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.

    I tried the Irish Spring Soap to repel the mice/rats, came back a few days later box was chewed open and soap was gone. They ate it.

      Nicky – Sorry to hear your results. I know some people have used this idea and it worked while others have had only marginal success. You might try the cayenne pepper tip as many people have had great results with it.

    We have field mice in the attic (they don’t bother us) but the field rats are getting in the house/walls. But when the house was built they didn’t put in the metal to keep them out; plus no basement. I doubt they left cause my dachschund keeps hearing them. Oh well worth a shot.

    I totally agree with this. I have a cabin that I have to close for the winter..I heard about this and thought thati would try it….since I have been using the soap, I have not seen a mouse at my cabin…..I also have a puppy and I don’t have to worry about it harming him…

    I use Irish Spring every year in my RV. The only time the nice chew the soap is if we accidentally get aloe instead of original. We also never leave the boxes out as mice love cardboard for nesting. It has definitely worked for us!
