The best time to protect a home from termites and ground-dwelling pests is before the slab is poured and the walls go up. Pre-construction treatment creates a chemical barrier in the soil that works for years — at a fraction of the cost of treating an established infestation.
Arizona building codes require pest control pre-treatment for most new residential construction — but the quality of that treatment varies widely. Zona's pre-treatment service meets and exceeds state requirements, using proven termiticide products applied correctly to ensure long-lasting protection from day one.
Treating a home for termites after it's built requires drilling through concrete, injecting product into established colonies, and working around a finished structure. It's invasive, expensive, and disruptive. Pre-construction treatment eliminates this by creating a continuous chemical barrier in the soil before the slab is poured — when the ground is fully accessible and treatment can be applied evenly and completely.
In Arizona, subterranean termites are present in virtually every area of the Valley. New construction sites disturb soil and often attract termite colonies looking for new food sources. Without a pre-treatment barrier, a new home can begin showing termite activity within the first few years — sometimes while still under construction.
Beyond termites, pre-treatment also addresses other ground-dwelling pests — including scorpions, ants, and crickets — that commonly colonize new construction sites and establish themselves in and around the structure before the first owner moves in.
Before the concrete slab is poured, we treat the sub-slab soil with a liquid termiticide (typically Termidor or equivalent). This creates an unbroken chemical barrier directly beneath the foundation — the most critical layer of protection against subterranean termites entering from below.
As the foundation walls are formed and backfilled, we treat the soil along the exterior foundation perimeter. This extends the barrier to cover the most common termite entry routes — wood-to-soil contact points and foundation gaps that subterranean termites exploit.
We provide the treatment certificate and documentation required by Arizona building inspectors and lenders. All product information, application rates, and coverage areas are documented for your records and the property file.
We recommend pairing pre-treatment with a Zona residential plan after move-in. The soil barrier provides long-term subterranean protection, while regular visits address above-ground pests, scorpions, ants, and any new pest pressures that develop as the landscaping matures.
Not all termiticides perform equally in the caliche-heavy, alkaline soils common throughout the Phoenix Valley. We use products specifically rated for Arizona soil conditions, and our application rates account for the sandy-clay profiles that affect product distribution and retention in desert soils.
We coordinate directly with your general contractor and construction schedule to ensure treatment happens at exactly the right phase — before the slab pour and during backfill. We understand construction timelines and won't hold up your build. We're also available for same-week scheduling when your pour date is set.
