Cockroaches are the classic apocalypse-friendly bug.
German cockroaches, it turns out, are inching closer and closer to invincibility, according to Fox News.
“Cockroaches developing resistance to multiple classes of insecticides at once will make controlling these pests almost impossible with chemicals alone,” said one scientist. Essentially, they can’t be killed with just one type of insecticide.
Besides that, cockroaches can eat anything, even rotten food, have an “expanded family of immunity genes,” and can grow to be up to two inches long.
Cockroaches were reportedly seen to be scurrying around the wreckage after the atomic bombs were released in Hiroshima and Nagasaki – the Mythbusters even proved that cockroaches can survive that amount of radiation.
