Devil's Coach-horse house call

[hugh74]

Hi,
firstly - apologies - know nothing about insects. Hence the question... please bear with me if it's a stupid one.

I just found a long, black, segmented insect in the living room, which, going by pictures I can find on google, looks suspiciously like a Devil's Coach-horse beetle.

If it is, is this something I should be worried about? And I mean in terms of house is 1930s build, there's a lot of original wood, and voids under the floors. I DON'T mean should I be worried that it's a harbinger of death, a Reaper, or anything like that... as interesting as those fables are!

Is there likely to be more of them which I just haven't seen? Do they nest/infest? Are they harmful?

Thank you so much for your help!
Hugh

Never heard of them being harmful the larvae live in old rotting wood I think not usually in houses I dont think you have an infestation problem..

Yes most likely a wanderer,the larvae and adult are carnivorous,an RSPB wildlife site lists the prey as"Fly larvae,insects,spiders and slugs".
