Abstract

Donath S Tarimo* and Remigi Cosmas

Olyset® nets are effective for malaria control; approved as best choice for rural areas. It is unclear to what extent insecticide persists in the use period. Washing frequency under different methods, soap and drying methods may conceivably lead to a change over time in insecticide concentration. This study examined net ownership, types, handling; and changes in permethrin concentration in Olyset® nets over time.
