Comments & ID Thoughts
I looked up some pictures of spiders and the one I think to be on the picture I took is a black and white "SPINYBACKED ORBWEAVER". And there are a lot of these at my house.I would like to know if they are poisonous, for I have children. I've even seen a red and black one. Even a Black and blue spider but not related to the spinybacked orbweaver, to this day I have no idea what kind of spider it was. I wished I would of took a picture of it when I had found it in my car.

Hi, welcome to Spider ID. 🙂 Your ID is right, you have a Spinybacked Orbweaver (Gasteracantha cancriformis). Like most spiders they are venomous but not considered to be of medical concern. They are beneficial and help to keep the insect population in check. They are also timid and reluctant to bite except in self defense.
