About the profession

Rodent control, disinfection and insect control (DDD) are procedures that safeguard public health by controlling and eliminating pests, primarily rodents, insects and microorganisms. 

These practices date back to ancient times, when people intuitively recognised the dangers posed by pests and microorganisms and tried to limit their impact on health and daily life.

In ancient Egypt, various substances such as ash and herbs were used to repel insects, while the Romans developed more sophisticated methods, including sewer systems and baths, which significantly reduced the spread of disease.

The Middle Ages were marked by numerous epidemics, including plague, which was spread by rats. These periods led to the development of the first basic rodent control practices as people recognised the link between rats and disease. In the 18th and 19th centuries, advances in science and medicine brought major developments in disinfection, particularly following the discovery of microbes and the theory of disease transmission.

Chemical insecticides and rodenticides came into use in the early 20th century, enabling more effective insect and rodent control. DDT was particularly significant and had a major impact on insect control, although it later became controversial because of its effects on the environment and human health.

Today, DDD services involve environmentally acceptable methods, integrated pest management (IPM) and science-based preventive approaches, reducing risks to people and the environment. The profession is increasingly focused on sustainable and environmentally friendly methods, with an emphasis on prevention and public education.
