Don't confuse frass with sawdust
TL;DR: Frass = pellets with 6 concave sides. Sawdust = irregular shavings. Use checklist to identify, log LTRS if frass.
Quick comparison checklist
| Feature | Termite Frass | Sawdust |
|---|---|---|
| Shape | Uniform pellets, ~1mm long | Irregular shavings, chips |
| Sides | 6 concave sides (hexagonal) | No defined sides |
| Consistency | Hard, dry, like sand | Soft, fibrous, fluffy |
| Source | Pushed out of kick-out holes | Falls during cutting/boring |
| Pattern | Neat piles, recurs after cleanup | Scattered, doesn't recur |
What to do
- If pellets: Log LTRS (location, timing, recurrence), look for kick-out holes above pile.
- If shavings: Check for carpenter ants, powder post beetles, or recent woodwork—not drywood termites.
- When unsure: Request inspection or call (833) 404-3632—only professionals can confirm species.
Quick answers
- What if it's somewhere in between?
- If unsure, treat as potential frass. Log the pattern with LTRS and schedule an inspection—only professionals can confirm.
- Can sawdust turn into frass over time?
- No, they're fundamentally different. Frass is termite feces; sawdust is wood particles from cutting or boring.
