Malaria is a leading cause of death in the developing world. There are 200-300 million cases of acute malaria each year, resulting in approximately 1 million deaths. Poverty and malaria are interconnected; malaria disproportionately affects poor people who cannot afford treatment or have limited access to health care, and traps families and communities in a spiral of poverty.

Insecticide-treated bednets and Indoor Residual Spraying are the primary interventions used in malaria control, yet there are challenges with household uptake, retention and compliance.  There remains a need for the development of new, effective products to aid in the fight against malaria.





In 2009, Acumen Fund, Richard Allen and Vestergaard-Frandsen created Durable Activated Residual Textiles (DART), a joint venture company to develop new and innovative products to combat malaria.  DART has developed insecticide treated wall-lining to complement and eventually replace Indoor Residual Spraying.

Unlike Indoor Residual Spraying which must be repeated every 6-12 months, DART’s wall lining will afford protection to all members of a household for a minimum of three years.  The lining also protects against diseases like Dengue Fever, and controls nuisance pests such as ants, cockroaches and bedbugs.

The lining can be applied in rural settings with minimal supervision, and is printed in different colors and patterns to be aesthetically desirable.




DART has conducted field trials in over 10 countries in sub-Saharan Africa and Latin America and is currently in talks with the WHO over Phase III testing.
