Chalcids’ exit holes in timber close to furniture beetle’s Chalcids The exit-holes have a diameter of less than 1 mm (see arrow). They are always found close to the holes made by furniture beetles, on which the chalcids live (see p. 152). Common furniture beetles The exit-holes have a diameter ol 1.5-2 mm. This furniture beetle occurs in many kinds…

Bumble bee wax moth

…included in the name of the moth. For the larvae are often found in bumble bee beehives. But a bumble bee beehive is just one in a series of nests where bumble bee wax moth can make itself comfortable. They also like to settle in wasp nests or bird nests. In rare cases, they may even seek out a honeycomb. Inside the bumblebees’ nest, the bumble bee wax moth lives on the organic material found, such as the content of flower dust in the wax pots. Bu…

Methods of treatment in pest control

…light. Entomologists have for a long time used light traps for collecting moths and other insects, and in more recent years there has been an increasing interest in using this type of apparatus for insect control. Light traps operate in different ways. The light may come from electric bulbs or from tubes, and the capture mechanism may involve either sucking the insects into a container by means of an air current, or attracting them to an electric…

Plasterer bee

…can be difficult for an ordinary person to distinguish between a plasterer bee and a honeybee, or a completely different kind of bee. Which type of species that just flown past one really do not matter unless it stings. The plaster bee is in general not aggressive, although they have a sting. In a completely normal situation, however, there is not much to be afraid of when one crosses path with a plaster bee. Appearance A plasterer bee simply look…

Moths in textiles

…here they are where fur moth larvae seek cracks and fissures in walls and moldings, so those areas should also be treated. Infested woolen clothes should be treated by washing and drying, as this will kill both the adult moths, eggs, and larvae. You can also dryclean the cloth. Remember not to use insect repellant directly on your clothing, as it may cause irritation. Adult moths that are flying around should be controlled with insect spray so tha…

Long-tailed Silverfish

The brown house moth

…ment cannot be carried out if the humidity is below 80% constant. When the larva pupates and transforms from a larva to an adult moth, it happens in a brownish cocoon that has the shape of a torpedo. Under normal circumstances, only one generation of brown house moth will hatch per year. Damage As described, bird nests are popular targets for the brown house moth to settle. Here they can feed on the birds’ feed residues and nesting material. But s…

Honeybees

…at support and care from her males and staff who make sure to keep her well-fed and comfortable. The bees’ efforts for the queen ensure that she only must concentrate on one thing: namely, to produce her eggs, which she produces in large numbers. A queen can produce up to 2,000 eggs a day. A queen is not always firmly planted on her throne in her nest. A community of bees can form so-called “offshoots”, where the worker bees build some extra-large…

Moths in the food industry

…egularly and thoroughly, as spilled food can be enough food for many moths and moth larvae. Control should be done quickly and effectively when moths are detected in the food industry. Control of moths in the food industry typically takes place with pesticides and other poisons, which will make a whole batch of food unsaleable, as it is impossible to prevent the pesticide from getting on finished products and raw materials. Treatment with phosphor…

Mouse

…of all the destruction they cause and not just because the eat food stuff and candles. Beside eating from ones food stuff in the kitchen, the house mouse and the yellow-necked mouse can also bite in various textiles, such as curtains, padding, and bed linen, which is used in their nests. They do also gnaw in woodwork, which is used in their nests too. Not even cabels are safe; the house mouse and the yellow-necked mouse also bites into various el…

Mason bee

…an ordinary honeybee in appearance. It will not be possible to see a mason bee larva, as the larvae live all stages in the masonry nests. They pupate in this nest which is why we only see them as fully grown mason bees. Biology and behavior Since mason bees are solitary bees, the females lay their eggs in specially made nests. The female bee even creates this nest of whatever materials are available, like old snail houses, old tree stumps, sand sl…

Wasps

…op. The larvae have an exclusively animal diet, consisting mainly of flies and moths which the workers can catch in the air. The wings of the prey are cut off by the workers’ powerful mouthparts and the remains are divided up and chewed into round food balls, which are carried home to the larvae. The workers themselves feed on liquid food. They can be seen drinking nectar from flowers and the juices of ripe fruit, and curiously enough they are als…

Clothes moths

…ded when the larva has eaten all that it can reach from it Gnawed remnants and larval excrement sticking to the tube, and the presence of these webs is clear proof that it is the moths, and not other textile pests that have been gnawing. The development from egg to adult moth lasts from one month to over a year depending on temperature, humidity and food quality. Under normal circumstances in our homes, there will be two generations per year. Clot…

