Ticks are annoying and can sometimes spoil a walk in nature. We give you eight expert tips for dealing with annoying insects so that you can still enjoy your summer.
Hiking through nature in summer without thinking about ticks – that would be nice. Unfortunately, encounters with the animals cannot be avoided in many places during the warmer months.
Ticks transmit diseases such as Lyme disease or tick-borne encephalitis (TBE). What is the best way to protect yourself from the animals – and what to do after a bite? Two experts give tips.
“Our native ticks like to stay in tall grass, bushes, loose leaves and in forests that are not too dry,” says family doctor and emergency doctor Michaela Geiger from Neckarsulm.
Most of the time you brush them off in passing. “In this respect, the protective rules are: wear sturdy shoes, put long trousers in your socks and thoroughly check your whole body after spending time in nature.”
Children should also wear a hat. Because: Ticks can climb up to a certain height in the bushes.
It is also advisable to find out whether you are traveling in a TBE risk area. According to the Robert Koch Institute, there are currently 175 districts, most of them in Bavaria and Baden-Württemberg.
Mosquito or tick sprays are only useful to a limited extent, says tropical medicine specialist Kristina Huber from the LMU Klinikum in Munich. “They are good against mosquitoes – but it has not been proven that they are just as effective against ticks.”
A combination of different measures ensures the best possible protection: a vaccination against TBE, long clothing, a tick spray with the active ingredient permethrin – sprayed on the skin and fabric.
Just as important as the preparation is the follow-up – i.e. the thorough examination of the body. Important: “Since you can’t see the back and the back of your knees so well, it helps to support each other when searching,” says emergency doctor Geiger.
You should also not forget the body folds in the genital area as well as the areas behind the ears and under the armpits.
“A tick, which is usually dark, is easier to spot on light-colored clothing,” says family doctor Geiger.
By the way, if you dress in bright colors in nature, you can also keep mosquitoes that are active during the day at bay. According to Huber, a specialist in tropical medicine, they tend to respond to dark colors.
What if you were bitten by a tick? The advice of emergency physician Michaela Geiger: keep calm. “You usually have enough time to remove the tick.”
In the case of Lyme disease, the tick has to suck on the skin for a certain amount of time before it releases Borrelia to the human organism. “If you remove the tick in less than twelve hours, you usually have nothing to worry about,” says Geiger.
It looks a little different with TBE. The disease is transmitted much faster by a tick bite. But it is also much rarer: According to the RKI, only 0.1 to 5 percent of ticks in risk areas carry TBE viruses.
As a rule, however, there is time to go to the pharmacy to buy tools to remove the tick. Advantage of tick hooks, cards or pliers: Thanks to them, the tick can be removed slowly and in a controlled manner. It is best to disinfect the wound afterwards.
Sometimes you don’t have any special tools at hand – and there is no pharmacy nearby either. It is better to stay away from home remedies.
Kristina Huber gives an example: “It used to be said that you should rub oil or butter on the tick so that it couldn’t breathe anymore and had to let go.”
According to the infectiologist, this is true, but there is a risk that the tick – if it brings TBE viruses or Borrelia with it – will spit out the pathogens through the friction. “Therefore, this method is strongly discouraged,” says Huber.
In an emergency, the tick can also be removed with your fingers. “It is important not to squeeze or twist the tick, otherwise it is more likely to release pathogens into the human organism,” says Geiger, who is also the chairwoman of the German Central Association of Homeopathic Doctors (DZVhÄ).
“Many are afraid that they have removed the body of the tick, but its head or stinging device is still in the skin,” says the doctor. The same applies here: no reason to panic. Because the transmission of Borrelia via the head alone does not work – these are in the gut of the tick.
If you are not sure that you have removed the entire tick, you can consult your family doctor to be on the safe side.
“If you have been bitten by a tick, it is fundamentally important to observe the area for four to six weeks,” says Michaela Geiger. You can note the date of the sting and mark the puncture site.
In this way, the local movement of the inflammation can be easily tracked. “Sometimes you get stung and the skin turns a little red at the site, which is perfectly normal,” says Geiger. The redness often disappears after a few days without an infection having occurred.
By the way: Lyme disease and TBE symptoms can be easily distinguished from each other. In the case of Lyme disease, the so-called reddening occurs as the first sign.
“The puncture mark in the center is fading. An expanding red halo is created around it,” describes Geiger. The edge-accentuated circle can increase up to a diameter of 10 to 20 centimeters. Lyme disease can be treated well with antibiotics.
According to Huber, a TBE infection usually begins with non-specific symptoms such as headaches and body aches or fever. There is often a symptom-free interval of almost a week before meningitis, brain or nerve inflammation sets in.
Many may have already read about her – the Hyalomma tick. But is it really on the rise and also a danger in Germany?
The Hyalomma tick is mainly found in tropical countries. In Europe it is mainly reported in southern locations in particularly hot summers. “They migrate by attaching themselves to migratory birds – that’s how they get to Europe,” says tropical medicine specialist Huber.
The Hyalomma tick is significantly larger than native ticks and has striped legs. “In Germany, they are extremely rare,” says Huber.
So there is no need to worry. In this country it is still very likely to be bitten by one of “our” ticks, says Huber.
