Although there's no approval rating on Rotten Tomatoes, the Want-To-See score is currently 13% and was met with mixed to negative reviews from critics and audiences.
David Cornelius from Hollywood Bitchslap though the movie "looks like it was a gas to make. To watch, though? Not so much." Super Reviewer Bruce Bruce claimed that "this movie wasn't all that bad. I've seen worst. It's Giant Ants that are eating people. Funny how Old School Black and White Horror is always better, but still this film is worth a rainy night."