Mealworm Beetle

…eetle belongs to the family of shadow beetles (Tenebrionidae). Both adults and larvae are nocturnal. The adult beetles can fly and can be experienced in the middle of summer. The adult female beetle lays about 200 eggs during its 2–4-month adult life. The eggs are laid in starchy products, such as flour, grain, bread, and cereals. It takes a long time for the mealworm to develop; the development from egg to larva and to adult beetles can vary betw…

Wasps

…the larvae is meat. Wasps are hunters who catch flies, butterflies, honey bees and other insects in the air. They 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 eve…

Bed bugs

…ls can have problems and a common route of infestation is luggage that has been standing under the bed in a room with bed bugs. If you suspect that bed bugs have slipped into your luggage it is a good idea to review it on return. Clothes and other items that can tolerate it, should be washed in the washing machine or placed in a freezer a few days at minus 18 degrees C. Things that do not tolerate this treatment should be thoroughly inspected and…

Australian spider beetle

…ir own whitish cocoon in which they pupate. The cocoon has an almost tissue-paper-like appearance, and the webs of the larva can be seen as thin threads and spun cocoons in the infested area. The development from larva to fully adult thief beetle lasts about 3 to 4 months if the larva has good conditions e.g., at room temperature. When the larvae are fully developed, they most often leave this safe area. This means that they sometimes have to clim…

Indian meal moth

…hiny copper-red hind part. The larvae are characteristic with its yellowish-white color and a dark brown head. The larvae will typically be 12-13 mm long. This Indian meal moth is a well-known pest as it causes major problems in many countries, especially in warmer countries as well as in places where dried fruits, nuts and almonds are a tradition. However, you may also find them in grain and various grain products. The larva is well known as “wor…

Bread beetle

…and treats for signs so that any outbreak is not overlooked. Bread beetles and larvae can be killed by heating infected products at 60°C for about 10 minutes. It is also possible to get rid of the bread beetles by freezing, but it requires temperatures below -18°C for several days to get rid of all stages of the bread beetle, which is a lot more complicated. In addition, you can control the bread beetle with insect spray. Please note, however, tha…

Faeces

…ces out in the open and often on objects hanging from the ceiling. Clothes moth larvae produce faeces which can be found together with their silken threads in the places where they have been feeding. They are almost spherical, and have the same colour as the material on which the larvae have been feeding. The wood-eating larvae of furniture beetles, house longhorns, etc., deposit their faeces in the tunnels as what is known as frass. The appearanc…

Animals in timber

…h, for example, have large vessels. In some deciduous trees, such as birch and beech, the vessels are more uniform in size throughout the season, and are generally quite small. Normally the darker colour of the heartwood is due to waste products, such as tannins, and to some extent these serve as a protection against fungal infections and the attacks of various animals. On the other hand, the heartwood is not receptive to impregnation with timber…

Fur beetle

…indoors. A real sign of problems is when you observe several adult beetles and larvae in your home, including damage to your textiles, especially wool. If there are branches hanging over one’s roof where there are clear signs of bird nests, then remove the nest as soon as the chicks have flown from there. You treat against fur beetles, just as you treat against moths, by thoroughly cleaning the infested textiles. For certain types of wool, you can…

Brown dog tick

…s have eaten and is filled with blood, they are almost one centimeter long and the body has a gray-blue color, while their hind bodies are swollen. The brown dog tick is equipped with two pairs of mouthparts with effective hooks, which help the tick to adhere to the host animal’s skin. The upper jaws of the tick are shaped like sharp stilettos, while the lower jaws are shaped like a tube, through which the tick sucks up blood. Biology and behavior…

Bumblebee

…s to bird boxes and insulation materials in attics. It differs from species-to-species what types of beehive they prefer. Appearance The bumble bee belongs to the chubby end of the scale when it comes to bees. An adult bee grows between 15 and 20 millimeters long – and the queen slightly larger. The bees that hatch early in the season are most often the smallest. The bumble bee is available in several color variants, but has consistently yellowish…

Indian meal moths

…roduce silk, and silk threads in the infested items it is a sure sign that moth larvae are present. When the time of pupation approaches, the larvae become restless and seek out of whatever has been their home and pantry. In contrast to the adult moth they gnaw and they can easily gnaw through cardboard and plastic packaging. Usually they seek upward, and in this stage, you can see the larvae crawl up the walls until they find a suitable slot wher…

Drone fly larva

…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 to pupate. In so doing it may enter porches or cellars. The pupae are 10-12 mm long, grey-brown, almost oval, but they retain the long ‘tail’ and look somewhat like tiny grey mice. From the pupa emerges a hoverfly, but unlike those •already mentioned, this species is remarkably like a honey bee (see p. 31). Some hoverfly larvae…

Ticks

…ome 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 desiccation which is why they are found in forests and in low, dense vegetation. They are typically found in forests near by animal tracks. The development of the tick consists of three stage…
