Current Pest Advisory for Adams Hill (August 2026)

This August, the hot, dry conditions in Adams Hill are driving two pests into homes: roof rats and drywood termites. The lack of rainfall and scorching temperatures push roof rats to seek water and cooler shelter, and they are adept at exploiting the gaps in the tile roofs of your 1920s Spanish-style homes and the complex foundations of mid-century moderns. The heavy vegetation on the undeveloped slopes and the terraced gardens provide ideal harborage, allowing rats to easily travel onto your property and gnaw through attic vents or chew into basements—which, given the moisture issues common in these hillside homes, offer an inviting oasis. For drywood termites, the warm, dry summer is prime swarming season, and your older homes with exposed wood beams and less-treated lumber are vulnerable. Keep an eye out for rat droppings near food sources, rub marks along walls, or sounds in the attic at night, and for termites, look for discarded wings near windowsills and small piles of sawdust-like frass, especially around the tile roof eaves and wooden balconies that are quintessential to Adams Hill's architectural charm. Below are the top-rated Glendale exterminators who specialize in these specific seasonal threats.
