Some years ago, I was stung on theinside of my upper thigh by a scorpion. NOT close to MY "junk".
We were 100 miles from a decent clinic, chasing havelina in Arizona. The thing crawled into my sleeping bag.
It hit a vein and I am going to tell you that the pain was incredible! I would chew my foot off before going thru that again. I got VERY sick! I understand that different areas have more or less poisonous ones that others.
I've also been bit twice by black widows, once on top of my foot and once in my armpit. Those bites are painful also, but nothing like that scorp!
I actually shot a scorpion, on the floor in my house, with a 12 ga, 00buck. That episode cost me $1200 in home repair.....money well spent and I would do it again right now!
And, just so it's clear, that tarantula would get shot off my leg, regardless of "collateral damage".......
We have 3 cats....not much gets away by crawling around my house now.
