Proportional retention of the pyrethroid and non-pyrethroid components in washed and field-aged PermaNet® 3.0 (roof) (a), Royal Guard® (b) and Interceptor® G2 (c). Retention was calculated relative to the mean active ingredient content with new unwashed nets. Brackets between bars indicate pairwise comparisons between groups, with p-values representing the statistical significance. P-values < 0.05 were considered significant. Error bars represent 95% confidence intervals
