"The Deadly Mantis" was released in 1957 as a double feature with the spy film "The Girl in the Kremlin". "The Deadly Mantis" received mostly negative reviews upon its release. TV Guide awarded the film 1/4 stars, calling it "Lame rip-off of the sci-fi classic THEM!". Andrew Smith from "Popcorn Pictures" gave the film a score of 4/10, writing, "Devoid of anything fresh, featuring a tired storyline, an over-use of stock footage and peppered with lifeless characters, it’s no surprise to see this drop off the radar whilst true classics likes "Them!" and "The Beast from 20,000 Fathoms" reign supreme."
