As we dive into this comprehensive guide, we’ll explore what woodworms are, why they occur, and the essential steps to take if you want to treat and prevent woodworms in furniture.

What is a Woodworm?

The term “woodworm” might evoke images of worms munching through wood, but in reality, woodworm refers to the larvae of wood-boring beetles. These larvae feed on wood for nourishment, causing damage as they burrow and create tunnels. The result? Telltale tiny holes, often referred to as woodworm holes, mar the surface of your furniture.

Once these larvae mature, they transform into beetles, leave the wood, and lay eggs to continue the cycle. So, in essence, the real culprits causing the signs of woodworms in furniture are these tiny beetle larvae.

What Causes Woodworms to Appear?

Woodworms are attracted to humid environments, making damp wooden furniture a prime target. The moisture content in the wood, especially when it exceeds 15%, makes it highly susceptible to woodworm attacks. 

Factors like leaking roofs, inadequate ventilation, or rising dampness can increase moisture levels in the wood, inviting these pests. Remember, for woodworms in furniture, the environment is as vital as the wood itself.

Signs of Woodworm in Furniture

The first and most noticeable sign of woodworm in furniture is the appearance of small, round holes on the wood’s surface. These are the exit holes left by mature beetles. Moreover, you might also observe fine, powdery dust around these holes, known as frass. This frass is the waste produced by woodworms as they eat through the wood.

Another sign can be the visible weakening of wooden structures. For instance, chair legs might become wobbly, or the wood might sound hollow when tapped. Such signs indicate that the woodworm infestation has been active for a while.

How to Tell If a Woodworm is Active?

Fresh exit holes and the presence of frass are primary indicators of an active woodworm infestation. Additionally, during warmer months, you might spot adult beetles emerging from these holes or find them around windows. Remember, an absence of beetles doesn’t mean your furniture is free from woodworms, as the larvae can remain active underneath the surface.

What is the Difference Between Woodworms and Termites?

While both woodworms and termites are notorious for damaging wood, they are different creatures altogether. Termites are social insects that live in colonies and consume wood to feed their colony, causing significant structural damage.

 In contrast, woodworm refers to individual beetle larvae that eat wood as they grow, leaving behind filling woodworm holes.

How to Get Rid of Woodworm in the Furniture

The first step in woodworm treatment for furniture is to identify the extent of the infestation. If the furniture piece is severely damaged or the infestation is widespread, it’s wise to consult a pest control professional. For localized infestations, DIY treatments can be effective.

Home Remedies to Eradicate Woodworm

Fresh Acorns: Place fresh acorns in infested areas. These acorns attract mature beetles, diverting them from laying eggs in your furniture. Regularly replace the acorns to maintain their freshness.

Plastic Cover: Wrap the infested furniture piece in thick plastic and place it in direct sunlight. The heat will kill the woodworm. However, be cautious, as prolonged exposure might damage the furniture.

How to Protect Furniture from Woodworm

Regularly inspect your furniture for signs of woodworm in furniture. Ensure your home has proper ventilation to reduce dampness. Additionally, consider using wood preservatives, especially when acquiring second-hand furniture. Before filling woodworm holes, ensure that you’ve successfully treated the woodworm infestation.

DIY Woodworm Treatment

For those who want to tackle the problem head-on, DIY woodworm treatment for furniture involves applying chemicals like boron and permethrin. Ensure you wear gloves and a mask and work in a well-ventilated area. Fill the woodworm holes after the treatment to restore the furniture’s appearance.
