by California, famed for its beaches and bustling cities, is now grappling with a less welcome distinction: a surge in bed bug infestations. In 2025, six major cities are on the front lines of this persistent pest problem, each facing unique challenges and deploying a range of strategies to protect residents and visitors.
Los Angeles: The Epicenter
Los Angeles consistently ranks among the top five most bed bug-infested cities in the United States. Its dense population, heavy tourism, and high turnover in hotels and rentals create ideal conditions for bed bugs to thrive and spread rapidly. LA’s public health officials and pest control companies have ramped up efforts through regular inspections in hotels, apartments, and public spaces.
Public awareness campaigns educate residents on the early signs of infestation, while professional extermination services, including heat treatments and chemical applications, are being promoted citywide.
San Francisco: Urban Density Dilemma
San Francisco’s high cost of living and dense housing make it a hotspot for bed bug outbreaks. The city has seen a steady increase in cases, affecting both residential and commercial properties. Local authorities are encouraging landlords and tenants to report and address infestations promptly.
Guidelines have been issued for safe disposal and treatment of infested items, and public education initiatives are targeting prevention, particularly in multi-unit dwellings.
San Diego: A Growing Concern
San Diego’s warm, temperate climate allows bed bugs to remain active year-round. The city now ranks among the top ten in the nation for bed bug infestations. Enhanced monitoring is underway in hotels and short-term rentals, with increased collaboration between pest control professionals and city agencies.
Educational materials are being distributed to help residents identify and prevent the spread of bed bugs.
Oakland: Rising Risk
Oakland has experienced a noticeable uptick in bed bug cases, attributed to high housing density and increased movement of people and goods. Community outreach efforts are underway to raise awareness in vulnerable neighborhoods. The city has formed partnerships with local pest control experts to ensure rapid intervention and is actively supporting tenants’ rights to timely and effective treatment.
Long Beach: Increased Vigilance
Long Beach is seeing a rise in bed bug reports, particularly in multi-family housing and hospitality venues. Authorities and property managers are conducting routine inspections in high-risk properties and offering resources for both prevention and remediation. Public messaging promotes best practices for handling secondhand furniture and managing travel-related risks.
Orange County: 2025 Surge
Orange County is facing a dramatic 35 percent increase in bed bug-related calls since late 2024. Infestations have been reported in hotels, dormitories, and luxury apartments. Local pest control companies are responding with advanced heat treatment technology, targeted chemical applications, and multi-room inspections. Many are now offering free property inspections and follow-up treatments to ensure complete eradication.
Prevention and Solutions
The bed bug onslaught in California’s largest cities is a reminder that vigilance, education, and swift action are crucial. As infestations rise, collaborative efforts between residents, property owners, and pest control professionals are essential to stem the tide and restore peace of mind across the Golden State.
