The fastest useful split
Drywood termite pellets are uniform and hard; carpenter-ant debris is mixed and fibrous, often with insect fragments.
Do not rely on a single color match. Start with scale and physical form, then check where the sign accumulates and whether a companion clue supports one candidate over the other.
| Feature | Drywood termite | Carpenter ant |
|---|---|---|
| Texture | Uniform hard pellets | Mixed fibers and chips |
| Shape | Consistent faceted grains | Irregular shavings |
| Opening | Tiny kick-out hole | Slit or gallery crack |
| Companion clue | Equal wings/pellets | Large ants/moist wood |
Magnify a detached sample and compare uniformity before disturbing wood.
Fresh structural evidence deserves professional inspection.

Drywood termite
Kalotermitidae
Uniform hard pellets in small piles directly below tiny wood openings, often recurring after cleanup.
Carpenter ant
Camponotus spp.
Coarse mixed wood shavings below a slit or crack, often with large ants and moisture-damaged wood nearby.
Why a visual match can fail
Scale can be distorted by a close-up photograph, loose material may be moved by cleaning or airflow, and old evidence can change color or texture. A reliable conclusion uses multiple observations that point in the same direction and preserves contradictory details instead of forcing a match.
