The average number (± SEM) of An. gambiae s.l. (white bars) and An. funestus s.l. (grey bars; only for Buliisa) per house per night collected by light traps. In Kibaale the first two collections were done in a different site than all subsequent rounds. No collections were done in Kibaale in Aug 12 due to an Ebola outbreak. Lines indicate when nets were introduced in the entire district, with the exception of Kibaale where nets were only distributed in three sub-counties
