Pests that drive problems in Katy
- Termites (subterranean). Rapid new residential construction across Katy makes the pre-construction soil termiticide, applied before the slab is poured and the one full termite treatment per Texas A&M AgriLife, the key window for new-build buyers; older homes rely on remedial treatment instead.

- Mosquitoes. Katy sits on the Buffalo Bayou floodplain, and post-storm standing water is prime mosquito breeding habitat; females lay eggs on or near water that may collect, and warmer water tends to speed development, with the cycle running as little as four days depending on conditions. [source]
- Red imported fire ants. In a flood-prone area like Katy, red imported fire ant colonies leave their mounds and float until they can reach land when water rises, so floating rafts are a real post-flood hazard. [source]
Local factors
- Buffalo Bayou floodplain. Katy is centered near the tripoint of Harris, Fort Bend, and Waller counties on the fertile floodplain of Buffalo Bayou, within the coastal prairie. That low, flood-prone prairie setting keeps moisture-dependent subterranean termites and standing-water mosquitoes in play. [source]
Katy straddles the tripoint of Harris, Fort Bend, and Waller counties on the Buffalo Bayou floodplain, within the coastal prairie. That flood-prone setting keeps termites and mosquitoes in the picture, and rapid new-home construction makes the pre-construction termite soil treatment worth asking about before a slab is poured. Removing standing water after storms and sealing entry points do the most for a DIY approach.
