Although bagworms are not aquatic insects, they are drawn to moisture. Bathrooms and laundry rooms provide humidity, warmth, and lint—all conditions that support their survival. They may hide near ventilation fans, behind washing machines, or along bathroom walls where moisture is present but disturbance is minimal.
