The risk factors of pupal infestation with community-based Aedes aegypti were identified in four areas of Playa municipality, located in the urban zone of Havana City The deposits with the highest positivity to the vector were the artificial ones and the low tanks. It was confirmed that 99.03% of the sites visited contained at least one deposit with water, and that 4 areas presented a very similar behaviour in ratio of tanks per site, since in all of them the water was supplied every other day. That is why the difference in the positivity was not due to factors related to the water supply. Of the positive deposits, 87.17% were located in backyards, and 91.3% of the positive low tanks had no cover, or were partially covered. It was found that in the positivity of the deposits to the dengue vector, only 8.7% were non-community dependent. If there had had an active participation of the community directed to cover the tanks, to change the water in the water troughs, and to clean the backyards, the pupal infestation due to Aedes aegypti would have drastically increased in the studied areas.
