The effect of "dichlorvos" with low toxicity and low residue is not very ideal, so using lime is the most reasonable way to kill locusts. When the locust is contaminated with lime powder, it will fester and die, and it will also die due to physiological acid-base disorders in alkaline water with lime. However, the strong alkalinity of lime can only be maintained for a short period of time, and it can be diffused and desalinated after insecticide. desalination is also beneficial to the improvement of strongly acidic old swamp soil.

Therefore, do not panic after being bitten by leeches in the wild, drop a high concentration of salt water on the leeches, and they will soon release the sucker and fall down and lose water and die.
