Plaster bagworms, also known as household casebearers, are a type of moth that is commonly found in homes, particularly in humid and warm climates. They are typically small, measuring less than half an inch in length, and are identifiable by their grayish-brown color and the hard bag that they construct around themselves.

What Do They Eat?

Plaster bagworms feed on a variety of organic matter, including dead insects, spiders, and even other bagworms. They are also known to feed on fabrics and paper products, such as books and wallpaper.

What Are the Sign of Their Presence?

The signs of plaster bagworm infestation usually become evident when they have created their protective bags in hidden places, such as corners, ceilings, and walls. You may also notice small holes that the bagworms have created while feeding.

Preventive Measures

Preventing Plaster Bagworms

The best way to get rid of plaster bagworms is to prevent them from entering your home in the first place. Here are some preventive measures that you can take:

  • Seal all cracks and crevices in your walls, ceilings, and floors to prevent entry.
  • Store clothes in plastic bins or vacuum-sealed bags to prevent bagworms from eating them.
  • Dispose of dead insects and spiders quickly to prevent the bagworms from feeding on them.

Eliminating Plaster Bagworms Naturally

Natural Plaster Bagworm Removal

If you have already identified a plaster bagworm infestation in your home, there are natural remedies that you can use to get rid of them. Here are some ways to eliminate plaster bagworms naturally:

1. Sticky Traps

Plaster bagworms are attracted to light, and they are known to get stuck on sticky traps designed to capture flying insects. Place these traps near windows and other areas where the bagworms are known to congregate.

2. Vacuum Cleaner

One of the most effective ways to remove bagworms is to use a vacuum cleaner. Make sure that you reach all the hidden corners, ceilings, and walls where the bagworms are likely to be hiding. Dispose of the vacuum bag afterward to prevent the bagworms from escaping.

3. Diatomaceous Earth

Diatomaceous earth is a natural product that is effective in killing plaster bagworms. This fine powder cuts through the exoskeleton of the bagworms, dehydrating and killing them. Sprinkle it around the areas where the bagworms are commonly found.

4. Essential Oils

Essential oils, including lavender, peppermint, and cedar, are effective in repelling plaster bagworms. Place a few drops of the oil on cotton balls and place them in areas where the bagworms congregate.
