25 Most Dangerous Bugs In The World

Posted by on July 15, 2013

The millions of species of bugs that exist in the world today play a pivotal role in our ecosystem. Though a majority of them are harmless, some are especially good at either transmitting disease, injecting venom, or just generally being a nuisance. From bullet ants to tse tse flies these are the 25 most dangerous bugs in the world.




While they are not dangerous in the typical sense of the word as they play a critical role in the environment and even in some culture’s diets, they have the potential to cause major damage to crops and infrastructure.




Lice are wingless scavengers that feed on the skin of the host’s body, or on other secretions such as blood. On the average, humans who serve as hosts to lice have about fifteen different species of lice on their heads. Although like termites they are not always dangerous to humans in the classic sense they do have the ability to transmit diseases.


Deer Tick

Every year the Deer Tick infects thousands of people with Lyme Disease. Lyme Disease begins with a rash around the bite resembling a bull’s eye. Early symptoms include head ache and fever. As time passes, the victim will suffer stiff joints and heart problems. Few victims die from the disease but their suffering can go on for years.


Army Ants


The first creature on our list that would be dangerous in the typical sense of the word, army ants are known for their aggression, especially as predators. Unlike other species of ants, army ants do not construct their own permanent nests. Instead, they build colonies that move from one place to another. These predators incessantly move during the day, preying upon insects and other small vertebrates. In fact the entire colony put together can consume over  half a million prey animals each day.


Yellow Jackets


Although most yellow jackets are little more than a pest, certain species such as the German yellow jacket of North America are bold and aggressive, and if provoked, they can sting repeatedly and painfully. They will even mark their aggressors and pursue them if provoked.
