Man, oh, man!!! SOOO glad I was not at your house today! Not sure I could stay there tonight if it wasn't found, either. As far as I'm concerned, a snake does not have to be poisonous, it can be green, it can "little", and still kill ya.....heart attack!
I live in the country, on a farm, in a converted "summer kitchen" of a 200 year old plantation house. I was told by the "big house" neighbor (who grew up here and had helped convert the "kitchen" into a cottage and lived in it for years) that he came home late (midnight) one night and saw what he thought was a shirt draped over the front door knob (in the dark).
Turned out to be a big old black snake which got into the cottage as he opened the door!!! He, of course, was a big ole farm boy and when he couldn't find where it had slithered off to after a search, went on to sleep and didn't see it again!
Now, of course, I'm hearing that story YEARS later, and still freakiing out, LOL!
I've been here for three years now and there's hardly a day in the warmer months that I don't think about that D snake when I open the shower door, or reach for something under the kitchen sink, or step out onto the tiny screened back porch to use the dryer, or open either closet beside the original fireplace, or go onto the front porch. I've shivered enough times now, you'd think just the shaking alone woulda helped me lose weight!
Thankfully the new "big house" neighbors have dogs, nice, quiet, friendly dogs, but enough to place their scent and activites around the property so that deer, oppossums (so gross!!), and snakes are no longer as prevalent as they were a year ago. Now my furbabies reside peacefully on the front porch, sleeping their days away in comfort.
Hope you get some resolution to your snake in the laundry ASAP!!
