In the war between humans and cockroaches, the pests have won a major victory—and it's thanks to our love of sugar. The Atlantic explains how the insects have adapted to our traps.

In the centuries-long war between humans and cockroaches, the most bitter blow was dealt roughly 40 years ago.

The secret was sugar: Cockroaches, like us, simply couldn’t resist their sweet tooth.
