Top 10 Extremely Dangerous Insects in the world

10. Hemiptera – kissing bugs

Hemiptera - kissing bugs
The bugs from hemiptera classification have distinct ‘sucking’ mouth parts and resemble tubes. Majority of them feed on plant sap in one or the other form. But few of them are exception and feed on the blood of larger animals. The bugs are known to transmit Chagas Disease. The symptoms change over the course of infection. In the early acute stage the symptom are mild and displays no more than local swelling at infection site. The disease stays for over twenty years and as the disease progresses more serious symptoms appear such as heart disease. The symptom also includes malfunction of intestine. . If the disease is not treated, the chronic disease could be fatal. The present drug treatment is unsatisfactory since they are highly toxic and ineffective, especially in the chronic stage.

9. Giant Japanese or Asian Hornet

Giant Japanese or Asian Hornet
This hornet can grow in length up to 3 inches. It is well know that only 20 to 30 of them can decimate an entire hive of honeybees. The sting can be lethal, not only in terms of allergic reactions, but also because they carry many toxins. The sting of this hornet has got highest concentration of Acetylcholine, a pain-causing chemical compared to the sting of any other insect. Enzyme present in their venom can dissolve human tissues. The sting contains at least eight distinct chemicals; interestingly their venom attracts others of its kinds to the victim. These hornets can sting repeatedly.

8. Siafu (African Ants)Dorylus

Siafu - African Ants - Dorylus
Everyone knows that ants are industrious, yet these Siafu ants are special. Their single colony of 20 million ants can easily ravage African countryside, literally destroying anything that comes their way. When there is a food shortage, the whole colony marches out, be whatever comes their way, to acquire food. These ants can easily be avoided, yet each year 20 to 50 people die. Most of the times very young and elderly find themselves as the victims of asphyxiation. They are also behind damage worth thousands of dollars of food each year.

7. Wasps

Wasps
They are mostly not one of the extremely dangerous insects. These wasps in their yellow jackets with hornets are relatively social and generally terrestrial. They will generally their own parasite or pest that they prey upon exclusively. They do not intensively lookout of humans to sting. However if their territories are being threatened they will not refrain themselves from stinging. Their stings are oft-allergic and cause most damage. It results in anaphylactic shock and the victim may even die as a result of a single wasp sting.

6. Locusts

Locusts
You must be thing what a locust is doing in this list. They are not by any chance known for killing humans at least directly. Yet still their strength lies in their number that that is the threat they pose each year. Locust can strip bare earth in thousands of acres of crop land every year in a very short time since each swarm consist of several thousands of insects and they can contribute to death by starvation.

5. Fire Ants

At the 5th position of extremely dangerous insects we have Fire ants that build large mounds and feed on plant leaves. They occasionally feed on crickets and small insects. But is they are bothered, they don’t hesitate to sting. The sting of fire ants is venomous prick and it feels like burning with fire. This is how they have got their name as Fire Ants. Few small stings can easily and quickly treated and cured. However when the swarm of ants attacks, it could be the beginning of the real trouble. Each year 150 deaths are reported and millions of dollars are lost due to crop damage making these ants fearsome.

4. TseTse

TseTse
This insect is the carrier of the deadly sleeping sickness. It feeds on the blood of vertebrates and this is how it spreads trypanosomiases disease in humans. The death toll in Africa is alarming because of their biting. Every year 250 to 300 thousands victims are reported each year.

3. Honey Bees

Honey Bees
Their numbers have increased over the years. They actually pose no threat to humans since they have no intent to do so. More so ever even if they sting, they die after the deed is done. Many people world over are allergic towards their sting. And many of them experience death due to anaphylactic shock. However unlike standard bees, these bees attack victims in swarm with slightest provocation. Each the death toll is reported in thousands.

2. Fleas

Fleas
Fleas are dangerous are directly responsible for spreading Plague that they receive from their host rats. Hence their bits are not one of those annoying little bits, but indeed are serious. Fleas contribute to the spread of Bubonic Plague. They receive it from their host rats and pass it over to humans carrying Yersinia Pestsis. Fleas feed on the blood of warm-blooded vertebrates and can easily infest animal and humans. If bitten the wound swells and leads to allergic reaction.

1. Anopheles Mosquito

Anopheles Mosquito
At the first position of extremely dangerous insects we have Anopheles Mosquitoes which are one of those a terrible irritant and feed on blood. The mosquitoes lay their eggs in stagnant and unattended water sources. Millions of mosquitoes can hatch from just a single source. However the real threat the mosquitoes pose are the blood-borne diseases that they carry. Most dangerous notorious of all is the Malaria. Every year hundreds and millions of people die because of malaria. In fact the death caused by malaria will outnumber all of the death caused by putting all of the insects together.
