How to Eliminate Woodworm: A Comprehensive Guide

Woodworm, also known as “carcoma” in Spanish, is a common problem that affects wooden structures and furniture. These tiny beetles and their larvae can cause significant damage if left untreated. In this article, we will explore effective methods to eliminate woodworm and protect your valuable wooden possessions.

Understanding Woodworm Infestation

Before we delve into the various methods of eliminating woodworm, it is essential to understand the nature of this infestation. Woodworm refers to the larvae of several species of beetles, including the common furniture beetle (Anobium punctatum) and the deathwatch beetle (Xestobium rufovillosum).

Woodworm infestation typically begins when adult beetles lay their eggs on the surface of untreated wood. Once the eggs hatch, the larvae burrow into the wood, feeding on its cellulose content. As they grow, the larvae create tunnels and chambers within the wood, weakening its structure and causing visible damage.

Woodworm infestation can go unnoticed for years, as the larvae remain hidden within the wood. However, signs of an infestation include small round exit holes, powdery frass (woodworm excrement), and weakened or crumbling wood.

Identifying the Type of Woodworm

Before proceeding with treatment, it is crucial to identify the specific type of woodworm infesting your wooden items. Different species of wood-boring beetles require different treatment methods. Here are some common types of woodworm:

  • Common Furniture Beetle (Anobium punctatum): This is the most common type of woodworm in Europe and is known for leaving small round exit holes (2-5mm in diameter) on the wood surface.
  • Deathwatch Beetle (Xestobium rufovillosum): This species is larger than the common furniture beetle and prefers hardwood. It creates larger exit holes (6-10mm in diameter) and is often associated with old, damp buildings.
  • Powderpost Beetle (Lyctus brunneus): These beetles infest hardwood and are commonly found in furniture and flooring. They leave small, round exit holes (1-2mm in diameter) and produce a fine, flour-like frass.

Identifying the specific type of woodworm will help you choose the most effective treatment method and ensure successful elimination.

Methods to Eliminate Woodworm

Now that we have a better understanding of woodworm infestation, let’s explore some effective methods to eliminate these pests:

1. Surface Treatment

Surface treatment involves applying a woodworm treatment product directly to the surface of the infested wood. This method is suitable for minor infestations and can help prevent further damage. Here’s how to carry out surface treatment:

  1. Thoroughly clean the wood surface, removing any dust, dirt, or loose wood fibers.
  2. Apply a woodworm treatment product, such as a spray or brush-on solution, following the manufacturer’s instructions.
  3. Allow the treatment to penetrate the wood and dry completely.
  4. If necessary, repeat the treatment after a few weeks to ensure complete eradication.

Surface treatment is most effective when combined with other methods, especially for severe infestations.

2. Injection Treatment

Injection treatment involves injecting a woodworm treatment product directly into the wood, targeting the larvae hidden within. This method is suitable for more severe infestations and provides deeper penetration. Here’s how to carry out injection treatment:

  1. Drill small holes into the infested wood, spacing them evenly.
  2. Inject the woodworm treatment product into the holes, ensuring it reaches the tunnels and chambers created by the larvae.
  3. Seal the holes with a suitable wood filler or putty.
  4. Allow the treatment to penetrate the wood and dry completely.
  5. Monitor the treated wood for any signs of reinfestation and repeat the treatment if necessary.

Injection treatment provides a more targeted approach and is often used in combination with surface treatment for optimal results.

3. Fumigation

Fumigation is a highly effective method for eliminating woodworm infestations in large or hard-to-reach areas. It involves using fumigants, such as methyl bromide or phosphine gas, to kill the larvae and adult beetles. Fumigation should only be carried out by trained professionals due to the potential health and safety risks involved.

During fumigation, the infested area is sealed off, and the fumigant is released to penetrate the wood and kill the woodworm. After a specified period, the area is ventilated to remove any remaining fumigant. Fumigation ensures complete eradication of woodworm but should be considered as a last resort due to its complexity and potential hazards.

Preventing Woodworm Infestation

Prevention is always better than cure when it comes to woodworm infestation. Here are some preventive measures you can take to protect your wooden items:

  • Ensure proper ventilation: Good airflow helps prevent dampness, which attracts wood-boring beetles. Use ventilation systems or open windows regularly to maintain dry conditions.
  • Keep humidity levels in check: Use dehumidifiers in areas prone to high humidity, such as basements or attics. Aim for humidity levels below 50% to discourage woodworm infestation.
  • Apply woodworm treatment: Treat wooden items with a suitable woodworm treatment product before they are exposed to potential infestation. This is especially important for untreated or newly acquired wood.
  • Regularly inspect wooden items: Routinely check your wooden furniture, flooring, and structural elements for signs of woodworm infestation. Early detection can prevent extensive damage.
  • Properly store and handle wood: Store wood in dry, well-ventilated areas and avoid stacking it directly on the ground. Additionally, inspect any second-hand wooden items before bringing them into your home.


Woodworm infestation can cause significant damage to wooden structures and furniture if left untreated. By understanding the nature of woodworm infestation and implementing effective treatment methods, you can eliminate these pests and protect your valuable wooden possessions.

Remember to identify the specific type of woodworm infesting your wooden items before choosing a treatment method. Surface treatment, injection treatment,
