…. There is a sting on the back of the body, and it is with this sting that wasps stick. Although wasps are considered to be very aggressive, they only sting as a last resort. Wasps are relatively small animals. The larger wasp vespa crabro grows to a maximum of 2.5 cm long, but the typical size for smaller species is 1.2 to 1.4 cm. The worker wasps are typically between 11-15 mm long. The queen is somewhat larger and can grow between 14-19 mm long…

In social wasps, as in many bees and ants, the characteristic feature is a division of labour within the colony. Among the wasps the queens and males are occupied with reproduction while the workers build the nest, feed the larvae and defend the colony. Worker wasps are actually females with undeveloped reproducti…

The larvae are white yellow with three sets of breast feet, and at the tip of the hind body they have a short and dark thorn. Biology and behavior The appearance of this pest can be frightening to many and result in panic. Here, it is important knowing the difference bet…

Dusky cockroach The German Cockroach The German cockroach is hardly more common in Germany than anywhere else in the world. It lives in the wild in tropical forests. As a synanthrope species in colder regions it favours especially indoor environments that are both warm and humid. Outside the tropical forests the German cockroach lives in bakeries, greenhouses, hospitals etc. It spreads between houses by heat ducts. The forest cockroach tolerates…

In the German cockroach the female carries this egg capsule protruding from her genital aperture until the small, wingless young are ready to hatch out. At r…

Damage There are no parasitic wasp species that can damage furniture or houses. In fact, a variety of the species are used for biological pest control on farms, in plantations, gardens and greenhouses. Some species can sting with the laying brood, but this rarely happens. If this happens, it is usua…

The first sign that you have cockroaches in your house is quite large, slightly flattened animals with long legs and very long antennae that run into hiding when a light is turned on at night in the kitchen. The adult German cockroach is about one cm long, brownish with two dark stripes on the…

If you want to be accurate, you use the name hornet on the social species that belong to the family Vespidae. We have seven species of social, community-forming, hornets in Northern Europe. They are very similar and live the same kind of life. Only the big hornet Vespa crabro, that is twice as large as its relatives, stand out….
Wasps
Latin: Vespoides spp. Hornets – wasps Season 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 nes…

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…

Bees, wasps and ants
German wasp Bees, wasps and ants belong to the group of insects known as hymenoptera (Hymenoptera). Honey bee Many hymenoptera have sucking mouth parts, a tube with which they can drink liquid such as nectar. In addition, their mandibles are used to bite and chew, and for many of the hymenoptera, it is an important tool when they build their nests. Most hymenoptera are good fliers. They have two pairs of relatively short and narrow, clear wings,…

Colloquially, they are often called wasps, however, this can create misunderstandings, as th…

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, which is somewhat reminiscent of a wasp….
Wood wasps

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…

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…
