Mites are generally parasitic on the epidermis of some animals, such as cattle and dogs. They are usually as big as sesame, mung bean and soybean, and the worms are oval. When it doesn't suck blood, its abdomen is flat and its back is slightly raised. The adult is 2 ~10mm long. After full of blood, it swells like red beans or castor beans, and the largest one can be as long as 30 mm. The surface is leathery and the back is covered with a shell shield. Insects are divided into jaws and bodies.

Its pathogenicity is not very strong, but because it feeds on animal blood for a living, it often carries many kinds of animal viruses. For example, a typical "forest encephalitis" is mainly transmitted by ticks. If ticks carrying some germs bite people, patients may be infected with some viruses, which may lead to serious diseases.

The following methods can be used to remove:

1. Once ticks are found to bite people, you can smear alcohol on your body to make the dog's head relax or die. After a few minutes, take out the tick with pointed tweezers, hold the tick in your mouth and pull it out quickly. Or gently scald the exposed part of the tick with cigarette butts and incense heads, and let its head slowly withdraw by itself. Pay attention to safety when scalding ticks. Don't pull hard to avoid hurting the skin, or leave the head of ticks in the skin.

2. Flea spray can be sprayed on the infected part, and the dog beans will die and can be removed the next day. Spray flea spray on the infected area regularly to keep the area clean.

3. It is not advisable to forcibly remove the "dog beans" bitten on the skin. You can drop a drop of tincture of iodine, alcohol or ether on it, or bake it with a cigarette to make the dog bean fall off automatically, or you can prick its abdomen with a needle to make it fall off automatically. After the tick is taken out, it should be disinfected locally with iodine or alcohol, and the physical condition should be observed at any time.

4. Applying soapy water or sodium bicarbonate to the wound can relieve pain and reduce swelling.

Strengthen daily feeding hygiene management and regularly remove kennel garbage. Adhere to the principle of self-reproduction and self-support, and carry out dog physical examination (brushing, rubbing fur, etc.). ) and carry out tick control on imported or sold dogs to prevent ticks from being brought in or out. Check the dog's body and place every year in combination with the maintenance of the kennel or regular disinfection every week.
