Rats in the Alleys: Hawthorne's Rodent Problem Explained

Two rats, two routes

Hawthorne deals with two rats. Norway rats are bigger and work low, denning in ground burrows, storm drains, and the alleys, then pushing into garages, crawl spaces, and the ground floors of homes and businesses. Roof rats are smaller, agile climbers that travel fences, wires, and trees into attics and second-floor units.

Both are drawn to the same things: food, water, and cover. A dense grid of homes, alleys, detached garages, and the restaurants and markets along Hawthorne Boulevard gives them all three.

How they get in

Rats need surprisingly little space, a gap the size of a quarter for a rat, a dime for a mouse. Common entry points are foundation and garage-door gaps, utility and pipe penetrations, roof and vent openings, and the corners where the garage door meets the frame. Once in, they gnaw wiring (a fire risk), contaminate food, and breed quickly.

Because rats move between properties along the alleys and shared fences, one home can keep getting hit even after the rats inside are gone, if the entry points stay open.

Trapping plus exclusion

Bait alone leaves you guessing and can leave a dead-rat odor in a wall. The reliable fix is trapping plus exclusion: snap traps and tamper-resistant stations set on the runways rats actually use, then sealing every entry point with rodent-proof materials so the next rat working the block cannot get in.

Cutting the attractants matters too, secured trash, no open pet food, trimmed vegetation off the roofline, and no standing water. A local exterminator handles the trapping and the sealing and confirms the activity has stopped.
