The company hired to carry out pest control at last year’s Olympic and Paralympic Games in Rio de Janeiro has revealed how they kept the event free of the Zika virus.

The virus, which is carried by mosquitoes and has been linked with microcephaly, a condition in which babies are born with small heads and underdeveloped brains, remains a concern in parts of the Americas.

It was one of the main fears leading up to Rio 2016, with a host of top male golfers and tennis players opting to withdraw from the Games as a result, despite insistence from organisers and local officials that it would not be a problem.

The World Health Organization (WHO) confirmed after the conclusion of the Olympics that there were no cases of Zika recorded among anyone associated with the Games.

Rentokil, who began their role in May 2016, have now spoken publicly for the first time about the methods they employed to tackle the virus.

The British-based company, established in 1925, said they used a new non-chemical treatment of ultrasonic pulses to destroy mosquito larvae in open water, according to The Telegraph.

It is claimed this helped reduce the amount of larvae by 90 per cent.

Rentokil also used a programme which utilised specially-placed traps to warn of the presence of mosquitoes.

Preventative pest control measures and traditional insecticide was used at venues across the Games, including the Athletes’ Village and the main Media Villages.
