In Colombia, the main vectors of , the causative agent of Chagas disease, are and . is present in the east region of Colombia as domestic, peridomestic, and sylvatic populations, resulting in difficulties for its control. A cost-effective way to prioritize houses for treatment is to stratify houses based on risk factors. In this study, risk factors were evaluated for potential associations with domicile infestation of . There was an increased likelihood of domestic infestation associated with the presence of mixed roofs (odds ratio [OR] = 36.14, 95% confidence interval [95% CI] = 12.21–106.97), cats (OR = 3.94, 95% CI = 1.36–11.38), rock piles (OR = 5.28, 95% CI = 1.64–16.98), and bushes with height above 10 m (OR = 11.21, 95% CI = 2.08–60.45). These factors could be used to target surveillance and control of to houses with an increased risk of being infested.
