When I was 9, I was bitten on the leg by a Brown Recluse while playing in an old Oak tree. I didn't even feel it bite me. About 30 min later my leg felt funny, almost like it wanted to freeze up. Luckily, I got to the doctor in time. Had to take pills & couldn't walk right for a week. Not fun. 20 years later, I still have the little indentation on my leg and have had arachnophobia ever since... Irregardless, if I saw that in my basement, I'd probably kill the big one and capture the little ones to release into the wild. Then I'd pay a bunch of birds to come and eat them one by one...
