Indoor and outdoor resting mosquito recapture
Mosquitoes that were not caught in the bed net trap or window exit trap were collected from inside the hut and outside at 0700HRS using Prokopack aspirators (John W Hock, Gainesville, FL, USA). For mosquitoes resting indoors, walls and ceilings were systematically aspirated using progressive down and upward movements along its entire length. For outdoor resting mosquitoes, the collection was done from the clay pots (Fig. 1 F) by placing a white mesh from a mosquito cage over the mouth and agitating the mosquitoes inside the pot, causing them to fly and move to the cage (van den Bijllaardtet al. , 2009). The corners of the screen house and the vegetation cover were also scanned for resting mosquitoes using the Prokopack aspirator.
