Irish Spring soap is a brand of soap that is primarily marketed in the United States. It was first introduced to the market in 1882.
The most successful advertising advertisement for Irish Spring says that it is the “best for tough jobs” and it has a “long lasting tough-as-nails formula.” The ad also says, “You know what they say about Irish Springs: they don't stop, they don't quit and they never give up."
In recent years, many people have noticed that rabbits seem to have a strong aversion to Irish Spring soap. They will run away when given a chance and if you put any pieces of soap in their vicinity, they will drop whatever they are eating and run away as fast as possible.
The oils used in the soap disrupt the rabbits’ sense of smell and this makes them change their behavior towards other foods that might be near the soap.
In conclusion, Irish Spring soap is an effective way of deterring rabbits from entering your garden without harming them or your plants.
