Repeated spraying with pyrethroids of persistent sites of infestation demonstrated that some bug populations could not be eliminated even after 4 professional treatments. By identifying and mapping households and spatial clusters at higher risk of transmission, targeted strategies involving close monitoring of infestation may be more cost-effective in disperse rural areas than blanket vector surveillance strategies. Transmission was more intense in domestic sites, followed by storerooms or kitchens.
