…black stripes on the back and black and orange parts at the hind body. The fly larva is white and have approximately the same length as the adult fly. When the larvae hatch from the egg, they enveloped in a pupa for a few days, where they develop into an adult housefly. After the pupa stage they move along walls and crack to a dark hole. In the dark hole, they develop and unfold their wings. After 24 hours, the flies can fly, eat, and mate. Biolog…

Methods of treatment in pest control
…nt method of keeping pests under control, and this applies both to private houses and to industrial concerns. Many invertebrates are immediately killed and removed by vacuum cleaning. As already mentioned, some pests thrive best in places where there is a deposit of dust. Fly swats Fly swats can be a useful weapon when only a few gnats or flies have to be dealt with. Heat Insects are sensitive to high temperatures and will be killed in half an hou…

Prevention and pest control The house marten is easily dispelled by noise and sound. House marten are particularly sensitive to loud noises and…
House longhorn beetle

Wood wasp exit holes in timber Woodwasps The exit holes have a diameter of up to 1 cm. They are circular, with completely smooth edges, and look as though they had been bored with a 10 mm drill. Wood wasps occur only in conifers, the larval tunnels being made in both sapwood and heartwood. The coarse wood dust is so tightly pac…

They can easily stay outdoors during the warm summer months in Denmark, but in the winter, they must move to special outdoor locations that are heated. For instance, in a waste pile, where the fermentation in the waste causes a high temperature. However, the house cricket can cope with cold to a certain lim…
Wasps
…are occupied with reproduction while the workers build the nest, feed the larvae and defend the colony. Worker wasps are actually females with undeveloped reproductive organs. Unlike the honey bee, wasps have not developed methods of storing food for the winter, and in temperate regions their colonies only last for one season. Each colony starts to break up in the autumn, and the workers die of cold. However, before this happens new queens and ma…

When the larva pupates and transforms from a larva to an adult moth, it happens in a brownish cocoon that has the shape of a torpedo. Under normal circumstances, only one generation of brown house moth will hatch per year. Damage As described, bird nests are popular targets for the brown house moth to settle. Here they can feed on the birds’ feed residues and nesting material. But s…

Here the larvae feed on the small root lice that are under the grass. Each season can offer many generations of new yellow swarming flies, but the fly only overwinters as an adult fly and not as a larva.

Other wasps prefer holes in the ground, maybe an abandoned mouse’s nest, or a hollow tree, as the wood wasps prefer. She then start building the first nest, spherical, about the size of a ping pong ball. It contains 10-20 hexagonal cells and she lays an egg in each. When the eggs hatch, she must fetch food for the larvae,…

Biology and behavior As described, banana flies are incredibly fond of fermented fruits and vegetables. They can travel far if they catch a deliciously fermented scent. This is also the reason why the banana flies are frequent guests in our kitchens, which can be a true p…
Mealworm Beetle
…eetle belongs to the family of shadow beetles (Tenebrionidae). Both adults and larvae are nocturnal. The adult beetles can fly and can be experienced in the middle of summer. The adult female beetle lays about 200 eggs during its 2–4-month adult life. The eggs are laid in starchy products, such as flour, grain, bread, and cereals. It takes a long time for the mealworm to develop; the development from egg to larva and to adult beetles can vary betw…

Flour moths is rarely a problem in private homes, but it can nonetheless be a problem in certain situations. Most often, the moths and moth larvae found in private homes are instead a two-colored seed moth. Flour moth is more often a problem in the industry. Appearance The flour moth has an elongated shape with narro…

Spider faeces are greyish-white and liquid when deposited, and they occasionally contain the remains of the prey’s integument.

You can also tell the difference between the cluster fly and the housefly by the fact that the wings of the cluster fly almost completely cover each other when standing still, almost like when a human is sitting with its legs crossed.

Drone fly larva
(Latin: Eristalis tenax) Drone fly and larva This is the larva of a hoverfly (Family Syrphidae), and it is not very well known, perhaps because it lives in drainage channels, in pools receiving water from dunghills and similar places with water that is grossly polluted with organic matter. At its rear end this larva has a breathing tube which can be extended like a telescope to a length of up to 15 cm. With this organ it is able to reach the surf…
Bats
…are formed by a thin fold of skin that is located between the bat’s arm, hand, and fingers as well as the side and hind legs of its body and can be stretched out. There is also fly skin between the tail and the hind legs that continues all the way down to the feet. However, the feet are completely free of the skin. The feet have a completely different purpose, as the bat uses them when it hangs upside down and rests, or when it has to crawl aroun…

It is also possible to get rid of the bread beetles by freezing, but it requires temperatures below -18°C for several days to get rid of all stages of the bread beetle, which is a lot more complicated. In addition, you can control the bread beetle with insect spray. Please note, however, tha…
Brown dog tick

Prevention and pest control The house fleet originates from warmer latitudes and is therefore sensitive to the cold temperatures on Danish soil. This means that in Denmark it cannot overwinter outdoors or in unheated houses. Therefore, the control of the tick should preferably be directed towards treating the dog, just as one should find any breeding and hiding places indoors. Often,…

Some of them are merely transferred from the forest as eggs or larvae, and cannot live in timber that has been worked.
