The Elevation Of Urban And Residential Areas Of Arizona Determines When Termite Swarms Emerge
At least 45 termite species have been documented as inhabiting the United States, and 30 of these species are known to inflict damage to structural wood or wood products. While Arizona is home to 17 termite species, only five are considered species of serious economic importance. In addition to causing a greater amount of property damage than any other pest species in the world, termites can also be a nuisance to homeowners. While subterranean and drywood termite workers are responsible for locating and initiating destructive indoor infestations, termite swarmers (alates) can annoy homeowners during the spring and early summer seasons, as swarms are of significant size and they often emerge in residential and urban areas where some species gravitate toward porch lights and street lights.
Termite swarms emerge when queen termites secrete pheromones that prompt reproductive alates to take flight from existing colonies. These swarms are comprised of male and female alates that attempt to find a mate in order to establish new colonies in areas where termites may not normally pose a threat to the structural integrity of homes and buildings. Fortunately, about 99 percent of swarming alates die before establishing a new colony as queen and king. Unfortunately, the alates that do survive often establish new colonies near the artificial light sources that lure them into human-populated areas.
There exists three subterranean termite species in Arizona that are considered highly destructive pests. One of these species, the arid-land subterranean termite, naturally inhabits unpopulated desert regions where they feed on vegetation. One reason as to why this species is becoming progressively more destructive is because new homes and buildings are being built over land where these termites are abundant. When structural developments remove their natural food source, the termites naturally turn to structural wood as their primary source of sustenance. This explains why swarms are so common within and near new homes in Arizona. While experts state that arid-land subterranean termite swarms occur in between the months of January and March, this is not always the case, as swarms emerge at different times of year depending on the elevation where colonies are established. In urban and residential areas below 4,000 feet in Arizona, residents can expect swarms to emerge during the winter and early spring seasons, but at elevations higher than 4,000 feet, arid land subterranean termites swarm during June and July.
