New construction is not cockroach-proof
Census estimates count about 3,400 Arcadia homes built in 2000 or later, roughly one in six, alongside some 5,500 from the 1950s. Owners live in 58% of the city's occupied homes. A newer house may be built more tightly, but German cockroaches do not need a gap in the walls to get in: they arrive in moving boxes, used appliances, furniture and items that were sitting in storage.
Once inside, they settle where it is warm and close to food and water: under and behind the refrigerator, inside dishwasher and range voids, around a second kitchen or wet bar, and near water heaters. In a large house with several of those spots, we inspect each one and treat where the roaches are actually living, rather than spraying rooms they never visit.

The condo and apartment side of Arcadia
Arcadia is not only single-family homes. About 5,600 housing units are in buildings with five or more units, roughly 1,900 of them in buildings of 20 to 49 units, and around 8,000 households rent. In those buildings, cockroaches can move between units through shared plumbing and gather in trash rooms and garages.
Treating one condo while the source sits in a neighbor's unit or the trash room tends to give short-lived results. We work with homeowners' associations and property managers to inspect connected units, trash and utility rooms, and garage areas, then use monitors to show where activity remains between visits.

A Baldwin Avenue closure and what it means for restaurants
LA County's weekly closure report for October 5 to 11, 2025 lists a restaurant on S. Baldwin Ave in Arcadia that county inspectors closed for vermin infestation on October 3, 2025. It reopened on October 10, a week later. The report does not say whether the vermin were insects or rodents.
A week without service is a real cost for any kitchen. LA County Environmental Health handles Arcadia's restaurant inspections, so our commercial service is set up to leave a paper trail an inspector can follow: regular visits outside dining hours, close checks of storage shelving, dish machines, drains and the warm spaces under equipment, food-area-labeled products only, and a dated log after each service.
