Wood Worm

Woodworms are the larvae of various wood-boring beetles. These larvae feed on wood, causing damage to wooden structures and furniture over time.

Impact of Woodworm Infestations

Structural Damage:
Woodworm infestations can weaken timber, particularly at bearing ends, where damage may not be immediately visible.

Long-Term Consequences:
If left untreated, woodworm activity can compromise the structural integrity of a property, making early detection and intervention crucial.

Assessment Techniques

At Olympic Surveyors, our specialist timber surveyors use a range of methods to determine whether an infestation is active and to assess the damage:

Visual Inspection:

Look for small, round exit holes from emerging beetles.

Identify fine, powdery dust (frass) around these holes, indicating active larvae.

Examine the overall condition of the wood for signs of weakening or hollowing.

Sound Testing:

Experienced surveyors listen for differences in the timber to pinpoint areas where larvae have created tunnels.

Resistance Drilling:

Utilising high-speed needle drills (1.5 to 5.0 mm diameter), we measure drilling resistance to detect decay, cracks, and hidden damage.

Results are presented graphically to show timber hardness and the extent of infestation.

Frass Analysis:

Examining the characteristics of the dust helps identify the beetle species and confirm whether the infestation is active.

Environmental Assessment:

Evaluating factors such as moisture ingress, high humidity, and poor ventilation, which can contribute to woodworm activity.

Professional Expertise:

Relying on extensive knowledge of woodworm species, their behaviour, and damage patterns to provide an informed assessment.

Common Woodworm Species and Lifecycle

Types of Woodworms:

Common Furniture Beetle (Anobium punctatum):

Appearance: Small, reddish-brown beetle

Damage: Creates small round exit holes in wood.

House Longhorn Beetle (Hylotrupes bajulus):

Appearance: Larger beetle with long antennae

Damage: Causes extensive damage to structural timber.

Deathwatch Beetle (Xestobium rufovillosum):

Appearance: Small, distinctive reddish-brown beetle

Damage: Significant damage in older buildings.

Powderpost Beetle (Lyctus spp.):

Appearance: Small, powdery beetle

Damage: Leaves a powdery residue and small holes in wood.

Lifecycle Stages:

Eggs: Laid in cracks or crevices in the wood.

Larvae: Hatch and burrow into the wood, creating tunnels and feeding on the timber.

Pupae: Develop inside the wood.

Adults: Emerge from the wood, leaving behind characteristic exit holes.

Signs of Woodworm Infestation

Small Holes:
Tiny, round exit holes on the wood surface.

Powdery Dust:
Fine frass accumulating around the exit holes.

Tunnelling:
Hollowed-out areas in the wood caused by larval feeding.
