Always check the walls of your house regularly for these insects..

Are They Dangerous?

The short answer is no, they won't hurt you or your pets—they don't bite, sting, or carry diseases. However, they aren't entirely benign houseguests.

If left unchecked, an army of household casebearers can do real damage to your belongings. While they usually prefer dust and spider webs, they will gladly eat natural, organic fibers. Your wool rugs, silk curtains, upholstered furniture, and cherished clothing items can quickly become an expensive snack for these crawling larvae.

How to Evict Plaster Bagworms

If you notice cases like the ones pictured dotting your home, getting rid of them requires a thorough but simple strategy:

Suck Them Up: The fastest way to deal with visible cases is to vacuum them straight off the walls and ceilings. Be sure to empty your vacuum canister or bag immediately into an outside trash bin so they don't simply crawl back out.
Clear the Cobwebs: Strip away their primary food source. Regularly dust and vacuum away spiderwebs, corners, and hidden pockets behind furniture.
Drop the Humidity: Because these pests adore moisture, running a dehumidifier or keeping your air conditioner active can make your home far less attractive to them.
Seal the Gaps: Ensure your window screens are intact to prevent adult moths from flying inside and laying up to 200 eggs at a time.
