If you don’t mind a bit of guppy poo in your water, this is a good solution, as long as the guppies are indigenous… “This is a low-cost, year-round, safe way of reducing the spread of dengue in which the whole community can participate,” Gerard Servais, a health specialist with ADB, said. “It offers a viable alternative to using chemicals and can reduce the scale of costly emergency response activities to contain epidemics.”

The study found that guppies do not harm water quality and can survive on microscopic organic material in the absence of mosquito larvae. When the project closed in Cambodia, approximately 88 percent of the storage containers contained guppies. There were guppies in 76 percent of the containers in Lao PDR at the project’s close.

“The project was successful in mobilizing communities with widespread grassroots participation, and high levels of acceptance of fish as an effective way of reducing the spread of dengue,” Eva Christophel, a vector-borne diseases specialist with the WHO, said. “This project was an important contribution to WHO’s efforts to develop a toolkit of different community-based methods to prevent and reduce the magnitude of dengue transmission.”
