The Surprising Effect of Leaving a Fresh Onion Outside Your Door

Take a fresh onion and place it outside your main door or in a spot that needs refreshing.
Ensure it’s left whole and not cut, as a cut onion may spoil quickly and attract insects instead of repelling them.
Replace the onion every few days for optimal results.
A Note of Caution

After use, do not consume the onion. It may have absorbed bacteria, impurities, or toxins from the air, making it unsafe to eat.

Conclusion

Leaving a fresh onion outside your door may seem unusual, but the potential benefits—from purifying the air to repelling pests—make it an easy and natural trick to try. Whether it’s an old wives’ tale or a scientifically sound practice, the results might just surprise you!
