Carpenter Ant Damage in Columbia, MD: Warning Signs & When to Call a Pro
Carpenter ants are one of the most destructive pests in Maryland. They don’t eat wood like termites, but they tunnel through it — causing structural damage the longer they go untreated.
If you're a homeowner in Columbia, MD, here’s how to spot carpenter ant activity early and when to call Home Advantage Pest Services.
How to Identify Carpenter Ants
Carpenter ants are larger than typical ants and often show up around:
- Windowsills
- Door frames
- Decks
- Kitchens
- Basements
If you notice sawdust-like debris (frass), that’s a strong sign of a nest.
Warning Signs
Watch for:
- Large black ants indoors
- Soft or hollow-sounding wood
- Piles of wood shavings

Why Carpenter Ants Are Serious
They can weaken:
- Deck supports
- Beams
- Window frames
- Joists
- Exterior siding
The tunnels expand quickly and worsen over time.
DIY vs Professional Removal

Professional treatment eliminates:
- The main colony
- Satellite nests
