Wasps

…kill large prey with their sting. The part the prey, and chew it to round feed buns. They can also cut chunks of carrion or retrieve small pieces of roast from lunch tables. When they feed the larvae with these meat buns the larvae regurgitate a drop of a sugary substance. The adult wasps eat this. It gives them energy and perhaps even motivation to care for the larvae. That is the summer in the wasps’ lives. Their community continues to grow and…

Brown house moth

…Under favourable conditions the female can lay 500-600 eggs and the larvae feed on many different types of material. They are found in stores of cereals and seeds and may attack practically any kind of vegetable matter. They also gnaw woollen goods, often causing severe damage. Seed moth larvae have gnawed at a leather strap in a damp magazine The larvae are sometimes found in birds’ nests where they feed on food remains and on the nest material….

Ants

…ound, under stones or tiles that receive a fair amount of sunlight. Inside houses ants will usually settle in a cavity wall or under the floors. The common black ants are species which are highly dependent on aphids whose sugary excrement constitute an important part of their diet. They can take care of and protect aphid colonies against larvae of hover flies, ladybugs and other of the aphids’ enemies. In some cases, they may even build “stables”,…

House mouse

…(Latin: Mus musculus) Many house mice spend the summer out in the fields, but usually not far from houses. Then from the middle of August onwards they start to move indoors again, and the peak of such an invasion will usually be in the middle of September. See also p. 84 for more details on house mice. House mice seek indoors in the autumn…

Crickets

…ame from North Africa. In the past, bakeries were the typical residence of house crickets. Today it has become a common insect in homes, where it mainly lives in boiler rooms. In food businesses, you can find it in boiler rooms, heating ducts, and warm, moist production facilities. House crickets eat almost any kind of organic material, and have a certain fondness for soft things (vegetables, fruit, flour products and meat). The sharp, biting mout…

(8) The pharaoh ant and the common black ant

…oors, but in cases where a colony is located below or adjacent to a heated house, the slightly higher temperature can cause the ants to become active earlier in the spring than it normally would. It forces the common black ant to find its food indoors until it gets warmer and aphids appear outside. The above mentioned examples (1) – (8) show that Synanthropy both qualitatively and quantitatively is made up by the interaction between the biology of…

Itch mite

Itch mite (Latin: Sarcoptes scabiei) This mite lives actually in the skin, burrowing tunnels in the upper layer, rather like a mole. It is only 1/3 mm long and is rarely seen, but its presence is revealed by the inflamed and eczema-like condition it causes (see p. 52). The eggs are laid in the burrows made by the female and it takes a good two weeks for the young to reach the adult stage. Infection is usually by females with eggs being transferre…

Cheese mite

…ese mite ( Latin: Tyrophagus casei) Cheese mites can also live in corn, flour, etc., but they are best known for their occurrence in cheese, in which they gnaw small holes. A ripe, mite-infested cheese will be more or less covered with a grey powder, which consists of the mites themselves and their moulted skins and faeces. Cheese mites can live at low temperatures but not in the refrigerator. For many cheeses the presence of mites is highly undes…

The canine follicle mite

Snails in the house

…avior Both the cellar slug and the great grey slug can be found near or in houses, shacks, basements, and the like. They are primarily nocturnal and will only appear on dark days or during the night. In daylight they hide in humid places. Both species are omnivorous, and they feed on dead animal material, and plants. When the snails lay eggs, this is done during the summer. The eggs are quite large and are laid in clusters under boards, stones, an…

Common cluster fly

…lden and hairy. Appearance Cluster flies are slightly larger than ordinary houseflies. Instead of the metallic, shiny appearance that houseflies have, the cluster fly has a distinctive forebody with small, golden-yellow hairs. Together with a hind body that has light but irregular drawings on it, this gives the cluster fly a lighter appearance than the darker, shiny flies that you typically see. You can also tell the difference between the cluster…

House martin

…Latin: Delichon urbica Silhouette of house martin In the wild house martins build on cliffs but many make use of buildings. They always nest on the outside of buildings, often in small colonies, but occasionally there may be hundreds together. They build high up, rarely less than 3 m from the ground, and the nest which is constructed of mud is completely enclosed with a small entrance hole at the top….

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…

Control of timber pests

…. In some parts of Europe houses can be insured against the attacks of the house longhorn and if an insured house is at- tacked the insurance company has to undertake the necessary repairs and control measures without cost to the owner. Even though the responsibility lies with the insurance company it is nevertheless advisable to watch for the house long- horn because it invariably causes great inconvenience if the attack is widespread and a compr…

…they are marked by longitudinal ridges and their ends are more truncated. Common house mouse excrements House mouse droppings are cylindrical, and usually 6 mm long and 2.0-2.5 mm across. Excrements from yellow-necked mouse Yellow-necked mouse faeces are relatively short and thick in comparison with those of the house mouse. Excrements from brown rat Brown rat droppings are cylindrical, usually with blunt ends, and they are 17 mm long and 6 mm ac…

