A few weeks ago I found two beetles in the little spare room... the room where our cats used to sleep/eat/answer the call of nature a few months ago, which have since gone, and the room has been cleaned/hoovered, obviously not perfect but there's no visible remains of food/litter etc.
The beetles were just "dead" on the carpet

I then found another "dead" one in my bedroom, which is next door, around the same time...

I left a towel on the landing last night before bed and this morning when I went to put it in the washing machine this morning to my horror one of these beetles was crawling in it


And now to my surprise this evening there's another one, this time in the dining room, wriggling on its back.

The offending beetles are about 15mm long, black in colour, have 6 legs, and two "antennae".
Below is a pic of the one I found in the dining room, but this is AFTER I killed it by means of fire (lighter) so the antennae have been singed off. Can anyone identify it, i.e. why is it here, what it feeds on, how to get rid of them? It's not a big problem, but I HATE creepy crawly things like this.

The house is clean and there isn't anywhere I can access to my knowledge that has any of these things in, like a nest or anything, so I'm stuck as to where they're coming from, and why they're invading my house?!
I've looked on Google to try identify it there but had no luck so... any help appreciated please
