Anyone else in the northwest deal with these? They are becoming a real problem in western Montana. I've never seen a more aggressive arachnid. I've literally been chased by them, and as the old saying goes "If you see one in your house, you've actually got hundreds of them." I've had to help "clean" up three infestations of them, one of them was literally in the thousands if not millions. My girlfriends sisters basement, was literally covered in them. We went down and it was like the floor was moving there were so many.
While I am usually a live and let live kind of guy, but an animal that has a nasty bite, and attitude, roaming my house just isn't really welcome. While some articles say their bite isn't as bad as people claim it to be, I've seen someone who had a bites all over their hand and arm from them. While not the flesh eating necrotic bite it was claimed to be when they first hit the area, it looked very nasty and painful. Large pus filled bumps, that sometimes got big enough to rupture on their own if she didn't have a doctor lance em first. :\
I once had one caught in a big old peanut jar I'd washed out to study it a little. They seem like a fairly intense species, but not one I'd ever want to keep again.
EDIT: For the record, I've also had to clean up a black widow infestation that was under an old semi trailer. I would much rather deal with the widows than the hobos, even though they are more dangerous.
