What This Means for Your Home

For most homeowners, this is reassuring.

Exterior-first treatment means:

• Minimal disruption inside the home

• No need to move furniture or empty rooms

• Protection focused where termites actually travel

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.

How Professionals Address It

A professional approach starts with inspection, not assumptions.

During inspection, we determine:

• 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

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.

What Homeowners Can Do Now

To support an exterior-focused approach:

• 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

A good explanation should always come before any work.
