Houston coastal pest control protocols align with publications from Texas A&M AgriLife Extension (Harris County) and the Texas Department of Agriculture.
Gulf Coast Subtropical Climate & Pest Drivers
Houston's humid subtropical climate (Zone 9a) provides year-round breeding conditions for pests. High ambient humidity prevents desiccation, allowing heavy infestations of American cockroaches (locally called "Palmetto bugs"), German cockroaches, and Asian tiger mosquitoes. In spring, warm humid evenings trigger massive swarms of invasive Formosan subterranean termites (Coptotermes formosanus).
