Types of Woodworms

Common Furniture Beetle (Anobium punctatum)

The common furniture beetle, also known as Anobium punctatum, is one of the most widespread wood-boring pests. These beetles typically infest softwoods such as pine, spruce, and cedar. They lay their eggs in cracks and crevices of the wood, and the larvae feed on the wood fibers, causing damage over time.

Deathwatch Beetle (Xestobium rufuvillosum)

The deathwatch beetle, scientifically known as Xestobium rufuvillosum, is a larger species of wood-boring beetle. These beetles infest hardwoods, especially oak, and are commonly found in older, damp buildings. They create a tapping sound, known as “deathwatch,” which they use to attract mates.

House Longhorn Beetle (Hylotrupes bajulus)

The house longhorn beetle, or Hylotrupes bajulus, is recognized for its long antennae. This wood-boring beetle targets softwoods, particularly timber used in construction. Infestations by house longhorn beetles can lead to structural damage and weaken the wooden elements in a building.

Powderpost Beetles (Lyctinae)

Powderpost beetles, belonging to the family Lyctinae, are a group of wood-boring insects known for the fine and powdery frass they produce. These beetles attack both hardwoods and softwoods, and their larvae tunnel into the wood, leaving behind small holes and frass.

Wood Borer Weevils (Pentarthrum huttoni)

Wood borer weevils, scientifically referred to as Pentarthrum huttoni, are a type of beetle commonly found in New Zealand. They primarily infest native and exotic hardwoods. The larvae of these weevils bore into the wood, causing damage to furniture, flooring, and other wooden structures.

Wood Weevils (Euophryum confine)

Wood weevils, also known as Euophryum confine, are another species of weevils that can cause damage to wooden structures. These beetles primarily infest softwoods and are known for their long snouts. Wood weevil larvae create tunnels in the wood, leading to weakened structures.

False Powderpost Beetles (Bostrichidae)

False powderpost beetles, belonging to the family Bostrichidae, are a group of wood-boring insects that resemble powderpost beetles. These beetles attack both hardwoods and softwoods. False powderpost beetles are often found in wooden furniture and can cause significant damage if left untreated.

Wood Wasps (Urocerus gigas)

Wood wasps, or Urocerus gigas, are not actually worms but are often mistaken for them due to their slender bodies. These insects have long ovipositors used for drilling into wood and laying eggs. Wood wasp larvae feed on the wood, leaving behind tunnels and causing damage to wooden structures.

Wood Termites (Reticulitermes flavipes)

Wood termites, scientifically known as Reticulitermes flavipes, are social insects that feed on cellulose-rich materials, including wood. They are particularly destructive and can cause extensive damage to buildings if left untreated. Termite infestations require immediate attention from professionals.

Old House Borer (Hylotrupes bajulus)

The old house borer, also known as Hylotrupes bajulus, is similar to the house longhorn beetle in terms of its damage-causing abilities. However, it primarily infests softwood, including structural beams, flooring, and furniture. Infestations by old house borers can compromise the structural integrity of the affected wood.

Life Cycle of Woodworms

Egg Stage

The life cycle of woodworms begins with the eggs laid by adult beetles. Female beetles typically lay their eggs in cracks, crevices, or existing exit holes in the wood. The exact number of eggs laid depends on the species, but it can range from a few to several hundred. The eggs are too small to be visible to the naked eye.

Larval Stage

Once the eggs hatch, the woodworms enter the larval stage. During this stage, the larvae actively feed on the wood, tunneling through it and breaking down the cellulose fibers. This is the most destructive stage, as it causes the majority of the structural damage. The larvae generally remain in the wood for several months to several years, depending on the species and environmental conditions.

Pupal Stage

After completing their feeding, the larvae enter the pupal stage. During this stage, the larvae transform into pupae, developing into their adult form. The pupal stage typically occurs inside the wood, within a pupal chamber constructed by the larvae. The duration of the pupal stage varies depending on the species and environmental conditions.

Adult Stage

Once development is complete, the adult woodworms emerge from the wood through exit holes. The timing of their emergence is often influenced by environmental factors such as temperature and humidity. Adult woodworms have wings and are capable of flying to find mates and suitable places to lay their eggs. The adult stage is relatively short-lived, usually lasting only a few weeks.

Signs of Woodworm Infestation

Small Holes and Tunnels in Wood

One of the most common signs of a woodworm infestation is the presence of small holes in the wooden surfaces. These holes are typically round and can vary in size, depending on the species of woodworm. The entrance holes are where the adult beetles emerged from the wood, while the tunnels are created by the larvae as they feed.

Fine Sawdust or Frass

Another clear indicator of a woodworm infestation is the presence of fine sawdust or frass around the wooden items or furniture. This sawdust is the result of the woodworm larvae burrowing through the wood and pushing out the digested wood fibers. The frass can often be found beneath and around the exit holes.

Crumbly or Damaged Wood Surface

Woodworm infestations can lead to the deterioration of the wooden surface. The constant feeding and tunneling by the larvae can weaken the wood, causing it to become crumbly or damaged. If you notice any areas of wood that appear weakened or crumbling, it could be a sign of a woodworm infestation.

Weak or Hollow Sound When Tapping on Wood

When you tap on wood affected by woodworms, you may notice a weak or hollow sound. This is because the larvae have hollowed out tunnels within the wood, reducing its density. If you suspect a woodworm infestation, try tapping on various sections of the wooden item and listen for any variations in sound.

Presence of Adult Beetles

If you observe adult beetles emerging from the wood or notice them flying around your home, it is a strong indication of a woodworm infestation. Adult beetles typically emerge during the warmer months, and their presence suggests that there are eggs, larvae, or pupae hidden within the wood.

Causes of Woodworm Infestation

Moisture and Dampness

Woodworms thrive in moist conditions, making moisture and dampness a leading cause of infestations. Excessive humidity, leaks, or poor ventilation can create the perfect environment for woodworms to breed and flourish. It’s important to address any moisture issues and maintain proper humidity levels to prevent infestations.

Poor Ventilation

Inadequate ventilation can contribute to the buildup of moisture, which attracts woodworms. Without proper airflow, wooden surfaces may remain damp for extended periods, providing an ideal habitat for wood-boring insects. Ensuring good ventilation in your home helps reduce the risk of woodworm infestations.

Wooden Structures in Contact with Soil

When wooden structures, such as posts or support beams, come into contact with soil, there is an increased risk of woodworm infestations. Moisture from the soil can seep into the wood, creating a damp environment that attracts wood-boring insects. To prevent infestations, it’s essential to elevate wooden structures and maintain a gap between wood and soil.

Presence of Infested Furniture or Wood

If you introduce infested furniture or untreated wood into your home, you may unknowingly be welcoming woodworms. Second-hand furniture or wooden items acquired from infested sources can bring wood-boring insects into your living space. Always inspect and treat any used wooden items before bringing them indoors.

Prevention of Woodworm Infestation

Maintaining Proper Moisture Levels

Controlling moisture and dampness is crucial in preventing woodworm infestations. Ensure that your home has proper insulation and address any leaks or areas of excessive moisture.
