Washing: Proportion ever washed, mean washes and wash frequency. a: Proportion of nets ever washed (filled circles) and mean number of washes (open circles) for phase one (line) and phase two (dashed). Error bars represent 95% confidence intervals. The dotted line (open circles) shows the mean number of washes for phase 2 nets when aligned in time since start of study rather than time of observation. b: Mean monthly washes between surveys for phase one (line) and phase 2 (dotted). Error bars represent 95% confidence intervals.
