Mean (±s.e.) number of An. gambiae mosquitoes captured outside or inside experimental houses per night, depending on house type (Experiment 1). There were three house typologies: a standard village style house with closed eaves but no EaveTubes or screening; houses fitted with EaveTubes alone and no screening; houses fitted with screening + EaveTubes. In addition, householder behaviour was managed to either reflect typical behaviour in which doors and windows were open for part of the evening and morning (see Methods and figure 3), or behaviour was modified so that doors and windows were kept closed from 18.00 to 8.00. Mosquitoes were collected by HLC from 18.00 to 8.00. The means represent 48 nights of capture with individual treatments replicated 24 times.
