Cocoon on Wall | How to Get Rid of Plaster Bagworms

The cocoons you see on your walls or ceilings are called Plaster Bagworms. Commonly referred to as the "household casebearer", it is one of these pests that can be a major annoyance to homeowners. These small cocoons spin protective cases around debris, and can infest a home if left unchecked. This article will provide guidance on how to effectively remove plaster bagworms from Singapore and how to avoid further infestations in the future.

What are Plaster Bagworms?

Plaster bagworms (Phereoeca uterella) are small, moth-like insects commonly found in homes across Singapore. They are known for their distinct behavior of constructing protective cases from silk and debris such as dust, lint, and small particles of plaster. These cases serve as a shield against predators and harsh environmental conditions. Bagworm larvae, often mistaken for caterpillars, remain inside these cases, sticking them to walls, ceilings, and various surfaces.

While plaster bagworms are not directly harmful to humans, they can become a nuisance and a potential threat to your property. Large populations of bagworms can cause damage to plaster and stucco walls, leaving unsightly marks on surfaces. Furthermore, their presence can trigger allergies in some individuals.

How to Get Rid of Plaster Bagworms

Now, let's delve into effective methods to get rid of plaster bagworms in Singapore.

Regular Cleaning and Vacuuming

Prevention is the first line of defense against plaster bagworms. Regularly clean and vacuum your home to remove dust, lint, and debris, which are primary components of the bagworms' protective cases. Pay special attention to corners, walls, and ceilings.

Remove Existing Cases

To get rid of existing plaster bagworms, carefully remove their cases by hand or using a soft brush. Be gentle to avoid damaging your walls or ceilings. Dispose of the cases in a sealed plastic bag to prevent reinfestation.

Maintain Proper Lighting

Plaster bagworms are attracted to dark, undisturbed areas. Maintain proper lighting in your home to discourage their presence. Use LED lights with warm colors, as these are less attractive to moths.

Seal Cracks and Openings

Inspect your home for cracks, crevices, and openings that can serve as entry points for plaster bagworms. Seal these gaps with caulk or other suitable materials to prevent their entry.

Reduce Humidity

Bagworms thrive in humid conditions. Considering Singapore's hot and humid climate, use dehumidifiers or air conditioners to reduce indoor humidity levels, making your home less hospitable to these pests.

Natural Predators

Consider introducing natural predators of bagworms, such as parasitic wasps or spiders, into your home. These predators can help keep the bagworm population in check.


As a last resort, you can use insecticides specifically designed for bagworm control. Be sure to follow the manufacturer's instructions and take appropriate safety precautions when using chemicals in your home. Insecticides should only be used if other methods have proven ineffective.

Consult Pest Professionals

If you find yourself dealing with a severe infestation that you cannot control on your own, it's best to consult professional pest control services in Singapore. They have the expertise and tools to effectively eradicate plaster bagworms from your home.

Plaster bagworms may be a common nuisance in Singapore, but with the right preventive measures and treatment methods, you can keep your home bagworm-free. Regular cleaning, sealing cracks, and maintaining proper lighting are essential steps to deter these pests.
