Drone fly larva

…ater 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 surface of oxygen-deficient water and breathe air. When fully grown and ready to pupate, the larva, often known as a rat tail larva, creeps out on to the land and seeks a suit- able dry place in which…

Honey bee

…ings to the finder. A bee has to visit up to 1000 flowers in order to fill its crop with nectar, and on a sunny day it may make up to 10 foraging trips. The production of a pound of honey would require 20,000-30,000 trips. When observing bees it is best to keep a few metres away and naturally not to stand in their line of flight. Even though modern bees by selection over many generations have become remarkably peaceful, they may occasionally becom…

Parasitic wasps

…sed for biological pest control on farms, in plantations, gardens and greenhouses. Some species can sting with the laying brood, but this rarely happens. If this happens, it is usually because you accidentally squeeze them. Prevention and control If many parasitic wasps occur in the home, it is usually because there is something that has already been attacked by insects. This is where the parasitic wasps will appear as the origin of them. This is…

Mold beetles

…home. If the mold beetles appear in the kitchen or other areas in the house, you should vacuum rather than wash the areas. When washing, you will simply add moisture again, which benefits the growth of mold beetles. It may be necessary to wash off with fungicides and mold killers in areas where there is clear growth of mold….

House sparrow

…n March and April the breeding birds collect nest material, mainly dry grass, hair, feathers and scraps of paper, which they use to build their untidy more or less spherical nests. A pair may rear two or three broods in the course of the summer. House sparrows forage on the ground, often in flocks. The young are fed on insects, but the adults live mainly on seeds and in towns on household waste. In the country they frequently invade stores of grai…

The premises

…e are and where they go. Regular inspections should of course include searching for mouse and rat holes and droppings. A lamp with ultraviolet light can sometimes detect rodent urine and hair. Fresh urine fluoresce with a blue-white colour, old urine turns yellow. Hair from mice and rats fluoresce with a blue-white colour. Traps containing feed for mice and rats can reveal whether there are rodents on the premises….

Booklice

…ve wings and live near lichen and moss. The indoor species have very small wings or no wings at all. Only a few of the dark coloured species have real, functional wings. When this kind of winged booklice occurs in foods, it is not uncommon to see the loose, torn wings be distributed among the booklice in the product. The indoor booklice prefer damp, dark places and they are most common in basements, attics and damp walls. This is among other facto…

Bats

…some cases, bats seek in and spend the night on ceilings and overhangs on houses. You can read more about bats in houses at the Danish Nature Agency. A female usually has one offspring, but in some species, it is not unheard of for her to have two offspring at once. The newborn cubs are completely naked and completely helpless. After 4 to 5 weeks, the young bat begins to train their wings and take their first flights. The cubs are a little insecu…

Fur beetle

…is right in the middle. At the back of the neck shield it has three small white spots. A fur beetle has fine but strong wings, so you can expect them to fly. The body is considerably larger than the head, and the hind body is absolutely the largest. The larva of a fur beetle is unique in their appearance compared to other larvae. A typical larva is an elongated little creature that is white, yellowish, or beige. But a fur beetle larva has a brown…

Rape blossom beetle

…e The rape blossom beetle is a small gloss beetle of just two millimeters. Its color is dark with a metallic shine that is usually greenish. Biology and behavior When the temperatures are warm, you can experience the rape blossom beetle flying around in even very large numbers. Like many other insects, the beetle is attracted to yellow colors. If you are wearing yellow clothes, it is therefore an open invitation to the rape blossom beetle, who wil…

Bed bugs

…round the intestines. The body is divided into three sections: 1) the head with mouth parts, antennae and eyes 2) thorax with three pairs of legs and usually two pairs of wings 3) and an articulated abdomen. The bed bugs are true bugs (Heteroptera) .The mouth parts of the bugs form an effective, sharp proboscis, which most use to suck sap. The vast majority of bugs have two pairs of wings, so also in this way the bed bugs stand out, being wingless…

Mealworm Beetle

…orm beetles and mealworms, this is mostly because they primarily are dealt with in the industry. By keeping the temperature low and the air environment healthy, you can typically prevent mealworm beetles and mealworms. If you have problems with mealworm beetles returning to your kitchen cabinets, there is most likely a place nearby where the mealworm beetles can reproduce, lay eggs, and thrive. You should look for a hatchery and if you can’t find…

The Brown wood buck

…y 5 x 13 millimeters. The passages that the larvae leave behind are filled with drilling dust, which consists of the larvae’s excrement. This flour is so compact that it can be difficult to scrape out of the wood. Damage Like so many other types of beetles, the brown wood buck prefers to lay its eggs in wood that is moist. This means that it is often damaged wood that is used for the purpose of the beetle. Wood that is still not very used for cons…

Tobacco beetle

…hield as well as long light brown hairs that are most evident on its legs. Its head is hidden under the neck shield. Biology and behavior The tobacco beetle thrives in a tropical or subtropical environment, and it is not a species what is particularly widespread in Denmark. It will often be found in climates with high humidity and high temperatures, but it can still live indoors in Denmark. In Denmark it will get enough heat because of the high te…

House centipede

House centipede (Latin: Scutigera coleoptrata) This centipede comes from the Mediterranean countries where it is often found indoors. It has been recorded a few times in northern Europe. Like other centipedes this is a predator which kills its prey by using the foremost limbs which are modified to form a pair of poison claws. In contrast to the small centipedes found in the garden, this species can, when disturbed, bite in areas where the skin is…

