Let us start out with one of the most annoying and notorious insects in the world – the mosquito. However, what is not so well-known about this little bloodsucking pest is the fact that it actually is also the world’s deadliest animal, being responsible for an estimated 725,000 human deaths each year through the transmission of various diseases.


Flesh Fly

The Flesh Fly is similar in appearance to the common house fly; it is characterized by blackish stripes on the gray thorax and a checkered pattern of light and dark gray on the abdomen. Most Flesh Flies are tropical, but the family is generally widespread. They differ from most flies in that they opportunistically deposit hatched or hatching maggots on carrion, dung, decaying material or open wounds of mammals.



Cockroach Source: pestworld.org

One of the most feared and infamous insects, Cockroaches have been long despised by homeowners due to their creepy appearance. Cockroach pest control and management are important for health and safety reasons; these large and extremely hardy bugs are known to cause allergic reactions and even trigger asthma attacks. They also spread over 30 kinds of bacteria including E. coli and Salmonella.



EarwigSource: orkin.com

Armed with a pair of forceps-like pincers on their abdomen, Earwigs are often considered one of the most annoying bugs outside. There are many myths associated with these nocturnal creatures. For instance, the (false) urban legend that says the Earwig can burrow into a man’s brain through his ear. However, the Earwig is usually harmless to humans, and it only uses the pincers for defense.



CicadaSource: nationalgeographic.com

Close relatives to leafhoppers and froghoppers, Cicadas are probably best known for their annoying buzzing and clicking noises, which can be amplified by multitudes of insects into an overpowering hum. Males produce this species-specific noise with vibrating membranes on their abdomens. There are about 3,000 different species of this insect family.
