"[6] Davies played the doting mother of Private Frank Pike (Ian Lavender), Mrs Pike, in 30 episodes of the sitcom, with her storylines mainly involving her relationship with Sergeant Wilson (John Le Mesurier) and her "mollycoddling" of her son, much to the annoyance of Captain Mainwaring (Arthur Lowe).

[7] For the film version of Dad's Army (1971), Liz Fraser was cast as Mrs Pike.

Co-writer of the television series, Jimmy Perry, has said "It was a mistake...not to cast Janet in the role because the viewing public has come to recognise her as Mrs. Pike.

Her Dad's Army co-star Bill Pertwee said that she "spent her last days in a hospice and died peacefully" adding that she was a "lovely woman".
