El Cajon sits in a valley ringed by hills, and that inland setting runs hotter and drier than the coast. The climate suits both roof rats and Norway rats, and the mix of older housing, ranch-style homes, and mature yards gives them plenty of places to feed and nest. Rodents move freely between the brushy hillsides and the neighborhoods below.
Roof rats work the attics and rooflines the same way they do across the county, using trees, fences, and utility lines to reach the roof. In the lower, older parts of El Cajon, Norway rats are more common near drainage, sewers, and crawlspaces, where they burrow and enter at ground level. House mice round out the picture, staying close to kitchens and garages year-round.
Because El Cajon homes vary so much in age and construction, the inspection is where the job is won. We check the roofline and attic for roof rat entry, the foundation and crawlspace for Norway rat access, and the interior for the small gaps mice use, then seal all of it before trapping out the rodents already present.
The hills and canyons around El Cajon keep sending rodents toward the houses at their edges, so sealing the home is what turns a temporary fix into a lasting one. Call and connect with a local rodent exterminator serving El Cajon and the surrounding valley.
