Top Ten Deadliest Insects

Fleas are the external parasites in humans and other mammals and birds, belonging to the order of Siphonaptera insects. These insects are wingless usually dark in color such as reddish brown color of cat flea.

Fire ant is the common name for several species of ants in the genus Solenopsis. They are, however, only a minority in the genus, which includes over 200 species of Solenopsis worldwide. Solenopsis are stinging ants and most of their common names reflect this, for example, ginger ants and tropical fire ants.

Chagas disease is spread by the triatomine bug -- nicknamed "kissing bugs" -- which carries the parasite Trypanosoma cruzi. Over time, the parasite can chew through cardiac muscle and cause heart failure causing an estimated 11,000 deaths globally each year.

The Japanese giant hornet (Vespa mandarinia japonica) is a subspecies of the world's largest hornet, the Asian giant hornet (V. mandarinia). It is a large insect, with adults frequently growing to greater than 4.5 centimetres (1.8 in) long, with a wingspan greater than 6 centimetres (2.4 in).

Deadliest Insects in the World It is not irrational to be afraid of insects, because some insect species are actually among the deadliest animals on earth. Strangely enough, many of the deadliest insects are not the ones we are most afraid of.

Although not technically fitting into the bug category, black-spitting thick tailed scorpions are among the most dangerous species of scorpions. Most of them live in South Africa, especially in deserts.

The Africanized bee is widely feared by the public, a reaction that has been amplified by sensationalist movies (such as The Swarm) and some of the media reports. Stings from Africanized bees kill on average one or two people per year.

5. Fire Ants. Typically nesting in sand or soil, fire ants build rather large mounds and tend to feed on plant life and occasionally crickets and smaller insects. When bothered, however, the fire ant sting is a venomous prick that feels like it’s burning with fire, hence the name and swells up into a painful pustule.

Which is the deadliest insect on Earth? You may be thinking of killer bees or maybe African ants or Japanese hornets. While all of these are certainly dangerous insects, the deadliest is none other than the mosquito. Mosquitoes alone can't do us much harm, but as disease carriers, these insects are downright lethal.

It lists pain on a scale from one to four and unsurprisingly the bullet ant tops the charts. Level 4: bullet ant, tarantula hawk wasp; Level 3: paper wasp, harvester ant; Level 2: honey bee, yellow jacket wasp, bald-faced hornet; Level 1.5: bullhorn acacia ant; Level 1: fire ant, sweat bee “Level four you don’t want to know,” explains Dr Schmidt.

But there are many insects which have expertise in torturing us. One of these types of insects is the Botfly. This Botfly does not possess any venom, as far as I know them. But still they are one of the deadliest insects of the world, maybe not for other animals, but for us, the humans, botfly is really one of the most deadly animals.
