The battle to keep mice from coming into your home can sometimes feel like a losing one, especially if you live near fields or woodlands where they thrive. Keeping all your doors and windows closed at night, when mice are most active, can be helpful. But during the summer, it’s often far too hot to sleep in a tightly sealed home. And even with all the doors and windows shut properly, mice can still find their way into your home. They will take advantage of any gap or opening they can find to get inside and, once they’re in, are reluctant to leave again. Many people have successfully used vinegar and cotton balls to repel mice, where other methods have failed.
White vinegar is the most pungent and contains the highest concentrations of acetic acid – the stuff that gives vinegar its distinct smell. You can take advantage of its strong odour to deter mice from entering parts of your property. First, clean the area where you intend to use the vinegar treatment; wiping or mopping with clean, warm water will be sufficient. Next, you’ll want to coat your cotton balls in vinegar. Don’t submerge them or soak them entirely, not unless you want a powerful vinegar odour in your home. Make sure you wear gloves while you do this to protect your hands.
Place your vinegar-coated cotton balls on the floor anywhere you are concerned about mice. Note that placing them near open doors and windows will limit their effectiveness because the smell will dissipate quickly. Conversely, if you suspect you have a rats nest somewhere in your home, placing the cotton balls in enclosed spaces will enhance their effectiveness. The balls will dry out after several hours, so you will need to apply a new vinegar coating now and then.
