Comparison of surface residual and average household concentrations concentration between March and June. The average household concentration from six surfaces is presented for the March and June IRS operations with respect to the recommended dose of 0.5 g/m2 and a dose with no added insecticidal benefit of 1.5 g/m2. Those within the appropriate range are shown in grey, those either too high or low are shown in red. The average surface concentration applied by spray operators is presented for the March and June IRS operations with respect to the recommended dose of 0.5 g/m2 and a dose with no added insecticidal benefit of 1.5 g/m2. Those within the appropriate range are shown in grey, those either too high or low are shown in blue and red, respectively
