This research shows the results of a study of house infesting ants in the city of Manaus, Amazonas. It was compared two seasons (dry and rainy), two activity periods (day and night) and four different rooms of the house (living-room, bedroom, kitchen and bathroom). All the residences were infested with at least one type of ant. Twenty one species were collected, seven of them are considered as characteristic of human habitats, and of these three are exotic ants. The larger diversity was observed during the rainy season and during the night. The kitchen was the room with larger occurrence of ants, whereas the diversity was similar among the rooms. Tapinoma melanocephalum was the most common species, being found frequently with other ant species.
