Do I Need Pre-Construction Termite Treatments for a New Home?

Buying or building a new home is one of the biggest investments you'll ever make — and unfortunately, it can also be one of the most vulnerable. While many people think termite damage is a risk for older homes only, the truth is that new construction is just as susceptible — and in some cases, even more so.

Why Termite Protection Matters — Even for New Homes

Termites can eat away at structural wood for years before anyone notices, potentially causing tens of thousands of dollars in damage and most homeowners insurance policies don’t cover it. By treating a home before it’s built (or before the foundation is poured), you create a long-lasting barrier against termite intrusion.

What Are the Types of Pre-Construction Termite Treatments?

Here are the most common options builders and pest control professionals use:

1. Liquid Termiticide Soil Treatment

• Applied to the soil before the foundation slab is poured
• Creates a chemical barrier that repels or kills termites trying to enter the structure
• Typically lasts several years, depending on the product and soil conditions

2. Wood Treatments

• Applied directly to wood framing during the construction phase
• Soaks into the wood and prevents termites (and other wood-destroying insects) from feeding on it
• Eco-friendly and odorless options; often used alongside soil treatments for double protection

3. Physical Barriers (Optional Enhancements)

• Includes sand barriers, mesh systems, or steel mesh around plumbing penetrations
• More common in certain building codes or termite-heavy areas

Are Pre-Treatments Required by Law?

In many regions, building codes or lender requirements mandate pre-construction termite treatment — especially in areas classified as moderate to high risk for termites.

Even where it’s not legally required, smart builders and homeowners choose to invest in it anyway. It’s a one-time treatment that can save a lot of money, hassle, and structural damage in the long run.

When to Schedule a Pre-Treatment

Pre-construction termite treatment needs to be coordinated early in the building process, typically:

• Just before the slab or foundation is poured (for soil treatments)
• During the framing phase (for wood treatments)

Working with a licensed termite prevention specialist ensures treatments are applied at the correct time — and that they comply with any local building codes.
