  1. ID and PD: number of evaluated and infested houses in intradomestic and peridomestic structures. BL is the entomological evaluation of houses before the microencapsulated application (baseline); E1, E2 and E3 are entomological evaluations after 2, 12 and 32 months after the microencapsulated application. Odds ratio (OR) and 95% confidence interval (CI95%) contrasts infestation prevalence at BL, with entomological evaluations after the microencapsulated application (E1, E2, E3).
