Its only a black widow, I’ve had one living in my bathroom window now for about 8 months(I think its the same one, I talk to it while I shower). The screen is part of the wall so it can only go out(1968 double wide, classy!!).
A friend of mine used to work at NMSU and they did a survey to see how many black widows they could find on the very busy campus, they went around 1 building and found 1200 black widows within 3 feet of the base/foundation of the one building.
You really have to screw with them to get bit, though, I have noticed they love mailboxes and that is probably a bad place, especially when you send your kid out to get the mail.
Now the spider I saw the other night at the shop(I stay there a few nights a week) scared me, about 2.5 inches around, beautiful dark fuzzy grey with black stripes. Reared back and postured much like a scorpion(4 legs on the ground and 4 in “fighten” position). Then jumped about 18 inches in the air and did a backflip, then gave me the posture again. Rinse, repeat, several times, then the slipper of death squished him, he looked too dangerous.
Then the night before that there was the whip tail scorpion (vinegaroon), about 3 inches long without the whip tail. I played with him for a bit, he squirted his vinegarie goodness and then I let him wander away under a machine to go eat things that I am actually scared of.
Back to the black widows, if you have them, you’ll never get rid of them, you’ll very rarely see them, but just be careful sticking your hands into dark places you haven’t been in a while, a mailbox is a bad place and I honestly wouldn’t be surprised if most black widow bites came from mail boxes, not a spider to play with, tarantulas are not a problem, but the black widows get the squish.
