How do you kill a leech after it bites, and why do some people still farm them?

The leech is what we call the bloodsucker, a common freshwater soft-bodied animal, usually found more often in farmland and in forests. Leeches suck blood, and if you are bitten by a leech and do not pay attention to how you handle it, it may have a certain impact on your health. So how do you kill a leech after it bites? Why do some people farm them?

1. How do you kill a leech after it bites?

If you are accidentally bitten by a leech while outside, your first reaction is to pull it off, but this way of handling it actually makes the leech bite down harder, because it has two large suckers. If you pull it off roughly, the leech's mouthparts will break off under the human skin and cause an infection. Generally, the fastest way to kill a leech is to slap the area around the leech bite with your hand; the continuous vibration will make the leech drop off. Of course, saline solution is also a method that can make a leech drop off quickly. Besides these two methods, you can apply alcohol, soapy water, vinegar, etc. to the spot where the leech bit.

If leeches appear in a large area, how do you kill them? The most effective way is to spray some dry lime powder, which will make the leeches' bodies fester and die.

2. Why do some people farm leeches?

Since leeches are so detestable, why do some people still farm them? Because the leech is a traditional medicine; after being dried, it can have a certain curative effect on bruises and injuries, high blood pressure, stroke, etc. Because of environmental pollution in recent years and the increased use of pesticides and chemical fertilizers, the living environment of leeches has changed, and wild leech resources have gradually decreased, so artificial leech farming has also gradually developed. At present, the purchase price on the market is also relatively decent, but any farming industry carries risks. So what do you need to pay attention to when farming leeches?

First, pay attention to preventing escape. If leeches are farmed in a pond and no escape-proof wall is built around the outside, it is very easy for the leeches to become fewer and fewer the longer they are farmed.

Second, pay attention to shading. Because leeches are very afraid of light, you can grow some aquatic plants in the pond, such as duckweed, water hyacinth, etc., which can provide a shading effect and are also good for leeches to lay eggs on.

Third, feed them reasonably. When farming leeches, you must provide sufficient feed. Generally, blood clots from livestock are relatively good food, but they must not contain salt. Remember, do not put the food directly into the water, but place it on a wooden block and let them crawl over to feed on their own.

Fourth, when introducing stock, note that you must not put the leeches directly into the pond. Instead, put them in a cooler place around the pond and let them slowly crawl into the pond, which can increase the survival rate.

Fifth, harvesting. Generally, October is a good season for harvesting leeches, and they should be caught separately according to size.

In summary, if you are bitten by a leech, remember not to pull it off roughly; you can handle it with saline solution or by slapping and shaking it.
