Welcome to Defon

Welcome to the world of Defon Pest Management & Hygiene, where almost five decades of expertise, unparalleled customer service, high-tech products and a pledge to the environment converge to improve the quality of life. Defon is recognized globally as an expert in pest management and hygiene, offering a variety of services and products across sectors.

Defon's success began with the shipping industry, giving it the competitive advantage of working with the most demanding sector around the world. This success has been replicated in commercial and residential environments, while fully embracing a philosophy that is both eco-friendly and customer oriented.

World Presence

Defon Pest Management & Hygiene is known worldwide for setting up a task force in virtually any city or port on demand and as long as required, a concept that has become the backbone of the company's global responsiveness and efficiency.

Demand for Defon's services from the shipping industry drives the company to open satellite offices in various locations around the globe for the duration of its contracts.

For instance, Defon operated an office in Rotterdam for 26 years and in Genoa for 10 years until its clients moved their base of operations to other ports, where Defon was there to greet them on arrival. In Jeddah, Defon serviced the fleet of famed Greek ship-owner Latsis for many years and still works with his company in other locations. Tokyo also saw the opening of a Defon office as it catered for important shipping firms.

Current work has been conducted in Australia, Bahrain, Egypt, France, Gibraltar, Italy, Japan, the Netherlands, Saudi Arabia, Spain and the UK, among others.


Founded in 1961 by Sotirios Apostolou, Defon began its operations by offering disinfestation, disinfection and rodent control to the shipping industry.

A growing world of services...

Over the years, Defon's consistently high standards in the shipping sector have lead to an increase in demand from a large variety of other businesses. Gradually, Defon's services evolved into Integrated Pest Management (IPM) and Hygiene, while its customer base grew impressively. The company extended its services to the following:

  • healthcare facilities (hospitals, clinics)
  • hospitality businesses (catering, hotels, bars, restaurants, etc.)
  • industrial (warehouses and factories)
  • municipal (schools, nursing homes, sports centers, government offices, public spaces)
  • offices (media headquarters, banks, embassies, etc.)

Demonstrating its continuous evolution, Defon Pest Management & Hygiene expanded globally after having penetrated all sectors in the domestic market.
