…ss than 1 mm (see arrow). They are always found close to the holes made by furniture beetles, on which the chalcids live (see p. 152). Common furniture beetles The exit-holes have a diameter ol 1.5-2 mm. This furniture beetle occurs in many kinds of deciduous and coniferous trees. The tunnels are most aften in the sapwood, but they may enter the heartwood. The wood dust is a uniform colour and feels gritty. The faeces are almost cigar-shaped. Thi…
Furniture mite
…months, these mites will also become extinct. In the event of an attack on furniture, padded furniture should be moved away from the walls so that good air circulation can be created. To help the process along the way, extra heat is applied to the room – the higher, the better – and at the same time a window is left in a tight space for a few days. These measures can remedy an immediate situation, but there is a risk that the mites will reappear u…

Dark flour beetle larva The dark flour beetle is now a common food pest in Denmark, Norway, Finland and Sweden, but is virtually unknown in most other countries. In Canada, Germany and the former Soviet Union, it is occasionally found in houses and storages, but regarded as a rare and relatively harmless species. British researchers suggest that the relatively high indoor temperatures…
Ham beetle
…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…
Wasp beetle
…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.

Fur beetle
…e 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 near flowering plants. This is because the adult fur beetles feed on nectar and pollen. However, the larvae cannot live on this diet. The female fur beetle typically lay their eggs in mice or bird’s nests. Here there is plenty of fur an…
Bread beetle
…e holes are confusingly like the holes in a tree that has hosted the borer beetle larvae. Bread beetles are not limited to one region, but are found all over the world. And often it is through shipping that the beetles are spread across the globe. Their history of shipping is not exactly good, as the bread beetles liked to be annoying and unwelcome guests on board the ships. This is not least due to their ability to plunder the crew’s meals. And i…
Merchant grain beetle
