In the distant past insects such as mosquitoes, flies and fleas were a particularly common problem. Rodents, such as rats, were important vectors for disease.
Pest control and disease management are integral components of maintaining a healthy and sustainable environment, particularly in agriculture and public health. Pest control refers to the regulation or elimination of harmful organisms that can negatively impact crops, livestock, or human well-being. These pests, which include insects, rodents, and pathogens, can lead to the spread of diseases among plants, animals, and humans. Effective pest control strategies involve the use of various methods such as chemical pesticides, biological control agents, and cultural practices to minimize the damage caused by pests.
Moreover, the connection between pest control and disease is evident in the agricultural sector, where pests not only harm crops directly but also serve as vectors for plant diseases. In public health, the control of disease vectors, such as mosquitoes and rodents, is crucial to preventing the transmission of illnesses like malaria, dengue fever, and leptospirosis. Integrated pest management (IPM) approaches, which combine multiple strategies for sustainable and environmentally friendly pest control, have gained prominence in recent years.
Vector-borne diseases such as mosquito-borne malaria were common. Plague, transmitted from fleas to rodents, caused devastating epidemics.
Globalization has led to the introduction of invasive species, spreading pests to new regions. Bed bugs are a common problem in urban areas. Mosquitoes, ticks, fleas, and flies, can spread diseases such as malaria, yellow fever, Zika, dengue, West Nile virus, chikungunya, and Lyme Disease. While some cases are mild, these diseases can be severe and have lasting consequences.
Cockroaches, ants, spiders, and rodents remain persistent pests. House flies are suspected of transmitting at least 65 diseases to humans. Typhoid fever, dysentery, cholera, poliomyelitis, yaws, anthrax, tularemia, leprosy, and tuberculosis may be contracted through contamination from flies. Flies regurgitate and excrete wherever they come to rest and can transmit disease to humans this way.
Mice and rats can carry harmful diseases, such as Leptospirosis, lymphocytic choriomeningitis, plague, Hantavirus pulmonary syndrome, and typhus. Hantavirus is spread to people from mice and rats. The virus, is found in rodent urine, saliva, and feces. It can be easily released in the air when disturbed by simple human activities, such as sweeping or vacuuming.
Global travel and climate change are making emerging diseases, including Zika, dengue and chikungunya, more prevalent.
Allergies and respiratory problems associated with household pests such as dust mites and cockroaches are becoming more widely recognized.
