I just wanted to say that if you do find a snake inside, make sure you or someone else keeps an eye on it from a safe distance.
If you take your eye off a snake, it will hide somewhere and then you'll have devil of a a job of trying to find it.
The snake, on realising you are there will most likely want to hide, and you, knowing the snake is there, will want it outside for sure.
In my volunteer wildlife rescue days, I was trained to remove and relocate non-venomous snakes from homes.
Relocation often meant releasing the snake into a protected area, within 50 metres of the catch site. Some snakes are territorial, like the non-venomous carpet snake that lives in our shed or in the pipe behind the shed. Been there for over three years now.
Venomous snake removal requires additional training and I left those well alone and called a trained person to help.
I learned that many of the reported 3000 annual snake bite victims in Australia are bitten because they were either trying to relocate or kill the snake themselves.
Don't take matters into your own hands. Snakes are fast, blindingly so, much faster than you, and faster than your eye can see. Best to leave them alone and get trained and qualified help.
In Australia, licenced snake catchers can relocate snakes from inside homes. Sure, you'll pay a few dollars, but that's a lot cheaper than possibly being bitten and paying doctors, ambulances, etc which will most certainly happen if you get bitten.
Sadly, about two people a year die here from snakebite. More die from bee and wasp stings.
The road toll is well over a 1000 people annually, to put risks into perspective.
Cars and inattentive / careless drivers and roads are by far, the biggest risks walking the Camino apart from walking or falling injuries.
Buen Camino!
