A 3ft-4ft snake was found chilling in my office a few days ago. It was sitting curled up in a 5in x 5in hole in the wall where a bunch of network cables go into the wall. Thankfully it was a rat snake. When the snake was attempted to be caught it immediately went into the wall. We started cutting access panels in the wall and put a camera in the wall and chased the thing back and forth until it disappeared into the wall somewhere. Have not seen it since.
I ate one once and it made nice sashimi. Bled and iced immediately. Everybody calls them trash/bait, but I would definitely eat another one raw. I try a lot of fish people consider trash though and most of them are good.
Could be something to treat foot odor? I have soaked my feet in black tea to kill a stanky leg and one time it stained my toenails black. Not a good look.
