4 of the Deadliest Insects in the World


Every creature in the world plays an important role in balancing the ecosystem. However, despite their significance, some insects are perceived as pests because of their harmful effects to both humans and the environment. There are many types of insects – such as ants, cockroaches, fruit flies, and termites – that can damage your house and spread various diseases. One of the best means of avoiding and preventing them from invading your home is by seeking the help of various professional pest control companies. Familiarizing yourself with the various pests that may invade your home is also very beneficial. To do this, check some of the deadliest insects below and the reasons why you should avoid them.

Anopheles Mosquito

Mosquitoes are some of the most terrible and annoying pests in the world. This insect feeds on human blood and can spread various diseases. One of the deadly types of mosquitoes is the anopheles mosquito. It is known for transmitting blood-borne diseases like malaria – a disease that is responsible for more than one million deaths every year. A German entomologist, Johann Wilhelm Meigen was the first person to describe the genus anopheles.


TseTse Fly

Found in Africa, tsetse fly is a large biting fly that tends to feed on the blood of a vertebrate. It resembles a house fly; as a matter of fact, both insects’ size ranges from 8 to 17 mm. This insect is a carrier of trypanosomiasis or sleeping sickness. Like an anopheles mosquito, the tsetse fly bites humans, transferring the disease to its victim. Sleeping sickness is characterized by fever, headache, and joint pain.

Giant Japanese Hornet

The giant Japanese hornet or Asian hornet is one of the most dangerous insects in the world. It only takes 20 to 30 of this type of wasp to annihilate a hive of honeybees! Aside from posing a threat to other insects, Asian hornets are also dangerous to humans. After all, its sting can knock you out due to the various toxins it contains. Actually, its sting has an enzyme that is capable of disintegrating human tissue and a high concentration of Acetylocholine – a chemical that causes pain. You should definitely stay away from this insect because unlike bees, the Asian hornet can sting repeatedly.


Fire Ants

Fire ants are usually found in Asia, America, and Europe. Unlike other types of ants, fire ants build their home in large mounds of soil. Although they generally feed on plants and small insects, fire ants can still be lethal. Their venomous sting does not only leave a burning feeling, it also leads to swelling. Although a few stings are easily remedied, you won’t stand a chance if their whole colony swarms you. Every day, fire ants contribute to the destruction of crops and cause over 150 deaths.

Most insects are small, but don’t be fooled by their size; even the smallest ones can transmit fatal diseases and venom. Avoid fatal situations by staying away from the mentioned insects above.

Pest Wars: The Battle between Japanese Giant Hornets and Japanese Honey Bees

Previously we talked about the clash between termites and ants, and you’ve learned firsthand how ants almost effortlessly defeat their larger and clumsier foes in battle. They’re constantly at each other’s throats, much like how the hornets and bees in Japan are always prepared to mobilize against each other. And while ants and termites fight on land, these guys took to the skies (or at least as far above ground as they can manage).

You’d better call pest control immediately since this clash can get also pretty nasty for civilians like you and me.

Japanese Honey Bee


The Japanese giant hornets (Vespa mandarinia japonica) lust for honey; sadly, they cannot make their own. So they need to steal from those who can, namely the Japanese honey bees (Apis cerana japonica) which work for humans in numerous bee farms all over Japan. However, the bees can only produce so much honey for their employers and themselves, so they’re not very generous with anyone else. Thus, the hornets tend to take it by force.


The hornets never rush at their enemies recklessly; they’re too cunning for that. Instead they send a single hornet scout to look for a bee hive. Once one is located, the hornet leaves a trail of pheromone in and around the bee’s nest; this acts as a marker that will attract other hornets to the target.


But the bees anticipate this infiltration and act accordingly. They’d let the hornet scout inside the hive unmolested, and at the proper moment they’d converge on it in a ball of vibrating bee bodies. This trap serves to kill the scout since a hornet can only take up to 46 °C (115 °F) while the bees can tolerate up to 50 °C (122 °F). The ball can get hot enough to kill the hornet, although other bees might die in the process. They deem this a necessary sacrifice for if a single hornet escapes, they’re doomed.

If a hornet scout manages to return to its base, the hive prepares its army. A single hornet can kill up to 40 bees in a minute, and a well-organized platoon of 30 hornets can decimate more than 30,000 of their foes in just 3 hours! Smaller and less evolved, the bees can put up a courageous fight but all their efforts are in vain.


At the end of the day, the bee hive is all but destroyed. Bee heads and limbs lay on the colony floor one on top of the other while the hornets feast on the honey they left behind. Sometimes they even lick it off the bee’s corpses. And as if that’s not enough, they also prey on the bee’s larvae and some of these are taken back to the enemy’s colony to be eaten by their young. Thus they went home victorious and with their lust satisfied—for now at least!

Japanese Giant Hornet

Battles between bees and hornets can be really intense, and we can be among the civilian casualties. In Japan the hornets are known for being the second most lethal animal after humans, deadlier even than bears and venomous snakes. So better watch out for them in case they decide to have a few rounds against each other. Or better yet, call professional pest exterminators immediately at first sign of trouble!
