Carpenter Ants in South Florida

Carpenter ants are South Florida’s largest ant species — and they’re often misunderstood. Unlike termites, carpenter ants don’t eat wood. They excavate it to build smooth, gallery-like galleries for nesting. But the structural damage they cause over time can be significant, especially in homes with existing moisture damage, rotting wood, or older construction.

How to Identify Carpenter Ants

Carpenter ants are large — 1/4 to 1/2 inch long — and typically black or dark brown. In South Florida, the Florida carpenter ant (Camponotus floridanus) is the most common species and is distinctive for its red-and-black bi-colored body. Workers vary greatly in size within the same colony. A key identification feature: carpenter ants have a single, rounded node (bump) between their thorax and abdomen — fire ants have two nodes.

Signs of Carpenter Ant Infestation

• Large black or red-and-black ants, especially indoors at night
• Small piles of coarse sawdust (frass) mixed with insulation bits and ant body parts near wooden structures
• Faint rustling or crackling sounds inside walls, floors, or ceilings — the sound of ants excavating wood galleries
• Perfectly smooth, clean galleries visible in damaged wood — unlike termite damage, carpenter ant galleries look finished
• Winged carpenter ant swarmers emerging indoors in spring — a sign of a mature, established colony

What Attracts Carpenter Ants to Your Home

Carpenter ants almost always establish satellite colonies near moisture-damaged wood. Per UF IFAS Extension, the #1 factor attracting carpenter ants to South Florida homes is wood that has been softened by moisture — roof leaks, plumbing leaks, water-damaged window frames, and wood-to-soil contact. Finding and fixing the moisture source is an essential part of carpenter ant elimination.

Frequently Asked Questions

How do carpenter ants differ from termites?

Carpenter ant damage shows clean, smooth galleries with sawdust-like frass outside. Termite damage is rougher and packed with soil or frass inside the galleries. Carpenter ants are larger and visible; termites are rarely seen directly. A free inspection from Bugsy’s will identify which pest is present.

Are carpenter ants dangerous?

They don’t sting, but large workers can deliver a painful bite. The more significant risk is structural: years of carpenter ant activity in moisture-damaged wood can cause serious weakening of structural elements.

Can I treat carpenter ants myself?

Over-the-counter ant sprays target foragers but rarely reach the nest. Professional treatment requires locating the nest — often in walls, rooflines, or outdoor trees — and applying targeted product directly to the colony.
