In the United States, over the past 2-3 years, especially in summer, there's been a continuous increase in bedbug infestations in buildings. According to data from the National Institute for the Study and Control of Bedbugs (INELP), the infestation level is more severe than in previous years. Research reports show incidents in various locations, including hotels and vacation rentals. The issue has spread to public places nationwide, including San Francisco International Airport, the U.S. subway system, high-speed trains, and movie theaters, especially in the New York area.
