Exit-holes in timber

…der beetles exit-holes in timber Larder beetles The larvae of many beetles and moths sometimes gnaw their way into timber when they are about to pupate. The pupal tunnels are gnawed from the outside and usually end blind, but if there are many of them the timber may be riddled with a labyrinth of tunnels. There is no wood dust in these tunnels, but empty larval casts are nearly always found. The pupal tunnels of larder beetles are circular in c…

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…

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…

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…

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…

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.

Bed bugs

…by body heat. They bite preferably on uncovered parts of the skin such as hands, arms, feet and neck, as opposed to fleas that often bites under close-fitting clothing. An adult bed bug eats 5-10 minutes and is then full. Then it pulls the proboscis back and crawls into hiding again. Here it sits and digests for a week until it gets hungry and crawls out from hiding again. People respond very differently to bed bug bites. Some people have severe r…

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

…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…

Wasps

…she lays an egg in each. When the eggs hatch, she must fetch food for the larvae, and only after the first litter of workers hatches about a month later, the queen can relax and concentrate on laying eggs. The workers are now taking over the work of expanding the nest and fetch feed for the new larvae. It is a vulnerable period and if the weather is cold, many queens die before they are finished with the work, and that means a year with only few…

Australian spider beetle

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…

Brown dog tick

…suck blood, grow spherical and become light gray. They then leave the dog and seek refuge again, and over the next 23 days the brown dog tick changes skin and turns into a reddish-brown nymph with eight legs. After the transformation, it is time again to suck blood from a dog. This time the meal lasts for four to nine days, during which the nymph grows larger and again becomes gray and swollen. Once again, the tick leaves the dog and seeks refuge…

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

The species which had the most chance of survival, and which have become serious pests of timber, were those which could thrive in dry wood, for this is what is used in houses. In addition, there are several species which occur in places where timber structures have been damaged by damp and by fungus. Identification of…

Bumble bee wax moth

…oes not refrain from attacking the larvae themselves in the nest. When the moth larvae have finished their development in September, they leave the nest, after which they move to a protected area nearby. Here they jointly spin a pupa, in which they pupate together. Such a pupae can hold hundreds of small pupates spun together from an incredibly strong silk. These pupae can appear in unusual places in the garden. And it is not unheard of to come ac…

Fur beetle

You treat against fur beetles, just as you treat against moths, by thoroughly cleaning the infested textiles. For certain types of wool, you can…

Ticks

…ar by animal tracks. The development of the tick consists of three stages: larva, nymph, and adult. A blood meal is required at each stage. The total life cycle of ticks is typically two to five years. The larvae are just ½ mm and suck blood from mice. The nymphs are 1 mm long and suck blood from mice and larger mammals such as humans, foxes, deer, and dogs. Adult tick also sucks blood from larger mammals. The tick climbs into vegetation and grabs…

Mole

…like Bornholm, Samsø, and Møn. A mole is an insectivore, just as hedgehogs and shrews, and it is something of a distinctive animal. Although they are useful in regards to the ecosystem, they can at the same time create a lot of damage in gardens and lawns, which is the most obvious reason why many people want to get rid of them. The mole is a powerful but annoying mammal, but useful, even when they leave molehills all over the place. The moles eat…

Pigeon tick

…it clings for the first 2 to 10 days of its life. When it has finished its meal, the larva hides in hiding in a crack or crack no more than a few meters from the nest, where it moves to change skin. The larva goes through several stages – where it alternately seeks out its meals on the pigeon and seeks shelter to change skin – until it is finally fully developed as either a sexually mature male or female. If the larva ends up as a male, it only ha…
