Mosquitoes

Weighted mean
indoor biting rates by the proportion of children <5 years reporting to be asleep |
Weighted
mean outdoor biting rates by the proportion of children <5 years not yet asleep |

Assuming sleeping time = time indoor (this gives the lower bound fraction human exposure that can be reduced by LLINs)
