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 insect spray containing pyrethrin I and […]
Life cycle
When the blood-filled female tick has let herself fall, she can lay eggs a few days later. About 2,000 eggs are laid. A reasonable number considering the poor chance of finding hosts. From the eggs, tiny, six-legged larvae hatch, and they are very hungry. They sit on blades of grass or the like. Here, they […]
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. […]
Ticks
Ticks are a kind of large mite that sucks the blood of larger animals. Ticks leave their host between blood meals and it is not very likely that they 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 […]
Control on the host animal
A.Washing the dog or cat with insecticides (for example shampoos containing pyrethrin I and II and piperonyl bubutoxid) kills the adult fleas that happen to be on the dog or cat while it is being washed. There is no residual effect that protects against the fleas that jump on to the pet after the treatment. […]
Control
An English zoologist has estimated that a typical cat flea population includes about 5000 fleas at various stages of development: 25 adult fleas are on the dog or cat. In the surroundings – mainly in carpets and in the animal’s sleeping place – there are 500 adult fleas, 500 cocoons, 3000 larvae and 1000 eggs. […]
Detection
Is your dog or cat scratching itself more than usual? Is it biting itself with its front teeth? Have you seen any fleas? Do the people who are in contact with the pets get itchy red bumps – especially at the ankles? Check for fleas in the pet. Regular flea inspection. Look closely in the […]
Flea bite allergies
About 10% of dogs or cats that have had fleas for a long time develop an allergy to flea saliva. You can see that something is wrong from the skin and the fur. There may be dermatitis or hair-loss. In other cases, there is an increased production of dandruff. The itching is severe and troublesome […]
Cat fleas bite people
You can get infested by cat fleas by being in contact with infested pets, or by being in places where infested pets are or have been. Cat fleas, however, prefer their natural host animals such as dogs or cats. Consequently, the family pet can have fleas without the other family members noticing. For this reason, […]
Cat flea biology
A female cat flea can begin laying eggs when it has mated and have been an adult flea for a few days. Usually, a cat flea lives for about a month and can lay about 200 eggs. The eggs are laid in dog or cat fur. They fall off the host, wherever it is. On […]
Dog fleas and cat fleas
The dog flea, Ctenocephalides canis and the cat flea, Ctenocephalides felis, belong to the flea species that bite humans in the absence of a more suitable host. The two flea species are similar. Dog Flea was once fairly common, but today, the cat flea is more common. Cat fleas can live on both dogs and […]
Human fleas
The human flea, Pulex irritans, was previously the most common flea inside houses. Nowadays, the chances of finding a population of human fleas inside a house are very small. In rare cases, human fleas can survive in damp houses where the larvae mainly live in creeks in the floor, in upholstered furniture or in damp […]
Many kinds of fleas
Danish flea species can be divided into groups according to the host animals: Human fleas, fleas on hedgehog, fleas on rabbits, bird fleas, fleas on bats, fleas on squirrels, fleas on mice, fleas on rats, fleas on foxes, fleas on badgers, dog fleas and cat fleas. Of these fleas, human fleas, hedgehog fleas, bird fleas, […]
General treatment
You cannot eliminate a flea problem by treating the person which has been bitten. Neither powder, nor sprays or ointment has effect in this regard. The only rational thing to do is to find the hot bed and eradicate the fleas, where they are found in the house. If the itching is so bad that […]
Flea bites
Fleas are mostly found on the ground or on the floor, and they will first and foremost attack ankles and lower legs. In contrast to bed bugs, fleas also crawl under clothing. Often they even bite in places where the clothes are tight. Bites during the night, especially on the thighs, buttocks and shoulders are […]
Eggs and larvae
Flea eggs are smooth, oval and grayish-white. They are about 1/4 mm long and can barely be seen as small grains on a dark background. The eggs are not glued to hair like nits, but sprinkles off the host animal, wherever it is. Flea larvae feed on various types of organic material, supplemented by the […]
The adult flea
Only adult fleas bite. The adult flea is elongated, 1-3 mm long and has flat sides. They look like small grasshoppers. The flea’s ability to jump is well known. An adult flea can jumps vertically up to 20 cm. Fleas are dark-colored. The head, the thorax which consists of three segments and abdomen are all […]
Fleas
( Latin: Siphonaptera ) Fleas (Siphonaptera) constitute an order of insects. Their biology is similar to that of flies. Some researchers believe that fleas were once a kind of flies, who lost their wings and adapted to a life as bloodsuckers on birds and mammals. Fleas are usually the most obvious possibility when insects bite people. […]
Ants
Approx. 100 million years ago, Ants (Formicidae) evolved from small solitary wasp-like ancestors. Some ants still have an actual venomous stinger like wasps. These stinging ants may attack if you accidentally sit on an anthill. There is usually no doubt about what the problem is. An anthill in the lawn can be eradicated by saturating […]
Other wasps
In addition to the social, real wasps, there are numerous solitary species. Some of them look like hornets (e.g. digger wasps and pompilids) and they can also inflict painful stings if you annoy them. Several species of small dark ichneumon flies may be found indoors. Usually, they will not sting people, but some species can […]
Control
If you know where the nest is, you can move around the house without making the hornets nervous see, you can live with a wasp’s nest in the house or garden. 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 […]
Prevention
You can avoid hornets settling into the house, by covering potential nesting holes with nylon nets. First and foremost, the gaps between boards in the eaves and vents in the walls need to be covered.
Hornet stings
Hornets are predators that use their stinger to overpower other insects. As you know, they also use it to defend themselves and their larvae. The stingers are not barbed, and can sting multiple times. Hornets do not sting when they are not provoked, however, especially in the immediate vicinity of the nest, they respond quickly […]
Black vine-weevil
(Latin: Otiorrhynchus sulcatus) This is one of the larger weevils. It moves around in a characteristic slow manner, and like all weevils it is vegetarian. The larvae live in the soil and feed on the underground parts of plants. The adults avoid the light and hide themselves during the day, often in the surface soil […]
Life cycle
Only young fertilized queen hornets overwinter. The queens wake up in the middle of April, and in May they start the process of building up new colonies. In late May, the first workers hatch, and from there, the colony size quickly grows. In August, there are up to 5000-6000 members of the colony. Until then, […]
Hornets (actual wasps)
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, […]
Solitary bees
In Denmark, there are a few hundred species of the so-called solitary bees. It is usually small, grayish or dark species. Most look like small versions of the honeybee. They are called solitary bees because they do not live in the colonies. Each female bee builds its own nest, lay eggs and gather food for […]
Control
In most cases, having a bumble bee family in the house poses no problems. They are, as mentioned, peaceful, and they make themselves useful by pollinating crops in the garden. In the rare cases when they are not tolerated, they can be controlled in the same manner as honeybees.
Bumblebee stings
Most bumblebees are so good-natured that people think they cannot sting. This is, however, not the case. Bumblebees have a powerful stinger and venom glands. By virtue of their size, the sting is painful.
Bumblebees
In Denmark, there is a dozen species of the usually big, strong and furry bumblebees of the genus Bombus. In contrast to honey bees bumble bee colonies only live one season. In the autumn all the workers and the old queen die. There are some young queens who – after having mated – goes into […]
