Top Woodworm Treatment Methods for Hampshire Residents

Woodworm infestations can wreak havoc on wooden structures and furniture, leading to significant damage and costly repairs if not addressed promptly. Hampshire residents, in particular, need to be vigilant due to the region’s humid climate, which can exacerbate woodworm problems. This comprehensive guide explores the top Woodworm Treatment Hampshire methods, helping homeowners protect their properties effectively.

Understanding Woodworm

What Is Woodworm?

Woodworm refers to the larvae of various wood-boring beetles that infest and feed on wood. The most common species in the UK include:

  • Common Furniture Beetle (Anobium punctatum): Targets both softwoods and hardwoods, leaving small round exit holes.
  • Deathwatch Beetle (Xestobium rufovillosum): Typically infests hardwoods, especially in older, damp buildings.
  • House Longhorn Beetle (Hylotrupes bajulus): Prefers softwoods and can cause severe structural damage.
  • Powderpost Beetle (Lyctus brunneus): Infests hardwoods with high starch content, such as oak and ash.

Lifecycle of Woodworm

The lifecycle of woodworm includes four stages:

  1. Egg: Adult beetles lay eggs on or just below the surface of the wood.
  2. Larva: Larvae hatch from the eggs and burrow into the wood, creating tunnels as they feed.
  3. Pupa: After several years of feeding, the larvae pupate near the surface of the wood.
  4. Adult Beetle: Adult beetles emerge from the wood, leaving characteristic exit holes, and the cycle begins anew.

Identifying Woodworm Infestation

Signs of Woodworm Infestation

Exit Holes

Small, round holes (approximately 1-2mm in diameter) on the surface of the wood indicate where adult beetles have emerged.

Bore Dust (Frass)

A fine, powdery dust (frass) found around exit holes is produced by the larvae as they tunnel through the wood.

Damaged Wood

Infested wood may feel weak and crumbly. Crumbling edges, cracks, and splitting can also indicate woodworm activity.

Live Beetles

Finding live beetles around your home, especially near wooden structures, suggests an active infestation.

Tunnels in Wood

Cutting into the wood and finding tunnels or galleries is a clear sign of woodworm activity.

Tools for Inspection

Visual Inspection

A thorough visual inspection can help identify signs of woodworm, such as exit holes, frass, and damaged wood.

Moisture Meter

Woodworm thrives in damp conditions. Using a moisture meter to detect high moisture levels in wood can help identify areas at risk.


A borescope allows you to inspect inside walls and other hard-to-reach areas for signs of woodworm activity.

Top Woodworm Treatment Methods

Chemical Treatments


Insecticides are a common and effective method for treating woodworm infestations. These chemicals penetrate the wood and kill larvae within the tunnels.

How to Apply Insecticides
  1. Preparation: Ensure the area is well-ventilated and clear of furniture and personal items.
  2. Application: Apply the insecticide using a brush, spray, or injection method, following the manufacturer’s instructions.
  3. Safety: Wear protective clothing, gloves, and a mask to avoid contact with the chemicals.

Boron Treatments

Boron-based treatments are effective against woodworm and are less toxic to humans and pets compared to traditional insecticides. They can be applied as a paste or liquid.

How to Apply Boron Treatments
  1. Preparation: Clean the affected wood and ensure it is dry.
  2. Application: Apply the boron treatment using a brush or sprayer, ensuring thorough coverage.
  3. Drying: Allow the treatment to dry completely, which may take several days depending on the product.

Non-Chemical Treatments

Heat Treatment

Heat treatment involves raising the temperature of the affected wood to a level that is lethal to the larvae. This method is chemical-free and effective for large-scale infestations.

How Heat Treatment Works
  1. Preparation: Clear the area of furniture and personal items.
  2. Equipment: Professional equipment is used to raise the temperature of the wood to around 55-60°C (131-140°F).
  3. Duration: Maintain the temperature for several hours to ensure all larvae and eggs are killed.


Freezing is an effective treatment for smaller items or furniture. Exposing the wood to sub-zero temperatures for an extended period can kill the larvae and prevent further damage.

How to Freeze Woodworm-Infested Items
  1. Preparation: Wrap the infested item in plastic to prevent moisture damage.
  2. Freezing: Place the item in a commercial freezer or use a professional service. Maintain the temperature below -18°C (0°F) for at least 2-3 weeks.
  3. Thawing: Gradually thaw the item to prevent condensation and moisture damage.

Professional Services

Pest Control Experts

Professional pest control services have the expertise and equipment to effectively assess and treat woodworm infestations. They can provide comprehensive solutions, including chemical and non-chemical treatments.

Benefits of Professional Pest Control
  • Expertise: Professionals have extensive knowledge of woodworm species and effective treatment methods.
  • Equipment: Access to specialized equipment for thorough treatment.
  • Safety: Professionals ensure the safe application of treatments, protecting residents and pets.

Structural Repairs

In cases of severe damage, structural repairs may be necessary to restore the integrity of the affected wood. This may involve replacing damaged beams or reinforcing weakened structures.

How Structural Repairs Are Conducted
  1. Assessment: A professional assesses the extent of the damage.
  2. Repair Plan: Develop a repair plan, which may include replacing or reinforcing affected wood.
  3. Execution: Carry out the repairs, ensuring the structural integrity of the building is restored.

Preventive Measures

Reducing Moisture Levels


Ensure proper ventilation in your home to reduce moisture levels. Use dehumidifiers in damp areas and maintain good airflow.


Proper drainage around the property can prevent water from seeping into wooden structures. Ensure gutters and downspouts are functioning correctly.

Regular Inspections

Conduct regular inspections of wooden structures and furniture for signs of woodworm. Early detection can prevent severe damage and make treatment more effective.

Treating Wood


Applying wood preservatives can help deter beetles from laying eggs and larvae from burrowing. Reapply treatments as recommended by the manufacturer.

Varnishes and Paints

Coating wood with varnishes or paints can provide a protective barrier against woodworm. Ensure that all surfaces are thoroughly covered.
