In my ongoing quest to write about topics that will be helpful to all of you, I discovered that “mouse repellent” is one of the most popular keyword searches when it comes to pest control. People are always looking for the quickest, simplest solution to these kinds of problems, so I suppose this makes sense. Since inquiring minds want to know, let’s talk about mouse repellent. Is it a thing? There are a few products on the market, both oral and aural, that claim to repel mice, but are they really effective? In this post, I’m going to talk about which methods will and won’t work when it comes to deterring mice.
Sonic deterrents are small devices that you can plug into an electrical outlet. They emit sonic or ultrasonic waves, creating a high-pitched frequency that allegedly drives mice away. Some brands even purport to work on insects. Sounds pretty great, but is an obnoxious noise really enough to cause mice to flee? In our professional opinion? No. In the opinion of the Illinois Department of Public Health? Also no. Here’s the thing: mice are really good at adapting to their surroundings. That’s why they can be found in nearly every country and climate. Yes, mice will most likely be alarmed by the sound at first, but they get used to it very quickly. Also, if you’re the kind of person who has a house with things like furniture or walls, both will obstruct sonic and ultrasonic waves, so the sound will only travel as far as the nearest sofa. Sonic deterrents are a nice idea, but definitely too good to be true.
Peppermint oil and pepper spray are common folk remedies, but they’re largely ineffective. There is a repellent called Ropel that is designed to deter animals from chewing in certain areas, and it definitely works. However, it isn’t practical to coat the whole outside of your house with Ropel, and you can’t spray it inside of your walls and ceiling, which is where mice will be doing the majority of their gnawing. Also, Ropel wears off and washes away. It really works best when used to keep squirrels or pets from chewing in an isolated area.
Making sure your house is well-kept both inside and outside can help keep mice away. They’re attracted to places they can hide and places they can eat, so removing those things is a good first step. In your yard, keep your grass and other landscaping trimmed. Don’t leave food or garbage outside. If you have a birdfeeders, keep the ground around them free of seeds. Inside, keep clutter to a minimum. Wipe up any food that has spilled on the floor. Keep pantry items like cereal or grains sealed in plastic containers.
Honestly, the most effective mouse repellent is exclusion. If you can keep the mice from getting into your home in the first place, you won’t need to worry about sonic deterrents or peppermint oil or Ropel.
