I'm still kicking myself for stomping on a spider out of reaction. I had just walked out the kitchen door at the lake cabin up in Southern B.C., there was a small hallway where the door to the basement was then the backdoor. I closed the door behind me and turned around and saw movement on the floor, there was the biggest jumping type spider I had ever seen, had to be the size of a nickle easy, muscular and squat, with orange and black striped fuzz all over him. I didn't even think and stomped on him with my bare foot, just a gut reaction thing. Even smashed he was a good sized critter, I checked him out and he did have eight legs and good sized palps and fangs. I asked my neighbor if he had ever seen one since he was a lifelong resident of the area, he said he had heard of a spider that looked like that and they were called "cow killers"....I've looked through every book and never seen anything that looked like that one. I've been bitten by spiders twice that required treatment, cellulitis is the biggest threat, other than that I just leave them alone as long as they are not in the house. You gotta remember to shake your clothes out if they have been hanging around the outside for very long, thats how I got one of my bites...they figured it was either a hobo or brown recluse.
