Flies, cockroaches, mosquitoes, lizards… These intruders sometimes show up unannounced and become a part of our daily lives. Rather than bringing out the heavy artillery of chemicals, why not opt for a solution that’s as natural as it is effective? An unexpected ally is hiding in your kitchen: garlic.
Yes, you read that right. This fragrant little bulb, the star of stews, can also become your secret weapon against invaders. Here’s how to use it to make your home a truly peaceful haven , “without danger to your health or that of your loved ones.”
Why does garlic repel pests?

Garlic’s effectiveness lies in a well-known component: allicin, a sulfur compound with a pungent odor. It severely disrupts the sensory system of insects and rodents. Where we simply smell a strong odor, pests perceive it as a “warning signal.”
The result? Flies, mosquitoes, rats, and lizards flee. By using garlic in targeted preparations, you create a natural olfactory barrier that’s harmless to both humans and pets.
