What Smells Keeps Rats Away

Garlic is useful for more than just repelling vampires. It is effective against a variety of pests, particularly rats, raccoons, and deer.

Garlic’s greatest deterrent is its pungent odor. That is allicin. It is the chemical responsible for garlic’s characteristic odor.

Allicin, like capsaicin in chili peppers, is a plant defensive mechanism meant to discourage mammals from consuming it.

Onions, like garlic, possess a very distinct and powerful odor. This is because they contain sulfur-containing chemicals.

Some sulfuric chemicals, like allicin, emit a pungent scent that makes rats think long and hard about approaching.

You can use whole cloves to surround sensitive areas, but this can be expensive, and the cloves will ultimately decay and must be renewed.

Alternatively, create a spray with both garlic and onion:

  • 4 cups water, brought to a boil
  • 1 chopped onion and 2-4 garlic cloves
  • Turn the heat down and leave to simmer for 5 minutes.
  • Turn off the heat and allow the mixture to cool fully.
  • Fill a glass spray bottle halfway with water and strain the mixture.

Gently spray it all around rat breeding grounds.

Fresh and clean is a no-no for rats, so it’s no wonder that they despise citronella! Citronella is a strongly disliked fragrance among animals.

Because the scent is so powerful, it will overload a rat’s senses, making it nearly impossible for the rat to look for food and defend itself from attackers.

Citronella is so potent that a rat will flee it just because its inability to smell makes them feel insecure.
