Exhaustive removal sampling represents a promising method for quantification of absolute indoor Aedes aegypti density, leading to improved entomological estimates of mosquito distribution. The study describes the use of sequential removal sampling to estimate absolute numbers of indoor resting Aedes in the city of Merida, Mexico. The study was performed in 200 houses based on recent occurrence of Aedes-borne viral illness in residents. The lack of a numerical association between relative and absolute density of adult Ae. aegypti represent a significant gap in vector surveillance. Merida is highly endemic for dengue and other Aedes-borne viruses.Bureau for Global HealthU.S Agency for International Development (USAID)US Centers for Disease Control and Prevention (CDC)Canadian Institutes of Health Research (CIHR
