Most pests come from the outside in. A one-time exterior treatment establishes a protective barrier around your home’s foundation, entry points, and common harborage areas — no interior access required.
It’s an ideal option for seasonal pressure from ants, spiders, boxelder bugs, and other invaders, and a convenient choice when you’d rather we work entirely outside.
