Termite Prevention Techniques and Inspections in Arizona

Many homes have a termite infestation at some level. The saying in Arizona is “there are two types of homes in Arizona; those that have termites and those that will have termites”.  While there are 3 varieties of termites the only one of concern in Arizona is the subterranean termite. And, although there are several varieties of subterranean termite, exterminators treat them all as one.

Subterranean termites live in nests underground and emerge only to forage for wood or wood based foods. They are very small, but very destructive. They require moisture to survive and they are only attracted to wood, cardboard or paper that has a 19% or higher moisture content. They do not “live” in the wood as other varieties of termites do, but form “mud” or shelter tubes on the walls or ceilings inside or outside the home to shelter them from the outside air and heat of the sun as they travel from underground where they live, to above ground where they eat. They must return to the underground nest roughly every day. 

The fact that they live underground is both bad and good: it makes them hard to detect until they have done damage however, because they return to the ground frequently it also makes it possible to expose them to termiticides applied or injected into the earth, thus killing them and the nest. Once termites have been discovered, remedial action can be very effective.

Pretreat the Soil Beneath the Building Foundation

The most effective measure against termites is pretreating the soil that will be under the footprint or the concrete slab of the building. This measure annihilates any termites present in the soil on contact and also creates an invisible barrier that prevents them from sneaking through cracks that develop in the slab as the home settles. Every builder in Arizona now pretreats the soil under their buildings; a practice in place since the 1960s. However, that barrier degrades over time, typically lasting for about 5 to 8 years.

Treat the Perimeter Every Couple of Years

Since the soil under the home was rendered a termite free area from the outset, it is important to conduct periodic perimeter treatments around the exterior of the building preventing any future infestations. This “booster” measure  should be undertaken every few years at most. This measure is a critical in preventing future infestations. Many providers offer these services with a warranty that covers any intermittent treatments and remediation should any termites slip through. These warranties vary in price starting around $300 up to $1000 and are usually based on the period of coverage, e.g. from 1 to 5 years.
