What Are Plaster Bagworms?

Plaster bagworms are the larval stage of a specific type of moth. While there are over 1,000 species of bagworms in the U.S., the one that causes the most grief in Florida is—you guessed it—the plaster bagworm. These little guys love humidity (welcome to Florida!) and are most commonly found in garages, bathrooms, and other slightly sheltered, humid areas.

How to Identify a Bagworm Infestation

You might not know what a bagworm is, but if you’ve seen tiny, oval-shaped, grayish cocoons clinging stubbornly to your walls, you’ve met their handiwork. Common signs of a bagworm problem include:

  • Small, silk-covered cases attached to walls, ceilings, or under eaves
  • Sudden appearances of moths in your home (these are the adult bagworms)

What Attracts Bagworms to Your Home?

Plaster bagworms are lazy little decorators, making their homes out of spider silk and debris. They primarily feed on spider webs, but when those aren’t available, they’ll settle for lint and dust. So, if your garage or bathroom is doubling as a spider Airbnb, bagworms are moving in right behind them.

But what brings them to your house in the first place? The answer: lights left on overnight. Moths are drawn to light like Floridians to the beach in winter, and since adult bagworms are moths, they’ll happily flutter toward any outdoor lighting. This means turning off unnecessary lights at night can significantly reduce the number of bagworms (and other bugs) attracted to your home.

How to Get Rid of Plaster Bagworms

If you’ve got a bagworm problem, don’t worry—there are solutions.

Here’s how you can tackle it:

  1. Remove Their Food Source – Since they love to snack on spiderwebs, lint, and dust, keeping your home clean is the first step. Regularly dusting, vacuuming, and removing spider webs will make your home less appealing to them. (Good news: with our regular pest control service, we remove spider webs from your home, which also helps control spiders and mud daubers!)
  2. Reduce Humidity – Plaster bagworms thrive in humid environments. Using a dehumidifier in your garage, bathroom, or other bagworm infested areas will dry them out and make your home inhospitable to them. A simple fix that works wonders!
  3. Seal Entry Points – These little freeloaders often sneak in under garage doors. If your garage door seal is worn out, replacing it might be all you need to stop them from getting inside. Also, check for small cracks and gaps around your home and seal them up.
  4. Turn Off Exterior Lights at Night – Since adult bagworms are moths, keeping outside lights off unless necessary can prevent them from coming around in the first place. Less light = fewer moths = fewer bagworms.
  5. Pesticide Treatments – If you want immediate results, we can treat the affected areas with pesticide, which is highly effective at killing them. However, be prepared—dead bagworms don’t just disappear. They stick to walls like a bad decision, and you’ll likely have to pull them off manually.

The Final Cleanup: Dealing with Dead Bagworms

Even after you’ve won the battle, you may still have the aftermath to deal with—those stubborn little cases clinging to your walls. Because bagworms move slowly (if at all), it can be hard to tell which ones are alive and which are just decorative remnants. Either way, you’ll need to physically remove them, as they won’t just fall off on their own.

Plaster Bagworms FAQ’s

Plaster bagworms are the larvae of moths that create small, grayish silk bags to live in. They thrive in humid environments and often appear in garages, bathrooms, or under eaves. Unlike other bagworms that eat tree leaves, plaster bagworms feed on spider webs, lint, and dust.

Common signs of a plaster bagworm problem include:


✔️ Small hanging or attached silk bags on walls, ceilings, or garage doors.
✔️ Dead bagworms stuck to the walls that need to be scraped off.
✔️ An increase in spider webs around your home (their main food source).
✔️ Moths gathering around your outdoor lights at night—they lay the eggs that turn into bagworms.

Bagworms are drawn to your home because of:

  • Spider webs (their primary food source).
  • High humidity, especially in garages and bathrooms.
  • Outdoor lights at night, which attract moths that lay eggs.
  • Small cracks or openings around your home, especially under garage doors.

1️⃣ Remove spider webs and dust (their food source).
2️⃣ Use a dehumidifier to dry out the area and make it inhospitable.
3️⃣ Seal cracks and replace worn-out garage door seals to keep them out.
4️⃣ Turn off outdoor lights at night to stop attracting moths.
5️⃣ Use professional pest control treatments, which are highly effective at killing bagworms.

Yes! Pesticide treatments are very effective at killing bagworms, but dead bagworms remain stuck to the walls. After treatment, they often need to be manually removed.

Even after dying, bagworms remain glued to surfaces because their silk bags are attached with strong webbing. The only way to remove them is by scraping them off manually.

Yes, if the conditions remain favorable. To prevent bagworms from returning, you should:


✔️ Eliminate spider webs and dust regularly.
✔️ Reduce humidity with a dehumidifier.
✔️ Seal entry points, especially in garages.
✔️ Turn off outdoor lights at night to prevent moths from laying eggs.
✔️ Schedule regular pest control treatments.

Plaster bagworms don’t damage wood or fabric, but they are unsightly and can be a nuisance. They primarily feed on spider webs, lint, and dust. Unlike other bagworm species, plaster bagworms do not harm plants or trees.

Yes, you can scrape off dead bagworms manually. However, if you don’t fix the underlying issues (spider webs, humidity, and cracks), they’ll keep coming back. Professional pest control helps eliminate them long-term.
