Yeah nasty little creatures they are.

Its actually a male Hobo Spider Tegenaria agrestis

They are highly aggressive and venomous/ or is it poisonous for spiders? Not sure lol.

I have been bit before and it literally eats a hole in your flesh. Mine wasn't too bad. I had some swelling, lots of redness and then it blistered and broke open and oozed. I had a hole in my arm for a long time. Now you can barely even see the scar anymore.

I felt like absolute crap for about 2 days, almost like I had the flu, but worse.

Here is a link, they are mostly in the Northwest I think. Experts seem to think they were brought over from Europe through shipping and landed in Seattle, then moved west from there.
