New construction pest control in South Florida: what your builder did, what they skipped, and what runs out

  • 10 Mins Read
You bought a brand new home in Boca Raton, Boynton Beach, Wellington, Port St. Lucie, or Stuart. Everything is fresh. Clean drywall, sealed floors, new appliances, and not a single pest in sight. The builder handed you a folder of warranties and paperwork at closing, and somewhere in that stack is a termite pre-treatment certificate you probably glanced at and filed away.

Three to five years from now, that pre-treatment will have degraded in the soil to the point where it no longer provides meaningful protection. Your new home will have the same termite vulnerability as every other home in the neighborhood. Nobody at the closing table mentioned that part.

At a glance

What the builder actually did

Florida building code requires a termite pre-treatment on all new residential construction. Before the slab was poured, a licensed pest control operator applied a liquid termiticide to the soil beneath and around the foundation. UF/IFAS documents this pre-construction soil treatment as the standard approach for subterranean termite prevention in Florida new construction.
The treatment creates a chemical barrier between the soil and the concrete slab. Subterranean termites traveling through the soil toward the structure contact the treated zone and are either killed or repelled before reaching the foundation.
This is real protection, and it works. For a while.

How long the pre-treatment actually lasts

The termiticide applied before your slab was poured has a finite lifespan in South Florida’s sandy, well-drained soil. The active ingredient degrades through microbial activity, rainfall percolation, and the natural chemistry of the soil over time.

Most pre-treatment products used in Florida new construction provide effective protection for five to seven years under ideal conditions. In South Florida’s climate, with heavy rainfall, warm soil temperatures, and sandy soil that drains quickly, the effective lifespan is often closer to three to five years. Your builder is required to provide a one-year termite warranty. Some builders extend this to five years through the pest control company that performed the pre-treatment. After the warranty expires, the protection continues to degrade with no monitoring, no renewal, and no notification to the homeowner.

The pre-treatment certificate in your closing folder tells you when the treatment was applied and which product was used. It does not tell you when the protection will run out.

What the builder did not do

The pre-treatment addresses subterranean termites only. It does not protect against drywood termites, which enter from above through exposed wood, attic vents, and gaps in trim and fascia. It does not protect against any other pest species. Your new home has no general pest barrier. No rodent exclusion assessment. No mosquito management. No ant treatment. The builder’s scope ends at the termite pre-treatment because that is what the code requires. Everything else is the homeowner’s responsibility from day one. New construction also comes with conditions that attract pests independently of the pre-treatment.

Construction moisture.

New concrete, drywall, and paint release moisture for months after construction. That moisture attracts ghost ants, silverfish, and other moisture-dependent species into brand new homes that feel clean and sealed.

Fresh landscaping.

New mulch beds, sod, and irrigation systems installed during construction create immediate harborage for fire ants, ghost ants, and other ground-nesting species. The landscape is literally being built while the pests are already present in the soil.

Unsealed gaps in new construction.

New homes have gaps. Utility penetrations through the slab, pipe sleeves that were not sealed after plumbing was run, weep holes in concrete block that were not screened, and soffit panels that were installed quickly during the final construction push. These gaps are entry points from day one.

What drywood termites do to new homes

This is the risk most new construction homeowners in Palm Beach County and the Treasure Coast never consider.

Subterranean termites come from below, and the pre-treatment addresses that. Drywood termites come from above, and nothing the builder did protects against them. Drywood termites swarm during warm, humid evenings and land on exposed wood surfaces. New construction with fresh, untreated wood trim, fascia, and framing is attractive to swarming drywood termites. Our guide on termite pre-treatment in Florida covers how long the subterranean protection lasts and why drywood termite risk is a separate concern entirely.

A drywood termite colony that establishes in your attic framing during the first year of construction can grow undetected for years before producing the frass pellets that alert the homeowner. By the time you notice the small piles of sawdust-like material on a windowsill or in the garage, the colony has been feeding for a long time.

The timeline for new construction pest protection

Year one. The pre-treatment is at full strength. Subterranean termite risk is low. General pest pressure from construction moisture, fresh landscaping, and unsealed gaps is high. This is the year to schedule a professional inspection, seal construction gaps, and start a general pest prevention plan.

Years two through three.

Pre-treatment is still providing meaningful protection but beginning to degrade. General pest pressure from construction moisture decreases as the home dries out. Landscape beds are maturing and creating established harborage for ants and other species.

Home icon

Years three through five.

Pre-treatment effectiveness is declining significantly in South Florida's soil. This is the window where subterranean termite monitoring should begin. A bait station system installed around the perimeter at this stage catches any termite activity that reaches the degraded treatment zone.

Home icon

Years five through seven.

Pre-treatment may still have some residual activity but should not be relied upon as the primary protection. Ongoing termite monitoring is essential from this point forward.

What new homeowners should actually do

Home icon

Schedule a pest inspection in the first six months.

Not because your new home has pests, but because a professional eye catches the construction gaps, the landscape conditions, and the moisture situations that create pest opportunities before they become pest problems.

Home icon

Start a general pest prevention plan in year one.

Construction moisture and fresh landscaping attract pests immediately. Waiting until you see activity means the population has already established.

Home icon

Ask your builder for the pre-treatment certificate.

Know the product, the date, and the warranty terms. Mark the warranty expiration in your calendar so you know when to transition to active termite monitoring.

Home icon

Get a termite monitoring system installed by year three to five.

Do not wait for the pre-treatment to fully degrade before adding monitoring. Overlapping the protection ensures there is no gap.

Home icon

Have the attic inspected for drywood termite evidence annually.

The pre-treatment does not cover drywood termites, and new construction wood is attractive to swarming reproductives.

Call Wise House Pest Control

At Wise House Pest Control, we inspect new construction homes across Palm Beach County and the Treasure Coast regularly, and the conversation is always the same. The homeowner assumed the builder handled everything. The builder handled the minimum the code required. The gap between those two things is where the pest problems start.

If you bought a new home in the past one to five years and have never had a professional pest inspection, this is the right week to schedule one. Knowing what the builder did and what they did not do puts you in control of the timeline rather than waiting for the first signs of a problem.

Frequently Asked Questions

Yes. Florida building code requires a pre-construction soil treatment for subterranean termites before the slab is poured. The protection is real but degrades over time, typically lasting three to five years in South Florida’s sandy soil before it needs to be supplemented with monitoring.
No. The soil treatment only addresses subterranean termites that approach through the ground. Drywood termites enter from above through exposed wood, attic vents, and trim. New construction wood is attractive to swarming drywood termites, and annual attic inspection is recommended.
Between year three and year five after construction. The pre-treatment is degrading by this point, and installing a bait station monitoring system before it fully lapses ensures continuous protection with no gap.
Construction moisture in new drywall and concrete attracts ghost ants and other moisture-dependent species. Fresh mulch beds and sod installed during construction create immediate harborage for ground-nesting ants. Both conditions are normal in new construction and benefit from early treatment.
Yes. A professional inspection in the first six months catches construction gaps, unsealed utility penetrations, landscape conditions, and moisture situations that attract pests before populations establish. The builder addressed the termite code requirement. Everything else is the homeowner’s responsibility.
