1. Repel Cockroaches
Cockroaches are one of the most destructive pests in homes. They contaminate food, damage belongings, leave droppings everywhere, reproduce quickly, and are extremely difficult to eradicate.
However, if you pay close attention, you’ll notice that the presence of cockroaches diminishes significantly when onions are placed in the kitchen. The reason lies in the distinct odor that onions emit, which cockroaches find repulsive. Upon detecting this scent, they will steer clear and avoid venturing nearby.
The solution is simple: peel a few layers of an onion (preferably cut into small pieces) and place them in areas where cockroaches frequently congregate, such as cabinet corners, stove tops, or behind the refrigerator. This method provides a natural, safe, and effective means to deter cockroaches.
2. Repel Mosquitoes and Insects
Not only cockroaches but mosquitoes and numerous other insects also detest the smell of onions.
You can easily craft a mosquito repellent bag at home. Start by taking a disposable medical mask and cutting off one end to create a small bag. Then, chop an onion and place it inside the mask. Use the cut ear loops to securely tie the bag closed. Now you have an effective “mosquito repellent bag.”
Hang this bag near entryways, windows, or bedside to repel mosquitoes. The onion’s scent will permeate the air, creating an environment where mosquitoes dare not venture, ensuring you a peaceful, undisturbed sleep.
3. Eliminate Fridge and Bathroom Odors
It’s quite common for refrigerators to develop unpleasant odors. If the smell becomes too strong, it can not only affect the flavor of your food but also reduce the appliance’s ability to preserve food.
To address this issue, simply place a few slices of chopped onion inside the fridge. The pungent aroma of onions can neutralize and eliminate unpleasant odors. Over time, the onion slices will wither and dry out, at which point you should replace them with fresh ones.
Onions are not only useful for deodorizing refrigerators but also excel at removing bathroom odors. Simply chop an onion and place it in a corner of the bathroom, and the unpleasant smell will noticeably diminish.
4. Deodorize Shoes
As mentioned earlier, onions are highly effective at eliminating odors. Shoes, especially during the summer, tend to develop an unpleasant smell after prolonged use.
While it’s impractical to wash your shoes daily, you can use onions to deodorize them. Simply wrap a few onion slices in a paper towel and place them inside your smelly shoes. The paper towel will absorb moisture, while the onion neutralizes the odor. Leave it overnight, and by morning, remove the onion—your shoes will be dry and odor-free.
5. Remove Rust
Utensils like scissors, knives, and fruit peelers are prone to rust due to oxidation. When faced with this issue, onions can come to the rescue.
Here’s how: sprinkle a little salt on the rusty area to increase friction, then cut an onion and use the cut side to rub against the rust. Within a short time, the rust will be eliminated, leaving your metal utensils shiny and as good as new.
