Don't know the answer to your question , but I do know they eat decaying

I hope not. About once a week we find one in the lounge, usually
crawling along the carpet. But one a few minutes ago really puzzled us -
it was a metre off the floor crawling up one of the lounge curtain ties!

We have no idea where they come from and how they get in (this is a 60s
built bungalow with suspended wooden floors over bare earth).

Odd. Anyway, they are completely harmless, and can be ignored. One of
my children (when very young) always called them woodlemice, and probably
ate quite a few.
