Dallas spreads across roughly 386 square miles of mostly flat Trinity River country, with hot, humid summers and spring storms. That mix of old neighborhoods, big lawns and busy commercial blocks gives several pests a steady supply of food, shelter and water.
Dallas counted 1,304,379 residents in the 2020 census, making it the third most populous city in Texas and the seat of Dallas County. It sits at about 482 feet above sea level and is split by the Trinity River, which is held between earthen levees roughly 50 feet tall. Oak Cliff was its own town until 1903, and its hilly northern part holds Kessler Park and the Bishop Arts District.
The city also has White Rock Lake, Bachman Lake and a long list of creeks and storm drains. Add average July and August highs near 96 degrees and about 39 inches of rain a year, and you get ideal conditions for ants, roaches and mosquitoes. Older frame houses add another draw for termites.
