Mosquito density in houses estimated using pyrethrum spray catch in Doneguebougou and Banambani (pooled) over time showing variation among houses. In box-whisker plot, the box extends between the 25th and the 75th percentile, i.e., across one inter quartile range (IQR), and the whiskers extend up to the most extreme value, but not beyond 1.5 times the IQR. Outlier values located 1.5–3 IQR from the median are shown as “○” and extreme outliers located over 3 IQR are shown as ‘*’
