Current Pest Advisory for Mulholland Corridor (August 2026)

As summer heat grips the Santa Monica Mountains, Mulholland Corridor homeowners should be on high alert for two pests: the Western black widow spider and the yellowjacket wasp. With temperatures hovering in the 80s-90s and no rain since spring, these pests are thriving in the dry, warm conditions typical of this high-elevation ridge. The black widow, a reclusive arachnid, seeks out the cool, dark recesses of your estate's detached structures—think barns, equipment sheds, and the secondary living quarters common on these large properties. Their presence is amplified by the abundant rodent population, which is drawn to the unkempt brush and woodpiles near the mandatory clearance zones. Meanwhile, yellowjackets are aggressively foraging for protein and sweets, making your outdoor dining areas and trash bins prime targets. The seasonal creeks that wind through the canyon provide moisture, while the expansive gardens and orchards offer nesting sites in the ground or within the walls of older 1980s-era homes. These social wasps are particularly active during the day, especially around pools and patios, and their nests can be hidden under eaves, in attics, or in the dense vegetation along your long driveways.

For black widows, look for irregular, tangled webs in undisturbed areas like crawl spaces, meter boxes, and the corners of your barn or shed. Their glossy black bodies and red hourglass marking are unmistakable—use a flashlight and wear gloves when inspecting. For yellowjackets, watch for increased wasp activity around garbage cans, compost piles, and outdoor pet food, and listen for a loud, continuous buzzing that may indicate a nest nearby. Check for entry points around rooflines, vents, and utility penetrations, especially on the newer 2020s builds, as these are prime access spots. Given the wildfire risk, any pest control measures must be executed with extreme caution, avoiding flammable sprays near dry brush. If you notice either pest, it's crucial to act quickly to prevent stings or bites, especially for children and pets. Below are the top-rated Calabasas exterminators who specialize in these specific seasonal threats.
