How to Use ONIONS to Get Rid of Common Pests Naturally – Rats, Flies, Lice, Mosquitoes & More!

Did you know that something as simple as an onion can help keep your home free of unwanted pests? Onions have a strong smell that repels many insects and animals naturally — including rats, flies, mosquitoes, cockroaches, lice, bugs, and even lizards.

Let’s explore how to use onions in different ways to gently (but effectively) keep your space pest-free.


🐀 1. For Rats and Mice

How it works: Rats hate the strong smell of onion.

What to do:

  • Cut an onion in half.
  • Place it near entry points, behind appliances, or corners where rats may pass.
  • Replace the onion daily to keep the smell fresh.

⚠️ Important: Keep onions out of reach of pets!


🪰 2. For Flies

What to do:

  • Chop one onion and put it in a shallow bowl.
  • Add a little water and 1–2 teaspoons of clove powder (optional for stronger effect).
  • Place the bowl near windows or where flies gather.

The smell keeps them away!


🧼 3. For Head Lice (in humans)

What to do:

  • Blend 1 onion into a paste and strain to collect the juice.
  • Apply the juice to the scalp. Leave on for 30 minutes.
  • Rinse and shampoo well.
  • Repeat 2–3 times a week until lice are gone.

🐜 4. For Bugs, Lizards, and Cockroaches

Onion Spray Recipe:

  • Blend 1 onion, 1 garlic clove, and 1 cup of water.
  • Strain and pour into a spray bottle.
  • Spray in corners, under sinks, behind furniture, and near cracks.

This mixture acts as a natural repellent — bugs and lizards can’t stand the smell!


🦟 5. For Mosquitoes

What to do:

  • Rub a slice of onion lightly on exposed skin (only if your skin isn’t sensitive).
  • Or, leave chopped onions near windows to deter mosquitoes from coming in.

Final Tip:

Onions are a powerful, safe, and natural way to keep pests out — without harming your health or the environment. Simple, effective, and always available in your kitchen!