House sparrow

…y a harmless, quite attractive small bird when it builds in the eaves of a house (p. 183), but in food factories and stores it can do a lot of damage, and has been called a winged rat! Sparrows eat foods, foul them with their droppings and peck holes in packaging materials. They find their way in through any small hole and soon start to build their nests in the building. The first step in combating sparrows is to destroy their nests and prevent th…

Pests in House and Home

…he identifications are based entirely on characteristics which can be seen with the naked eye or with an ordinary good lens. The book has been written not only for the private house owner, but should be equally useful to all those who in their daily life have to deal with problems involving harmful animals in houses, shops, stores and factories. Far from all animals encountered indoors are harmful, so the book should also appeal to all those who h…

House centipede

…House centipede This animal has extremely long legs which are used as a kind of capture net when hunting insects and other invertebrates. It occurs naturally in central and southern Europe where it is frequently seen indoors, but is only found very occasionally in northern Europe, having been brought m from further south (see also p. 34)….

(1) The house dust mite and the sugar mite

…fungi found on dead plant material during natural degradation. The common house dust mite lives, among other places, in bird nests. It can form blooms in a damp, mouldy room, and it is usually the one you see in newly built houses that are heated, but have not yet dried properly. The sugar mite is on the other hand tolerant to cold environments and is therefore free-living. It is also the sugar mite that dominates in unheated storages containing…

Control of timber pests

…read rapidly and to penetrate the timber. When the attack takes place in a house all openings (doors, windows, etc.) must be tightly closed before the treatment is started. Smaller objects, such as furniture, can be taken away and treated in a gas chamber. No insect can survive a temperature of 55° C for over half an hour and this fact can be used in the treatment of timber pests. Provided they can withstand the heat small objects can be put in an…

Bumble bees

…ot been able to fetch sufficient food for them, but they now start to help with the building work and with collecting food, while the queen occupies herself more and more with egg laying. Bumblebee’s nest in abandoned bird’s nest Later on in the summer a bumble bee nest is well established with larval cells and stores alongside each other. It does not have the regular cells and the neat arrangement characteristic of a honey bee colony, nor is it s…

Dried currant moth

Fleas

…a cocoon spun from a salivary secretion. The cocoons are normally covered with dust and are therefore difficult to discern. The pupal stage may vary from one week to several months. The adult fleas may remain in the cocoons for a long time – even for years – waiting until an animal comes near them. Emergence from the cocoons is stimulated by vibration. If an infested house has stood empty for a long time the hungry fleas will start to emerge as s…

Black rat

…nd are therefore still present in certain large ports. They are associated with man to an even greater extent than the brown rat, but being more warmth-loving they do not occur out in the open in central and northern Europe. When black and brown rats are living in the same building, the former keep to the upper storeys, while the brown rats live on the ground floor and in the cellars. The black rat can live in much drier places than the brown rat,…

Brown rat

…of man and his domestic animals. Under favourable conditions, in grain warehouses and outhouses, brown rats will breed throughout the year and they are extraordinarily prolific. A pair of rats and their offspring can produce about a thousand individual in the course of a year. Brown rats live in groups, the individuals within each group recognising each other by smell. They are shy animals which are mainly active during the hours of darkness. They…

C: The dead plant niche

…hether they grow on food, packaging or on the walls of the premises. Brown house moth larvae can only develop in goods which are in moisture equilibrium with 80% RH or more. Therefore it is assumed that micro-fungi are also a necessary part of their diet. 3. Pests in decaying and fermenting plant tissue: The prune mite feeds on bacterial decomposition of sugar in fruit and can be found in dried fruit when the water content is too high. The house f…

Where?

…ite is mostly seen in Thisted and environs. The Eastern Pine Processionary with its etching hair is known from Dueodde on the island of Bornholm. The medicinal leech lives on Bornholm and in North Zealand. Black flies can form very large populations at the lower reaches of Gudenåens and Susåen. After traveling in southern Europe, bedbugs, house centipedes, scorpions, etc. can be brought home in luggage or camping equipment. Dogs that come to Denma…

Caredrina clavipalpis

…e autumn to find a suitable place to spend the winter. Occasionally they gnaw their way into various materials where they re- treat for the winter, and then pupate in the following spring and emerge as moths. The adult moths will not lay eggs again in the thatch, so the owner of the house experiences only a single generation and there is usually no need to take drastic action….

Pests in food stuff

…emove any shelf paper before cleaning. You may be tempted to wash the area with water, soap, or ammonia, but this does not affect the pests. This may have the opposite effect, as added moist will benefit them. In most cases, thoroughly cleaning with a vacuum cleaner is enough. Since the pests can spread far and wide, you can still encounter the animals after the treatment for a period. For this reason, it is essential that you also take measures p…

The stable fly

…h has suddenly become aggressive, but its close relative the stable fly, Stomoxys calcitrans. Fig. 41. The house fly (left) and the stable fly (right). (Kemper) It is mostly common in the fall, but can also be a nuisance during spring and summer. A stable fly looks like an ordinary house fly, but is characterized by its hard, pointy proboscis which clearly sticks out of the front of the head – like a stick. When sitting on a wall, you can recogniz…
