ARIZONA BUG FACT: Why do the monsoons bring sudden swarms of flying termites to the Phoenix metro area? 🌧️🐜
As the Arizona monsoon season kicks off (running from mid-June to September), local homeowners often witness a dramatic nature event: massive mating swarms of flying subterranean termites.
These winged termites—known scientifically as alates—are reproductive members of the colony. But why now?
1. The Humidity Trigger: Subterranean termites, particularly our native desert species Heterotermes aureus, require extremely high humidity (usually above 85%) and damp soil to swarm without drying out
2. The Rainfall Cue: Saturated soil from heavy monsoon rain acts as a green light. It softens the ground, making it easier for newly mated termite queens and kings to burrow and establish new underground colonies
3. Gravity & Light: These winged swarmers emerge at twilight or nighttime, showing a heavy attraction to patio lights, windows, and outdoor lighting
How to Tell the Difference: Winged Termite vs. Flying Ant- Before you panic, check these physical markers to see which pest is swarming your property:
1. Antennae: Termites have straight, bead-like antennae. Flying ants have bent or "elbowed" antennae
2. Waist: Termites have a thick, straight body with no defined waist. Flying ants have a narrow, pinched "wasp" waist
3. Wings: Termite swarmers have four wings of equal size and length that are translucent. Flying ants have front wings that are significantly larger than their hind wings
If you spot swarming activity or discarded insect wings around your foundation, doors, or windows after a monsoon storm, it means an active subterranean colony is nearby
