Found in association with humans and their activities all over the world, the House Fly is one of the most common and annoying insect species in the world. Not only are these insects a nuisance, but they can also transport disease-causing organisms. Excessive fly populations are problems to farm workers, and they can also pose a serious public health problem. House Flies also carry pathogens on their bodies and in their feces and can contaminate food.

Technically, the Tick is not an insect but an arachnid; however, these tiny blood-sucking pests are among the most annoying creatures out there, so we decided to include them in this list. The Tick’s mouth is so small that the host usually doesn’t feel the bite and is often unaware that they have been bitten. Ticks are also capable of spreading various diseases to humans through their saliva.


Clothing Moth

There are about 160,000 species of the Moth, but few of them have as bad of a reputation as the Clothing Moth, a small insect notorious for eating our clothes. However, it is not the Moth itself that eats the clothes but the larvae. The larvae have a fairly specific diet, and so female moths typically deposit the eggs into clothes made from animal fibers such as silk, wool, cashmere, angora, or fur.


Yellow Jacket

Named after its yellow-black body, the Yellow Jacket is a common name for a predatory wasp. The Yellow Jackets are known to fiercely defend their colonies, and they are capable of delivering multiple, painful stings. The stings may also induce severe allergic reactions in some individuals, which can occasionally even result in death.



FleaSource: britannica.com

Usually reaching just up to 3 mm (0.12 in) in length, the Flea is a small flightless, parasitic insect that lives by consuming the blood of its mammal hosts. One of the animal kingdom’s greatest jumpers, Fleas can also transmit dangerous diseases. As the chief agent transmitting the Black Death (bubonic plague) in the Middle Ages, they were an essential link in the chain of events that resulted in the death of a quarter of the population of Europe back then.
