On the Danish islands of Bornholm and Zealand, the castor bean tick transmits tick-borne encephalitis of which there two sub-types in Denmark: The European encephalitis virus and the Far-Eastern tick-borne encephalitis virus. They can cause meningitis-like illness that particularly affects people who reside in forest areas. The disease is caused by a virus and can not be cured with antibiotics. The course of the disease is usually…

The castor bean tick
Fig. 65. The castor bean tick – ready to climb onto a host with the front pair of legs. (Gjelstrup) The castor bean tick The castor bean tick, Ixodes ricinus, is just one of about thirty kinds of ticks that are found in Denmark. However, it is almost exclusively this species of ticks that is found on humans. An adult male tick is approx. 2 mm long. The female is twice as long. Ticks engorge when they suck blood. The abdomen’s reddish-brown, leath…
Castor bean tick
Castor bean tick ( Latin: Ixodes ricinus) The adult male is 2 mm long, the female twice this .length, but these measurements only apply to individuals which have not recently fed. The red-brown, leathery skin of the abdomen can stretch to an incredible extent. This species is very common in some areas, but not in others. This is because it requires special environmental conditions. It is, for instance, sensitive to desiccation and is therefore fo…
Brown dog tick
…gy and behavior It is often the dog that is the recipient of the brown dog tick bite. Once the female tick has blood of its host, she releases the fur and instead seeks out a suitable hiding place nearby. The brown dog tick tends to seek upwards, which is why it is not uncommon to find them high up on the wall behind mirrors or pictures or inside cracks and crevices between wall and ceiling. Once the female has found a suitable place, she clings a…
Bean weevil
…feeds on dried goods, which is why it likes to attack foods such as dried beans, dried peas, lentils, and soybeans. It is also among these foods that the female lays her eggs. The female can lay up to 85 eggs. When the larvae hatch from the eggs, they go out into the world for food. This means that they gnaw their way into beans or peas, for instance. Here they go through their next three larval stages, which eventually results in the larvae pupa…
Ticks
…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 passing animals, where it bites. Once the tick has taken hold, it will remain in place for five to six days, after which it will fall to the ground and find a hiding place. Ticks are mainly active during spring and fall. During winter, the tick usually stays under moss or some other form of…

As evidenced, there are valid reasons why contact with the castor bean tick should be avoided. If you are bitten by the castor bean tick, be sure to remove it quickly. There are special tick pesticides that ease removal of ticks. A gentle spray of the ticks with an…
Pigeon tick
…s have lived for a long period of time can therefore be hearths for pigeon ticks. And if the residence is abandoned, the pigeon ticks may find themselves searching for new hosts to spy on. It is therefore not without precedent that the pigeon ticks have sought further into the dwelling and possibly tried to bite sleeping people. However, human blood is not a good starting point for pigeons, as they can neither survive for long nor multiply on this…
Ticks
…will find the same host the next time they need to suck blood. The castor bean tick and the brown dog tick must have a total of three blood meals (as larvae, as nymphs and as adults). The pigeon tick needs a total of five blood meals. The risk of not being able to find the next host is quite large. Ticks get by laying many eggs and by being able to live a long time without food. Three kinds of ticks can be especially troublesome: The castor bean…

Bean weevil Up to 28 larvae have been found in a single bean. As the common bean weevil is a member of the Bruchidae family, it is also subject to the import restrictions that apply to this entire family, see above. Common bean weevils are exterminated in the same manner as g…

The coffee bean weevil is actually not a bean weevil, but belongs to a family that stands near the true weevils. Therefore, it is not subject to the restrictions relating to bean beetles….

…rarely bites people. The species is widespread in warmer parts of the world. In Europe, it is mainly found in the Mediterranean. In Denmark, it is mostly seen on dogs that come from the south. In our parts of the world, the brown dog tick is found indoors. In appearance, it is similar to the castor bean tick. Usually, the circumstances under which the tick is found provide clues as to which species it belong. Brown dog ticks need to be controlled….
Brown dog tick
…it originally evolved in very dry climates, it is able, unlike the castor bean tick, to live and breed in centrally heated houses with a dry climate. Fully fed female dog ticks are scarcely one centimetre long when they leave the host, and this most often happens in the dog’s bed. Even in this condition they are surprisingly mobile and while searching for a suitable site for egg-laying they have a tendency to wander upwards. The 2,000-4,000 red-b…

European pigeon tick bites
…tick prefers to feed on pigeons. When in lack of a more suitable host, the tick may feed on people and pets. It’s almost exclusively the adults and nymphs that bite people. A bite from the large pigeon tick can be quite the experience. The bite is clumsy and can be painful. From the bite wound, a wide, pink, slightly swollen area may appear. Later, color will turn red or reddish-blue. Both the color as well the swelling can stay on the skin for up…
Suspected brown dog tick infestation
…. Silhouettes are in natural size. Ticks on a dog are almost always caster bean ticks that just need to be removed. Caster bean ticks lose the ability to find a host when the temperature drops below 7 °C. If the dog has ticks when it is significantly colder outside, it may be brown dog ticks. High levels of infestation in the house and ticks (especially blood-filled, gray females) on walls and ceilings may be brown dog ticks. Ticks that are found…

If the pigeon house is highly infested, the pigeons can be weakened and die from anaemia. In Denmark, the European pigeon tick has been known for some time, but it is not very common. European pigeon ticks live near the nests of domesticated pigeons, and they can reproduce heavily in old pigeon h…

…f pea and bean plants different granivorous weevils live. They infest the seeds already when the plants are in the fields and are later on transported to warehouses where they can continue to do damage. The result is seen as rotten peas, beans, lentils etc. Most of these weevils belong to the family Bruchidae and the species which are particularly harmful are found in the genera Bruchus, Acantoscelides and Callosobruchus.

Pigeon tick
…is is a bird parasite which may occasionally occur in the house. It is much larger than the red poultry mite and has a leathery, oval, red-brown body. The mouth parts are situated on the underside of the body and are not normally seen. Pigeon ticks which occur particularly in dovecotes have similar habits to poultry mites, but they can survive without food for a longer period. There have been cases where pigeon ticks have appeared 2-3 years after…

Fig. 68 The brown dog tick is rather similar to the castor bean tick, however, the male’s carapace is larger and in a non-blood engorged female, you can see a ruffle pattern on the trailing edge of the body. Look for ticks in the locations indicated by the arrows. The female lays 2000-4000 eggs at a time. The eggs reddish-brown and are placed in clusters high up on the walls, in cracks or behind paintings. The hatching time of the eggs is 19-60 d…

If the suspicion has been confirmed, you can treat the dog with a pour-on product in the hair – the same kind that is used against fleas, alternatively, you can use flea collars or treat the dog’s fur with a powder-based pesticide for dogs. Control can also be exaggerated. Using too many products at the same time can make the dog sick. When in do…

In the other Scandinavian countries mosquitoes are suspected of passing summer flu virus, etc. on to humans….
