Revisiting Irish Spring Soap to Repel Mice

It’s been over 3 years since I first posted about using Irish Spring soap to repel mice and other rodents. You can read my original post here and all the many comments concerning the pros and cons of this method.

A few things to mention and clarify are that you must use the original Irish Spring soap. Do not use the Aloe Vera scented soap as it doesn’t work and may actually attract critters with the added scent. Do not leave the soap in the box as this is also an added attraction to rodents as they love to chew on the cardboard.

Just use a small piece of soap about 1 inch square or trying grating it with a cheese grater and leave the shavings spread out to deter the rodents. Also make sure you use fresh soap and change it out to keep the odor fresh.

Also remember some people have had success with using original Irish Spring soap to ward off mice while others have not. But give it a try and see if this useful idea works for you and please share your results with us all.

Irish Spring Soap to Repel Rodents

As we live in the woods, we have many rodents such as mice and rats in the area. Recently we have had rats in the engine compartment of our vehicles. They have been leaving droppings and pulling the insulation from the hood of our pickup. They use the insulation and other materials to build nests inside the engine area. We needed to find a good solution to repel these rodents and drive them away from our vehicles.

Irish Spring Soap Piece


I took a bar of Irish Spring soap and cut off a small piece about 1 inch long. I then cut that piece in half ending with a piece of soap about 1 inch square as shown. I placed a piece of soap inside the engine compartment on the battery tray as this was one of the places we have been seeing droppings. I repeated this process for all our vehicles. Then I waited and watched.

Apparently the strong soap smell from the Irish Spring soap repels the rodents. Since I have placed the soap pieces inside the vehicle engine area, we have not had any signs that the rats have been back.

This idea may also work well for other areas where you do not want mice or rats such as your house, sheds, or garages. Give it a try and let me know how this rodent repellent works for you.

**Follow-up comment – I am hearing from several of you that this doesn’t work. I am adding a warning to others to beware that this may not work on mice. Please read the comments to see the outcomes of others.
