Collection of cockroaches from Manaus resulted in six species associated to human house, commercial buildings and educational buildings, being four species found predominantly indoor, Blatella germanica (Linnaeus, 1758), Supella longipalpa (Fabricius, 1798), Periplaneta americana (Linnaeus, 1758) and P. australasiae (Fabricius, 1775) and two species found predominantly outdoor, Pycnoscelus surinamensis (Linnaeus, 1758) and Blaberus parabolicus Walker, 1868 the latter two occasionally houseinfesting species in the rainy season. P. americana was common either indoor and outdoor and P. australasiae infesting mainly boats. Color figures in natural size are presented for all species in order to help their identification.
