Abstract Background: Regarding the high exposure of cockroaches to insecticides in hospitals, the chance for development of resistance is increasing. Objective: To determine susceptibility of different strains of Belattella germanica L. to Lambadacyhalothrin and Cypermethrin insecticides. Methods: The strains were collected from 5 hospitals affiliated to Tehran university of medical sciences (Emam,Dr. Shariatii, Markaz e tebi, Ziaeian, Baharlou ). Susceptibility tests were carried out on 1-3 days nymphs according to WHO standard method in different time. Finding: Susceptibility tests on 1-3 days nymphs indicated that the strains of German cockroaches collected from hospitals mentioned above were all resistant to Cypermethrin and also with some susceptibility changes to Lambadacyhalothrin. Conclusion: The resistance observed in our study may be due to current use of insecticide for German cockroach control and hence the development of cross resistance to these insecticides.
