Monsoon season is more than a break in the sweltering summer heat for Phoenix residents. This quick shot of moisture between July and September sets the stage for the emergence of one of Arizona’s most destructive pests: termites. As dark clouds hide the Valley sky above and the year’s most rainfall falls in a few hours, homeowners from Ahwatukee to Deer Valley grimace at the thought of thousands of winged termites preparing to swarm.
The dry landscape and monsoon moisture surrounding Phoenix combine with the area’s clay-rich soil to create the perfect trifecta for subterranean termites to thrive. Each year, millions of dollars in property damage and loss are inflicted by these ravenous insects across Maricopa County. During the rainy season, if you see any flying termites around your property, call a pest control professional from Green Mango Pest Control.
Why Termite Swarms Peak During Phoenix Monsoons
-
Moisture Awakens Dormant Colonies
The desert termites that infest Phoenix homes and other properties are mostly dormant through the dry months, but monsoon rains can bring them out in force. Dormant termite colonies are called to biological arms when soil moisture temporarily explodes from near-zero to saturation.
-
Temperature and Humidity Create Perfect Storm
While tipping temperatures drop from 115°F to the mid-90s, humidity surges from 15% to over 60% during Phoenix monsoons. This sudden change in the atmosphere creates the precise environmental conditions necessary for a successful termite swarming event.
-
Soil Softening Enables Movement
They form highways under our feet, but designed for different climates, hard-packed desert soil only becomes tractable after heavy rains, when they then bore new tunnels to widen their networks. Soil has softened enough that colonies spread towards Phoenix homes, particularly those built on the area’s typical caliche.
-
Increased Food Sources
The Valley greens up after monsoon rains, and termites access freshly sprouting cellulose. During this time, dead plant matter, fallen branches, and saturated landscaping mulch become a magnet for termites.
-
Swarming Synchronization
In the high-intensity monsoon storms of Phoenix, swarming events from many colonies on the same day have been observed. Research at Arizona State University has shown that about two-thirds of all termites in the Phoenix metro area swarm within 48 hours of rain during those monsoon events.
Why Swarming Season Is a Red Flag for Homeowners
Termite swarms are not simply an annoyance; they are nature’s alert that the local colonies have done well. The emergence of reproductive termites around Phoenix homes indicates that large colonies have been feeding uninterrupted on wood for decades.
This timing, however, makes swarming especially troublesome for those in the Phoenix area. During the monsoon season, when families are mostly indoors due to the storms, it is hardly noticeable when termites cause considerable damage. Moreover, the added moisture not only causes swarming but also speeds up the feeding and reproduction rates of termites for the entire season.
Seek Professional Help!
Dealing with the termite swarms that occur during the monsoon season is best left in the hands of a professional, who can provide property-specific treatment options based on your home. Desert termite control requires special consideration, from caliche soil penetration to extreme temperature ups and downs; desert termite control experts need local know-how.
For efficient pest control against termites during the monsoon season, Green Mango Pest Control has established its name all over the Phoenix area. They know how the Valley’s weather patterns influence termite activity and integrate treatment strategies that consider the unique environmental factors of Arizona. Their technicians understand the particular termite species found throughout Phoenix neighborhoods and use relevant control strategies for the matter at hand.
