However, smaller leeches can sometimes drill into the vagina to cause vaginal bleeding, can also invade the urethra to cause urine pain or hematuria, and can drill into the nasal cavity when washing face in the pond, swimming or drinking unboiled water, causing intermittent nasal congestion, epistaxis, nasal pain, runny nose and a sense of wriggling in the nose.

What are leeches most afraid of?

Leeches are molluscs and have no skin protection, because skin is the first protective barrier for animals, and leeches are very sensitive to salt because they have no skin. After sprinkling salt, the salt and its body fluids form a high concentration of salt water, which will cause its stress contraction, promote its internal body fluid extravasation, and lead to its dehydration and death. You can also use cool oil, smoke water (that is, water soaked in cigarettes), salt (salt is extremely important in outdoor activities, it is best to take a small bag with you wherever you go), strong vinegar, alcohol (or liquor), chili powder, lime and so on to relax the sucker and fall off.

What are the varieties of leeches?

1. Wide-body golden leeches: wide-body golden leeches are the main breeding species in China at present, which mainly absorb the blood of animals, as well as plankton and mollusk larvae in the water, which are mainly characterized by large individuals, fast growth, high reproduction rate and easy fishing.

2. Sharp fine golden thread leech: there is a yellow longitudinal band on each side of the leech body, the ventral side is grayish yellow, and there is a band with dark brown spots on both sides, which feeds on water earthworms and insect larvae. Although the underdeveloped jaw can pierce the skin, but can not suck blood.

3. Japanese medical leeches: the Japanese medical vermiculite body is narrow and long, slightly cylindrical, slightly flat on the back and abdomen, mainly sucking human and animal blood, mainly fish and other animal blood in nature, not easy to raise artificially in large areas, and is mostly used in vivo in medicine. Not to process drugs.

4. Light-embellish golden thread leech: the light-moistened gold thread vermiculite body is slightly spindle-shaped, the front gradually becomes sharp and thin, the mouth hole is in front of its trailing edge, and the body is small, often feeding on snails (field snails, vertebral snails) and insect larvae, with small reproduction and low yield. it is not suitable for artificial large-scale breeding.

5. Clavicular leeches: the living habits and contractual functions of leeches are similar to those of wide-bodied leeches, and they are large in size, high in yield and easy to raise, so they can also be cultured on a large scale as an excellent breed of artificial breeding.
