Woodlice

…woodlouse ( Latin: Order Isopoda) Like slugs, these familiar crustaceans prefer damp conditions. They do not normally feed on paper but if, for example, a pile of damp, mouldy newspapers is left lying on a cellar floor, woodlice will more or less destroy them….

Woodlice

…ll become desiccated within a few hours. Woodlouse These small crustaceans feed mainly on plant matter, but may also gnaw dead animals. Those that are seen in houses and cellars usually belong to the species Oniscus asellus and Porcellio scaber. When large numbers of woodlice are seen indoors it means that the atmosphere is too damp. Sometimes several of them may find their way into a room or cellar, and these will usually be newly hatched individ…

Life cycle

…w melts and the hollows form puddles. They hatch in late March. The larvae feed on the finely ground organic matter and microorganisms that are found in the water. It takes the larvae a few months to become adults. Pupation also happens in the puddle, and finally, the mosquitoes can leave the puddle as adults. This usually happens in mid-May. There is only one generation of these mosquitoes every year. The life cycle of the beach meadow mosquitoes…

Booklice

…y movements, and they can also make small, rather clumsy, jumps. As the name implies, booklice are found between sheets of paper in libraries and archives, and also behind loose wallpaper and in herbaria. They do not eat the paper itself, although they may feed on the glue in glazed paper, but they subsist primarily on the moulds growing on the paper. In- deed, the presence of numerous booklice is a sign that the paper is being kept too damp. Some…

Ticks

…le is 3-4 mm long. The mentioned size only applies when they have not been feeding. As soon as the tick have feed their size expands incredibly, and a blood-filled female tick can become 1.5 centimeters long. The blood is stored on the hind body in a reddish-brown and leathery skin. Biology and behavior The population of ticks varies in Denmark. The reason for this is that they have certain damans to the environment. They are sensitive to desiccat…

They can also survive on dried fruit, beans, chocolate, and spices. As they are not a picky animal. The way to recognize the damage of flour beetles to one’s foods is when the infested foods get an unpleasant odor and taste. They also get a grayish color. It is not recommended to eat co…

Animals that attack textiles

…render it digestible. In the wild insects that can digest keratin probably feed mainly on the remains of animals left by carrion-eaters, but they are also found in nests and lairs containing down or hair. However, keratin alone does not provide a sufficient diet for the normal development of an insect. It lacks, for instance, certain vitamins. In the wild the insect will have plenty of opportunities for supplementing its diet, but this is not poss…

Eggs and larvae

…like nits, but sprinkles off the host animal, wherever it is. Flea larvae feed on various types of organic material, supplemented by the adult fleas’ bloody excrements. Flea larvae are blind and worm-like, and have bristles around each segment of the body. They are white, but the skin is transparent, so you can see the dark intestines. If flea larvae are disrupted, they roll up into a spiral shape and play dead for a moment. After four larval sta…

Thrips

Although, as already mentioned, they are plant suckers their mouthparts can penetrate human skin. Under certain circumstances thrips enter houses in large numbers. They have a special habit of creeping into narrow spaces and they are therefore found behind wallpaper and even behind the glass of pictures. However, they soon die in the dr…

The khapra beetle

…rnation. That way they can survive for years until food arrives to the warehouse. Its ability to hide makes the extermination quite difficult. Khapra beetle, adult and larva This inconspicuous beetle has become one of the world’s most unpopular storage pests. The khapra beetle was introduced in the United States at some point in 1952 – 1953. Here it spread quickly to a large part of the American malt houses, mills and grain storages and it was exp…

The bacon beetle

…here are two dark crochets. The bacon beetle was once a feared pest in any household. It lived in smoked hams, sausages, which was hanging from ceilings, and damaged dried fish. Today, with most meat stored in the refrigerator or freezer, the bacon beetle has no economic role in private homes. When bacon beetles are found in homes, they often come from leftovers that have been forgotten because of illness or travel, from dead mice under the floor,…

The confused flour beetle

…t can damage grain and feed storages, but can also be found in grocery warehouses and in private households. The confused flour beetles do not only eat cereals but can also infest dried fruit, spices and chocolate. Infested flour quickly becomes warm, gets a greyish colour and moulds easily. Heavily infested items get such an unpleasant odour and taste that they are unsuitable for human consumption. The beetles need temperatures between 18 and 21…

