Current Pest Advisory for Old Town Calabasas (August 2026)

As we're in the thick of August's dry heat, Old Town Calabasas is seeing a spike in two specific pests: roof rats and German cockroaches. The historic adobes and multi-unit buildings along the creek corridor provide perfect harborage for roof rats, who are actively seeking water and food sources. With the Calabasas Creek running year-round, these rodents have a reliable water source and travel along the riparian zone, easily accessing attics and eaves of older structures like those near the Leonis Adobe. Meanwhile, the commercial kitchens and outdoor dining areas at The Commons are a magnet for German cockroaches, which thrive in the warm, humid microclimates created by food waste and irrigation runoff. The shared walls in mixed-use buildings allow roaches to move freely between units, making infestations spread quickly.

Homeowners should be on the lookout for rat droppings (dark, rice-sized pellets) in garages, attics, or along fence lines, as well as gnaw marks on utility lines or fruit trees. For cockroaches, check behind refrigerators, under sinks, and in bathroom cabinets for small, pepper-like feces or shed wings. Also, listen for scratching sounds in walls at night—a classic sign of roof rats. Given the historic nature of many properties, sealing gaps around pipes and rooflines is crucial. Below are the top-rated Calabasas exterminators who specialize in these specific seasonal threats.
