Live termite swarm forecast · updated July 20, 2026
Termites swarm on warm, humid days, and a swarm indoors usually means an established colony. TermiteZone gives you a daily swarm-risk score built from each species' swarm season and live local weather.

Live scores across the Termite Belt, from the Gulf Coast to Florida, Texas, the desert Southwest, and California.
We map each place to the termite species actually established there: native subterranean, invasive Formosan, drywood, and desert subterranean.
Every species swarms in its own window, from spring subterranean flights to the Gulf Coast's late-spring Formosan dusk swarms and late-summer drywood flights.
We fold in live temperature, humidity, and recent rain, so today's score reflects whether conditions actually favor a flight right now, not just the season.

A professional inspection is the only way to confirm termites, and a wood-destroying-insect report is often required for a mortgage. We'll connect you with a vetted local termite pro for a free, no-obligation quote.
