Western Exterminator delivers pest control in California that addresses the critters that challenge California homeowners and businesses with targeted, expert solutions.
Cockroaches
Warm, humid areas like kitchens and basements attract German and American cockroaches. Our targeted bait stations and sanitation checks can eliminate hiding spots and help prevent reinfestation.
Ants
Whether pavement ants march across driveways or carpenter ants tunnel into wood, these colonies search relentlessly for food and moisture. Our ant control in California includes the removal of colonies and sealing of entry points to help prevent ant infestations.
Termites
Termites can feed unseen within walls, risking structural damage to wooden structures over time. Regular termite inspections can reveal early activity, and our tailored termite control in California can help protect your property’s wood components.
Birds
Pigeons, starlings, and other birds can nest on ledges and vents, leaving behind droppings that can pose health risks. Our bird control programs use exclusions and deterrents to block roosting sites and help safeguard your building.
We recommend scheduling routine visits every quarter to address common pests like bed bugs, ants, and rodents before they can establish. Properties with known issues or seasonal spikes may require monthly check-ins.
Our network covers major regions including Los Angeles, San Diego, San Francisco, Sacramento, Fresno, Santa Clarita, and surrounding communities.
We provide both localized barrier treatments and fumigation services to eliminate termite colonies. Combined with ongoing monitoring, these methods secure your property against future threats.
