Do flies ruin your summer?! Would you like to get rid of them? Here is an easy trick for that. All that you need is 3 lemons. Cut them in half and place them on the oven shelves and leave them there overnight. Make sure that the door is completely open. In the morning, close the door and turn the oven to 100 degrees. Don’t bake the lemon – simply wait for the pleasant scent to spread all over your home. Once the lemon gets really soft, throw it away. As a result of this, your home will smell like lemon for many days. Flies get irritated from this smell. Hence, they will stay away from your home.
