Mining bees

…its yellow and black stripes, elongated, pill-shaped body and transparent wings. However, mining bees are generally smaller than ordinary honeybees, but a few species are the size of honeybees. In terms of color, some of them may be roughly the same shade as honeybees, while others have a darker, yellow hue. In addition, some of them are more hairy, so you could confuse them with very thin bumblebees. However, by far the fewest Danes have an eye…

Control

…e narrow. (Chinery) If you know where the nest is, you can move around the house without making the hornets nervous see, you can live with a wasp’s nest in the house or garden. In many cases, it is impractical; especially there are children in the house. Then eradication is necessary. A free-hanging hive can be neutralized by spraying an insecticide containing pyrethrin I and II + piperonyl butoxide into the entrance hole. The pyrethrins instantly…

Bark beetle

…female will dig herself in between the back through a passage – called the mother passage – where she lays her eggs. These eggs are laid in small dents and pits in the passage. Once the eggs have hatched, the larvae take over the work themselves. The larvae gnaw their own small passages from the mother passage. The small bark beetle larvae live mostly on the liquid that comes from the tree and which leaks into the passages. This is a real meal for…

Clytus arietis

Preferred common name: The wasp beetle Clytus arietis With its eye-catching drawing and restless behavior, the wasp beetle corresponds well to its name. The larvae of this beetle live in dead, dry deciduous wood. They do not attack timber indoors, but may be introduced with logs, and when the adult beetles are flying in mid-summer, they sometimes come in through doors and windows. They attract attention because of the striking colour pattern, whi…

Footprints

…insect has six legs and there is really no chance of identifying one from its tracks alone. The most that could be deduced would be an idea of its size, and whether it left distinct tracks as it ran around or merely a few signs of creeping such as would be left by a larva. Mice and rats have four well-developed toes on each forefoot, while the considerably larger hind-feet have five toes. It is not possible to differentiate the various mouse spec…

Louse flies

…tened body instead of a spherical or egg-shaped body that most flies have. Its skin is also leathery instead of the familiar, metallic-shiny surface of many flies. The louse fly has strong legs. Unfortunately, there are several species of louse flies, such as the lizard fly, also called Crataerina pallida, and the swallow bite, also called Crataerina hirundinis, which cannot fly. This is because their shape has evolved to be parasites on birds and…

Tribolium destructor

…opment from egg to adult beetle takes about 3 months. The adults have an incredible wanderlust and so they may be found far from the kitchen. The beetle itself can live for more than 3 years, and can survive for months without food….

Ladybugs

…feed on aphids during the warmer months. But they can also be found in fruits when the weather starts to get colder. The Harlequin ladybug is more aggressive than its native cousins, which can lead to biodiversity problems. If the harlequin ladybug eats too much of the food that the two-spotted and seven-spotted ladybird should eat, we may risk losing our native ladybug to this more aggressive species. Damage Beside the worries that the presence…

Grain weevil

…eetle has usually come from the remains of a store of grain, but if this is not the case it will nearly always have originated in a packet of bird seed. Because of its rather specialized requirements this beetle is unlikely to become established in a private house….

Prevention of attacks by timber pests

…, it would be worth impregnating the new timber under pressure or painting its surface with one of the many insecticidal preparations available on the market. In the case of enclosed spaces, e.g. below some fiat roofs, there should always be a means of access so that the structural timber can be inspected for possible traces of infection. It is usually advisable to avoid timber with bark edges, as in some forms of panelling. Several very common ti…

Cat fleas

…to pupate. It typically takes 7 days for the adult cat flea to come out of its cocoon, but under adverse conditions it can take several months. The adult cat flea can now jump on fury animals and humans.  Although cat fleas are named after cats, dogs can also easily get cat fleas. In fact, cat fleas are more common in both dogs and cats than the so-called dog fleas, Ctenocephalides canis. There is a particularly high risk that both pets and humans…

Silverfish

…common, is the Lepisma saccharina, which can be up to one centimeter long with the silvery body. The other species is Thermobia domestica, known as the oven fish, which can be up to two centimeters long. This one is not as shiny as the ordinary silverfish. The silverfish has two long antennae and three tail wires. The tail threads are less than half a body length. Biology and behavior The silverfish thrives in humid environments. Which is why you…

Wasps and hornets

…nt hornet eating apple A sting in the mouth or on the neck can be serious, as the mucus epithelium may become very swollen, making it difficult for the victim to breathe. An ordinary uncomplicated sting can be treated with ammonia or alcohol or with a cold poultice, followed by an antihistamine ointment. If the victim becomes pale and feels unwell with giddiness and nausea it is advisable to seek medical advice immediately….

Martin bug

…Martin bug (Latin: Oeciacus hirundinis) This relatively small species is found in the nests of house martins and swallows, and sometimes in those of house sparrows and woodpeckers. It may occasionally be found in a house, particularly after young house martins have left the nest….

