AtticShield’s Proven Process to Keep Rodents Out—Permanently
If you’re a homeowner in San Diego, chances are you’ve heard scratching in your walls or attic, seen droppings, or caught a glimpse of a rodent darting out of the corner of your eye. Rodent problems are more common in our region than most people realize—especially in older homes or properties near canyons, parks, or coastal areas.
At AtticShield, rodent proofing isn’t just pest control—it’s structural defense. Our team doesn’t rely on poison or temporary fixes. We locate every entry point, seal your home completely, and help restore a safe, clean, rodent-free environment. In this guide, we’ll walk you through:
- Why rodent proofing is essential in San Diego
- Signs of rodent infestation in attics and crawlspaces
- The dangers rodents pose to your home and health
- Our detailed rodent proofing process
- Long-term prevention tips
- What makes AtticShield different
Let’s dive in.
Why Rodents Are a Big Problem in San Diego
San Diego’s mild climate, abundant food sources, and aging infrastructure make it a paradise not only for people—but for rats, mice, and squirrels too. Common San Diego rodents include:
- Roof rats (Rattus rattus) – Often enter from overhanging trees or rooftops
- Norway rats (Rattus norvegicus) – Larger, burrowers that damage foundations and crawlspaces
- House mice (Mus musculus) – Small, fast, and often found in walls and insulation
Rodents are year-round invaders in Southern California. Whether it’s the cooler winter months or dry, hot summers driving them inside, once they get in—they nest, multiply, and wreak havoc.
Signs You Have Rodents in Your Attic or Crawlspace
Here are the most common indicators San Diego homeowners notice:
- Scratching or scurrying sounds—especially at night
- Droppings in the attic, garage, kitchen, or near vents
- Gnaw marks on wood, wiring, or insulation
- Grease marks or oily smears along baseboards
- Urine smells in enclosed spaces
- Chewed ductwork or insulation
- Visible holes or gaps in siding, vents, roofing, or foundations
If you notice even one of these signs, it’s time to act before the infestation spreads.
The Hidden Dangers of Rodent Infestations
Rodents may seem small, but their impact is enormous:
🦠 Health Hazards
Rodents carry dozens of diseases—including hantavirus, salmonella, leptospirosis, and even plague. Their droppings and urine can cause respiratory problems, especially in children and seniors.
🔥 Fire Risks
Rodents often chew electrical wiring. This creates real fire hazards and costly electrical issues.
🏚️ Structural Damage
Rodents tear through insulation, ducts, drywall, and even wood framing. Over time, this can degrade your home’s efficiency, comfort, and resale value.
🐁 Rodent Reproduction
One pair of rats can produce hundreds of offspring in a single year. Waiting only makes the problem worse—and more expensive to solve.
How Rodents Are Getting In
Most homeowners are shocked to find how many entry points rodents exploit:
- Gaps in roof tiles, fascia boards, or eaves
- HVAC line entries that aren’t sealed properly
- Damaged crawlspace vents or garage corners
- Plumbing penetrations, dryer vents, or chimneys
- Cracks in foundation walls or exterior siding
- Unprotected attic vents or gable ends
If a hole is the size of a quarter, a rat can squeeze through it. Mice only need a dime-sized gap. That’s why true rodent proofing requires sealing every vulnerable spot—not just setting traps.
Our Rodent Proofing Process at AtticShield
We’ve developed a thorough, step-by-step rodent proofing system tailored for San Diego homes:
🧰 1. Full Inspection
We begin with a comprehensive attic and crawlspace inspection. Our specialists identify:
- Active rodent nesting areas
- Entry and exit points
- Droppings, urine stains, and damage
- Chewed wires, ducts, and insulation
- Moisture or ventilation issues that attract pests
You’ll receive photos, videos, and a detailed report outlining everything we find.
🔒 2. Entry Point Sealing (Rodent Exclusion)
We permanently seal every rodent entry point with professional-grade materials:
- Galvanized steel mesh (not chicken wire or foam)
- Concrete patch, stucco patch, or wood blocking
- Silicone caulking and weatherproof sealants
- Steel plate barriers where needed
We seal around roof edges, vents, pipes, and any other vulnerable areas to exclude rodents without harming them.
🧼 3. Attic and Crawlspace Sanitation
If rodents have contaminated your insulation or attic with droppings and urine, we offer professional sanitation services, including:
- Removal of all biohazards and waste
- Deodorizing and disinfecting the space
- Optional insulation removal and replacement
This step is vital for your family’s health and to eliminate pheromones that attract new pests.
🪤 4. Trap Installation & Monitoring
While sealing the home prevents new rodents from entering, any that remain must be removed. We install professional-grade traps in the attic and return two times, two weeks apart, to inspect and remove any catches. No poisons are used.
🧾 5. Warranty & Follow-Up
We stand by our work. AtticShield offers a 1-year rodent-free warranty on all rodent-proofing jobs. This warranty applies specifically to the areas where work was performed. We’ll even provide documentation for your records, inspections, or future home sale.

Can’t I Just Call a Pest Control Company?
Most pest control companies offer temporary solutions like poison bait stations. These may kill some rodents—but don’t stop new ones from getting in. They also leave behind contaminated droppings, and dead animals may rot in your walls or attic.
Only rodent proofing seals your home and solves the problem at its source.
Tips to Keep Rodents Away (Even After We Leave)
Here are 6 proactive steps you can take after our rodent proofing is complete:
- Trim trees 3+ feet away from your roofline
- Store food in sealed containers
- Avoid leaving pet food out overnight
- Seal trash bins tightly
- Fix plumbing leaks or moisture issues
- Inspect attic annually for signs of rodent activity
We’ll walk you through all these tips at your final walkthrough.
