I was just a tad at the time, but I clearly remember my maternal grandfather, a retired miner in Bisbee, Arizona, instructing me on the proper way to put shoes on your feet. First, he explained, was to hold the shoe upright, heel down, and bang it on the floor several times. After finding no scorpions dislodged from within, it would be safe to put on the shoe. I follow that practice to this day. Here in Arizona, scorpions are common throughout the state, and easily find access to homes.
Every now and then, I also find a scorpion in the tub. I believe they come up through the drain. I make it a point to check the tub thoroughly before turning on the water and getting in to take a shower. I will occasionally find one scuttling across the floor, and believe me, they move fast. If you're not wearing shoes, get one fast to whack it.
About 5 years ago I found one in the tub and made the mistake of trying to crush it with some wadded-up toilet paper. The little monster stung me on a finger of my right hand, and the pain was excruciating. I had to go to work, and part of my job at the time was working a computer. It was next to impossible because that finger was so numb. I could feel the poison working its way up my arm. It took me a little over a week for the numbness to go away.
About a week ago, the new quarterback for our Arizona Cardinals, Matt Lineart, was stung on the neck by a scorpion in his home. I guess he's tougher than most; he continued practice with his team.
I have seen scorpions crawl upside down on the ceiling. This is particularly scary, because they can drop down on your bed while you are sleeping. This is NOT a good thing.
Dogs are particularly susceptible to scorpion stings, as they love to bite at the insects. About 3 years ago, our dog Joe, who was then just a puppy, had an encounter. Here is the result. Thankfully, when we put him on an antihistamine for a couple of days, the swelling went down. He was a brave little fella.
