Indeed, it is often very difficult to assign the spot one of the pests . "Sometimes you can see the bite ," says Tomas Jelinek, scientific director of the . "It is rather for larger insects so because they simply made a bigger hole . "
Most insect bites are harmless . Although it does not itch and unpleasant look beautiful , but are gone after a short time . The redness usually comes not from the violation by the bite itself - it is a reaction to the substances that the insect has injected into the wound. Kremer recommends to disinfect the bite with iodine or alcohol, and to protect it from dirt.
If the hives are in high spirits and dirt comes into the open position , they can become infected - a festering or severely painful wound is a possible consequence . Then it is better to go to the doctor advises Kremer . How dangerous is the inflammation , also depends on the place where it occurs. " At the hands and feet , the risk of infection is greater , also there is bad blood circulation ," explains the doctor . An inflammation of the head that goes inside, however is problematic because of the proximity to the brain.
Sometimes it is not the insect at the risk , but the potential pathogens that are transmitted in the bite. A mosquito bite alone is often not a problem - a tropical disease like malaria already . " You do not remember the sting , and that no matter where in the world, which has been transferred ," says Jelinek . Meanwhile, there are also mosquitoes in Europe , the pathogens can pass on: transmit tiger mosquitoes in the south about the viral diseases such as dengue fever .
Of tropical medicine emphasizes, however, that in Europe otherwise rather applies : "The mosquito bite is annoying , but usually not dangerous. " Outside the continent , however, it looks different. Here are malaria, yellow fever and dengue fever , the main hazards. Anyone planning a long trip , should become better acquainted with a travel doctor or travel health clinic which vaccinations are appropriate and how best to protect yourself from the insects there.
But not only outdoors , there are tiny stinging that leave itchy marks on the skin . Also in the hotel room or apartment you can hide hungry beasts : fleas or bed bugs , for example. As their name suggests, are bugs feel especially comfortable bedchambers , but they can also lurk behind pictures , wallpapers protruding edges or joints in furniture .
If you have a suspicion that a room is infested , you should check it through thoroughly . That means lifting the mattress and look for the animals and feces. " The bugs always sit together in groups ," explains Jutta Klasen , specialist vet of Parasitology at the Federal Environment Agency . They were as one to two millimeters small black dots visible. By human body heat and the fact that changes in CO2 concentration in the air, the bugs would recognize immediately : " Aha, there is a host , we can tap into . "
The stitches are barely distinguishable from those of other insects : a red , bloodshot point that is slightly larger than the pustule after a mosquito bite . « Suspect it if you have the stitches in places that are not normally exposed is ," explains Klasen - so if the needle is not at the bottom , which can out hatches under the covers , and is also accessible for mosquitoes , but to back and thigh , which are mostly covered.
Dangerous for the bites of bed bugs are not - these tiny transmit any diseases . Nevertheless, Restless sleep and itchy patches are reasons enough not to share with the beasts of the mattress. If that still happens on vacation, should wash his clothes and check the luggage. Is the plague in their own home , helps only a professional pest exterminator says Klasen . Some even tried to fight the bugs themselves . " This is quite an illusion - that they hide thoroughly .
