## What if you already have a pest control solution in your kitchen?
This simple ingredient, often used only as a seasoning, has unexpected properties. Its strong scent and natural ingredients make it a true deterrent to many home invaders. Learn how to use it to repel pests without chemicals.
## Why do pests hate onions?
Onions are rich in sulfur compounds, which are responsible for their pungent, eye-watering odor… but also repel insects and rodents. These compounds interfere with their nervous system or impair their sense of smell, causing them to avoid areas where onions are present. Furthermore, unlike pesticides, they pose no health risks to humans (though they should be kept out of reach of pets, as they are toxic to them).
