How Cockroaches Are Becoming Invincible


Cockroaches--or at least German ones--are becoming invincible. Researchers have found that Blattella germanica are becoming increasingly resistant to almost every kind of chemical insecticide. According to Science Magazine, not all insecticides are created equal. Some degrade the nervous system, whereas others attack the exoskeleton. But many insects, including cockroaches, have evolved resistance to at least one of the most commonly-used insecticides. And because cockroaches live only for about 100 days, that resistance can evolve quickly. What's more, the genes from the most resistant cockroaches are being passed to the next generation. Just how the cockroaches are evolving is unclear without further genetic testing. But widespread resistance could make it impossible to treat cockroach infestations with chemical insecticides alone.
