Impact of pre-season TIRS on Ae. aegypti density. Estimated mean (± 95%CI) number of Ae. aegypti adults per house at baseline (April) and 1–8 months (July 2019-January 2020) post-TIRS application of two long-lasting residual insecticide formulations in Merida, Mexico. TIRS was conducted in June (dashed vertical line), prior to the regular arbovirus transmission season. Top panel shows the standardized incidence of dengue from 1991–2001 in Yucatan, with values closer to 1 indicating periods of high transmission and values closer to 0 of low transmission.
