The city of Georgetown, British Guiana, with its complex system of rain water collection and storage, in the absence of a piped potable water supply, presented an extremely difficult problem in Aedes aegypti eradication. An abnormally short egg-adult cycle added to the difficulties.
The special problems encountered and the methods used to solve them are described. The spraying of the interiors of houses with DDT proved a most potent weapon in aedes eradication and was cheaper and quicker than classical anti-aedes measures.
The British Guiana Yellow Fever Control Service, during 1939–46, was financed jointly by The Rockefeller Foundation, the Government of British Guiana and from a grant under the Colonial Development and Welfare Scheme in the West Indies.
