Table 1. Relationship between infestation and the proximity of street lights.

	Close to a street light (<17 m)	Far from a street light (>17 m)
Infested houses	111 (51.9%)	103 (48.1%)
Non-infested houses	581 (39.6%)	885 (60.4%)

The proximity of a public street light resulted in a 1.64 fold increase in the likelihood of a house being infested (95% confidence interval: 1.23–2.18).
