Properties adjoining coastal canyons in Pacific Beach, Ocean Beach, and Point Loma face relentless climbing pressure from roof rats (*Rattus rattus*). These rodents routinely travel along telephone cables, bougainvillea vines, and eucalyptus canopies to access attic crawlspaces. Standard pest management programs frequently deploy exterior bait boxes that disperse anticoagulant chemicals into suburban ecosystems, endangering domestic pets and predatory native raptors hunting along Tecolote Canyon or Torrey Pines State Natural Reserve.

Chemical treatments also allow rodents to crawl deep into interior wall cavities before dying, producing persistent odors. Physical structural exclusion directly remedies this by reinforcing the architectural shell. Technicians install corrosion-resistant 19-gauge galvanized hardware cloth over attic gable vents, dormer air returns, and under Spanish barrel tiles, denying entry permanently without contaminating the interior air.

Common questions

How can I tell if roof rats are in my San Diego home?
Scratching sounds in ceilings between 10:00 PM and dawn, hollowed-out citrus rinds beneath backyard fruit trees, or tapered 0.5-inch droppings near attic insulation indicate an active roof rat infestation.
Can structural exclusion permanently stop rodents near San Diego canyons?
Yes, exclusion provides long-term control because roof rats cannot chew through 19-gauge galvanized wire or solid sheet flashing, even when dense native brush abuts canyon-rim lots in Scripps Ranch or Carmel Valley.
Is rodent exclusion safe for dogs and cats in San Diego?
Exclusion relies entirely on physical construction materials and contained interior traps, eliminating pet-toxic bait blocks and outdoor broadcast chemicals across San Diego properties.
Are recurring monthly contracts required for rodent exclusion in San Diego?
No ongoing monthly subscription is required for permanent structural exclusion, as sealing entry points solves the problem architecturally rather than maintaining perpetual outdoor bait traps.
What happens to rats already trapped inside a San Diego attic after exclusion?
Technicians deploy mechanical snap traps inside the attic space concurrently with the structural sealing, clearing out enclosed rodents within 5 to 10 days while monitoring the structure via follow-up inspections.
