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.
