Japanese cockroaches love NY winter weather

Look out New York, there is a new cockroach in town, and it appears to be more adept at surviving outside in freezing temps giving them a definite advantage over the native species according to entomologist Jessica Ware, an associate professor at Rutgers University now studying the invaders from Japan.

Known as Periplaneta japonica, it is not clear how the 1” long rusty brown insects made their way from Asia to the Big Apple, and why they seem to have settled only in Manhattan’s West Side High Line Park (so far). One theory is that they came in on imported plants now lining the park.

What is clear, however, is that there are now “two types of cockroaches competing for the same space and food,” stated Ware, who went on to state,” when a migrating species arrives, the new and old rarely end up cohabiting. It is also very unlikely that the two species would cross-breed and create a hybrid super roach since they appear to be sexually incompatible.”
