Killing Rats With Salt And Detergent (Effective Way Or Not)

Killing Rats With Salt And Detergent

Killing rats with salt and detergent is a tried and tested remedy that is incredibly effective and easy on the pocket.

The reason that makes salt a better option for killing rats is that salt is a dehydrating agent. It causes severe loss of water content if given in large quantities. The long-term ingestion of salt in high doses will lead to organ failure.

Now the question arises, what happens if a rat eats salt?

Salt is incredibly deadly for rats compared to humans because the daily salt requirement for rats is between 0.3% to 0.5%. For this reason, rats don’t prefer salty foods as anything above this ratio will cause an abrupt stop in their growth and cause kidney failure.

To improvise the killer potion, add detergent with the salt. This potion will instantly kill the rat. Detergents have strong acids added to them, which are lethal in themselves. Together with salt and detergent will progress the process ten times faster.

How To Get Rats To Eat Salt? 

Typically, a rat would eat anything accessible to it, so getting a rat to eat something salty is not a big issue. 

  • To prevent the risk of suspicion, make a bulk salt and detergent solution and mix it with various foods. Large quantities will dilute the salt within the food.
  • Another recipe for getting rats to eat salt is to grab a small box and add salt, detergent, sugar, and flour. Mix it vigorously till it becomes a thick, murky paste. Increase the sugar quantity.
  • For choosing the right bait, cheese is the top-rated option. What kind of rat doesn’t like cheese?
  • Water sources should be blocked for the rats to have acute salt poisoning.
  • Besides cheese, a scented meat bone or specific rat food will also do your job. 

The key is ensuring that the rats eat above 80 grams of salt and have no water access. This will cause intense dehydration, and rats will die within a day.

Benefits Of Using Salt To Kill Rats

Several methods are now available in the markets for killing rats. But the problem with these methods is that some are not effective while some are expensive.
