California is facing a surge in bed bug infestations, with several major cities experiencing significant challenges as these resilient pests spread rapidly. The problem is driven by factors such as increased travel, resistance to traditional pesticides, the popularity of secondhand goods, and high-density housing. Here’s a look at the six California cities most actively battling this bed bug onslaught, and how they are responding.
1. Los Angeles: The Epicenter of Infestation
Los Angeles consistently ranks among the top cities in the nation for bed bug problems. The city’s dense population, status as a major travel hub, and extensive public transportation system create ideal conditions for bed bugs to spread.
Infestations have been reported in hotels, apartments, public transit, and entertainment venues, with cases rising by over 35% annually. The city has responded with mandatory disclosure laws for landlords and expanded public awareness campaigns to help residents identify and address infestations quickly.
2. San Francisco: Ongoing Battle
San Francisco’s high housing density and expensive rental market contribute to persistent bed bug issues. Both residential and commercial properties are affected, prompting city authorities to enforce stricter disclosure requirements and encourage early detection. The city’s approach emphasizes tenant and landlord cooperation and the use of innovative pest control techniques.
3. San Diego: A Growing Concern
San Diego’s warm, humid climate allows bed bugs to thrive year-round. The city has seen a noticeable uptick in cases, leading to increased public education efforts and the adoption of advanced pest management strategies. Local authorities are focusing on prevention and rapid response to limit the spread of infestations.
4. Oakland: Rising Risks
Oakland has reported a significant increase in bed bug infestations, largely due to high housing density, frequent travel, and the movement of secondhand goods. Local government efforts include raising public awareness and providing resources for prevention and treatment, as well as promoting cooperation between tenants and landlords.
5. Long Beach: Battling the Surge
Long Beach is another hotspot, with rising reports of bed bug activity. Like other major California cities, Long Beach is focusing on educational campaigns, mandatory disclosure requirements, and encouraging both residents and landlords to act quickly at the first signs of infestation.
6. Orange County: The Hidden Threat
Orange County, including cities like Irvine and Santa Ana, is experiencing an unprecedented surge in bed bug cases, with pest control calls up 35% since late 2024. High-risk areas include coastal hotels, multi-unit housing, and college dorms.
The county’s response includes professional heat treatments, targeted chemical applications, and increased monitoring, alongside public education to help residents recognize early warning signs and seek prompt treatment.
Why the Surge and How Cities Are Responding
The rise in bed bug infestations across California is attributed to increased travel, pesticide resistance, secondhand furniture, and high turnover in short-term rentals. Cities are responding with a combination of legislative action (such as mandatory disclosure laws), public education, and innovative pest control methods like heat treatments and preventive monitoring.
Tenant and landlord cooperation is central to effective bed bug management, and California law requires landlords to maintain habitable, pest-free properties.
Los Angeles, San Francisco, San Diego, Oakland, Long Beach, and Orange County are at the forefront of California’s battle against bed bugs. Through a mix of policy, education, and advanced pest control, these cities are working to contain the spread and protect residents and visitors from this persistent pest problem.
