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: Fuzzy larvae or shed skins near fabrics
- Track whether this clue persists, returns, or spreads: Irregular holes in wool, silk, feathers, or felt
- Track whether this clue persists, returns, or spreads: Adults at windows or light sources
- Track whether this clue persists, returns, or spreads: Activity under furniture, along edges, or in vents
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
- Store wool and natural fibers in sealed containers.
- Clean pet hair and lint from edges and vents.
- Inspect stored seasonal clothing before long-term storage.
- Use monitoring traps in closets and storage rooms.
When to call a professional
Call a professional when larvae are widespread, valuable textiles are affected, or the source is hidden in wall voids or vents.
Safety notes
- Confirm the pest or evidence before applying a control product.