Rats

…at. They are between 16 – 23 cm long, and their tail is between 18-25. The house rat’s tail is, unlike the brown rat’s, longer than the body. The excrement of the house rat is usually 1 cm long, and more curved than the excrement of the brown rat. Biology and behavior Rats live together in nests. Here they can reproduce all year round if the temperature is warm enough. They multiply quickly inside buildings, where there is heating. The average fem…

Black garden ant

…ll, containing the remains of dead ants, and empty pupae. In Denmark it is common to have garden ants visit houses, they rarely destroy anything. The black garden ants do not have the ability to undermine the house. When they do build their nest in or near houses, the wood has been damaged in advance by moisture. However, damage can occur in the woodwork if the anthill materials touch wood. It is important to know that there are other species that…

Bed bugs in animals

…ears from the house. Bat bugs, Cimex pipistrelli, live in places where the Common pipistrelle sleep. The common pipistrelle is a species often settles in attics of residential houses, and the bed bugs may suddenly appear in living rooms. Bats are a protected species and cannot be eradicated. If you are bothered by the bats in your house, you should the Danish Zoological Museum. A treatment of bats’ hiding place (when they left, are out, or have be…

Common flower bug

Common Flower bug ( Latin: Anthocoris nemorum ) These are common bugs normally seen outdoors on trees and bushes, where they live by seizing aphids, mites and other small invertebrates, from which they suck the body fluids. They are often seen when one is picking fruit or they may be taken indoors on cut flowers. The proboscis is long and thin and the insect often bites humans. In many cases the bite is quite painful but normally there are no aft…

Biology

…kin surface. Two days later, the first egg is laid. The rest of the female mites’ life is spent laying eggs. At the same time, the mite is digging its way through the skin, digging 0.5-5 mm each day, the burrows may be several centimeters long. The female itch mite is not bound to her burrow. She can choose to move away and start a new burrow elsewhere on the skin. The development time from egg to egg is between two and three weeks. There is a hig…

Fur mite bites

…lets that are actually transformed claws. When the stylets pierce the skin, they form a small tube. The tube may be inserted into the skin like a cannula. It does not go deep into the skin, only 10 -20 micrometers into the stratum corneum. This is the reason why fur mites cannot suck blood. External digestion Saliva is injected into the skin through the small tube. When the enzyme-containing saliva has dissolved the tissue around the stylets, the…

Allergy to pests

…id working with these goods. Many people suffer from allergic reactions to house dust mites and will therefore also react to any small amount of mites in dusty foods. The house dust mites that cause allergic reactions do not live in food, but they share the same allergens with the mites that do. It is those shared allergens that people react to. As far as we know today, there is no particular allergen-risk by eating or drinking food containing pes…

The european pigeon tick

…ages, the larvae are less than l mm long. All stages are blood-sucking and feed on pigeons. In a pigeon house the European pigeon tick is a nuisance. If the pigeon house is highly infested, the pigeons can be weakened and die from anaemia. In Denmark, the European pigeon tick has been known for some time, but it is not very common. European pigeon ticks live near the nests of domesticated pigeons, and they can reproduce heavily in old pigeon house…

Dermestes lardarius

…fore pose a great risk of damage, as it can destroy crops or equipment. In houses, the Dermestes Lardarius can also do damage. However, not to the same extent as in, for instance, seed or feed stores. If a Dermestes Lardarius shows up in the home, there is a good chance that it has evolved into food or feed. But it is also likely to have evolved from larvae into a dead mouse under the floor, into a pigeon in the attic, or into a dead bird outside….

Skin beetle

…e. As described, the beetle places its eggs in places where the larvae can feed on the material. This means that dead animals, dry food, or rubbish bins can often be the cause of the beetles’s appearance. In the house, the beetle will probably originate from a pigeon nest in the attic, dead mice or rats under the floor or a dead bird in the ventilation system. Be sure to remove and destroy the source, thoroughly clean the area around the site and…

Yellow shadow ant

…out for traces of the yellow shadow ant. And here, a dark staining of delimited floor sections can be a good gossip handle for whether there should be an ant colony under the floorboards. At the trail of flying ants in the house, one should also be on guard. Control of the yellow shadow ant is best tackled by locating the ants’ nest and removing and destroying their nests. Here, a dark staining on the floor as described can be a good indicator. T…

Sounds

…eus can often be heard gnawing beneath the bark. Callidium is particularly common in the bark edges of, for example, roof timber made of softwood, while Phymatodes occurs in fire logs of birch and beech. The larvae of the house longhorn can also be heard from time to time, particularly on warm summer days when they are most active and their appetite reaches a peak. Normally a larva will feed for 5-10 minutes each hour and rest for the remainder of…

Hercules ant

…one will not be in doubt as the ants like to make trips in and out of the house. If you find or suspect that the house is infested with herculean ants, you should first contact your insurance company. The best way to get rid of the ants is to find the ant nest itself and destroy it. But it can be a difficult task and often it will not be enough to take the fight against the ants into your own hands. It usually requires the help of a professional…

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…
