Top 10 Most Hated Animals in the World (Pictures & Facts)

It’s safe to say that animals are loved in the modern era, as we understand their importance to our emotional well-being. 

However, some creatures aren’t as beloved as others. Whether it’s because they’re dangerous, scary, or just plain annoying, some animals are universally hated by most people. 

We’ve gathered a list of the world’s top 10 most hated animals and why they’re so disliked to see whether they deserve the hate they receive.

Top 10 Most Hated Animals in the World

  1. Mosquitoes
  2. Spiders
  3. Sharks
  4. Jellyfish
  5. Bats
  6. Rats
  7. Wasps
  8. Snakes
  9. Cockroaches
  10. Raccoons

We’re starting off strong with what’s probably the most hated insect on the planet – the mosquito. Did you know that the mosquito is effectively the most dangerous animal in the world

In fact, it is estimated that this creature is responsible for billions of human deaths throughout history. Even today, the animal kills almost a million people worldwide every year.

However, unlike a wild cat on the hunt or a venomous snake, the mosquito doesn’t kill humans directly. Instead, it carries terrifying infectious diseases, such as malaria, Zika virus, and the West Nile virus. 

Not only a mosquito is unassumingly dangerous, but it’s also arguably the most annoying animal in the world. We’ve all had a lovely, warm summer’s eve be disturbed by a swarm of these buzzing creatures. The infamous mosquito sound is highly irritating, and we all know that a bite is imminent. 

Unfortunately, most of us are aware of the discomfort of a mosquito bite. When it’s feeding on our blood, a mosquito injects saliva into our skin, which causes our bodies to react with an itchy bump that lasts for days. 

So it doesn’t come as a surprise that these creatures are at the top of our list of the world’s most hated animals.

Up next are spiders. There are over 50,000 species of spiders worldwide; some are more dangerous and terrifying than others. However, no matter the species, a fear of spiders is one of the most common phobias in the world. 

It is estimated that between 3% and 15% of the population suffers from arachnophobia. Meaning these arthropods are universally disliked. 

But unlike mosquitoes, spiders aren’t as dangerous for humans as you may think. Even though almost all spiders have venom to paralyze their prey – out of the 50,000 species, only about 30 produce enough to harm a human being. 

Not only that, but they are also great at keeping pests under control. They are predators, and their usual prey includes moths, roaches, and other annoying insects. 

As a result, despite their reputation, spiders aren’t as bad as some may think! 


big shark in the water

Following the release of Jaws in 1975, the entire world was terrified of the shark. After all, they are horrifying, giant beasts with up to 3,000 teeth that can tear you apart in minutes. 

A true apex predator, sharks are one of the most dangerous animals on Earth… Right? 

Well, not really. The hate this marine animal receives is irrational and primarily popularized by the movie mentioned above. (source)

Out of 300 known species of sharks, only about 12 have attacked humans. Unlike popular belief, sharks don’t really like to eat us as they don’t consider us their prey. In fact, most shark attacks on humans are because they confuse us with seals. 

To conclude, despite being one of the world’s most hated and fear-inducing animals, most sharks pose almost no real threat to humans. 


pink jellyfish on the water

Depending on where you live, you’ve probably had a nice day at the beach cut short due to a jellyfish invasion. These creatures live in waters all over the world, and most people have had a few uncomfortable encounters with them. 

Much like spiders, jellyfish inject venom into their prey. However, unlike a spider bite which is usually unnoticeable to humans, a jellyfish sting is very painful. 

As a result, it’s safe to say that this animal is much disliked. There are few scarier feelings than enjoying a nice swim in the ocean and noticing a jellyfish creeping up on you. 

Luckily, jellyfish are easily avoidable, even if that means that the beach day is over. 


bat hanging upside down

Like many other animals on our list, bats get a bad rep. But they are actually beneficial to the ecosystem as pest control.

Yet, they are still considered generally unlikeable animals, possibly due to their terrifying appearance. A popular Halloween animal, bats are hideous creatures with scary fangs and sharp wings.

Unfortunately, they are known carriers of rabies, the single most deadly virus in the world. Even if less than 1% of the population carries it, getting bit by a bat almost always means you need to get a rabies shot. 

On a lighter note, despite the popular myth, bats aren’t the bloodthirsty animals we think they are – choosing rather eat insects than drink human blood.

An adorable little rodent – the rat is also a widely hated animal. Most of us see rats as dirty, filthy creatures that carry diseases. 

You’re probably familiar with the Black Death, a plague pandemic that killed nearly ⅓ of Europe’s population in the 14th century. Most people believe that rats were responsible for the spread of this deadly disease. 

Nevertheless, recent studies proved that wasn’t the case – confirming that these critters aren’t as bad as they seem.

In fact, rats are very intelligent, and they make wonderful pets. They are also clean animals who groom themselves more often than cats! In other words, they probably don’t deserve the hate they receive. 


wasp on a green leaf

Unlike bees, which are beloved and valued species on the planet, humans are hateful toward wasps. These insects are not something you’d like to see on your picnic. 

Wasp stings are painful and irritating, and if you’re allergic may even lead to death. Interestingly, 3% of the world’s population is allergic to insect stings. 

On top of that, wasps are annoying to deal with in general. They will infest your food and drinks, buzz in your ear, and likely require you to move to get away from them. 

Nevertheless, these insects are also essential to the ecosystem.

Similarly to spiders, snakes are one of the most feared and, in turn, most hated animals in the world. The fear of snakes, called ophidiophobia, is one of the most common phobias. 

It’s speculated that we’re hardwired to be afraid of snakes as an evolutionary advantage. If we’re scared of dangerous animals, we’re more likely to avoid them, which increases our chances of survival. 

Furthermore, snakes aren’t as likely to attack humans as you may think – most species would rather run away than engage. 

Nonetheless, if you live in an area inhabited by venomous snakes, stay away. Like most other animals, a snake will attack if it feels threatened – your best bet is to avoid any snake you see in the wild. 


cockroach on a rock

Not only are cockroaches annoying to deal with, but they can also pose a threat to your health. Consequently, it’s apparent why these pests are so hated in the community.

We tend to associate these creatures with filth. They are drawn to food and can leave droppings and dead skin over it, unnoticeable to the naked eye. If you ingest it, you can get food poisoning from the bacteria they carry. 

Unfortunately, they can also crawl into your ear or nose when you sleep. Yuck!

But most importantly, they are challenging to deal with. If you have a roach infestation, getting rid of them is quite a headache, as they are very resilient little monsters.

The last member on our list of most hated animals is the raccoon. This adorable mammal may seem cute from a distance. Still, unfortunately – raccoons are considered pests in some areas.

They damage crops and gardens and will also raid your garbage, making noise and creating a big mess along the way!

As nocturnal animals, they look for food and shelter during the night. Whether you’re woken up by a sound of a raccoon causing ruckus, or you wake up in the morning to find your entire yard destroyed. 

It’s easy to see why these cute creatures aren’t well-loved. 

In Summary

This brings to a close our list of the most hated animals in the world. And while most of us have our own reasons for disliking some (most) of these creatures, they act in a way that makes perfect sense to them even though it doesn’t to us. 

Thank you for reading. Hopefully, you’ve gained some insight into their behavior and learned that not all animals deserve the hate they get!
