Every scene in the film had to be shot twice in both English and Spanish in order to ensure that the dubbing in either language would match perfectly.
Warner Brothers paid the American distributor of the film, New World Pictures, to postpone its release so that it would not coincide with the theatrical release of their killer bee film, The Swarm (1978).
The bees used in this film had their stingers removed as a precautionary measure.
Footage of former President Gerald Ford is used from CBS Tournament of Roses Parade and Pageant (1978). He was the Grand Marshal in 1978's Tournament of Roses Parade in Pasadena, California. In this film, the bees attack the parade, but Ford is unharmed.
This is one of several films about Africanized honey bees (a.k.a. "killer bees") that were released during the 1970s' fear of, and fascination with, their predicted future invasion into the U.S. Southwest via South America in the early 1990s (which actually happened in the predicted time period, but not in the same ways the films had said it would, of course). Other films in this subgenre include Invasion of the Bee Girls (1973), Killer Bees (1974), The Savage Bees (1976), The Swarm (1978), and Terror Out of the Sky (1978). The last film on this list is the sequel to the third one on it.
