Kensington sits on a mesa above Mission Valley, with Adams Avenue running through its small business district. Much of the neighborhood was built in the 1920s and 1930s, and Spanish Revival homes with clay tile roofs, stucco walls and arched windows give it its look. Mature trees shade most streets, and many yards have citrus, avocado and dense flowering vines.
Those tile roofs are a big part of the rodent story. The rounded ends of barrel tiles at the eaves leave openings unless bird stops are in place, and older roofs often have gaps where the tile meets a parapet or chimney. Roof rats use them to get into attics that may not have been opened in years. Many homes also sit on raised foundations, which opens the walls to rodents from below.
The neighborhood's edges are canyons. The north side drops steeply toward I-8 and Mission Valley, and fingers of canyon reach into the residential streets. Brush on those slopes holds rodents, and homes on the rim feel the pressure most. On some streets, rats come up from the canyon after dark, cross the backyard and climb the nearest tree or vine.
Adams Avenue has restaurants, cafés and small shops in older storefronts with shared walls. Those buildings have the same age-related gaps as the homes nearby.
If you call from Kensington, say whether your home backs onto a canyon and whether it has a crawl space. Ask the technician to check the tile ends and parapets, and to look under the house. Expect sealing to take more time than on a newer tract home. Cleanup in attics that have held rats for years can be a bigger job too. See rats in the attic. Trimming vines and branches that link the canyon brush to your roof cuts off the nightly route, and the county suggests a 4-foot gap between plants and the roofline.
