Yeah I used to be worried about spiders way back in the day. I Read up on all kinds of stuff.
The NW pretty much doesn't have anything to be afraid of.
You're also not going to be able to idendify most spiders by looking at pictures on the web.
The Brown Recluse (Violin Spider), the Hobo Spider, Wolf Spider, and our common large Brown House spider all look almost IDENTICAL. Other than being slightly more harry.
The only way to tell is to look at them under a microscope. The rule goes, Big and hairy GOOD, smaller and no hair bad !!!
This hairy monster is commonly found in your tub or sink. It's harmless.

But to put your mind at ease, catch one and get it looked at by a professional. Also try a Google search of Tegenaria.
