We're already seeing swarms in South and Southwest Texas. Activity of the most common subterranean termite, primarily those species in the genus Reticulitermes , begins in January.
Swarms gradually move up into the northern regions of Texas as spring nears.
This termite is found throughout the state, decreasing in numbers in the northern reaches of the state. The Formosan subterranean termite, known to scientists as the Coptotermes formosanus , begins its swarming season in early summer, according to Gold. There are several ways to spot the pest. Outside, homeowners may see the flying insects that are drawn to the windows and sides of homes. Termites are not as easily noticed inside, but may be found because of the damage they are causing.
