apartment building – cockroach infestation spatial relationships

apartment building - cockroach infestation spatial relationships

In a high-rise apartment building, researchers led by Changlu Wang, Ph.D., at Rutgers University, examined the spatial distribution of German cockroach (Blattella germanica) infestations among residential units. Prior to the application of a building-wide integrated pest management (IPM) program, the researchers found cockroach distribution in the building was not random or independent; instead, if one apartment was infested, so were neighboring apartments that were adjacent, across the hallway, or directly above or below. After a 12-month IPM program, the distribution correlations were weakened significantly. (Image originally published in Zha et al 2019, Journal of Economic Entomology)