Animals that come inside for the winter

…e to find sheltered places where they can spend the winter and for this outhouses and lofts are very suitable. They must also have reached a stage in their life history in which they can go without food and can withstand the unfavourable climatic conditions. The stage concerned will vary from species to species. Some overwinter as eggs, some as larvae and quite a few as pupae, e.g. cabbage white butterflies. There are others which spend the winter…

Skin beetles

…th oval or round body shapes. The surface is almost always covered with small, coloured hair or dandruff, which provides distinctive drawings. The larvae are covered with long hair of various kinds. Some of the hair is the cause of skin irritation in people. They feed primarily on the dry remains of plants and animals. Some of the skin beetle larvae belong to the carrion fauna. They first appear in carrion when maggots and others have eaten most o…

Bats

…d the pipistrelle (Pipistrellus pipistrellus) are perhaps the species most commonly found in buildings. Despite a certain amount of human distrust and aversion, bats are completely harmless lodgers that neither gnaw nor in any other way damage the building. In northern Europe bats feed on insects, which they can catch in the air. When in flight, they emit continual ultra-sonic sounds, which are reflected back to their ears by insects and other obj…

Kestrel

They are good fliers and seek towards light. You can often find them in windows far from the place where they have gone through their development….

Grain weevil

…Prevention and pest control If you are left with a completely emptied warehouse or an empty silo where you know that there have been grain weevils, the inside must be cleaned very thoroughly. In private, you should store dry food and animal feed cool and with a tight lid, so you avoid both gather and other pests in your food. Also, keep an eye on the foods that you do not use as often as others. To prevent grain weevils, it is best to use a poiso…

Ant beetle

…Ham beetle ( Latin: Corynetes coeruleus) This beetle is similar to the copra beetles, but is a uniform iridescent green. The larvae feed on dried carrion and may also eat smoked meat products. In roof spaces suffering attack by wood-boring beetles it lives as a predator (p. 121), its larvae hunting the wood-boring larvae like a mole hunting earthworms….

Biting lice

…, they usually have two claws on each leg, and they do not suck blood.They feed by gnawing fur and feathers and also scraps of skins. They do not affect man. Biting lice attach their eggs firmly to feathers or fur and the whole development from egg to adult takes only a couple of weeks. They are so dependent upon the warm, damp climate under feathers or among fur that they only survive for a few hours after the host animal dies. Dogs and cats each…

They are sometimes found in food stores, shops, canteens and even in private houses. In most cases they do little or no damage but they can be rather annoying. In hospitals where conditions are more or less ideal for them these ants may be dangerous as possible distributors of dis…

A: The Waste Niche

…lace to find food. They rarely live directly in the products on which they feed. Offspring of cockroaches and crickets, earwigs and silverfish seek food the same way as the adult insects immediately after hatching. Offspring of ants, rats, mice and birds live in special nests and are fed by the adult animals while growing up. The birds, rodents and insects in the waste niche are doing very well on spilled food in the form of waste. However, they f…

Scorpions

Scorpions Scorpions (Scorpiones) feed on insects and spiders which they catch with their palps and – sometimes – kill with their venomous stinger, which otherwise is primarily a defensive weapon. There are no Danish species. (Pseudoscorpions are harmless Danish animals that do not have anything to do with the real scorpions). Scorpions belong in the tropics and subtropics. Fig. 97. The scorpion. (Sci.Am.) Several smaller species can be seen in so…

Goat moth

The larvae live and feed in the wood for 2-3 years and when fully grown they sometimes leave the tree they have been living in and seek a suitable place for pupation. Hole in wood from goath moth larva. This usually happens in the autumn when the larvae may be up to 10 cm long, and they may choose any soft timber to provide them with protection. They metamorphose into moths in the following su…

The lesser mealworm beetle

…opics and can be found as it eats mould from very damps cereals, flour and feed residues. It had its first chance to form large populations when we began feeding chickens in large chicken coops with litter in which manure accumulates for a long time. It performs the important piece of work it is to reduce fertilizer volume and it also reduces the amount of fly larvae. In laboratory tests it has been possible to show that the lesser mealworm beetle…

Follicle mites

The premises

…h pupae and sleeping moths. On humid walls, where microscopic fungi exist, mites, booklice and plaster beetles live. If the walls are very damp it is possible that you will find slugs, woodlice and springtails on them. You will rarely find pests in the middle of the floor during working hours, but if there is a layer of dust on the floor or other horizontal surfaces, one should not neglect to look for tracks in the dust. If there is no dust, one c…
