What Are Leeches Most Afraid Of? Understanding Leeches' Natural Enemies in One Article
Leeches mostly live in freshwater, with some terrestrial and amphibious species, and a few live in saltwater; among them are species that live by sucking blood or body fluids, as well as carnivorous species that prey on small animals. Let's take a look below at what leeches are most afraid of!
What are leeches most afraid of?
Leeches are most afraid of salt. Leeches are soft-bodied animals without skin protection. Skin is an animal's first protective barrier, and since leeches have no skin, they are extremely sensitive to salt. After salt is sprinkled on them, the salt forms a highly concentrated saline solution with their body fluids. The highly concentrated saline solution causes them to contract reflexively, prompting their internal body fluids to seep out, leading to dehydration and death. So if you are bitten by a leech in the wild, don't panic. Drop highly concentrated saline solution onto the leech, and it will quickly release its sucker, fall off, and die of dehydration.
What are the main natural enemies of leeches?
1. Rats: Rats are the main natural enemies of leeches and often devour large numbers of them, especially when leeches are active on the shore, where they lose their defensive ability and are eaten by rats.
2. Ants: Ants mainly harm leeches that are laying eggs and their egg cocoons.
3. Snakes and water centipedes: Snakes and water centipedes can sometimes swallow leeches.
What should you do if a leech sucks your blood?
First find the leech's front sucker (the end that looks slender in its overall shape), pry it off with your fingernail, then pry off the rear sucker. Be careful not to reverse the order above, and it will fall off on its own. After it falls off, clean the wound as usual and apply a bandage.
