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.

Fire Ant Control in Old Town Calabasas: A Data-Driven Guide

In Southern California, red imported fire ants (Solenopsis invicta) infest over 30,000 acres annually, with the San Fernando Valley being a significant hotspot. Old Town Calabasas, with its Mediterranean climate of hot, dry summers and mild, wet winters, provides ideal conditions for these pests to thrive year-round, with activity peaking during warm months from April to October.

Fire ants are aggressive and build large mounds that damage lawns, electrical equipment, and irrigation systems. Their stings cause painful welts and can trigger allergic reactions in sensitive individuals. In Calabasas, the mix of housing types—from single-family homes with lawns to multi-unit dwellings—offers ample nesting sites, especially in sunny, open areas.

Understanding fire ant behavior is key to management. Colonies can contain up to 200,000 workers and multiple queens, making eradication challenging. Typical inspection costs range from $50 to $200, while treatment can vary from $100 to $500 per application depending on property size and infestation severity. Long-term control often requires repeated treatments.

Fire ant control in Old Town Calabasas requires understanding local climate and ant biology. With year-round pressure and seasonal spikes, integrated management—including baiting, mound drenches, and habitat modification—is most effective. Costs vary, but early intervention can reduce long-term expenses. Stay informed and use preventive measures to protect your property.
