Hi Craig,It could well be carpet beetle. I am seeing more and more infestations in recent years. Click on the link below to see some info I did for my clients. There is also a video produced by Manchester museum in the link showing the life cycle of the carpet beetle.http://designcare.co.uk/uncategorized/carpet-beetle-rise/I tend to swerve dealing with these infestations and leave it to Rentokill. They are notoriously difficult to eradicate.Nigelwww.designcare.co.uk/news
