So... I found a black spider, about thumbnail sized in my bedroom on my curtain. It had a bright yellow perfect triangle shape on it's back. Also the legs were striped black and yellow. I want to make sure this thing is not dangerous!

What kind of spider is this? It's on our patio outside. http://i214.photobucket.com/albums/cc200/hdawson1/spider.jpg

I found this spider in my room, I live in Minnesota, and this spider is about half an inch in length, has slightly furry legs, and very hard exoskeleton. It's also not brown, its black, and those lines are white.

We found a huge spider with a white sack attached to it. When we killed it, goo squished out. Do you know what kind of spider this is and is it poisonous? Also, was the spider going to have babies? Is that what the white thing was?

Hi can anyone please help me to ID this spider that I caught in my house its huge it could be a giant house spider or a male hobo spider. I'm not sure though I would be gratefull for a second opinion.
