Knight Termite & Pest Control has served San Diego and Riverside Counties from Suite 9 at 4620 Alvarado Canyon Road in Grantville, 92120, since the company's founding in 1989. The firm holds a BBB A+ rating with accreditation dating to 2009, and its Structural Pest Control Board licenses cover fumigation, general pest, and termite work. Termite-damage restoration on Grantville's older commercial and residential structures runs concurrently with water-damage and structural-repair scopes handled by SERVPRO of San Diego East in Allied Gardens, whose crews address interior framing and drywall while Knight handles the wood-destroying-organism remediation. Treatment options for drywood termites include tent fumigation with sulfuryl fluoride, thermal heat treatment for localized infestations, chemical spot application, and non-chemical orange-oil injection for homeowners who prefer a reduced-toxicity approach. The company changed ownership in 2018 and continued its multi-county service footprint, running scheduled routes through College Area, Allied Gardens, San Carlos, Del Cerro, La Mesa, and Santee from the Alvarado Canyon dispatch point. General pest-control services cover ant, cockroach, spider, earwig, silverfish, flea, cricket, and bee infestations through interior-exterior perimeter treatments on monthly, bimonthly, and quarterly rotation schedules. Rodent exclusion work includes attic and crawl-space entry-point sealing, snap-trap and bait-station deployment, and sanitation recommendations to eliminate harborage conditions in San Diego's older housing stock. Post-fumigation air-quality concerns in sealed structures often prompt duct and dryer-vent cleaning, and Chipper Dryer & Air Duct in Grantville runs those clearance services on properties where fumigant residue in HVAC ductwork needs mechanical removal before reoccupancy. The Alvarado Canyon Road corridor near the I-8 interchange gives the dispatch fleet direct freeway access to residential neighborhoods across eastern San Diego County without routing through surface-street congestion.
