Here are a few pictures of spiders I've seen in and around my house. This first one was outside the back door making its web between a tree and the house. Unfortunately, the camera flash pretty much ruins the image, but hopefully you can still get an idea of what it was like. This spider was maybe three inches from leg to leg and had thick limbs that almost looked like armor plating. This next one was on the lower part of the pantry door in the kitchen, I grabbed a brand new broom we had and poked at it trying to either swipe it off or kill it. When I did that, the spider got forced/knocked inside the plastic wrapping over the broom bristles (it was literally brand new), so I took the broom outside and shook it off. The spider then crawled away, seemingly unharmed.
