‘Impossible to kill’: Cockroaches are evolving

Cockroaches are becoming immune to bug sprays.

Cockroaches are being born impervious to bug sprays and it’s happening fast.

A Purdue University study found that the commonly found German species of roaches are being born with an immunity to toxins with which they haven’t yet been in contact. The shocking study, published on Live Science, concluded the evolution of the German cockroach, also called the Blattella germanica, develops an immunity to new poisons in as quickly as one generation of offspring.

“We didn’t have a clue that something like that could happen this fast,” study co-author Michael Scharf said. “Cockroaches developing resistance to multiple classes of insecticides at once will make controlling these pests almost impossible with chemicals alone.”
