Integrated methods to control German cockroaches, Blattella germanica (L.), were carried out in a shopping mall. The methods which contain spraying permethrin alcohol and Blattanex, fumigating with Kincho, scattering toxic baits, and employing SIEGE (Gel insecticide) were employed two times interval two weeks. The results were monitored by sticky cards and showed that average density of cockroach was 47.14 per sticky card for a night in place of amusement, 35.2 in westen-style-food kitchen, 27.17 in site of electrical installation, 23.25 in coffee bar, and 20.08 in.Chinese meal kitchen .
