Current Pest Advisory for Old Town Pasadena (August 2026)

As August heat bakes the historic streets of Old Town Pasadena, two pests are particularly active right now: drywood termites and roof rats. The prolonged dry spell and 85°F average temperatures push termites into swarming season—they're seeking new wood to infest, and the older Victorian and Craftsman homes with their raised foundations and poorly ventilated attics provide perfect targets. The dense tree canopy along Colorado Boulevard and near the Arroyo Seco offers roof rats ample harborage and food, while the aging infrastructure of these early 20th-century homes gives them easy entry points. The cool, humid microclimate near the Arroyo Seco also supports moisture-loving pests, but the current dry conditions are driving termites and rats indoors in search of water and cooler environments.

Homeowners in the 91101 and 91103 ZIP codes should inspect their attics for drywood termite signs like discarded wings near windowsills or piles of frass (wood-colored droppings) that look like salt and pepper. Look for mud-like tunnels on exterior walls, though drywood termites don't build mud tubes—instead, check for hollow-sounding wood when tapped. For roof rats, listen for scratching or scurrying in the attic at night, check for droppings (similar to rice grains) in the garage or crawlspace, and look for gnaw marks on wires or rafters. Also, inspect the roofline and eaves for entry points, especially where tree branches overhang—common along streets like Fair Oaks and Raymond Avenue, where mature oaks and sycamores touch rooflines. Below are the top-rated Pasadena exterminators who specialize in these specific seasonal threats.

About Old Town Pasadena, Pasadena

🏘️ Neighborhood

Old Town Pasadena is the historic core of Pasadena, centered along Colorado Boulevard near the Arroyo Seco. This densely developed district features a mix of historic commercial buildings and dense residential blocks with small lots and mature trees. The proximity to the Arroyo Seco creates a cooler microclimate and higher humidity, which can increase moisture-loving pests like termites and silverfish.

🏠 Housing

Homes in Old Town date primarily from the late 19th to early 20th centuries, with many Victorian and Craftsman styles on raised foundations with crawlspaces. Older wood-frame construction and aging infrastructure provide numerous entry points for rodents and insects. Attics in these historic homes often lack modern ventilation, creating ideal conditions for roof rats and drywood termites.

🌄 Terrain & Climate

The terrain is flat to gently sloping, with well-drained sandy loam soils from the Arroyo Seco floodplain. Despite good drainage, the area's many alleys and old irrigation systems can create pockets of standing water after rain. The dense tree canopy, including large oaks and sycamores, provides harborage for squirrels and birds that can introduce parasites.
