  1. *Human-behavior adjusted HBRs calculated as the sum of vector exposure per hour when individuals are outdoors or indoors without bednet use.
  2. **Analysis restricted to the 8 households clustered near the border to control for geographic differences.
  3. ***Rate ratios from negative binomial regression models over entire observation period, adjusted for seasonality and accounting for clustering at household level.
