Control

…e itch mite control product is on the body, you cannot be infected by itch mites. When the 24 hours are up, any mites on clothes and in the surrounding environment will be dead or unable to infect. Therefore, the washing of clothing and bed linen is not a necessary part of the itch mite control. If you feel most comfortable by washing your clothes and bed linen, you should of course do it anyway. In this case, it is helpful to know that washing th…

Transmission of infectious diseases

…single-celled micro-organisms and eggs of parasitic worms that is found in house flies and cockroaches have isolated several of the types that can cause serious diseases such as dysentery, typhoid, polio and tuberculosis. Micro-organisms exist on the outside of the insects, on hair and mouth etc., but here they normally only survive a few hours. House flies, cockroaches and ants may also obtain micro-organisms when they eat. In the intestines of t…

Some insects are unhealthy to eat

…t it is pests alone that cause sickness and even death to animals. Fungus and changed nutrition values are also factors. Pests are visible in the feed and therefore they are often blamed when feed quality is low….

Precautions against infestations by pests of textiles

…ich use the fragments as nest material. As mentioned on p. 94 insects that feed on wool are dependent upon a dietary supplement in the form of ‘dirt’ on the material. It is, therefore, important that clothes should be clean before they are stored away for any length of time. Materials that are newly washed, chemically cleaned or pressed with a warm iron will be free of pests and will need no further protection apart from being packed carefully in…

Sucking lice

…w which can grip hairs. Lice feed exclusively on blood and as they have to feed twice a day if they are to remain in good condition they can only survive for a few days in the absence of a host. A louse that is really hungry may be so greedy when it does again find a host that it feeds until it almost bursts. Lice are completely dependent upon the special microclimate found near the surface of the skin. If the temperature changes as, for example,…

Gamasid mites

…Gamaside These are very large, yellow-brown, active mites with long legs. Most of the species feed as predators on other mites and on small insects, but some, e.g. Kleemannia plumigera, feed on moulds. Now and again they occur in new houses that are still damp, or in lofts with damp hay or straw where they may multiply in large numbers, and find their way down into the house….

Mill or flour moth

…places after 2-3 weeks. Mill moth larvae prefer wheat flour, but will also feed on all sorts of grains, cereals, seeds, macaroni, dried fruits, cocoa, nuts and almonds. In mills the silken threads may cause a blockage of piping, funnels and sieves, so that the process has to be stopped for a thorough cleansing and possibly gassing. In the house it will normally be sufficient to discard the tainted goods, but it is as well to remember that larvae r…

Bryobia praetiosa

…les are never seen so the species must breed parthogenetically. These mites cause absolutely no damage in the house and they very quickly die in the dry climate. They are completely dependent upon the presence of plants on which they can feed. Normally they are only seen in houses where the lawn goes right up to the walls, so the most rational method of control is to create a break between lawn and wall. This can easily be done by having a strip o…

Carpet beetle

…nd outside during the summer and. land on flowers where they feed on nectar and pollen. They often find their way indoors. The eggs are normally laid in the nests of mice and birds, and the larvae, which have a characteristic tuft of hairs at the rear end, feed on hair, feathers and offal. In the house this beetle may lay eggs in woolen textiles or in other places where there may be food for the larvae, as for example in cracks in flooring or pane…

The yellow mealworm beetle

…ggs hatch in a month. Both beetles and larvae can travel long distances in houses and warehouses, especially when in the larval stages because they seek a sheltered place for pupation. These insects might jostle their way through pipe ducts and vents. Fig. 5.30. Yellow mealworm beetle. a: larva, b: pupa, c: adult, d: egg surrounded by flour particles, e: antennae. The yellow mealworms beetle is not a significant pest compared to years ago when it…

Carpet beetles

…und which is why they rarely gnaw large holes in textiles. The larvae also feed on dead insects, which is why insect collectors fear this pest. The development from egg to beetle will often take at least 12 months, depending on the conditions in which the eggs are placed. Indoors, the larvae are active throughout the winter where they eat and change skin about ten times. They pupate in May-June and a few weeks later they fly out like adult carpet…

The masked hunter

…sh animals. They are 1.5 cm long. Masked hunters are predatory insects and feed on other insects, which intestines they suck out. There are examples of people being bitten while sleeping or the bugs have bitten in self-defense. The bite is painful and the skin reaction is rather strong. In housing with bedbugs, there are sometimes a lot of masked hunters, which feed on the bed bugs. However, usually the masked hunters that are occasionally found i…

History of the dark flour beetle

…lives in birds’ nests and the dark flour beetle has an appetite for birds’ feed, and the temperatures in the indoor bird cages. Oddly enough the dark flour beetle is uncommon in international trade. The British import statistics, as already mentioned a few times, include long lists of species of beetles that have been seen in over 100,000 shiploads exported to British ports. The list drawn up by the beetle experts did not mention the dark flour be…

Mealworm Beetle

…t you can also observe them in sparrow nests, where they survive on wasted feed and they can easily hide in the nest. Damage Mealworms are harmful to humans, as they can infect one’s kitchen cabinets and food. Their presence in flour, grains, and bread can be extremely frightening for some people, perhaps because of the mealworm’s appearance. It should be noted that some people use mealworms to feed aquarium fish and various animals in terrariums,…

Pigeons

…every season. Both parents participate in incubation and later on also in feeding of the chicks. Pigeons feed their chicks in a very particular way. Their basic food are seeds of various kinds, and this is not optimal feed for chicks. However, a protein-rich liquid “pigeon milk” can be made of the seeds, when the adult squeezes them with its claws and chewing them with its beak. Pigeons can be very troublesome. They mess with their droppings, the…

