Cockroach German, Blattella germanica

On the other hand, the lethal efficacy for adult house flies (Musca domestica) is about the same as D-allethrin and approximately 0.5 that of prallethrin. In addition, the efficacy for female adult German cockroaches (Blattella germanica) is approximately twice that of D-allethrin and approximately 0.5 that of prallethrin. From the results mentioned above, we can see that Metofluthrin has an extremely high lethal efficacy for mosquitoes in particular. 

Relatively high concentrations of boron componnds are used to control fruitflies, cockroaches, gypsy moth larvae, houseflies, and woodboring insects (Sprague 1972 USEPA 1975 Table 29.6). Boric acid is an effective stomach poison for several insect species, including German cockroaches (Blattella germanica), that are unable to detect the presence of boric acid (USEPA 1975). Insect infestation of wood and other substrates can be prevented by pretreatment with boric acid or borax at...

The aggregation pheromones of insects can be classified into two groups those emitted by males or females to attract both sexes simultaneously for resource exploitation and/or mating (e.g., bark beetles Byers, 1989) and those emitted to attract and arrest individuals of specific developmental stages, as found in the German cockroach Blattella germanica (Ishii and Kuwahara, 1967,1968 Sakuma and Fukami, 1990, 1993).
