What areas are sealed during exclusion work?

The process targets rooflines, roof vents, crawl space foundations, utility penetrations where pipes and wires enter, structural gaps in siding or stucco, and any openings rodents have used or could potentially exploit to access interior spaces.

How is exclusion different from regular pest control?

Exclusion physically seals entry points to prevent access, while recurring pest control programs manage rodent populations through repeated trapping or bait stations without addressing the structural vulnerabilities that allow continuous re-entry.

Can exclusion be done before an infestation occurs?

Preventative exclusion seals potential entry points on homes without current activity, which stops infestations before they begin and avoids the damage and contamination that occur once rodents establish nesting areas inside the structure.

What materials resist rodent chewing?

Exclusion uses metal screening, hardware cloth, concrete patching compounds, and other rodent-proof materials that cannot be gnawed through or displaced, unlike spray foam, caulk, or wood that rodents easily breach.

Does exclusion work apply to wildlife as well?

The same sealing approach prevents squirrels, possums, and other wildlife from entering through roof vents, eave gaps, and foundation openings, since these animals use similar access points to establish nesting sites in attics and crawl spaces.

Rodent Proofing & Exclusion

Every structure contains gaps, cracks, and openings that rodents exploit to gain access to attics, crawl spaces, and wall cavities. Simply Rodents seals these entry points using materials designed to resist chewing and prevent re-entry after infestations are cleared. In San Jose, where year-round mild temperatures allow continuous rodent activity, exclusion work eliminates the pathways that support recurring infestations rather than managing populations indefinitely through trapping alone.

Exclusion targets rooflines where fascia boards meet eaves, roof vents with damaged screens, crawl space foundation gaps, utility lines entering through unsealed holes, and structural joints that have separated over time. Rodent-proof materials fill these openings permanently, which means no holes equals no rats. The approach works for homes currently dealing with infestations and for properties seeking preventative protection before damage occurs.

Protect your property before damage accumulates by scheduling an exclusion evaluation to identify vulnerable access points.

Rodents enter structures through openings as small as a quarter inch for mice and half an inch for rats, exploiting construction gaps that most homeowners never notice until activity begins. Exclusion work seals every potential entry point using materials rodents cannot chew through or push aside, which eliminates their ability to access interior spaces regardless of population pressure outside the structure.

After exclusion is completed, you no longer hear scratching sounds that previously occurred in walls or attics, new droppings stop appearing in storage areas and along baseboards, and odors fade as contamination sources are no longer being refreshed by ongoing activity. The structure becomes physically inaccessible to rodents attempting entry from the exterior.

Exclusion does not address rodents already inside the structure, which is why trapping or removal work must occur first if current activity exists. Once the interior population is cleared and entry points are sealed, the infestation cycle stops because replacement rodents cannot follow the same routes that previous populations used to gain access.
