Latin: Ernobius mollis The soft wood borer beetle is not a rarity in this country, and it likes to settle in dry bark-clad conifers. The soft wood boring beetle – also known by its Latin name Ernobius mollis – differs slightly from other types of borer beetles. This is due to its skin skeleton, which is not as hard as in other of its fellow species. Appearance The fully grown soft wood boring beetle can grow between 3 and 6 millimeters long. It i…

…encountered along the Danish coasts and around the port cities. The wharf borer beetle is also called by its Latin name Nacerda melanura. There is a reason for the beetle’s name with maritime associations. Because it is not only in Denmark that the beetle prefers to settle in coastal and port areas. The beetle is widespread in similar places throughout the temperate zone, where the wharf borer beetle is spread through shipping. The wharf borer be…

…that consists, among other things, of the larvae’s excrement. Damage If a borer beetle has attacked woodwork, it is a clear indicator that the wood is affected by moisture or rot. In such cases, the borer beetle attack is actually a secondary problem. However, this does not mean that their presence cannot present challenges. An attack from the borer snout beetles in interaction with moisture in the woodwork can have an accelerating effect on the…

Places to find the beetle are most other completely sealed tree like beams and raft…

…but in Denmark, at least in comparison with other pests. Destructive flour beetle beetles were first found in Denmark in 1943, but they have since appeared more often. The Destructive flour beetle most likely came to Denmark from the tropics in Africa in connection with trade of goods between the two places. Anyhow it has also occurred in other countries that have traded with this part of the world. In Danish, the Destructive flour beetle is named…

…e can grow up to 8 millimeters long. Biology and behavior The brown carpet beetle is a beetle in the subfamily (Attageninae), which all share the same common feature. They live on the dry remains of plants and animals and are not unwilling to consume all that is left by other animals. The brown carpet beetle originates from Africa, where the temperature is somewhat different than in Denmark. This affects the beetle. It thrives best at temperatures…

…al years before they pupate and undergo development into fully grown brown wood beetles. When the fully developed brown wood buck is ready to leave the tree, it does so through a fly hole, which it gnaws at the surface of the tree. These fly holes are, like the aisles, oval and measure approximately 5 x 13 millimeters. The passages that the larvae leave behind are filled with drilling dust, which consists of the larvae’s excrement. This flour is s…

As with the preventive treatment, the product must be suitable for protection against house bucks and borer beetles. Be aware that surface-treated wood such as lacquered and painted wood does not have the ability to absorb the agent sufficiently. This is because the protective agent ca…

…f beetle. Biology and behavior The Australian spider beetle belongs to the woodboring beetle family (Anobiidae) and to the subfamily thief beetles (Ptininae).

The damage from the violet tanbark beetle, has no effect on the lo…

…beetle belongs to the family of beetles (Anobiidea), and in the subfamily wood beetles (Xyletininae). The typical lifespan of an adult tobacco beetle is about one month, during which time the females can lay 30-40 eggs. Under favorable conditions, the female can lay up to 100 eggs, and the beetle can therefore spread quickly. The tobacco beetle can fly, and especially at temperatures above 18 degrees with dim light. At 25 degrees, the development…

…se liquid wood preservatives as these agents have little effect on this species. You can however use heat treatment for control. The wood must be heated up to 75 degrees for minimum eight hours or dried, so the humidity drops below 14%. Treated wood will never be attacked by wood wasp larvae. Wood wasps does have a negative impact on forestry, which is why there are import restrictions of conifers in Australia, to avid infested wood. The export of…

And if the woody beetle has been at stake in the tree, the corridors are clearly visible due to the dark dead fungal threads that have been left behind.
