Leeches are often seen in rice fields. What are leeches afraid of?

Abstract: there are many leeches in the rice field. What if they are bitten?

Leeches are very common in daily life, especially when fishing in the river or washing clothes, and when transplanting rice seedlings in the south, they accidentally lie on their own bodies to suck blood, and people who are afraid of mollusks will be scared and panicked by leeches. In fact, leeches are not as terrible as imagined. Let's take a look at what leeches are afraid of.

How to do when being sucked blood by leeches?

I believe that when we were young, we all played slugs, like snails without shells. According to the old man, if you sprinkle salt on the slug, it will slowly melt away. As a result, the slug died slowly after countless attempts, not really. This example is to say that leeches, like slugs, are molluscs. In order to adapt to fresh and humid environments, the skin degenerates to a very thin extent. Sprinkling salt or dripping high concentrations of salt water can make the leeches lose water, promote internal fluid exudation, and then die.

If you are accidentally sucked by leeches in the wild, do not pull them out with your hands. This can only make the leeches suck more and more tightly. After pulling out vigorously, the sucker of the leeches will remain inside the skin, which is likely to cause infection. If there is no hyperosmotic liquid to "kill" the leeches, sprinkling them with soap and detergent water will have the same effect. If none of these things are present, the leeches will automatically fall off if they are roasted with fire and vibrate where they are bitten. Of course, wearing rubber shoes and trousers when working in the field, sticking them into the trouser legs or applying mosquito repellent in exposed places is the best way to prevent leech bites.

In addition to being afraid of salt water, soapy water, detergent water and fire roasting, leeches are also afraid of their natural enemies.

There are many natural enemies of leeches, including lobsters, fish, rodents, snakes, mosquitoes, birds, ants and so on. This small, unpleasant animal also lives hard in the natural environment.

Rats are the biggest natural enemies of leeches. When leeches move on the shore, they will come to the shore to have a good meal. Ants have a greater threat to the leeches during the spawning period and the eggs of the leeches. When the leeches lose their resistance when they lay eggs, the ants will lay their hands on the leeches. In addition, the eggs of the leeches are also the favorite food for ants.

Fish and snakes can prey on leeches in the water. although leeches are tenacious, they do not have a bone in the body, and it is difficult to pose a threat to fish and snakes. After being caught, they can only be used as delicacies for fish and snakes.

Finally, with the popular science of one of the world's largest leeches, in November 2013, the world's largest leeches were found in Malaysia, with a length of more than 1.5 meters. It is said that they can swallow a chicken alive, which is how much blood it takes to grow so big.

Here is science to promote agriculture, with you to grow knowledge.
