Pest Control Expert
John Charlton has been Technical Director of Rentokil since 1987. As one of the UK's leading pest control experts and an authority on the problems that pests can cause he's constantly surprised by how lightly some businesses still take the risks.
What got you interested in pest control in the first place?
I replied to an advertisement for a position in the Chemistry department of the Department of Agriculture and Fisheries for Scotland in Edinburgh. The interview board enquired if I would consider an interview for an alternative position in the Rodent Control department working on warfarin resistance. I was offered and accepted this position. Apart from rodents, the work included investigations into the management of American mink, foxes, hooded crows, starlings and geese.
What was your first job in Rentokil and when did you start?
My first job in Rentokil was as Serviceman (Technician) in 1970.
How long have you been Technical Director?
I took over the role of Field Technical Manager in 1987 following the retirement of John Bull. The job title has evolved since then through Technical Manager to Technical Director in 2004.
What's the most enjoyable part of your job…?
The variety. Working with a team of experienced, knowledgeable and resourceful colleagues and, through this, involvement with a wide range of industry professionals.
…and what's the biggest challenge?
Developing techniques and products to replace those no longer available, due in the main to increased regulatory restrictions, while control of certain pests in some situations is becoming more difficult.
What do you see as the biggest challenge for the pest control industry in the next 5 years?
The potential impact that the activities of the pest control industry have on the environment will continue to be one of the major issues we will need to address. Techniques, products and training to reduce as far as possible the risk to non-target species, particularly through secondary poisoning, and a greater awareness of the importance of biodiversity will be essential in the future. The greatest challenge will be to introduce these measures in a business environment where customers are asked for, and are increasingly demanding, pest-free conditions on their sites.
I understand you are interested in British Wildlife. Can you bring any of that interest into your job?
Knowledge of the biology, habits, signs of and evidence left by animals, whether insects or vertebrates, is essential if we are to understand how they can be controlled. This is also the case if we are to avoid causing damage to the environment and non-target species. Many in the pest control industry have a wider interest in natural history either through field sports or membership of one or more of the natural history organisations.
Your department undertakes many roles including training and quality control. What is the biggest job they face in the next year or so?
Rentokil Pest Control has introduced several new systems designed to ensure our customers receive the best service possible. Our priority is the spread of good practice through the development of the individual. We must capitalise on the wealth of experience among our Technicians, Supervisors, Service Managers and Field Biologists by allowing them the opportunity to pass on their skills to others. We are very fortunate to have the people — we have to develop them.
