Why Do Onions Kill Rats?

For centuries, people have used onions to cook and as medicine. But did you know that onions also kill rats? Although onions are toxic to humans, the toxic components are broken down into less toxic compounds when cooked. Moreover, rats do not eat raw onions, so you can safely give them cooked ones.

Onions do not immediately kill rats, but their smell makes them flee. Rats do not like the smell of raw vegetables and would rather relocate to an area where the smell is more pleasant. In addition, rats would need to consume a very large quantity of onions to die. However, cooking onions reduces the toxins and brings the sweet flavor into the foreground.

In addition to being toxic to rats, onions also make it difficult for them to find food. If rats are trapped near onions, they would not find it easy to escape and would eventually die. Consequently, pet owners should be vigilant about what their pets eat. Onions are one of the most common ingredients in rat poison.

Rats’ olfactory senses are excellent, which means that they can detect a strong odor and quickly leave. When rats sense a source of food, they will search for an alternate entrance to enter your home.
