When you discover wood damage in or around your home, there may be a few questions that run through your mind.
Is the damage new or has it been there for a while?
How far does the damage go?
Is my home structurally compromised?
Can this wood be repaired, or does it need full replacement?
Is this covered by homeowner's insurance?
But one of the most important questions shouldn't be overlooked: What caused the damage?
Carpenter ants and termites are among the most common culprits of wood damage. And knowing the difference is crucial, because if your wood damage is caused by pests, you want to make sure the treatment fits the infestation.
At Guard Pest Control, we help homeowners across Washington accurately identify and eliminate wood-destroying insects using our proven Inspect, Correct, Protect approach.
Why It's Important to Know the Difference
Carpenter ants and termites are often confused because:
Both damage wood
Both swarm in the spring
Both can be found inside walls or structural beams
But they are different. For example, while termites eat wood, carpenter ants only excavate wood to build their nests.
Physical Differences
Body Shape
Carpenter Ants
Narrow, pinched waist
Distinct, segmented body
Elbowed antennae
Termites
Straight, uniform body (no narrow waist)
Straight antennae
Softer, pale, or creamy-colored appearance
Wings (When Swarming)
Both pests produce winged swarmers, especially in spring.
Carpenter Ant Swarmers
Front wings longer than back wings
Dark-colored bodies
Termite Swarmers
Two pairs of wings equal in size
Wings extend well past the body
Often lighter in color
Differences in Wood Damage
Carpenter Ant Damage
Smooth, clean tunnels inside wood
Wood looks hollowed out or sanded
Often accompanied by small piles of sawdust-like material (called frass)
Termite Damage
Rough, mud-lined tunnels
Wood may look layered or honeycombed
Mud tubes along foundation walls or crawlspaces
Termites consume wood from the inside out, often leaving the outer surface intact while structural damage progresses unseen.
Behavior Differences
Carpenter Ants
Prefer moist, damaged, or decaying wood
Do not eat wood
May be seen foraging, especially at night
Typically nest in wall voids, insulation, or damp structural wood
Termites
Eat wood and other cellulose materials
Can infest dry, sound wood (depending on species)
Live in large underground colonies
Rarely seen outside of swarm season
Build mud tubes to travel between soil and food sources
Active 24/7 inside structures
Which Is More Dangerous?
Both can cause significant structural damage over time, but termites typically cause more severe, long-term structural damage because they eat wood continuously. Carpenter ants infestations can still weaken structural elements, especially when moisture issues are present.
The sooner the infestation is identified, the less costly the repairs will be.
Common Signs You May Have a Problem
Hollow-sounding wood
Bubbling paint or warped surfaces
Small piles of sawdust
Mud tubes along your foundation
Swarming insects indoors
Shed wings near windows
If you're unsure what you're seeing, professional identification is the safest option.