Animals in thatch

…beech marten sometimes finds its way into lofts (see p. 188); it does not, however, occur in Britain. It is difficult enough to proof a house against martens and particularly so when it has a thatched roof. The marten tears holes in the thatch with its claws, and the edges of the holes are therefore frayed. Rats Rats (see also p. 88) can also work their way through a thatched roof. In contrast to the beech marten they use their teeth and a hole m…

Sounds

…ay through the skirting-board, or will have heard it playing hide-and-seek with its mates up in the attic. On account of their size rats tend to make even more noise. They have a very disturbing habit of dragging large objects around at night, which has given rise to stories of poltergeists. The fact that rats are involved is betrayed by the shrieks and squeals which accompany their petty squabbles. Beech martens in a loft also make noises, partic…

Wharfborer

…holes of wharf borer beetles are irregular and oval. They can be confused with the house longhorn, but the wharf borer beetles only grow in moist wood, unlike the house longhorn beetles. When seen in a house this beetle may have come in from outside, having emerged from ships’ timber or wharves, and it also thrives in piling and in structural timber in damp cellars. It is not uncommon for such timber to be so damaged as to require replacing. The…

Thrips

…has emptied. Thrips are laid as eggs; the laying will typically take place without fertilization. The eggs will be placed in selected location with a laying tube that is a sawtooth and can penetrate the plant tissue in which the eggs are laid. Thrips find it difficult to fly, therefore they will only as flying pest on calm windless and warm days. Damage The pest can in some cases have serious consequences for plants and flowers, especially on orna…

Woodlouse

…g will make cabbage on the woodlouse, which will thereby become extinct by itself. They can then be removed with a vacuum cleaner.   Sometimes the reason for a large number of woodlouse can be a hatchery near the home. For instance, in a compost pile, garden waste, a pile of straw or the like. Such piles should be removed, which can remedy the problem. It may be necessary to resort to chemical treatments. And here an insect powder will often be ab…

Earwig

…se to the house. Luxuriant plant growth and compost heaps provide excellent quarters for them. The nuisance can be ameliorated by catching them in traps. Simply fill a flowerpot with peat or plant fibre and stand it with the bottom up. The earwigs will creep into the trap which can be emptied every morning….

Precautions against infestations by pests of textiles

…rge wardrobe. Nowadays, many materials and carpets are impregnated against moths during manufacture. This is done with toxic substances which are introduced during the dyeing process or in a special bath. The poison becomes incorporated in the wool fibres and it kills the insect larvae when they start to feed. If the treatment has been effective there should be little damage before the insects have acquired a lethal dose. Control of textile pests…

Furniture beetles

…are very small and brownish with an almost cylindrical body. It is typical that the thorax is arched to form a hood which almost conceals the head. The larvae of the different species of furniture beetle are soft, curved, with very small legs, and they are difficult to distinguish from one another. They are known colloquially as woodworms. During the mating season the adults communicate with each other by banging the thorax against timber…

Examination of raw materials and food on site

…ou will usually be able to see various pests better than in the grain pile itself. Thermometer measurements with remote equipment or, for lack of a better way, a hand stuck into the stack may disclose heat changes, which may be due to weevils and especially their larvae inside the grains. Green budding grains in the surface can be an indication that there is a place within this takes place a heavy perspiration. It may be a “warm pocket” with lots…

Occurrence

…ible to do one time for each individual louse in its lifetime. That is why white people lice are dirty-white or grayish color. Lice on black people are dark and the North American Indians’ lice are reddish. The lice also make more permanent adjustments to the scalp hair, found in different human races. Hairs on black people have oval cross section. Lice on black people are so well adapted to grip the hair that they cannot live in Scandinavian hair…

The yellow-necked mouse

…ring 10-12 cm, and the tail is slightly longer than the rest of the animal. It is primarily associated with forests, but is also common in gardens with many trees and shrubs. Most of the year they stay out in the open, and the ones that invade houses do it towards the end of October. The yellow-necked mice continue to seek inside through the winter, apparently as the food in their natural habitats disappears….

B: The seed niche

…eetles, dark flour beetles and rice weevils as well as the larvae of brown house moths, Mediterranean flour moths and certain other moths. To them, flour, grains, baked goods and kernel damaged by granary weevils are just variations on the theme “damaged seeds.” The natural niches of these secondary grain pests are probably birds’ nests, where they feed on the spilled feed, when the birds feed their young. 2. Leguminous plant pests: Seeds of the p…

Booklice

…d winged booklice, e.g. Atropus pulsatorius, have small but non-functional wings. Booklice run about actively when disturbed, with characteristic jerky 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 s…

Horse-flies

How do they look?

…ned, and thus well suited to seek shelter in narrow crevices and cracks. The color is reddish brown and the body shape almost oval. The adult bed bugs are 4-5 mm long and 2-3 mm wide, which is a size you can see. It lacks the wings of a typical bug. The front pair of wings is reduced to a pair of small pads and the hind wings are completely missing. This means that the abdomen is exposed and you can clearly see its articulation. Males are consiste…

Bees, wasps and ants

…are good fliers. They have two pairs of relatively short and narrow, clear wings, and the hind wings are smaller than the fore wings. Bees, wasps and ants have slender waists in the front of the abdomen. They have “wasp waists”. It allows the abdomen to move freely, and helps the animals when they sting. With the exception of most ants and a few bees, most of the hymenoptera females have stings. It consists of three needle- or blade-shaped parts….
