Table 1 Summary of findings in tests for effects of traps alone (pull only), spatial repellents alone (push only) or combinations of traps and spatial repellents (push–pull) on the biting risk of Anopheles arabiensis indoors and outdoors
Intervention | N | Indoor biting risk (assessed using CDC-light trap) | Outdoor biting risk (assessed using human landing catch) | Mosquitoes trapped | ||||||
|---|---|---|---|---|---|---|---|---|---|---|
