Human landing catch (HLC) is the standard sampling method for collecting human-biting blackflies, however, there are ethical concerns regarding exposure of vector collectors to infective flies. Despite this limitation, its use continues as no method has been found suitable to replace it. Entomological evaluations requiring large fly catches are critical for stopping mass drug administration (MDA) and verification of onchocerciasis elimination. With many countries entering elimination phase, alternative methods should be found. This study will evaluate a modified HLC where vector collectors will be protected by coloured-socks attractive to blackflies allowing them to land on the human but preventing biting.
