The spider beetle family goes by the common name Ptinus in Latin and in addition to the Australian spider beetle also counts family members such as the common thief beetle (Ptinus fur) and the brass thief (Niptus hololeucus), both of which are common pest in Denmark….

…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…

…llimeters inside the cracks in portions of 20 to 30 eggs. A house longhorn beetle female lays eggs for a few weeks, and during this period she can manage to lay several hundred eggs. The adult house longhorn beetle only lives for 10-15 days. After the larvae have hatched from the eggs, they gnaw into the tree through a small hole. Their journey goes towards the outermost layer, which is the most nutritious. The larvae eat the layer without at the…

…g its breast shield against the sides of the passage in the tree. Once the male and female have mated, the female lays her eggs. She lays about 50 eggs, which are placed in cracks, crevices, or old fly holes in the tree. When the eggs hatch, the larvae go down into the wood – which they live on – and where they continue their further development. The deathwatch beetle does not come into being from one day to the next. In building timber, the devel…

…t the Tobacco beetle has serrated feelers. Appearance Basically, a tobacco beetle is a small beetle species belonging to the woodboring beetles also know 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. The tobacco beetle has a light brown color at the front and shield as well as long light brown hairs that a…

…survive at temperatures below 9 degrees. If you are afraid of finding ham beetles or ham beetle larvae in your stock, a cool storage can do wonders. However, the beetles will begin to reproduce, pupate, and generally live again when the temperature rises, so this solution will not work if you have already found ham beetles in your stock. To prevent ham beetles, you can freeze your food to below -18 degrees. At this temperature, all stages of ham…

…or Although the wasp beetle tries its hardest to look like a wasp, it is a beetle. The wasp beetle is thus neither aggressive nor dangerous, but it tends to restless behavior, which can seem annoying to the people who do not like beetles and similar small animals. Before they are fully grown, wasp beetles also undergo a larval stage. While they are larvae, they prefer to stay in dead, dry deciduous tree in which they have hatched. It is only as ad…

…still intact and not dried out, it is an obvious destination for the borer beetle. The female lays her eggs in cracks and crevices in the coniferous bark. When the eggs hatch, the newly hatched larvae gnaw deeper into the bast layer of the tree, which forms the area between bark and wood. In this area, the larvae can feed on the inner part of the bark, just as they can devour the outer layers of the sapwood. If a conifer has been visited by larvae…

…ot exceptionally long and lasts only up to 2 months. During this time, a female bread beetle can lay about 100 eggs. It takes between 1 to 2 weeks before the small larvae hatch from the eggs. The newly hatched larvae are extremely small and measure only about ½ millimeters. They therefore easily penetrate seals and packaging that are not properly sealed. The larvae thrive best in very starchy and dry products such as pasta, biscuits, and crispbrea…

…nt merchant grain beetles in private homes. To prevent both merchant grain beetle and other beetles from trying to eat one’s food, one should make sure that all the foods that the beetles will go for, are properly packaged in air-tight concealers. In addition, you can minimize the risk by keeping the merchant grain beetles favorite foods (nuts, almonds, dried fruit, seeds, and the like) cool. If you live in an apartment and experience that the mer…

…r, they may become an annoyance if they stray inside your home. As the fur beetle female can lay eggs in different woolen fabric, where the larvae will eat the fabric when hatched. Appearance An adult fur beetle is only 3.5 – 6 mm long in average. It has a dark, almost black color all over the body and a slightly shiny surface. On the coverts, there are two white spots, which is right in the middle. At the back of the neck shield it has three smal…

The pupal tunnels of larder beetles are circular in cross section, with a diameter of c. 4 mm (seep. 120). Australian spider beetle exit-holes in timber Australian spider beetle The pupal tunnels are circular in cross section, c. 2 mm in diameter. They are normally not very deep and are often only pits in the surface of the timber ( see…

…l thoroughly, you will most likely encounter several the saw-toothed grain beetle in a period. This is because the beetles tend to wander around. They will, however, die out if you simply store this beetles’ favorite items in tightly closed containers in a cool environment. If you still after those measures encounter the sawtoothed grain beetle in larger numbers, investigate if the beetles are in neighboring apartments, as they can move around thr…

…e confused flour beetle belongs to the family Tenebrionidae. The average female beetle lays between 300 and 500 eggs, but they can lay up to 900. This can lead to up to five generations per. year, depending on how fortunate the temperature is. The optimal temperature for flour beetle reproduction is about 30 degrees, but they can multiply at lower temperatures, as low as 18 degrees. Below 18 degrees there is no reproduction, and the flour beetles…

…the seed plant on the flower so that it cannot bear fruit. A rape blossom beetle female can lay up to 100 eggs. The larvae hatch after one week, after which the subsequent larval development lasts about three weeks. When the larvae are fully grown, they let themselves fall to the ground. Here they dig themselves down and continue their transformation into beetle. This process lasts for about another three weeks. Damage As described, the larva can…

…aped and is white with yellow hairs. Biology and behavior To attract the females, the male makes a ticking sound, by banging his head against the woodwork. After mating, the female lays about 10 eggs, which are placed in cracks in the tree. The preferred cracks consist mainly of old fly holes or passages, where the newly hatched larvae will immediately drill into the wood. Throughout the rest of their larvae stage, they will stay inside the wood s…

…the male is seeming slimmer. This is the easiest way to distinguish the females from the males since the differences between the sexes are clear. Biology and behavior The red-brown longhorn beetle is found in July to August. The females lay all their eggs in stems and branches that are rotten and moist. Thereafter, the larvae live in the wood. Typically, it takes about two years before they are fully grown and start to gnaw their way out from the…

…rs. The small larvae usually take a year to develop into adult borer snout beetles, and the borer snout beetle can hatch all year round. When the adult beetles are ready to leave the tree, it does so through small fly holes that have a diameter of 1 to 2 millimeters. These fly holes are oval and have a slightly irregular outline. They leave passages with borer flour, which is a fine and dusting material that consists, among other things, of the la…

…ey begin to mate. This often happens in the female’s fly hole, where the female beetle can lay between 20 and 60 eggs. The female lays her eggs in protected areas consisting of wood. Cracks and holes in woodwork or dead trees are obvious places for laying eggs. As mentioned, she can also lay her eggs inside the fly hole. They prefer to find places with high humidity as this provides the optimal conditions for the eggs. The eggs of the common woodb…
