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
• Rustling inside walls
• Winged ants in spring

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

Store sprays kill surface ants, not colonies.

Professional treatment eliminates:

• The main colony
• Satellite nests
• Entry points
• Future risk
