Contrary to popular belief, most ants do not eat wood. Unlike termites, which consume wood for sustenance, some ant species tunnel through it to create nests. These ants prefer damp or decaying wood but may also infest dry wood in homes and structures.
Ant infestations can lead to structural damage if left untreated. Identifying the type of wood-nesting ants in your home is essential for effective pest control. The most common culprits include carpenter ants, moisture ants, and velvety tree ants.
Carpenter ants can weaken the integrity of wooden structures over time, making it crucial to address infestations as soon as possible.
Fixing moisture issues in and around the home is key to preventing moisture ant infestations.
These ants can also enter homes in search of food, making proper exclusion techniques essential.
While some ants tunnel through wood, they do not eat it like termites. Carpenter ants, moisture ants, and velvety tree ants are the primary species that nest in wood. Wood damage from ants can be prevented by addressing moisture issues, sealing entry points, and eliminating decaying wood. If an infestation is suspected, taking prompt action or seeking professional assistance can prevent further problems and protect your home from costly repairs.

Carpenter Ants
Carpenter ants are the most well-known wood-nesting ants. They do not eat wood but excavate it to create smooth tunnels for their nests. They prefer moist, rotting wood but may also invade sound structures.Signs of a Carpenter Ant Infestation
- Sawdust-like frass near wooden surfaces
- Rustling sounds inside walls
- Large winged ants appearing in warm seasons
- Hollow-sounding wood when tapped

Moisture Ants
Moisture ants thrive in damp, decaying wood but do not cause significant structural damage. Their presence often indicates underlying moisture problems in a home. These ants help break down rotting wood but can be a nuisance if they nest indoors.Characteristics of Moisture Ants
- Typically yellow or reddish-brown in color
- Found in damp, decaying wood
- Common in areas with high humidity or water damage

Velvety Tree Ants
Velvety tree ants are another species that burrow into wood. Like carpenter ants, they do not consume wood but tunnel through it to create nests. They are less destructive than carpenter ants but can still cause damage if left unchecked.Key Facts About Velvety Tree Ants
- Black or reddish-brown in color
- Emit a foul odor when disturbed
- Prefer nesting in trees, logs, and wooden structures
Prevent Wood-Nesting Ants
To prevent these ants from infesting your home, take the following measures:Ant Prevention Tips
-
Reduce Moisture: Fix leaks, improve ventilation, and use dehumidifiers in damp areas.
-
Seal Entry Points: Caulk cracks around windows, doors, and foundations to block access.
-
Remove Decaying Wood: Eliminate tree stumps, water-damaged materials, and other wood debris.
-
Store Firewood Properly: Keep woodpiles at least 20 feet away from your home and off the ground.
-
Trim Trees and Shrubs: Prevent branches from touching your house to reduce potential ant pathways.

How to Get Rid of Wood-Nesting Ants
If you suspect an infestation, take immediate action:
Locate the Nest
Look for frass piles and listen for rustling sounds inside walls.
Use Baits and Insecticides
Non-repellent insecticides and ant baits can effectively eliminate colonies.
Apply Natural Repellents
Diatomaceous earth, boric acid, and essential oils can deter ants naturally.
