escorted back outdoors.  FMI, follow this link:

Thank you for your interest!
