When Are Termites Most Active In Phoenix?

Termites are a significant concern for homeowners in Phoenix, Scottsdale, and Chandler, as well as throughout Maricopa County and all of Arizona, as the warm climate provides an ideal environment for these destructive pests. Understanding when termites are most active and recognizing the warning signs of an infestation is crucial for early detection and effective termite control.

When termites are most active in Phoenix

In the Phoenix area, subterranean termites are the biggest threat and remain active year-round due to the region's mild winters. However, they tend to be most active during the spring, summer (monsoon season), and fall months when temperatures rise, humidity levels increase, and moisture is readily available.

Warning signs of a termite infestation

Early identification of a subterranean termite infestation is vital to prevent significant structural damage. The following signs may indicate the presence of termites in your Phoenix home:

  • Termite swarmers
    Swarmers are winged termites that leave the colony to establish new colonies. If you observe swarms of flying termites near light sources, especially during spring, it is a clear indication of a nearby termite colony.

  • Discarded wings
    After a termite swarm, you may find discarded wings around windowsills, doors, or other entry points. Termites shed their wings after finding a mate.

  • Mud tubes
    Subterranean termites build mud tubes, often referred to as "termite highways," that they use to travel between their underground nests and food sources. These pencil-sized tubes can be found along foundations, walls, or other wooden structures and serve as protection against dehydration and predators.

  • The presence of “white ants”

    Because termites use mud tubes and reside within walls and in underground colonies in soil, it’s not very common to see foraging termites out in the open. That said, you might notice insects that look like white ants in the soil or inside a wall you’ve opened.

  • Hollow sounding wood
    Termites consume wood from the inside out, leaving a thin layer of wood or paint on the surface. If wooden structures such as walls or floors sound hollow when tapped, it may indicate termite damage.

  • Sagging or damaged wood
    As termites weaken the structural integrity of wood, you may notice sagging floors and buckling ceilings.

  • Tight-fitting doors and windows
    As termites create moisture within wooden structures, it can cause doors and windows to become tight-fitting or difficult to open or close.
