I recall hearing a story on TV. I don't remember what show it was, but it was quite awhile ago. A couple was having trouble selling their house because some 20 years previously their tarantula had escaped and was never found alive or dead. Over the years there was an occasional dead desiccated mouse that might have died from anything, but also could have been fed on by a hidden tarantula.
The sellers couldn't imagine that it would still be alive after all this time, and they didn't find all that many dead mice (not nearly enough to represent regular feeding). Yet, they never found it dead either. And they couldn't guarantee that it wasn't still somehow living inside a wall or ductwork and coming out to feed.
They mentioned that there was this one couple who absolutely loved their house and was set on buying it, until
they told them about the tarantula.
I've no idea if they ever managed to sell the house, but I imagine that if they could never find a buyer, demolishing the house would have to be an option.
I know that I'd
never sleep in a place where there was any possibility that I might wake up with a tarantula on my face.
