Best Giant Bug Movies of All Time

Humans have always been intimidated by species larger than themselves. Hence large aliens, dinosaurs, and predators make up some of the favorite features of the sci-fi/horror genre. One of the lesser-featured but equally creepy is giant bugs that come in many forms and sizes. Here we take a look at the 15 best giant bug movies of all time that managed to intrigue us the most:


15. Invasion of the Bee Girls (1973)

Invasion of the Bee Girls 1973 Movie

An eccentric idea put forward by the writer of Invasion of Bee Girls women can exhaust men sexually to the point of death. Lead actress Anitra Ford dons the role of a scientist, Dr. Susan, researching bees.

Mysterious deaths lead to government agent Neil (William Smith) investigating the matter. He finds Dr. Susan has created monstrous women, who seduce men with their beauty and kill them.


14. Eight-Legged Freaks (2002)

Eight Legged Freaks 2002 Movie

Eight Legged Freaks is written and directed by Ellory Elkayam as a sci-fi comedy with a simple plot, a spider fanatic’s blunder of causing all spider species to escape coupled with a chemical spill that causes them to grow to the size of a small truck.

David Arquette features as the lead in this movie, Chris McCormick, who returns to town after 10 years and still has a thing for the pretty sheriff. Together the sheriff (Kari Wuhrer) and Chris must lead in a struggle against the monstrous spiders.


13. The Mosquito (1995)

The Mosquito 1995 bug film

Our hatred for the buzzing, the blood-sucking nuisance of an insect, the mosquitoes, is universal. Imagine these annoying flying, malaria-causing beings becoming gigantic. Not a very pleasing thought.

Writers Tom Chaney and Steve Hodge, and director Gary Jones play on your worst fears in this flick where an alien dump helps mosquitoes become vulture-sized, human-killing beasts. Lead stars Rachel Loiselle and Tim Lovelace along with others look to defeat these mutants.


12. Kingdom of the Spiders (1977)

Remember how Ron Weasley follows the spiders into the woods only to find his worst nightmare in giant sizes and huge numbers (Harry Potter and the Chamber of Secrets)? Kingdom of Spiders, directed by John Cardos, has a similar story.

The death of farm animals leads the vet Rack Hansen (William Shatner) along with Dr. Diane Ashley (Tiffany Bolling) to investigate the matter only to find that gigantic killer spiders have overrun the town.


11. Honey, I Shrunk the Kids (1989)

Honey I Shrunk the Kids 1989 Movie

Here is a movie where instead of any bugs getting super-sized, the reverse happens and four kids are shrunk to nano-versions by an electromagnetic shrinking machine in a cartoon-like blunder. Although Joe Johnston’s venture did not receive high ratings from credible movie sites, it does have a good storyline and applaudable special effects.

The four shrunk kids’ adventure is amusing as they brave their way past routine things that become monstrous for them due to their miniature size. Honey, I Shrunk the Kids won the BAFTA film award.


10. Mimic (1997)

Director Guillermo Del Toro’s brilliant visual sense helps in putting Mimic ahead of its competitor movies with similar plots. The movie features a very attractive Mira Sorvino as an entomologist, Dr. Susan Tyler (Academy Award and Golden Globe winner for her role in Mighty Aphrodite).

She comes up with a genetically engineered bug that mimics and kills cockroaches, which are spreading a plague causing the deaths of children. Thought to be sterile, the bugs somehow evolve and start mimicking their new victim – humans.


9. Starship Troopers (1997)

Starship Troopers are based on Robert A. Heinlein’s science fiction novel of the same name. It projects a futuristic world where kids are sent for military training to fight the alien bugs in space, who are bent upon destroying the human race.

Leading roles in Paul Verhoeven’s venture are taken by Casper Van Dien who plays Johnny Rico and by a sultry American fashion model, Denise Richards, who plays Lt. Carmen Ibanez.

Playing Johnny’s best friend with psychic powers is Neil Patrick (everyone’s favorite character, Barney Stinson from HIMYM). Starship Troopers was nominated for an Oscar in the Best Visuals category and surely ranks amongst the most action-packed giant insect monster movies ever.


8. Naked Lunch (1991)

Naked Lunch 1991 giant bug film

Naked Lunch is based on William S. Burroughs’s novel and his life. The movie has a bizarre plot as the protagonist, Peter Weller, plays a bug exterminator who also happens to have a habit of getting high on bug powder, along with his wife.

He accidentally shoots his wife one day (a real-life incident from Burroughs’ life) which seems to trigger paranoia and possibly Schizophrenia. His typewriter somehow changes into a giant cockroach from whom he takes orders and ends up involved in a delusional mission.


7. The Mist (2007)

The Mist Best Giant Bug Movies

Frank Darabont, held in high esteem for his gem of work – The Shawshank Redemption, has directed this sci-fi-horror movie which has done surprisingly well at the box office and received great reviews on IMDb.

It is based on Stephen King’s novel where a mysterious mist on the lake baffles no one until a power outage forces many to turn to the supermarket including Dave Drayton, his son, and his neighbor.

Rumor of secret military operations and vicious insect beasts with tentacles, knocking on the windows of a supermarket has everyone frightened. Will these trapped people survive, watch the movie to find out. And, yes you must have heard about the ending of this film as it features one of the most shocking film endings ever.


6. Tremors (1990)

Tremors (1990)

Director Ron Underwood produced this epic comedic sci-fi for a mere $11 million. Giant creatures with tentacles that move inside the earth and are bent on killing humans are the reason seismologists (played by Finn Carter) are getting unnatural signals.

5. Slither (2006)

It is up to his wife, Starla Grant (Elizabeth Banks), and the Sheriff to save Grant and other people from alien slugs that Grant is nesting.


4. Phase IV (1974)

Phase IV 1974 Giant Bug Movie

Incidentally Saul Bass’s last movie as a director, Phase IV pitches ants against humans. An event in space causes ants to become super intelligent and start a vendetta against humans.

Without a definitive ending, the movie, apart from being sci-fi horror, has been credited as being a piece of art that reflects ants’ view of humans.


3. Tarantula (1995)

Tarantula 1995 Movie

This 80-minute horror movie, directed by Jack Arnold, features a titanic tarantula (a huge spider) that is on the loose, causing the deaths of people and cattle.

2. The Fly (1958)

The Fly (1958)

Based on a short story by George Langelaan, The Fly’s theme is very intriguing. Instead of bugs attacking humans, the plot is about an experiment going wrong. A scientist is experimenting with teleportation and is getting successful results.

    Hi, I have been unable to find the title of an old movie (50's/60's?) where giant roaches attack a town. My best recollection is of the Army inside a cave and one giant roach eats the flesh off the head of a soldier. Any idea what the movie was?
