Current Pest Advisory for San Gabriel Mission (August 2026)

As August heat settles over San Gabriel Mission, the combination of historic architecture and lush greenery creates a perfect storm for two pests: subterranean termites and mosquitoes. The old adobes and raised wood foundations of homes along Mission Road and nearby streets are particularly vulnerable to termites, which thrive in the warm, dry conditions and are drawn to moisture retained by the fertile alluvial soils. The San Gabriel River corridor and the mission's historic irrigation channels (zanjas) provide standing water that breeds mosquitoes, especially with temperatures in the 80s-90s. Homeowners should look for mud tubes along foundations, hollow-sounding wood, or discarded wings near windowsills—signs of termites—and check for stagnant water in plant saucers, birdbaths, and low-lying areas near the river or zanjas where mosquitoes lay eggs. Given the age of many homes, a professional inspection is wise, as hidden termite damage can go unnoticed until it's severe. Below are the top-rated San Gabriel exterminators who specialize in these specific seasonal threats.
