Animals in timber

…tive enzymes in their gut (this applies, for example, to the larvae of the house longhorn beetle), but the majority have a different method, for they have established an association with micro-organisms which help to break down the wood. Finally, there are some species, such as the powder post beetles, which are dependent upon the presence in the wood of starch or sugar. ‘Wormholes’, fly holes of the common furniture beetle, stand for many as a gu…

Animals that bite, sting and irritate

…or example in the hornet. For an animal that sucks blood it is normally in its own interest that it should do so with as little disturbance as possible. The sucking proboscis is normally a delicate structure consisting of two tubes, one very thin down which saliva passes and the other a little larger through which the blood mixed with saliva is sucked up. The saliva may contain substances which prevent the blood coagulating and it may also contain…

Long-tailed Silverfish

…e made between, for example, apartments. Control of long-tailed silverfish with poison If you choose to treat with poison, it is equally important that you check your home for bearded prey before treatment. Edible poison is laid out in small gel drops under the floor panels at 1-2 meter intervals. In addition, small drops of poison should be placed in cracks and crevices and in dark places where long-tailed silverfish can reside. Good advice again…

Goat moth

The white-marked spider beetle

…is common in nature. Males are elongated, with almost parallel sides, while the female has round arched elytrons. On the prothorax, it has two stripes of closely spaced white-yellow hair, which comes together in the back and draws a V. On the elytrons there are 4 white-yellow spots….

Brown Carpet Beetle

…On summer days they fly in the open and like this they find their way from house to house, but they usually spread by being brought about in goods, luggage or furniture. In residential buildings, they can spread through piping and other crevices. Given how common the brown carpet beetles are in European homes, it is remarkable how few actual damages have been reported over the years. Usually the larvae live hidden in cracks and crevices where they…

Woodwasps

…develop into larvae that can grow up to 4 centimeters long. The larvae are white yellow with three sets of breast feet, and at the tip of the hind body they have a short and dark thorn. Biology and behavior The appearance of this pest can be frightening to many and result in panic. Here, it is important knowing the difference between this wasp species and the common wasp, as the wood wasp does not attack humans and at the same time can neither sti…

Violet tanbark beetle

…ood but it will have a practical meaning to the wooden boards that is clad with bark. Here the pest can gnaw its way out through the plates. The damage will be severe on wood boards, if lead or cardboard roofs has been laid directly on top of the bark-clad wood. The holes from the pest can result in water damage as well as an increased risk of fungus or rot. Prevention and pest control If you want to avoid an attack from violet tanbark beetle in c…

Leaf beetle

…t a pest controller or a consultant in horticulture or agriculture to deal with the problem. Sometimes the leaf beetle also finds its way into our homes. This is done based on a search for food or a suitable place for the beetle to overwinter. And as a rule, there is only a single or a small handful who have randomly searched the home. If the leaf beetle is inside the home, there is no need for an alarm. It cannot harm people, housing, or furnitur…

Flour beetle

…hind are slightly darker. A flour beetle larva can also be taken as a worm with its chubby shape. Biology and behavior The 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 ca…

Arthropod senses and behaviour

…rthropods are probably made aware of the temperature in the first place by its effect on their internal body processes. The arthropods are therefore very well provided with senses, which are often extremely sensitive. Bluebottles, for example, can smell meat at a distance of several kilometres and find their way to it with unfailing accuracy. The behaviour of invertebrates often appears to be extremely rational but there is no evidence that they c…

You should powder the places where this pest is able to enter the house, and in this way make sure that the can not the house through cracks and crevices. If you want to treat against millipedes that have already entered the house, you can also do so with insect powder. To treat in the most efficient way, you should powder door openings, door frames, window frames, panel cracks, and similar places, wher…

Callidium violaceum

…tem under the bark of a spruce raft. The larvae are often brought into the house with bark-covered timber, and are common in firewood (only softwoods), and in planks of pine or spruce that still have the bark on. The larvae can thrive in timber until the whole of the layer between bark and wood has been used up, but the attack cannot spread to timber without bark. The best method of stamping out an attack is simply to remove the bark. As in the ca…

Skin beetle

…e to remove and destroy the source, thoroughly clean the area around the site and treat it with an insect repellent or spray against creeping and crawling insects. Larvae can also be found under the floors, and here they can be more difficult to get rid of. It can be a challenge to treat the area with pesticides. You should possibly repeat the treatment – and arm yourself with patience. If you want to prevent the Dermestes haemorrhoidalis, you sho…

Yellow swarming fly

…yellow swarming fly also has a particular tendency to visit – or invade – houses covered with ivy or wild wine. The reason for this is presumably because such areas can constitute ideal natural wintering sites for the grass fly. However, there is no reason to move heaven and earth if the yellow swarming fly should have found its way inside. They cannot cause damage inside but can at most be an annoying element. At the same time, the flies will au…

