How to judge progress
Recheck the same locations and evidence types instead of judging the result from one quiet interval.
- Track whether this clue persists, returns, or spreads: Irregular holes in wool, cashmere, silk, or fur
- Track whether this clue persists, returns, or spreads: Webbing or cases on fabric surfaces
- Track whether this clue persists, returns, or spreads: Small moths flying weakly in closets
- Track whether this clue persists, returns, or spreads: Larvae or gritty debris in stored textiles
Signs the treatment is not working
- Fresh evidence continues to appear in the same inspected locations.
- Activity spreads to new rooms, materials, or monitoring points.
- The suspected source remains active after the action plan has been followed and reassessed.
After treatment and reducing recurrence
- Clean clothing before long-term storage.
- Use sealed garment bags or bins for valuable wool and silk.
- Inspect stored items every season.
- Reduce dust, hair, and lint in closets.
When to call a professional
