My own experience with the same snake escaping twice in my home and being found the same day each time....plus reading literally hundreds of "escape stories" over the years here at BP.net.....I would say that when an animal escapes within your home, the chances of finding it again are very high. Sometimes it takes a few days, or even a few weeks, but far more often than not, we hear happy endings to such stories.

I had a friend who lost a rosy boa...it was gone for months and they thought it truly gone for good. He and his girlfriend decided to buy a new house...packed up everything and moved...and when they were unpacking in the new house, out pops the boa from one of their boxes! You just never know where they'll show up or when.

My recommendations for lost snakes:

Check the smallest cracks, spaces, holes...if you overlook a space thinking there's no way your snake could fit in/through there...go back and look again. They will astonish you with their abilities to crawl under/through/into tiny spaces.

Watch for items overturned or disturbed on shelves or along the walls.

Make the house as silent as possible and sit quietly, listening for rustling. Putting out plastic grocery bags along any likely routes can help. Do this in the late evenings, especially, as that is when they are most likely to be active. But at all times, be alert for any little sounds that are out of place.

If the snake just ate, it is very likely that it didn't go far from its home...and it has found a secure little hidey-place to wedge itself into and sleep off its meal....so you may not see or detect signs of movement for awhile. I'd continue searching especially in a 10' radius around the snake's enclosure.

Good luck!
