Current Pest Advisory for Montrose (August 2026)

As August heat bakes the foothills, Montrose homeowners should be on high alert for two persistent invaders: roof rats and ants. The dry, 85-degree weather drives these pests to seek moisture and shelter inside your Craftsman and mid-century homes, many of which have settled foundations and gaps around pipes and vents—perfect entry points. Your proximity to the Angeles National Forest and the dense brush on nearby hillsides creates a natural habitat for rodents, especially along streets like Hermosa Avenue and Ocean View Boulevard where mature trees overhang roofs. Roof rats are excellent climbers and will use those branches to access your attic, while ants—particularly Argentine ants—are marching in columns along foundations and through crawlspaces in search of water. Look for droppings in the garage, gnaw marks on wood or wiring, and trailing ants on patios or near basements. Also check for rub marks along walls or fences, and listen for scurrying sounds in the attic at dusk. These pests are not just a nuisance; they can damage your home's structure and contaminate food. Below are the top-rated Glendale exterminators who specialize in these specific seasonal threats.
