Trying to choose three insects that spread disease is not difficult. The hardest part is choosing those three out of a very long list of pests that cause incredibly powerful diseases.


Ticks can cause many diseases, but perhaps the most widely distributed disease caused by ticks is Lyme Disease. Lyme disease causes inflammation and can affect your immune system. In the beginning you suffer from fever, chills, and headache and as the disease progresses it causes arthritic type problems with joins then moves into neurological symptoms and finally, cardiac disorders can appear. There is no cure for Lyme Disease.


Mosquitoes are high on the list of insects that spread disease. Around Texas, mosquitoes can spread West Nile Virus, which can be deadly. There is no vaccine or cure for West Nile Virus. Symptoms begin with those that mimic the flu. As the disease progresses serious issues can present, including encephalitis. Outside of Texas, malaria is a disease that is spread by mosquitoes. Yellow fever is another.


Two diseases that fleas transmit to humans are typhus and bubonic plague. Historically, Typhus is what killed off Napoleon’s army. Bubonic plague is what killed so many people during the Middle Ages. Plague still occurs in modern times and so does typhus. Both are controlled with medications and good hygiene.

The sad truth is that many diseases are spread by pests. As a group, flies are probably the most notorious group of insects that spread disease. There are also some unassuming insects that spread disease too – such as the kissing bug.
