Scientists Uncover Critical Shift Behind the Massive Surge of Bedbug Infestations

Bedbugs have been pesky companions for humans for over 50,000 years. A recent study in Biology Letters reveals that as humans moved from caves to cities, bedbugs made the leap to thrive alongside us.

Researchers found that bedbugs split into two groups long ago. One group stuck with bats, while the other evolved to feast on humans. During the Ice Age, both groups struggled to survive. However, as human settlements grew in places like Mesopotamia about 12,000 years ago, bedbug populations skyrocketed. This made them one of humanity’s earliest pests.

Warren Booth, an urban entomology professor, explained that when modern humans left caves, they brought some bedbugs with them. This resulted in a less diverse genetic pool for the bedbugs that adapted to humans.

Focusing on recent trends, Professor Booth highlighted the resurgence of bedbugs over the last century. After the bug populations dropped significantly due to DDT, they made a comeback, quickly becoming resistant to many pesticides.

Statistics reveal a troubling rise in bedbug infestations, with incidents increasing by 35% from 2022 to 2024. Meanwhile, requests for cockroach exterminations grew by 13%. This trend reflects wider concerns about pest management and the effectiveness of modern methods.

The battle against bedbugs is ongoing and serves as a reminder of our shared history with these tiny pests. With increasing urbanization, it’s important to stay vigilant about pest control to maintain healthy living spaces.
