This indicates that B. germanica may be a possible reservoir and potential vector of some food-borne pathogens. Journal of Medical Entomology, 41(5):953-960. In addition to this globalisation and increased trade between countries increases the likelihood of it spreading between countries. Other reports suggest that entomophilic nematodes such as Neoaplectana carpocapsae and Steinernema carpocapsae could provide acceptable control of B. germanica (Zukowski, 1984; Manweiler et al., 1993).

In 2005, the role of one of these proteins, pigment dispersing factor (PDF), was isolated and found to be a key mediator in the circadian rhythms of the cockroach. [104][105] Both cockroaches have a restricted distribution and are threatened by habitat loss and rising sea levels. The egg case protrudes from the posterior of the adult female and the nymphs often hatch from the case while the female is carrying it. The cockroaches can live up to one month without any food but it can’t survive up to a week without water. [56], While cockroaches do not have lungs as do vertebrates, and can continue to respire if their heads are removed, in some very large species, the body musculature may contract rhythmically to forcibly move air in and out of the spiracles; this may be considered a form of breathing.

Hydramethylnon baits and sticky traps and Blattella germanica (L.) (Dictyoptera: Blattellidae) behaviour.
