Rodent Exclusion & Attic Decontamination San Diego

Roof rats (Rattus rattus) dominate San Diego County coastal and canyon-adjacent communities, utilizing eucalyptus and palm canopies to jump directly onto tile, shingle, and flat roofs. In hilly neighborhoods like Mission Hills, Point Loma, and La Jolla, architectural roof junctions, Spanish tile barrel voids, dormers, and unmeshed crawl space vents provide direct access for rodents seeking warmth and nesting sites. Left unaddressed, rodents chew through electrical wiring, creating real fire risks, and soil cellulose or fiberglass insulation with pheromones, urine, and droppings that carry airborne pathogens.

Rodent exclusion is not basic bait placement. Traditional rodent control relies on toxic exterior chemical bait stations, which leaves dead animals to decay inside interior drywall cavities or risks secondary poisoning to neighborhood pets and native raptors in canyon zones like Scripps Ranch and Carmel Valley. Structural exclusion eliminates the pest highway permanently by mechanically closing every structural gap larger than 1/4 inch using non-corrosive metals, wire mesh, and pest-proof sealant compounds. This approach resolves the root infestation without locking homeowners into indefinite recurring chemical contracts.

Attic decontamination operates as a distinct medical-grade sanitation process. Once active animals are confirmed excluded or humanely trapped out, technicians don negative-pressure personal protective gear and use sealed HEPA vacuums running at 99.97% particulate capture to lift rodent droppings and biological debris without circulating fecal dust into living quarters below. Contaminated, flattened batting is extracted, and remaining wooden rafters, joists, and drywall surfaces receive a broad-spectrum, hospital-grade botanical disinfectant applied via ultra-low-volume (ULV) misting. This breaks down odor-causing bacteria, neutralizes leptospirosis and hantavirus threats, and destroys the pheromone scent trails that draw new rodent populations to the roofline.
