Mean number of An. gambiae (s.l.) females captured by indoor spray catches compared to the number of females captured with the BGS traps in the before-and-after experiment in Mali. a In 2017 BGS traps positioned outdoors with CO2 were used without heat stimulus while in 2018 a heatpad was added to improve catch rates. BGS traps captured host-seeking females of other mosquito species (see text for details). b The distance of the BGS trap from the nearest inhabited room had no effect on capture rates
