Don’t toss out your onion skins. Here are 11 ways to use them at home

Onion skins can be used to make a natural pest repellent for your garden. To prepare, soak a generous amount of onion skins in water for a few days, creating a concentrated solution. Strain the liquid and pour it into a spray bottle. Use this onion skin spray on plants to deter pests like aphids and spider mites. The strong scent of onions acts as a natural deterrent, helping to protect your plants without the use of harsh chemicals. Reapply as needed, especially after rain or watering.
