In the USA, American International Pictures released the film on 27 October 1965 as the first feature on a double bill with Mario Bava's Planet of the Vampires (1965). In the UK, the film was trade-shown on 4 February 1966 and released on the 20th of that month, supported by Roger Corman's film The Haunted Palace (1963), which is also based on a Lovecraft story.
In their book Lurker in the Lobby: A Guide to the Cinema of H. P. Lovecraft, Andrew Migliore and John Strysik call Die, Monster, Die! a "textbook example of the walking-around-endlessly-in-a-big-house school of filmmaking". G. Noel Gross, writing for the DVD review website DVD Talk, writes: "The plodding plot would be more painful if the flick were longer, but the intriguing meld of gothic horror and contemporary sci-fi is hard to pass up".
