The walls, ceilings, roof, clothing, furniture, including the underside of
beds, and other objects in huts should be examined with a torch to locate
resting mosquitoes. In some areas where houses are raised on stilts
mosquitoes may also rest underneath them (Spencer 1965). In Tanzania
Smith (1955) found that in both round and rectangular village huts about
62–66% of the females and 60–70% of the males of Anopheles gambiae
rested below the thatched roof, mainly on the mud walls, but also on
various objects and under the beds. Similarly, in later studies Smith
(1962a,b) found that about 56–75% of Anopheles gambiaerested on hut
walls and household objects.
