Croft said of her work at WLW, "from 1935 to 1939, I played parts with every kind of voice and accent: children, babies, old women, society belles, main street floozies – everything.

She also appeared in frequent guest-star roles on Lucille Ball's My Favorite Husband, the beginning of their later professional and personal relationship.

[4] In addition to her work with Lucille Ball, she was a frequent guest star on other television programs, including Howard Duff's adventure/drama series Dante in the 1960 episode "The Misfortune Cookie".

She was a regular on at least two other series, as Clara Randolph the ebullient neighbor with the shrill voice married to Joe Randolph played by Hollywood veteran Lyle Talbot on The Adventures of Ozzie and Harriet, and on Our Miss Brooks on CBS, in which she reprised her radio role as Miss Daisy Enright, the title character's rival.

Late in the weekly run of the original I Love Lucy series, the major characters moved to Connecticut.

Croft had previously had a recurring role as Audrey Simmons during the show's early seasons set in Danfield, New York.
