Pest Control Cost in California: 2026 State Price Guide

Last updated: March 5, 2026

By James — 25-year pest control industry veteran

Pest control cost in California ranges from $100 to $700 per treatment, with the average homeowner paying around $200 for general pest service. California is the largest pest control market in the US, with costs running 10 to 20% above national averages. Drywood termites requiring fumigation, strict rodenticide regulations, and the high cost of doing business in the state all contribute to higher prices.

This guide covers pest control pricing across the state of California, broken down by region and pest type. For national pricing, see our pest control cost guide.

California Pest Control Costs by Service

Regional Cost Breakdown

Termites in California

California has significant termite pressure, with both subterranean and drywood species active across much of the state:

• Drywood termites. Common in Southern California and coastal areas. They live entirely inside wood without soil contact and are the primary reason for tent fumigation in the state. Fumigation costs $1,500 to $5,000+ and is more expensive in California than most other markets.
• Subterranean termites. Active statewide, particularly in areas with irrigation and landscaping. Liquid barrier treatment ($300 to $1,000) and bait station systems ($800 to $1,500) are the standard methods.
• WDO reports. California uses a unique reporting system with Section 1 (active infestations, infections, and damage) and Section 2 (conditions likely to lead to infestation). Who pays for the inspection and treatment is negotiated between buyer and seller and varies by county custom.

Rodent Control Under AB 1788

California law AB 1788 (the California Ecosystems Protection Act) restricts the use of second-generation anticoagulant rodenticides (SGARs) to protect wildlife like raptors, mountain lions, and bobcats that suffer from secondary poisoning when they eat rodents that have consumed bait.

This means professional rodent control in California relies primarily on:

• Trapping ($250 to $600). Snap traps and mechanical traps placed strategically and monitored on a regular schedule.
• Exclusion ($500 to $2,500). Sealing all entry points to prevent rodents from entering the home. This is the most important and cost-effective long-term service.
• First-generation rodenticides. Still permitted but less effective and require more bait consumption, making trapping and exclusion the preferred professional approach.

The emphasis on exclusion and trapping makes rodent control in California more labor-intensive and expensive than in states where poison bait is the primary method. For more detail, see our rodent exterminator cost guide.

California-Specific Pest Challenges

• Argentine ant supercolonies. California is home to massive Argentine ant supercolonies spanning hundreds of miles. These ants displace native species and invade homes in enormous numbers, particularly during rain events and hot weather.
• Black widow spiders. Common throughout California, particularly in garages, sheds, and outdoor structures. Professional treatment targets harborage areas with residual spray and web removal.
• Gophers and ground squirrels. Major landscape pests throughout the state. Gopher removal costs $150 to $500 and uses trapping (the most effective method) or bait stations.
• Bark beetles. A significant concern in mountain communities and forested areas. While primarily a tree pest, bark beetle infestations can affect homes with wood siding in affected areas.
• Bed bugs. Major cities like LA, San Francisco, and San Diego rank among the worst for bed bug infestations. Heat treatment ($1,500 to $4,500) is the preferred method in California's apartment and condo markets.

California Pest Control Licensing

The California Structural Pest Control Board (SPCB) regulates pest control in the state with three license branches:

• Branch 1: Fumigation
• Branch 2: General pest control
• Branch 3: Termite and wood-destroying pests

All pest control operators in California must be licensed by the SPCB. Verify a company's license at the SPCB website before hiring. California has some of the strictest pesticide regulations in the US, which contributes to higher treatment costs but also provides stronger consumer and environmental protections.

What Affects Pest Control Cost in California

• Region. Bay Area and LA metro cost 15 to 30% more than the Central Valley due to labor costs and cost of living.
• Rodenticide restrictions. AB 1788 makes rodent control more labor-intensive and expensive in California than other states.
• Termite species. Drywood termites requiring fumigation ($1,500 to $5,000+) are significantly more expensive to treat than subterranean termites.
• Property type. Multi-unit buildings, condos, and properties with limited access cost more per treatment.
• Service frequency. Quarterly plans cost less per visit than one-time treatments.
