Hire a professional for carpenter ant infestations

What to Do

Contact a licensed pest control professional when you find evidence of carpenter ants — frass (sawdust-like debris), hollow-sounding wood, or large ants (6-13mm) seen regularly indoors, especially at night. Get quotes from 2-3 companies.

Why It Works

Carpenter ant colonies nest inside wall voids, soffits, and rafters where DIY treatments cannot reach. Professionals use wall-void injection equipment, borescopes to locate nests, and professional-grade products. Multiple satellite colonies often exist in a single structure, requiring a systematic approach.

Tips

• Carpenter ants do not eat wood (unlike termites) but excavate it for nesting, causing structural damage over time
• The underlying moisture problem must be fixed or the ants will return
• Cost: $200-300 one-time for a standard home; $800-1,200 for severe infestations
• Ask about warranties and follow-up visits included in the price
