Can anyone help with identifying this bug. I found it in the bedroom at the back of chest of drawers and bedside cabinets. They seem to be on the wall and skirting board. I haven't found any on the mattress yet. But as far as i can tell they are darker in colour than bed bugs. When you shine a light on them they move.
Looks like Aridius nodifer (Coleoptera: Latridiidae - please don't start a debate about that nomenclatorial change guys - worse than Leptura by far).
This is a common stored product pest usually where commodities have gone mouldy - I should thInk that there is some damp in the area.
Well they are mould feeders so are only found in association with moldy (damp) things. They will not feed on fabrics, furnishings, foodstuffs or woodwork, but will feed from mould growing on organic materials such as these. A dust pan and brush to clear away any you see would be a start, followed by an investigation of the surrounding area to see if you can find what they may be feeding on (mould remember). They are not intrinsically a problem - rather a nuisance.
After much ambivalence I have decided to agree on your identification (there are some other contenders, all in Latridiidae Erichson 1842 (=Corticariidae Curtis 1829, =Lathridiidae Redtenbacher 1845) - also note that Corticariidae predates Latridiidae ). At first I didn't understand how you could even try to identify that little dot - but then I downloaded it and the image was much larger than when I only clicked it (peculiar, I've never noticed that before) - I have added it below (I made it just a notch lighter).
On your statement on nomenclature I only have to link to this page and say that I agree .
