Found in farm buildings, barns, warehouses and granaries in Britain, and formerly widespread and probably not uncommon throughout much of lowland England; however in the 20th century was last recorded at Chiddingfold, Surrey on 3 June 1966 and was considered possibly extinct in the country. In Hampshire, an old record given in Goater (1974) from Beaulieu Road, New Forest is considered to require confirmation. In recent years it has been re-found in a number of scattered locations, including Wales (Flintshire 2017), Norfolk (2019), Shropshire (2016) and probably established in parts of Kent.