The house sparrow

…rregular, globular nests are lined with plant fibres, hair, feathers and random material such as paper and plastic. The sparrows get 2-3 broods during the summer. They feed the young with insects, but the adults live predominantly of waste from households as well as grain and seeds. House sparrows forage on the ground, often in flocks. There are several species of sparrows that – superficially – looks like house sparrows, but they do not build nes…

The house dust mite

…s have grooved skin. It is possible to find them in animal feed, etc., but house dust mites cannot compete with flour mites, sugar mites and mould mites in food and feed under cold, Northern European conditions. In warmer climates dust mites can be found in mouldy flour, along with other fungi-eating mites. Beware that the inhalation of dust mites dust may well be hazardous to the health. This applies especially if you are one of the many people,…

Common house mite

…large numbers. They occur particularly in upholstery stuffed with fibre derived from palm leaves. Nowadays these mites do not present any serious problem, but they may be a nuisance in very new houses which are still damp and in holiday houses which remain unheated for most of the year. Like all the other mites they quickly die if they become desiccated….

Common house spider

…midity, such as bathrooms and outhouses. It also occurs under the eaves of houses and in stone walls. The common house spider is an impressive animal. It can get so big that some people think it may be a tropical bird spider. Unlike that of many other species, the web of this species is not a regular work of art, but consists of an apparently tangled mass of threads, often covered in dust. It is usually constructed in a corner and is then triangul…

Jet ant

…s. In rarer cases, they can build the nest directly in the woodwork on the house, which create problems for the house owner. The jet ant feeds mainly on smaller insects, plant juices and the excrement from aphid. They create paths from their nest to the tress filled with aphids, those trails are maintained each year and they can be up to 40 meters long. The ants create an extremely humid environment around their nest, and they will gnaw in the tre…

…he lower lip of larvae. It is sticky and whatever the larvae live in along with its droppings gets stuck in these threads. As the adult moths, larvae also shun the light, but when they grow up they climb to the surface of whatever they have lived in. At this point they can easily chew their way through paper and plastic, which block the way. They pupate either on the surface of a product or go hiking, often towards walls, to find a crack or crevic…

Tapestry moth

…upae are left behind when the tapestry moth have left the fabric. Tapestry moth This is the largest of the moths that attack textiles, and it has a tendency to• feed more on coarser materials than the other textile moths, including such things as horse hair, coarse furs and skins. Like the preceding species it thrives in humid conditions, and nowadays it is found especially in outhouses and stables. It does not attack wallpaper, but is a serious p…

Wine moth

Larva of wine moth gnawings in cork Wine moth ( Latin: Oinophila v-flavum) This is not really a food pest, but it is somewhat of a specialist, that i often found in wine cellars where the larvae gnaw holes in the corks. They thrive particularly in damp cellars, feeding on the mould growing on the walls and on the wine corks, and what is worse they can live in mouldy corks. The debris produced by their activities can be seen hanging from the corks…

Common woodboring beetles

…imal conditions for the eggs. The eggs of the common woodboring beetle are white and from them emits an adhesive that allows the eggs to stick to the surface where they are laid. After about 3 to 4 weeks, the eggs hatch and small white woodboring beetle larvae emerges. The larvae gnaw further into the tree, as they undergo their full development. The woodboring beetle larvae live exclusively inside their holes in the tree, where their full develop…

German cockroach

…the yellow-brown body with two dark stripes on the back shield. The cover wings cover the flying wings, but it seldomly happens that the German Cockroach uses their wings. Biology and behavior A German cockroach typically belongs in a warmer climate than in Denmark, and therefore they are also dependent on being able to find warm places to live. Cockroaches eat everything and they are especially active during the night. In the light hours, they h…

Merchant grain beetle

…small, they can get around easily from apartment to apartment or from warehouse to warehouse. Like so many other beetles and insects, the development of the merchant grain beetle can depend very heavily on the environment in which it finds itself. A merchant grain beetle can grow large in a shorter time if there is warmer and higher humidity. The ideal climate for a merchant grain beetle is 37.5 degrees and 70% humidity, and in this climate, it c…

Dark giant horsefly

…and other insects, but there are lotions that can soothe the pain. Lotion with lidocaine helps with both pain and swelling after a bite, and this can typically be bought at the pharmacy. Local anesthetic gels can also help. After one bite from a horsefly, you typically do not want to try that again, but you can take some precautions. The easiest way to avoid bites from horseflies is simply to stay away from their preferred environment, i.e., swam…

Rice weevil
