If you’ve ever dealt with rats or mice in your Pacific Northwest home, you know how unnerving it can be. Rodents may be a common pest all year long, but did you know infestations spike during the fall in Portland, Seattle, and Boise? Fortunately, there are home remedies that repel rodents naturally. Here are 6 home remedies to repel rodents:


Plants like lavender, elderberry, daffodils, and any type of mint plants are known to repel mice. You could plant some around your home or keep them in pots inside your home. Bay leaves and oak leaves have also been known to deter rodents. You can leave some around your home or put some in sachets and leave them in closets and drawers. This method not only makes your home look and smell nice, but it can help deter rodents.

Ammonia and Vinegar Spray

Another natural rat and mouse repellent is ammonia. These rodents hate the smell of ammonia because it’s similar to a predator’s urine. Fill a spray bottle with 1 cup ammonia and 1 cup vinegar, then mix it. Spray it where you often see rodent activity. Alternatively, you could spray or dip cotton balls with the solution and leave it in these areas, they’ll just need to be replaced after two weeks.

Essential Oils

This method not only helps deter rodents but it also makes your home smell nice in the process. Essential oils that may be helpful in repelling rats and mice include peppermint oil, lemon oil, citronella oil, and eucalyptus oil. You can make an essential oil spray by mixing 2 teaspoons of oil with 1 cup of water or rubbing alcohol in a spray bottle. Then spray it anywhere you see traces of rodents. Like the ammonia spray, you can also use cotton balls. If you choose the spray method, you’ll want to reapply in about a week and if you use cotton balls, replace them after two weeks.

Fill in Holes and Use Barricades

If you notice cracks or holes that a mouse or rat may use to gain access into your home, fill them in with caulk. You can also fill in larger gaps with a mix of caulk and steel wool. Steel wool is a harder material to chew through for these rodents.

Rat and Mouse Traps

If you aren’t seeing success with your natural rodent repellants, you may need to resort to mouse and rat traps. There are traditional snap traps, glue traps, and the more humane option, catch-and-release traps. You’ll want to first identify which type of rodent you’re dealing as a mousetrap is too small for a rat.
