I have for the past few years been getting beetles randomly appearing every few months, When they are out ican find 10 a night but then dont see them for months again, Ive googled and nearest description I can get is carpet beetle but they dont look like them, they start off as tiny wee brown worm maggot tyoe things which grow and get fatter to about 1-2 cms long then I guess they shell and turn into the beetle, both are really dark brown in colour, mostly find them at my kitchen door but also been found in other rooms, always in the corners or around the skirting, theyt come out whenits dark and run away into nooks and crannys when I put the light on, ive just been lifting them and flushing them down the loo but would really like to get rid of them once and for all.

Any ideas what these are and how I get rid???

TIA
