Less is more: repellent-treated fabric strips as a substitute for full screening of open eave gaps for indoor and outdoor protection from malaria mosquito bites

Table 1 Summary of experimental procedures implemented as blocks of two test treatments in parallel in two semi-field systems

Experimental blocks	Location of human landing catches	Treatment in semi-field system A*	Treatment in semi-field system B*
1	Indoors	Open eave	Untreated eave strip
2	Indoors	Untreated complete eave screen	Transfluthrin-treated complete eave screen
3	Indoors	Transfluthrin-treated complete eave screen	Transfluthrin-treated eave strip
4	Outdoors	Open eave	Untreated eave strip
5	Outdoors	Untreated complete eave screen	Transfluthrin-treated complete eave screen
6	Outdoors	Transfluthrin-treated complete eave screen	Transfluthrin-treated eave strip

Indoor and outdoor human landing catches were done in independent experiments. Each block of experiments was implemented over 16 nights
*All treatments were switched between semi-field systems every 4 days, ensuring that in each experimental block the treatments were equally applied in system A and B
