3, it is best to wear light,smooth, tight-cut long-sleeved tops and trousers, wear shoes that can cover the entire foot, and tuck the pant legs into socks or shoes;
4. Spraying mosquito repellent (such as DEET) on the exposed parts of the body can be maintained for several hours;
5. When leaving the wild, carefully check whether there are ticks attached to the scalp, waist, ankles and other parts to prevent the ticks from being brought home.
What should I do if I am bitten by a tick?
1, if you find ticks attached to the body, do not pull hard. If it is forcibly dragged, it will drill the head deep into the human skin, easy to leave the head and claws in the skin, and it is easy to stimulate it to secrete a large amount of saliva to increase the release of pathogens.
2. Turpentine, ether or dry smoke can be applied to the head of ticks, so that ticks can fall off naturally, and disinfect the wound in time.