E: The carrion niche

…n. Milk, which is a thin suspension of animal fat and protein, can attract common houseflies and blowflies, when it becomes sour and cheesy, and their larvae can develop in milk residues. Open wounds and infections – also in humans – can tempt blowflies to lay eggs. Pharaoh ants collect meat and can go into wounds. 2. Pests in dry carrion: Skin beetles (not the khapra beetle) copra beetles, spider beetles and various moth larvae play a major role…

The hen flea

…bird nests that sit under the roof, through draft ducts and similar areas. Household pets can also be the cause of an outbreak of hen fleas. Therefore, you must be careful if you keep chickens in the garden, and where you may inadvertently bring the fleas into the house. It may be difficult to find the hearth of the outbreak. Therefore, one should arm oneself with patience. The reason can also be as simple as that you pass the same abandoned nest…

Hoverfly

…are sometimes seen perched on flowers, particularly umbellifers, for they feed on the flower nectar and pollen, and play an important role in pollination. Their larvae are very effective consumers of aphids (greenfly), so in addition to being attractive hoverflies are also extremely beneficial, and with them in mind it may sometimes pay not to spray the garden with an insecticide. When hoverflies come indoors it is simply because the house, with…

Ground beetles

…ful butterfly larvae. The ground beetle has a special way of digesting its feed, namely by vomiting digestive fluid on its prey. The prey will thereby be paralyzed and liquify. In other words, the beetle does not need fangs or anything else to eat its prey. However, there are some species of ground beetles that are fully or partly herbivores. These species of beetles can attack fruits and vegetables in your home, and you should therefor keep an ey…

Ametastegia glabrata

…t occasionally they try elsewhere. When they attack wooden articles in the house they may become a nuisance. Very often they give up gnawing and try elsewhere, leaving a number of half-finished holes in the timber (see p. 117). It is very often new houses that are subjected to the attacks of these otherwise completely harmless insects. This may be due to the fact that the gardens have not yet been cultivated so that the ground is covered with the…

Museum beetles

…o find food. The larvae are specialists in regards to their own diet, they feed on the very last dry remains of dead animals where the other scavengers give up. That is cartilage, tendons, hair and feathers. It is useful work to get this dead animal material into the “circle of life” again, but it is this exact ability to digest wool and feathers that brings them into conflict with us. Favourable conditions are found in old birds’ nests where ther…

Mealworm beetle

…ollowing summer and die in the autumn. In former times mealworms were very common in bakeries, mills and grain warehouses, but nowadays they are no longer important as a pest. Mealworm beetle The adult beetles seen usually come from birds’ nests in the neighbourhood. On warm summer evenings they often fly in through the windows, attracted by the light. They normally do no harm in the living rooms of a house, and as they take so long to develop the…

Fleas

…depends largely upon the temperature and may vary from 8 to 150 days. The common flea species can be distinguished from each other on the brushes and hairs that sit on the head and chest When fully grown the larva pupates in 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 f…

Tanbark borer

…or damaged trees with a bark for the placement of her eggs, as her larvae feed on the bast layer between bark and sapwood. Therefore, it is also clear to see if a group of tanbark borer larvae have been at play in a tree. To remove the bark, their passages emerge clearly as small furrows in the wood. And you can even see small traces of the larvae’s cheekbones, which are marked as a faint streak. The passages are also full of drilling dust, which…

Aphomia sociella

…of pupae. The buttery yellow larvae of the bee moth crawl on the litter’s common web of pupa cocoons. They have gnawed their way into a white foam sheet These are commonly found, sometimes so firmly attached to the substrate that it is difficult to break them loose. The larvae may cause damage by gnawing the substrate to provide a suitable site for the communal cocoon, but otherwise they are completely harmless. The adult moths do not attack text…

Yellow-necked mouse

…the year out in the open, but some enter houses, usually later on than the house mice, about the end of October. They will eat stores of fruit in cellars or other places. In the wild, yellow-necked mice feed on all kinds of seeds and they are very fond of hazelnuts and almonds. They are primarily woodland animals, which have spread to gardens and parks with scattered trees and bushes. They are common in many parts of Europe and also occur in south…

Mold beetles

…lls creating a good environment to mold and mold beetles. It is also not uncommon for the mold beetles to appear in newer houses. Here the beetles will appear before the walls have dried complete. However, in these cases the problem will most often stop on its own. Damage Although mold beetles may look disgusting and seem harmful, they are practically harmless. They can however in rare cases, damage dried vegetable food stuff such as dried fruits,…

Bird fleas

…hrives in dry, high-lying nests and can also form large populations in hen houses. Bird flea larva can only develop in birds’ nests, where they feed on various organic materials. The adult fleas suck blood of birds. Bird fleas overwinter in the nests. During the autumn, flea larvae develop into adult fleas, but they do not emerge from the cocoon before the spring. The hatching process is sped up by vibrations made when the birds return to the nest…

Pigeons

…in the city, and which build nests in and on buildings, originate from the common domestic pigeons and are just stray pigeons. Although the pigeons stay in the city, it is important not to feed them as they are considered pests. Appearance There is a relatively large difference in the size of pigeons, depending on the type in question. The size of pigeons therefore ranges from 15 to 75 centimeters in length and from 30 g to 2 kg in weight. In gene…
