Science: Cold-Weather Cockroach Invades NYC

by Greg Pollowitz

A new species of cockroach that can withstand freezing temperatures has taken up residence in New York, scientists confirmed.

The resilient critter, Periplaneta japonica, had never been seen in the United States until an exterminator spotted some strange-looking roach carcasses last year on the High Line, a mile-long park built on an old elevated railway in Manhattan. Researchers confirmed the identity of the species, which is native to Asia and notable for its ability to thrive in cold climates, unlike the American cockroaches that populate New York and take shelter indoors when winter comes.

“About 20 years ago colleagues of ours in Japan reared nymphs of this species and measured their tolerance to being able to survive in snow,” Rutgers insect biologist Jessica Ware said in a statement. “As the species has invaded Korea and China, there has been some confirmation that it does very well in cold climates, so it is very conceivable that it could live outdoors during winter in New York. That is in addition to its being well suited to live indoors alongside the species that already are here.”. . .
