Do you treat the inside of the home?

Most termite treatments focus on the exterior and surrounding soil. Interior treatments are only used when inspection shows they’re truly necessary.

Gene Wright began professional pest work in 1998, and founded Planet Friendly Pest Control in 2010 to bring that experience to homeowners across Northern Virginia and Southern Maryland.

Subterranean termites live in the soil and move into homes from the ground up. That means the most effective place to stop them is before they reach the structure, not inside living spaces.

In Northern Virginia and Southern Maryland, homes often have basements, crawlspaces, slabs, and foundation walls that give clear exterior access points. Treating these areas allows professionals to protect the home without disrupting daily life indoors.

Many homeowners ask this question because they’re worried about safety, pets, kids, or inconvenience. That concern is valid—but interior treatment is not the default approach.

For most homeowners, this is reassuring.

Exterior-first treatment means:

Interior treatment is reserved for specific situations—such as confirmed activity inside structural wood that can’t be addressed from the outside alone. Even then, it’s targeted, not blanket coverage.

The goal is always effective protection with the least intrusion possible.

• Minimal disruption inside the home
• No need to move furniture or empty rooms
• Protection focused where termites actually travel

A professional approach starts with inspection, not assumptions.

During inspection, we determine:

Most homes can be protected through soil and foundation work alone. Interior treatment is only recommended when inspection clearly shows it’s needed to stop ongoing damage.

This inspection-first mindset avoids unnecessary work and keeps treatment focused.

• Where termites are active
• Whether activity can be addressed from the exterior
• If any interior areas truly require attention
• How to protect the structure long-term

To support an exterior-focused approach:

A good explanation should always come before any work.

• Keep soil, mulch, and wood from touching siding
• Control moisture near foundations and crawlspaces
• Provide access to basements or crawlspaces for inspection
• Avoid DIY interior treatments that can hide activity
• Ask your inspector to explain why any interior work is suggested

This information is provided by Planet Friendly Pest Control, a locally owned pest control company serving Northern Virginia and Southern Maryland.

Our recommendations are based on real-world experience protecting homes in this region since 1998. We focus on inspection-first, exterior-focused termite control using the least amount of treatment necessary to protect the structure, families, and pets.

Every home is different. That’s why our guidance is based on how termites actually behave in local soil, moisture, and construction conditions—not generic advice or one-size-fits-all solutions.

If termites are suspected, a professional inspection will clarify whether interior treatment is needed—or if exterior protection is enough. Most homeowners are relieved to learn that interior work isn’t required.

An inspection gives you answers without pressure. You’ll know what’s necessary, what’s not, and why.

If you’re in Northern Virginia or Southern Maryland, Planet Friendly Pest Control takes an exterior-first, inspection-driven approach to termite control—focused on protecting the structure while keeping your living space comfortable.

Do all termite treatments involve indoor work? No. Most do not.

Is interior treatment unsafe? When used, it’s targeted and planned—but often unnecessary.

Why avoid interior treatment when possible? Because termites originate outside, and exterior control is usually more effective.

Will you explain if interior treatment is needed? Yes. Any recommendation should be clearly explained before work begins.
