The life cycle begins when an adult female lays eggs.
After hatching, tiny larvae immediately begin constructing protective cases.
For several weeks—or sometimes months depending on temperature and food—they continue feeding while enlarging their portable homes.
When fully developed, they attach the case to a stable surface such as a wall or ceiling.
Inside the case, they transform into pupae before eventually emerging as adult moths.
The adults mate, lay eggs, and begin the cycle again.
## Where Are They Most Common?
Household casebearers are commonly found in:
* Closets
* Bedrooms
* Hallways
* Bathrooms
* Laundry rooms
* Garages
* Basements
* Storage rooms
* Attics
You may also notice them attached to curtains, ceilings, baseboards, or even furniture.
## How Can You Tell if They're Active?
A case attached to the wall isn't necessarily occupied.
If the larva is alive, you may notice:
* Slight movement.
* The case changing position over time.
* A tiny head emerging from one end.
Empty cases often remain attached long after the adult moth has left.
## How to Remove Them
Fortunately, removing household casebearers is usually straightforward.
### Vacuum Regularly
Vacuum walls, ceilings, corners, closets, and baseboards.
Pay special attention to areas where dust and cobwebs collect.
### Remove Cobwebs
Since spider webs provide both food and construction material, removing them reduces available resources.
### Reduce Humidity
Use exhaust fans or dehumidifiers in damp rooms.
Proper ventilation makes the environment less favorable.
### Wash Natural Fabrics
Clean and properly store wool blankets, silk garments, and seasonal clothing.
Sealed plastic containers offer added protection.
### Inspect Storage Areas
Boxes, closets, and unused rooms should be cleaned periodically.
