by In 2025, bed bug infestations have become a significant concern across several California cities, with both residents and public health officials working to combat the persistent and growing problem. Pest control companies report a steady increase in service calls, especially in urban areas with high population density, heavy travel activity, and aging infrastructure.
From large metro centers to mid-sized cities, the impact is being felt across the state. Here are five California cities currently facing serious challenges with bed bug infestations.
Los Angeles
Los Angeles remains one of the most bed bug–infested cities in California. Its massive population, constant flow of tourists, and widespread apartment living create the perfect conditions for these pests to thrive. Local exterminators note that multi-family housing, hotels, and public transportation hubs are common sites for recurring infestations.
The city has seen a consistent rise in reported cases over the past year, and while treatment efforts are ongoing, reinfestation remains a major issue.
San Francisco
In San Francisco, the bed bug problem has steadily worsened, particularly in older buildings and densely packed neighborhoods. Residents in apartment complexes and shared housing have reported multiple incidents, often resulting in costly extermination treatments.
The city’s housing shortage and the presence of older infrastructure with hidden crevices make it challenging to fully eliminate infestations. Public health officials are urging residents to report cases early and follow treatment protocols strictly to prevent further spread.
Sacramento
Sacramento has experienced a notable uptick in bed bug activity in recent years. The state capital’s growth in population and rental properties has contributed to a spike in infestations, particularly in apartment buildings and long-term housing units.
Local pest control professionals have reported a significant rise in service requests, and public outreach campaigns are being launched to educate tenants and landlords about early detection and professional treatment options.
San Diego
San Diego has not been spared from California’s bed bug resurgence. The city’s hotels, rental properties, and military housing have all seen an increase in bed bug-related service calls. Tourists, business travelers, and residents unknowingly transport the insects through luggage and personal belongings, enabling them to spread rapidly.
In response, San Diego officials have encouraged routine inspections and public education efforts to help identify and manage infestations early.
Fresno
Fresno, located in the Central Valley, has also emerged as a hotspot for bed bug activity. Local reports indicate that infestations are becoming more common in both residential and commercial properties. The city’s mix of older homes and transient populations contributes to the issue, with many residents struggling to afford the repeated treatments necessary to fully eliminate the pests.
Bed bugs in Fresno have also been reported in schools, shelters, and public housing facilities, prompting concern among health officials.
Conslusion
Bed bugs are proving to be a persistent and costly issue across California in 2025. As infestations continue to affect cities large and small, experts emphasize the importance of early detection, professional treatment, and increased public awareness to combat the problem. Without coordinated prevention and response strategies, these pests are likely to remain a long-term nuisance for many Californians.
