While I'm not thrilled with spiders in general, and will in fact kill Black Widow spiders with fire (my handy propane torch being the weapon of choice - a quick trigger pull & release results in a sufficient fireball to knock it down off of wherever it's at without igniting anything, and then I can step on it or just carbonize it as needed), these "wolf spiders" (I think it's more accurate than the absurd "tarantula" that my wife calls them) don't seem to cause any problems here.
Occasionally I find them in the house and try to toss them outside, but they usually find their way back out on their own (or the cat gets them) because we don't kill them, and I'm certain nobody's been bit.
I've seen them in the house up to a leg-span of about an inch, though I've found a couple outside with about a 2" leg-span (startled the livin' %$#@ out of me trust me). I'm pretty sure they mostly live in the ground, I see holes with a bit of gauzy lining.
