'We spray and walk away': wall modifications decrease the
                impact of indoor residual spray campaigns through reductions in
                post-spray coverage

Malaria prevalence has significantly reduced since 2000,
                largely due to the scale-up of vector control interventions,
                mainly indoor residual spraying (IRS) and long-lasting
                insecticide-treated nets (LLINs). Given their success, these
                tools remain the frontline interventions in the fight against
                malaria. Their effectiveness relies on three key ingredients:
                the intervention, the mosquito vector and the end-user.
                Regarding the intervention, factors such as the insecticide
                active ingredient(s) used and the durability and/or bio-efficacy
                of the tool over time are critical. For the vectors, these
                factors include biting and resting behaviours and the
                susceptibility to insecticides. Finally, the end-users need to
                accept and properly use the intervention. Whilst human attitude
                and behaviour towards LLINs are well-documented both during and
                after distribution, only initial coverage is monitored for IRS
                and in a few geographic settings the residual efficacy of the
                used product. Here, the historical evidence on end-users
                modifying their wall surfaces post-spraying is presented, a
                behaviour that has the potential to reduce actual IRS coverage,
                effectiveness and impact, as fewer people are truly protected.
                Therefore, clear guidelines on how to monitor IRS acceptability
                and/or coverage, both before, during and after spraying, are
                urgently needed as part of the Monitoring and Evaluation of
                malaria programmes.
