Common Ants in Pierce County & When to Call Pros
Pierce County homes see steady ant pressure from spring through fall. The three you’ll meet most often behave differently and respond to different approaches.
What are the most common ants in Pierce County?
Odorous house ants are the classic “sugar ant.” They are small, dark, and give off a rotten-coconut smell when crushed. They trail into kitchens and bathrooms looking for moisture and sweets. Colonies can be large and often have multiple nests, which is why surface sprays alone rarely solve the problem.
Carpenter ants are larger and can excavate wood. They prefer damp or damaged wood and are more likely to indicate a moisture issue. Seeing large black ants indoors, especially at night, is a signal to look for entry points and possible structural moisture.
Pavement ants nest under sidewalks, driveways, and foundations. They push small piles of soil out of cracks and will forage indoors when outdoor food is scarce.
Why do DIY sprays often fail?
Most store-bought sprays kill the ants you see but leave the colony intact. Odorous house ants in particular will simply shift trails or establish new satellite nests. Without addressing the nest locations, entry points, and the food/water sources that attract them, activity usually returns within days or weeks.
When should you call a professional?
Call for help when:
- Trails keep reappearing after multiple DIY attempts
- You see large carpenter ants or find frass (wood shavings) near baseboards or windows
- Activity is heavy in multiple rooms or around the exterior foundation
- You prefer a longer-term barrier instead of repeated reactive spraying
A professional treatment focuses on the areas ants actually use — perimeter bands, drip lines, entry points, and known nesting zones — and can be adjusted seasonally as pressure changes.
What does a typical professional approach look like?
At Bullpen we start with a walkthrough to identify species and pressure points. Treatments usually include exterior perimeter work, targeted interior applications only where needed, and recommendations for sealing gaps or reducing moisture. On our seasonal plans, free re-services are included if activity returns between visits.
