They belong to the longhorn beetle family, which is also called cerambycidae. The wasp beetle can be recognized by its distinctive and sharp appearance. The wasp beetle can also be recognized by its black and yellow stripes that run across its elongated body. Similar to the animal it tries to…

One simply sprays right up the entrance hole, which will typically be found at the bottom of the nest. After 10-15 minutes, the wasps in the nest are paralyzed and you can remove the nest. You can instead use insect powder for a hidden nest. You simply powder the entrance hole, and the wasps will then transport the…
Woodwasps
…l. They belong to the group of Hymenoptera, where you will also find ants, regular wasps, and bees. Appearance All these pests are characterized by their transparent wings, which consist of a small network of veins. There are two different species of wood wasps, which are frequently occurring in the Danish forests. The giant wood wasp (Urocerus gigas) can grow up to 3 centimeters long and the small wood wasp (Sirex juvencus), which is slightly sma…

They chew the fine wood splinters with their own saliva to form a superior paper with which they construct the nest, both the outer protective casing, which comes to resemble an oval football and also the hexagonal cells in which the larvae develop. The larvae have an exclus…

…pletely dead and hangs back as nothing but a hollow shell. The problem for wasps (hornets) in these latitudes is that they do not, like the honey bees, store food for the cold months, and then must start fresh every spring. Wasps rarely occur as pests and in most cases you can live harmoniously as neighbour to a wasp’s nest. But if you are allergic to their stings or they appear in large numbers in a nursery, or if there simply are so many that it…
Hornet stings
…tinger to remove. Because of its size and deep humming sound, the European hornet can seem threatening. Many feel that getting stung by this hornet equals certain death. However, it is not more venomous than its smaller relatives, but, naturally, it holds more venom. A rule of thumb is that a European Hornet sting corresponds to two of the smaller species’ sting. Moreover, most confrontations with hornets take place during the autumn when eating o…
Parasitic wasps
…species vary a lot in both size and color. Some are very small and just 1.5-2 mm, while other species are larger 15-20 mm. Color wise, they also vary, some are yellow-brown or metallic, while others are almost completely black, with various types of markings. If you desire to distinguish the species from each other, it is the size and color you have to look at. Biology and behavior When parasitic wasps are larvae, they live in or on arthropods as…
Wasps
…for wasps The wasp is a wide category that covers digger wasps, parasitic wasps, hornets etc. Wasps are well known in their black and yellow striped abdomens and no less for their ability to sting. In Northern Europe there are about a dozen species of social wasps, which are very similar to each other both in way of life and appearances. At our latitude wasp colonies are annual. This means that the nests are only used the year they are built. Old…
Wasps and hornets
wasp and hornets A wasp uses its sting for killing prey, but it can also use it very effectively as a defensive weapon. The sting has associated glands which produce venom. A hornet sting can be very painful, but is normally not dangerous, as the amount of venom injected is very small. In some cases, however, people do become ill after being stung by a hornet. This is due either to the venom being injected directly into a blood vessel or to the v…
Hornets (actual wasps)
Fig. 48. The German Wasp, Paravespula germanica. (Leclerq & Lecomte) Hornet, wasp In Denmark, there are seven species of social hornets. 6 of them are very similar to each other. They belong to the genera Paravespula and Dolichovespula while the species known as the European Hornet, Vespa crabo is more of a reddish yellow and twice the size of the others. Colloquially, they are often called wasps, however, this can create misunderstandings, as th…

The chalcid larva lives as a parasite on the beetle larva and eventually kills it. There are records of up to 95 per cent of the beetle larvae in roof timbers being attacked in this way. When the adult chalcids emerge they often find their way out through the old exit-holes of beetle larvae or…

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 confuse and paralyze the…
Wood wasps
(Latin: Family Siricidae) Wood wasp Great wood wasp Wood wasps only lay eggs in trees that still have their bark, so they are unlikely to enter a house, except in timber already infested. It would, in fact, be possible to buy furniture containing these larvae. There is no risk of these insects spreading in the house, and it is very unlikely that they will be present in such numbers as to weaken the furniture. However, they may well cause damage w…
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…

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. But the bumble bee wax moth also does not refrain from attacking the larvae themselves in the nest. When the moth larvae have finished their development in S…

If the carpet is long while the floor below has been damp, this is the perfect climate for the white-shouldered house moth and their larvae to live in. You can relatively easily get rid of white-shouldered house moth by drying out, freezing, or washing your textiles. There are also various insecticides and moth repellents specifically for the purpose, for…

It can inflict a painful sting with its short stinger if you accidentally squeeze it….

This resulted in the silos quickly becoming full of moths, beetles and mites of the sort that could be found in negligible concentrations in all flour. In the flour silos they got their big break because the silos were never emptied and cleaned. Something similar happens with pests in grain, where 9 out of 10 cases origi…

When adult horseflies reproduce, they stick their eggs to various moist surfaces, such as plants, blades of grass and particularly moist stones. From the eggs hatch such small larvae. The hatching larvae crawl into swampy soil, which is typically found in Denmark by masses of water such as puddles, lakes, and the like. The larvae ar…

Hornets often find suitable nesting sites in attics, cavity walls or outbuildings. In the autumn, the hornet society stops working. The hornets no longer feed the larvae. They roam around on their own searching for sweet stuff, and at this time, the risk…

They played an important part in the religion of the ancient Egyptians, and are mentioned in sever…

In such cases the sting• usually has associated glands which produce a venom, that is, a substance which even in very small amounts can kill or paralyse other animals or cause them pain. In view of the fact that people react so differently to bites and stings it is almost impossible to ident…

The winged ants seek towards light, they must be out in the wild to mate so you will find them on window sills and crawling in the curtains. This swarming takes place simultaneously from many communities in the area. The winged ants mingle with garden ants from other communities and mate. The synchronisation is…
