It is a black and yellow argiope. They are harmless orb weavers people find in their gardens.

All spiders are poisonous. You ment to say "Is this spider hermful to people." Right!!!

To the person asking about this spider in your garden and the sister in-laws home;Banana Spiders - This girl (the yellow and black one to the right is a banana spider. Banana spiders are consummate web builders. A single banana spider can place a web across a 12 foot wide trail overnight. The bright yellow web, is usually about 6 feet above the ground (just in the face of horse and rider) and normally has an area from 8 to 36 square feet.These spiders can grow very large. I have seen many with bodies the size of my little finger, and leg spans of over 5 inches. They catch lots of bugs in their webs. They often share their webs with other spiders. They normally do not bite unless you smack them first. If one lands on you, all they want is "off".A very large common spider in North America. Usually hangs in webs with its head facing the ground. It is brightly colored. Its venom is a neurotoxin similar to that of the black widow. However, its venom is not near as potent. Its bite causes local pain and redness with blisters forming. This bite usually resolves within 24 hours except for the bite mark. it is also known as the garden spider as another resondent answered and it will not kill you it is not strong enough but is nasty when bitten.
