Woodworm beetles

While inside the log, the woodworm evolves and gnaws on the starch-containing part of the log. It is detected when mature imago beetles appear, leaving holes and wood powder piles. The woodworm hole diameters vary from 0.7 to 3.2 millimetres, depending on the species. Once the females lay the eggs, they re-infest the wood, proceeding with this cycle for several generations until they consume all the wood. However, trees can be naturally immune, which manifests in very low starch content.

Cerambycidae, also known as the Longhorn beetle, represents a very big family of beetles featuring extremely long whiskers that are longer than a maturing insect's body. There is also one curious fact: the scientific name is based on Greek mythology. After a dispute with the nymphs, the shepherd Kerambos was turned into a big bug with big horns and whiskers.
These insects live and reproduce in wood, and their larvae feed on wood fibers. Some species of longhorn beetles are particularly harmful to wooden buildings, furniture, and other wooden structures.

Harm to Wooden Houses
The primary wood-damaging longhorn beetle is the house longhorn beetle (Hylotrupes bajulus). Here's how it harms wooden homes:
Wood destruction:

• The beetle larvae burrow into wood, creating long tunnels. These damages weaken the wood, which can lead to the structural weakening or even collapse of key parts of the house, such as beams, walls, or floors.

Invisible damage:

• The larvae often work inside the wood, so external signs of damage may not be visible until the structure is significantly weakened. This increases the risk of sudden breakages.

Impact on the house’s stability:

• Damaged wooden structures lose their strength, which can result in deformations, cracks, or even the collapse of parts of the building.

Decreased house value:

• Beetle-damaged wood not only affects the appearance of the building but also reduces its market value. Repairing or replacing damaged elements can be costly and labor-intensive.

To protect wooden buildings from longhorn beetles, preventive measures such as treating wood with special antiseptic agents or using thermally treated wood are recommended.

Xestobium rufovillosum - Deathwatch beetle. The adult insect is 7 millimetres long, and the larvae are up to 11 millimetres. They make poking sounds that come from rafters and beams in calm weather. These woodboring beetles are usually associated with a clock that's counting down to death. Indeed, the sound is very disturbing. They digest cellulose with their enzymes, assuming that preliminary fungal decomposition has already occurred.

Xestobium rufovillosum, commonly known as the deathwatch beetle, is a wood-boring beetle from the family Anobiidae. It is notorious for infesting and damaging old hardwood, particularly in buildings and furniture. The larvae of this beetle feed on decaying or seasoned wood, especially oak, but they can also target other types such as ash, beech, and conifers.

One of the beetle's distinctive behaviors is its tapping or "ticking" sound made by adult beetles to attract mates. This sound, often heard in old wooden structures, gives the beetle its name "deathwatch," as it was historically associated with quiet, somber moments, like death vigils.

The damage caused by Xestobium rufovillosum can be extensive because the larvae bore into the wood, weakening it over several years, sometimes without visible signs until the structure's integrity is compromised.

is also a wood pest from the Anobiidae family

The main differences between the furniture beetle (Anobium punctatum) and the deathwatch beetle (Xestobium rufovillosum):
Type of wood they infest:

• Furniture beetle: Primarily infests softwood species, such as pine, spruce, and fir. It is most commonly found in furniture, parquet, and other wooden structures.
• Deathwatch beetle: Mainly infests hardwood species, especially oak, although it can also attack other old wooden structures, such as beams in buildings.

Size:

• Furniture beetle: Smaller in size, usually about 4-7 mm.
• Deathwatch beetle: Larger, typically 5-9 mm in length.

Sounds:

• Furniture beetle: Does not produce noticeable sounds.
• Deathwatch beetle: Known for its characteristic ticking or tapping sound, made by adults banging their heads against the wood to attract mates during reproduction.

Life cycle:

• Furniture beetle: The life cycle is generally shorter (from 1 to 4 years), depending on the wood's moisture content and other conditions.
• Deathwatch beetle: Larvae can live in the wood for up to 10 years before becoming adult insects.

Type of damage:

• Furniture beetle: Causes noticeable structural damage to furniture and decorative elements.
• Deathwatch beetle: Can lead to more serious damage to architectural structures due to its preference for hardwood, which is crucial for the stability of buildings.

Exit holes:

• Furniture beetle: The exit holes are slightly smaller, about 1-2 mm in diameter.
• Deathwatch beetle: The holes are larger, around 3 mm in diameter.

In conclusion, the main differences lie in size, the type of wood infested, life cycle, and behavioral characteristics, such as the sound produced by the deathwatch beetle.

• Wood flour or wood chips: Residue produced by wood pests when they eat wood.
• Weakening of the wood: Signs of structural damage and decay of the wood.
• Holes created by adult insects leave the wood.
• Insect presence: Visible presence of insects or their larvae in the wood.

Timely detection and removing of woodworms are crucial to prevent structural damage to wood structures. Through regular inspections, prevention and, if necessary, pest control, wood pests can be effectively controlled and combated in the long term.

Microwave equipment is the perfect choice for wooden houses, antique shops, and restoration studios. The killing is immediate, toxic-free, eco-friendly, and safe for the operator. Microwave energy affects larvae immediately, containing up to 97% instant boiling moisture, plus there is steady heating of the surrounding material to a temperature above 55-60 degrees. This is enough to get rid of both eggs and adult insects.

There should be a microwave Shashel in every log cabin. Without waiting for the whole structure to be infested, the entire population is zeroed out. The homeowner always knows the location and can treat the "infected" places first. It should be noted that the equipment perfectly controls the humidity of the wood and perfectly copes with mould, which often accompanies the pest.
