…ween the three different species in Denmark in their color. The first is a red-legged ham beetle, also called Necrobia rufipes.

This one also has a body that is dark and metallic blue, but it is red on the chest (which can also be seen on the “back” of the beetle). This reddish color…

…place the wood with treated wood, such as pressure-impregnated timber. However, it is also possible to treat the wood with a wood preservative that protects the wood from both insect and fungal attacks. In hard-to-reach areas, it can be an advantage to treat with an insect powder that is distributed on the areas where the beetle moves. It will kill the beetles before they have time to lay their eggs….

…ir own whitish cocoon in which they pupate. The cocoon has an almost tissue-paper-like appearance, and the webs of the larva can be seen as thin threads and spun cocoons in the infested area. The development from larva to fully adult thief beetle lasts about 3 to 4 months if the larva has good conditions e.g., at room temperature. When the larvae are fully developed, they most often leave this safe area. This means that they sometimes have to clim…

…larva has been feeding on bark or sapwood. Very common in houses where bark-covered timber is used (see p. 122). Dendrobium pertinax exit-holes in timber Dendrobium pertinax The exit-holes have a diameter of 2-3 mm. This species is found almost exclusively in softwood that has been damaged by damp. It works mainly in the spring wood, while the summer wood remains behind in the form of lamellae. The wood dust is similar to that leftby the Common f…

…ow as Anobiidae. The size of the tobacco beetle is around 2-3 mm and a full-grown beetle can measure up to 4 mm. Therefore, we are talking about a very small beetle, that is difficult to spot.

…ns. Under the bark, the larval passages will stand out clearly as approx. 1-millimeter-deep grooves, forming a large pattern in the wood. However, the grooves may be deeper than that. Just before the larva pupates, it gnaws even further into the tree. The larva digs approx. 1 centimeter down into the wood to achieve a more protected position in the tree. Within one to two years, the soft wood boring beetle is fully developed, and it is getting rea…

…ecognize, size wise they are up to 1 cm long. One can take the ordinary fur- or carpet beetle larvae as a brown carpet beetle larva, as they are related. The easiest way to distinguish in between them, is by the location where they are found. If the larva is found indoors, it is most likely the brown carpet beetle larva. A common carpet beetle larva is typically found outdoors. Biology and behavior During the summer, one can find the fur beetle ne…

…For the female needs to suck blood from a bird between each laying. For non-laying red mites, the need for blood meals is not nearly as great and they can easily survive for 4 to 5 months without blood. The process from egg to adult red mite is over quite quickly.
