Pre-Purchase Rodent Inspection Los Angeles

We inspect the full exterior of the structure: roofline, eaves, soffits, vents, chimney base, foundation, garage, and any attached structures. Inside, we check the attic for nesting material, droppings, and entry gaps. In homes with crawl spaces, we go under the structure.

The output is a written report with photos that identifies every active or potential entry point, documents evidence of current or past activity, and provides a clear scope of recommended work. Buyers use it to negotiate repairs or credits before close of escrow.

Same-week inspection availability is typical during most of the year. October through February is our busiest period in the San Fernando Valley, so scheduling earlier in the fall gives you the most flexibility. Real estate transactions with escrow timelines get priority scheduling when the timeline requires it.

Standard pest control kills or traps the animals already inside. It does nothing to close the gaps they used to enter. A new group of roof rats can colonize an open attic within weeks, especially in Reseda where mature street trees connect property to property.

Exclusion addresses the structural problem, not just the animal population. Once every entry point is sealed, there's nowhere for new animals to go. See the full comparison: rodent exclusion vs. extermination.

California law requires landlords to maintain habitable conditions, and a rodent infestation fails that standard. A documented exclusion with a professional inspection report is your best protection against tenant claims and city inspection failures.

We provide documentation in a format that's useful in both situations. See specifics: California landlord tenant rodent law and landlord rodent compliance California.

The material depends on the gap type and location. Hardware cloth (galvanized steel mesh) is used at vent openings and larger gaps. Xcluder fill fabric handles irregular gaps in walls and pipe penetrations. Concrete or mortar fills foundation cracks and masonry gaps. We don't use foam sealants alone because roof rats can chew through them.

Properly installed steel and concrete exclusion work is indefinite, barring structural shifts in the building. Exposed hardware cloth on rooflines should be inspected every few years for corrosion in coastal-adjacent climates. Reseda's inland location means less salt exposure than coastal LA, so longevity is generally better.

The species is the same - Rattus rattus. But the San Fernando Valley's seasonal temperature swings are more extreme than coastal LA. Summer highs routinely exceed 100 degrees F, which drives roof rats indoors for temperature regulation, not just food. That means the entry-seeking behavior in the Valley starts earlier in summer and is more aggressive than in, say, Santa Monica.

Reseda's dense residential streets and mature tree canopy create ideal aerial travel routes for a species that prefers to stay off the ground. Homes with Italian cypress, eucalyptus, or large palms adjacent to the roofline are at higher risk. More context: roof rats Los Angeles guide.

DIY exclusion is possible for accessible, visible gaps at ground level. The problem is that most of the gaps roof rats use are on the roofline, inside soffits, or at the attic gable vents. Missing one gap means the job is incomplete, because a roof rat only needs an opening the size of a quarter.

We see the same DIY pattern repeatedly: foam or steel wool stuffed into visible gaps, but the animal is still active because there's an unsealed entry under the eave overhang or at the chimney cap. The tradeoff is real inspection time and aerial access vs. the cost of doing it twice. Full breakdown: DIY rodent proofing vs. professional.
