Our Process
01
Our process begins with a comprehensive inspection to diagnose the specific ant species and pinpoint the source of the infestation, which is critical for effective treatment.
Given the damp Tumwater winter, we meticulously search for common entry points and nesting sites for moisture ants, examining areas like crawlspaces and foundation cracks where they seek shelter from the December cold.

Service Types
We tackle ant problems in Tumwater with targeted treatments designed for the Pacific Northwest’s most common species. Our technicians apply professional-grade residual insecticides like Bithor SC or Temprid SC to baseboards, entry points, and exterior foundations, creating a barrier that stops ants before they get inside. For example, we treat around windows, doors, and utility penetrations where ants typically enter, then follow up with exterior perimeter applications to eliminate colonies at their source.
Our approach combines interior spot treatments with comprehensive exterior work. We focus on the areas where ants are most active. Then we extend protection around your home’s foundation and landscape beds.
Most ant issues are covered under our All Seasons Protection Plan, which includes quarterly maintenance and free callbacks if ants return between scheduled visits. We also offer one-time treatments starting at $325 for homeowners who prefer single-service solutions. Our treatments typically show results within 24 to 48 hours, with full elimination in the following days.
We protect Tumwater’s commercial properties from ant invasions with targeted treatments designed for the unique needs of local businesses.
