Leeches with what pesticides to remove? According to personal farming experience, the elimination of dry leeches rural people common methods are the following: pesticide spraying: generally not recommended; why so, because the effect of low-toxicity pesticides is not obvious, the special effects of pesticides will inevitably be a threat to the surrounding plants or crops, as well as water resources. Salt solution juicing method: dry leech this thing is very prevalent, it is soft and boneless, no skin protection, but the epidermis of the leech will secrete a layer of keratin membrane, when its body encounters the salt will make their own internal liquid outflow, until the body shrinks and dries up, and finally die. Remember when I was a kid, I used urine to滋leech it, the principle is the same.PH rot hair: also because of the dry leech special soft body physiological organization, encountered lime or soap this alkaline material, the body's PH value changes, so it will be a short period of time to ulcerate and die.

Methods to kill leeches:

1, wetland swamps, the most effective and harmless method of killing locusts is to sprinkle dry lime powder. Although killing with highly toxic pesticides is very effective, but there will be pesticide residues on the cultivation of people and later plants will also have an impact. The low-toxicity, low-residue "dichlorvos" is not very effective (it must be applied in higher concentrations). Therefore, lime is the most reasonable way to kill the locusts, when the locusts are contaminated with lime powder will fester and die, in the alkaline water with lime will also be physiological acid-base malfunction and die. The strong alkalinity of lime can only be maintained for a short period of time, after killing the insects can be diffused fade, fade is also conducive to the strong acidity of the old swamp soil has a very good role in improving.

2, the locust is a mollusk, no skin protection. Skin is the first protective barrier for animals, and locusts are very sensitive to salt because they have no skin. After spreading salt, salt and its body fluids to form a high concentration of brine, high concentration of brine will make it stress contraction, prompting its internal body fluids seepage, leading to its dehydration and death.

The treatment of locust bites:

1, locust bites, do not pull hard, it is easy to make the locust mouthparts broken in the skin and cause infection. Can be tapped near the bite, will be shocked off.

2, available soap solution, concentrated saline, tobacco oil, alcohol drops in its former sucker, or burning cigarettes hot, so that they fall off, and then press the wound to stop bleeding, and use iodine on the wound to prevent infection. You can also use tobacco juice, lime water, etc. to sprinkle on the locusts, or roast them with firewood to loosen them, or use a knife to scrape them off.

3, wounds such as constant bleeding, can be used charcoal ash into a powder compress on the wound, or with young bamboo leaves pounded on the compress.
