for Eastern Subterranean Termite
Swarms are seasonal — on warm spring days after a rain — but the timing shifts by region. Source: https://extension.missouri.edu/publications/g7420
The South sees it sooner: Texas A&M Urban Entomology reports swarming starts in South Texas in January and February, while in the Texas Panhandle swarms hold off until April and May. Farther north it runs later — Penn State gives a February-through-June window in Pennsylvania, and UGA places the swarm February through April.
