huge spider in my house…is this poisonous?
Can you please identify the spider in the attached picture? To give you an idea of the scale, the picture in the frame is an 8.5” x 11’ (not including the matting and frame around it). Thank you for your help.

All spiders are poisonous since all spiders have venom, but that is not a cause for alarm. Most cannot bite through human skin and most do not have venom strong enough to have much more than a mild reaction like a mosquito bite (one not containing the West Nile Virus). This is a Huntsman Spider, Heteropoda venatoria, also known as a Banana Spider. Nephila clavipes, the Golden Silk Spider is also called a Banana Spider. We have not posted a photo of Heteropoda venatoria in a very long time. We have many images among our spider archives. Heteropoda venatoria has a near worldwide distribution in warmer areas with ports. They arrive by ship thereby increasing their range. Heteropoda venatoria is not a dangerous spider despite it large size. They are hunting spiders that do not build webs and they have nocturnal habits. In many tropical countries they are encouraged to cohabitate with people since they feed on cockroaches. This is a male.
