What is this house beetle?  It seems to be mostly located by my windows but have found a few else where.  Seem to be more active in the milder months - not much activity in the Winter.  About 6-8mm ish.

Dear Jo - This appears to be a true bug (Hemiptera/Heteroptera) in the family Lygaeidae, see http://tinyurl.com/n8cabue for an example (not the same species as yours). Bugs such as these often enter buildings in search of overwintering shelter, but do no harm there. If you fins them annoying, simply vacuum them up and dispose in the trash.

Hope this helps,

p.s - Hope you haven't been affected by the awful flooding in the Levels - images on BBC look dreadful...

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.
