Rodent Exterminator Cost in Los Angeles: 2026 Price Guide
Last updated: March 5, 2026
Rodent exterminator cost in Los Angeles ranges from $200 to $900, with the average homeowner paying around $400. LA has a significant rodent problem driven by roof rats that thrive in the city's palm trees and citrus groves, and Norway rats in older neighborhoods. California's restrictions on second-generation rodenticides make professional trapping and exclusion the primary control methods, increasing the importance of hiring a qualified exterminator.
This guide covers rodent control pricing specific to the Los Angeles metro, the unique challenges of roof rats in Southern California, and what to expect from professional treatment.

Roof Rats: LA's Primary Rodent Problem
Roof rats (Rattus rattus) are the dominant rodent species in Los Angeles and are far more common than in most other US cities. Unlike Norway rats that burrow in the ground, roof rats are agile climbers that nest in trees, attics, and elevated areas.
Several factors make roof rats especially problematic in LA:
- Fruit trees. Los Angeles has millions of citrus, avocado, and fig trees in residential neighborhoods. Fallen fruit provides a constant food source for roof rats. Picking up fallen fruit daily is one of the most effective prevention measures.
- Palm trees. LA's iconic palm trees provide elevated nesting sites for roof rats. Dead fronds create protected cavities where rats build nests, often directly above homes.
- Mild climate. LA's year-round warm temperatures mean roof rats breed continuously. There is no winter die-off or dormant period to reduce populations.
- Roof entry points. Roof rats enter homes through damaged eave vents, gaps around roof tiles, openings where utility lines enter the attic, and deteriorated fascia boards. Older homes in neighborhoods like Silver Lake, Echo Park, Highland Park, and the Hollywood Hills are particularly vulnerable.
California Rodenticide Restrictions
California Assembly Bill 1788, signed into law in 2020, restricts the use of second-generation anticoagulant rodenticides (SGARs) to protect wildlife. These potent poisons caused secondary poisoning in raptors, mountain lions, bobcats, and other predators that ate poisoned rodents.
Under the law, professional pest control operators in LA rely primarily on:
- Snap traps. The most common method for interior and attic rodent control. Effective, immediate, and avoids the risk of poisoned rodents dying in inaccessible areas.
- Exclusion. Sealing entry points is the most important long-term strategy, and California's restrictions make it even more critical since poisoning is limited.
- First-generation anticoagulant rodenticides. Less potent baits that are still permitted but require rodents to feed multiple times before lethal effects occur.
- Electronic traps. Battery-powered traps that deliver a lethal shock. Used in some commercial and residential applications.
These restrictions make professional exclusion work more important in California than in states where stronger rodenticides are available. For more on trapping methods, see our guide to getting rid of rats and our mouse exterminator cost guide.
Exclusion Work in LA
Professional exclusion costs $500 to $2,500+ in Los Angeles, with higher costs reflecting the complexity of older homes and the emphasis on roof-level sealing for roof rats.
A thorough exclusion for a Los Angeles home includes:
- Replacing or screening damaged eave and roof vents
- Sealing gaps where utility lines, pipes, and cables enter the attic or walls
- Repairing damaged fascia boards and soffit gaps
- Installing galvanized hardware cloth over foundation vents
- Sealing gaps around garage doors and exterior doors
- Trimming tree branches to at least 4 feet from the roofline
Roof rats can squeeze through a gap the size of a quarter and jump up to 4 feet horizontally. A professional exclusion identifies every potential entry point, including those at the roofline that homeowners often miss.
What Affects Rodent Control Cost in LA
- Home age and style. Older homes (pre-1970) with deteriorating rooflines and unsealed utility penetrations require more extensive exclusion work than newer construction.
- Fruit trees and landscaping. Properties with citrus, avocado, or other fruit trees adjacent to the home attract rodents and may need more extensive exterior baiting and monitoring.
- Hillside homes. Properties in the Hollywood Hills, Silver Lake, and similar hillside neighborhoods face higher rodent pressure from surrounding brush and wildlife corridors.
- Severity. A minor mouse issue costs $175 to $400. An established roof rat infestation with attic nesting can cost $500 to $900+ for trapping and exclusion combined.
- Attic contamination. If rodents have been nesting in the attic, sanitation and insulation replacement ($500 to $2,000) may be needed after the rodents are removed.
- LA cost of living. Rodent control in LA costs 15 to 30% more than national averages due to higher labor costs and the California regulatory environment.
