10 effective rodent repellent solutions to keep mice out of your home and RV

Mice may look cute, but these furry rodents carry disease and cause destruction when they appear in your home or RV. Now is the time to mouse-proof where you live.

There are many options for repelling mice. Older lethal methods of traps and poison remain available, but a push toward more humane, organic deterrents has led to a surge in alternative strategies. Consider which ones are best for your home or RV, and act now. 

In this article: Natural Armor Mice and Rat Repellent, Dr. Catch Humane Mouse Traps and Xcluder Rodent Barrier Kit.

First, inspect your home or RV 

Mice can only get in your home or RV if there are gaps in the structure or near where pipes and ductwork enter. Look for small cracks and holes, and use sealant caulk to fill the space permanently. Steel wool also can be pushed into the gap since mice don't like trying to gnaw through it. 

Another easy solution is to remove all available food sources. Walk through your kitchen and note any food sitting out, especially if it is not in a sealed container. Unsealed food is a mouse's smorgasbord. Makes sure all food on counters or in cupboards is stored in airtight food storage containers. Stainless steel containers are best since mice cannot chew through them. 

Organic and humane repellent strategies

Consider these four methods:

  • Peppermint oil and cinnamon are natural scents that repel mice. They come in sprays and pouches that can keep mice away while making your home or RV smell good.
  • Hot pepper sprays also work, but they have a more pungent scent you may not want wafting through your living space. 
  • Humane live traps capture mice in small boxes when the bait is taken and a spring-loaded back door snaps shut. The trap can then be taken far away where mice can be released. 
  • Ultrasonic monitors send variable frequencies through the air that greatly bother mice to the point that they will leave rather than conduct their business in such chaos. 

The tried and true methods still work

For some people, the methods used by past generations are sufficient. Snap traps, glue traps and poison bait stations are lethal for the mouse. The entire trap and mouse carcass are then disposed. Keep in mind that killing mice has not been proven to lower the mouse population, as new ones typically move in for available food sources.

Options you can't buy online

Saturday-morning cartoons were more factual than you may realize. Cats and mice are mortal enemies. Owning a cat can keep mice away. Mice know cats can smell them, and cats emit chemicals that terrify mice. Obviously, your feline friend can't be purchased on Amazon or other online retailers. Check your local humane shelter or reputable breeders in your area. 

If your mouse problem won't respond to any of these options, you may need to contact a professional exterminator. This is more expensive, but the results are usually guaranteed.
