Pest Control Devices
Treebark Termite and Pest Control (Torrance) is a locally owned and operated pest management company proudly serving Torrance and the greater Los Angeles area. With deep roots in Southern California, we specialize in safe, effective, and eco-friendly termite and pest control solutions for both residential and commercial properties. Founded with a commitment to better, safer pest control, Treebark was created after our team grew frustrated with the harsh chemicals and fumigation methods used by many large national companies. We discovered a naturally derived compound from South American tree bark (Ryania Speciosa) that effectively eliminates termites and pests while remaining safe for families, pets, and the environment. Our Torrance team brings decades of combined experience in termite inspection, treatment, and prevention. Owner Aaron Cunningham personally oversees operations with over 20 years of hands-on expertise in the industry. We are fully licensed in California (License #PR9342) and stay current with the latest innovations through our membership in the National Pest Management Association. What Sets Us Apart in Torrance Safe & Natural Treatments — We use advanced, naturally derived solutions that drive pests out and destroy colonies without the need for whole-home fumigation in most cases. Free Inspections — Comprehensive 35-point inspections with no obligation. Long-Term Protection — Treatments backed by up to a 1-year transferable guarantee. Local & Responsive — We run daily routes in Torrance and can often provide same-day or next-day service. Affordable & Honest — High-quality service at a better value than big national brands. Whether you’re dealing with drywood termites, subterranean termites, rodents, or general pests, our Torrance team provides targeted, low-impact solutions that protect your home without disrupting your family’s daily life.
