How rodents get in across the city
Converted downtown buildings
Old office and commercial buildings turned into apartments keep their long utility chases, trash rooms and ground-floor restaurants. Mice and rats that get into one part of the building can follow pipe runs and wiring between floors, so a single unit is rarely the whole picture.
Houses on steep lots
On the steep streets of Mount Washington, Boyle Heights and the hills above Hollywood, many houses sit on posts or step down the slope, leaving open space under the downhill side. Brush growing close to the walls gives roof rats cover right up to the house.
Along the river and creeks
Homes near the Los Angeles River and Ballona Creek back onto long channels with brushy banks and storm drains. Norway rats burrow along banks and travel through drains, then reach houses at ground level through foundation vents and gaps around pipes.
Empty lots and job sites
Where lots sit empty or houses are going up, as across parts of Pacific Palisades, rodents look for shelter in the homes next door. Open framing, unfinished vents and stacked materials also give them places to hide until a new house is closed in.
In apartment buildings, rodents move between units through shared walls, pipe runs and garages, so a problem can start next door.
