Remedies for both carpenter ants and odorous house ants have become much more effective in recent years. Pest Control Northwest studied these advances in depth, waiting to offer services until treatments became available that could meet customer expectations without requiring overtreating the entire home in order to eradicate ants in a single (unknown) area.

Trey can now use these up-to-date, low-impact treatments combined with advanced gel baits to successfully rid your home of these pests. Long term prevention may require periodic retreatments of perimeter areas in order to stop ants from re-entering the structure. Talk to Trey about a plan for your home.

Borate wood preservative treatments are becoming more common in the Northwest, following the great success of this method in the termite-plagued Southeast region of the country. Fungus cannot grow on treated wood, and insects ingesting borate are eliminated.

Moisture ants, on the other hand, should be viewed as our friends, for they tell us about water problems that usually need immediate attention. The ants produce a dark colored sawdust from rotted wood as evidence of a water leak. Without intervention, water fed fungus can cause many thousands of dollars of unseen damage to wood structures. Correcting the problem sooner than later is always the best route. As a licensed contractor, Trey can accomplish any needed repairs.

Pest Control Northwest recommends having Trey inspect your crawl space once a year for any evidence of moisture ant activity or other problems.
