Rosemead's vermin closures, 2025 to 2026
KTLA's list of LA County Public Health closures for March 1–27, 2025 included at least five Rosemead food businesses shut for vermin infestation, on Valley Boulevard, Garvey Avenue and Rosemead Boulevard, and some reopened within a few days. The station's late-summer list added a Valley Boulevard restaurant closed July 25 that did not reopen until August 25, a Walnut Grove Avenue cafe closed August 12 for vermin, unsafe food temperatures and a score below 70, and a second closure on August 8 for a Valley Boulevard restaurant that had also been on the March list.
The county's own weekly report for October 5–11, 2025 shows a bakery on Garvey Avenue closed for vermin infestation on October 3 and reopened October 5. In August 2026, KTLA reported another Valley Boulevard restaurant closed for vermin on August 4. These closures are ordered under California Health and Safety Code section 114259.1, and the reports do not say whether the vermin were cockroaches or rodents.

Why a one-time spray doesn't hold in a busy kitchen
A restaurant that appears on the closure list twice in one year shows how quickly a cockroach population can rebuild once the pressure comes off. German cockroaches breed indoors in warm, damp spots such as cooler motors, dish stations and floor drains, and UC IPM notes that new infestations often arrive with supplies, which is why it recommends inspecting food deliveries and checking boxes and appliance motors for egg cases.
Along Rosemead's commercial strips, many kitchens sit in multi-tenant plazas where neighboring units are likely to share walls, ceilings and plumbing, so a problem next door can become yours. A recurring program, which for restaurants usually means monthly service, keeps bait fresh, catches new introductions on the monitors and gives you a running record.
LA County Environmental Health inspects every Rosemead food facility. Our visits are timed before opening or after close, use gel baits, insect growth regulators and trapping with products labeled for food areas, avoid broadcast spraying near food surfaces, and end with a written log you can show an inspector.

Rented houses and townhomes behind the boulevards
Away from the commercial strips, Rosemead is mostly houses: about 72% of its 15,447 homes are detached and another 14% are attached townhome-style units, while fewer than one in ten is in a building with five or more units. Even so, 7,613 of the city's 14,434 households, about 53%, rent, so many renters live in houses, back units and townhomes. The median home was built in 1959.
In a rented house, cockroaches often trace back to things the tenant can't fix alone: a leak under the sink, a gap behind the stove, a water heater closet that never gets opened. We show the tenant what to prepare and give the owner a short written list of repairs that will keep roaches from returning.
Rosemead is one of the most multilingual cities we serve. Census estimates count about 18,000 residents who speak Chinese at home, roughly 10,800 who speak Spanish and about 7,300 who speak Vietnamese. Our technicians speak English and Spanish, and our website is also available in Chinese and Vietnamese.
