While it is difficult to pinpoint a single country with the "most" bed bugs due to varying reporting standards, the United States and France are frequently cited as the epicenters of modern infestations. In the U.S., major urban hubs like Chicago, New York, and Philadelphia consistently top industry lists (like Orkin's Top 50) due to high population density and constant international travel. In Europe, Paris made global headlines in 2024 and 2025 for a widespread "outbreak" that affected public transit and cinemas, leading to a massive government response. The resurgence of these pests is a global phenomenon driven by increased international tourism, resistance to common pesticides, and a lack of public awareness. Regions in Asia-Pacific, particularly rapidly urbanizing areas in China and Australia, have also seen a sharp rise in cases. It is important to note that bed bugs are not a sign of poor hygiene; they are "hitchhikers" that thrive wherever there is high human turnover, making luxury hotels in developed nations just as susceptible as budget hostels in emerging markets.
