Garlic dipped in essential oil is a natural remedy that some people use for various purposes around the house. When hung in a window, it is believed to repel a variety of unwanted things, including insects and pests. The strong smell of garlic, combined with the potent aroma of essential oils, can create an effective deterrent. Here's a breakdown of how it works and the benefits:

1. Insect Repellent: The scent of garlic is known to be a natural insect repellent. It can help keep flies, mosquitoes, and other pests away from the house. When combined with essential oils like peppermint, eucalyptus, or lemongrass, the aroma becomes even more powerful in deterring bugs.

2. Purifying the Air: Some essential oils have air-purifying properties. For example, tea tree oil and lavender are known for their ability to purify indoor air and can help eliminate unpleasant odors in the house.

3. Natural and Chemical-Free: One of the biggest advantages of this method is that it is chemical-free. Using garlic and essential oils as a repellent avoids the use of toxic chemicals found in many commercial repellents, making it a safer option for households with children and pets.

4. How to Use It: To make the repellent, simply dip peeled garlic cloves into your chosen essential oil (such as eucalyptus or peppermint), and hang them in a mesh bag or a string in a window where the aroma can circulate. You can also place the garlic in a small dish or hang it in areas where pests are most likely to appear.

While this method may not be as potent as chemical alternatives, it's an eco-friendly, low-cost option for those looking to naturally repel insects and purify the air in their homes.
