Nasty Alien Insects From Sci-Fi You Wouldn’t Want to Deal With — Ever!

Have you ever wondered what it would be like if some human-eating insects from other planets actually visit Earth? Doubtless, even the toughest pest and termite control in town might tremble at the thought! And why wouldn’t they? These extraterrestrial creatures are mean and vicious, and they’re willing to do whatever it takes to ensure their survival—and our extinction. Listed below are just some of the alien bugs that appeared in various sci-fi flicks and games, each gruesome and nasty in its own right.

Klendathu Arachnids

(Starship Troopers)

Klendathu Arachnids

Also called the “Bugs” by humans, the Klendathu Arachnids aren’t really arachnids (not by Earth’s standards at least). They’re large insectoids capable of pinning down and ripping humans with their razor sharp pincers and mandibles. And like most insects we have on our own planet, they also operate under a single command. Unlike our own pests, though, these guys are capable of firing spores across orbits, spreading Arachnid eggs and conquering the planets in one go. They’re also capable of directing asteroids to other planets as a means of long-range attack, as seen in the film when they used this technique to destroy Buenos Aires and kill millions.

The Zerg Race

Apparently, alien insects make good antagonists in games, too! Like the vociferous Zerg race in StarCraft, for instance! Created by an alien race known as the Xel’Naga from life forms found in the planet Zerus, these alien bugs have the ability to absorb the “essence” of the creatures they kill, transforming itself in the process. In order to better control these experimental race, the Xel’Naga also created the Overmind to collect all the consciousness of the Zergs and bend them to its will. Ironically, though, the Overmind used the Zerg race to cause the destruction of the Xel’Naga. And even after killing off their creators, the Zergs are hell-bent on achieving genetic perfection, targeting humans and other races that come their way.

Edgar the Bug

(Men in Black)

Edgar is a member of a cockroach-like race that’s at war with other alien races. Searching for an important political enemy and an even more precious artifact, he crash-landed on Earth and after killing and “putting on” some random farmer’s skin (he also took his name, by the way. Identity thief alert.), he killed the refugee, took the object, and almost caused the destruction of Earth. If you think your normal-sized household cockroaches are gross beyond imagination, wait until you meet this guy—or any of his buddies for all that matter!

The Nematodes

(Red Planet)


The Nematodes are fictional Martian insects featured in the sci-fi film Red Planet. In the film, the Earth was on the brink of environmental collapse (largely thanks to us humans as usual). In an effort to make the planet Mars habitable, algae has been planted on its surface to create the suitable atmosphere. Unfortunately, the Nematodes can’t resist veggies and seeing a field of mouth-watering algae, they dig in vigorously. Their only known weakness is that they’re highly flammable; and setting one on fire can cause a chain reaction that would kill all its companions. Oh, and they’re not all that bad—as you’ll find out when you watch the flick!

Luckily for us, these pests only exist in the imagination of our movie makers. And hopefully, we won’t encounter any extraterrestrial insect in our lifetime! However, it would be better to have your local pest control on speed dial . . . just in case.

FAKE OR REAL? 4 Movie Bugs You Hope are Fictional

eight legged freaksRemember the films your mother warned you not to watch, but your brother kept on pestering you to? Yeah, your brother was a total pest especially since you ended up watching films that ruined your dreams at night. You used to adore bugs, but now you can’t find any reason to anymore. Sorry for bringing up the memory, and especially for what we’re about to do. See, we’re going to recall the bugs of the films that you used to loathe—even until now.

“Them” Ants

Termite control keeps your termite problems at bay—even in the big screen—but filmmakers cannot resist making ants that you just have to add to your list of phobias.

The ants of the 1954 film “Them” are not what you would hope them to be: gigantic and man-eating. Now this isn’t a picnic. See, what happened was an atomic bomb test went clearly wrong, and it affected the appetite and structure of the ants in America. If you look at it, it isn’t impossible to happen, especially since atomic bomb technology isn’t still forgotten. So you may be better off thinking that the ants of “Them” are possible to exist. Just think about it this way: the knowing can prepare for the coming.

Eight-Legged Freaks

With the tagline: “Do you hate spiders? Do you REALLY hate spiders? Well they don’t like you either,” this 2002 film already gets to you. It’s scary! And not just because spiders are scary, but more because this film had said that it’s possible for spiders to grow as big as your cars and as ferocious as hyenas.

The premise is familiar; it’s much like “Them”, wherein the spiders get exposed to a noxious chemical that transforms them into human-eating monsters. But since eight-legged freaks are involved, the scare is greater. Now is that possible? Same as above, it may be. And are we doomed? Best to think that it is likely.

Deadly Mantis

Nothing can be more frightening than the promise of death. But for that promise to come from a praying mantis, now that just tells you to beware. Mantises are not really a threat to humans, right? But in “deadly” form, you have to rethink the answer to our previous question.

In this 1957 film, scientists discover a prehistoric mantis frozen in ice somewhere in the Atlantic. Now if they were you, you’d leave it alone, but since they’re not, they cannot help themselves from letting the mantis loose. And prehistoric mantises, like other bugs in the earliest days, were giants—bigger than humans, and with an appetite to match. It is definitely a no to let them live with us today. Or else we’d be living underground.

The deadly mantis may not exist today, but you’re not really sure it isn’t hiding somewhere in our ice caps, are you? Pray those won’t melt, and stop contributing to our global warming troubles—or else.

The Fly

Yes, you remember this—and you hate that you do.

The popular 1986 sci-fi film is not for most of our tastes, especially since it involves a gigantic fly. Some of you might think that’s not necessarily creepy, since you’re used to how flies look, but see, David Cronenberg made sure that his fly would be less than freaky. It’s not just a big, big, big fly—and that’s already gross—this is a human/fly. It was a man trying to teleport himself, but ends up mixing fly DNA with his; an abomination that makes you not want to sleep, and eat. And what’s worse is that Cronenberg’s fly is mad. Just imagine what it can do.

Now for your friends dreaming of time travel technology in the future, make them watch this film. If they don’t stop encouraging world-renowned scientists to go forth with the technology, the fly may just come soon.

Sure, bugs can be the annoying pests of your home, but take it easy on them alright? You’ll never know, they may turn into the monsters of the movies and prey on your very being. Be afraid. Be very afraid.
