Natural repellents for mice include peppermint oil, hot sauce and ammonia. These fragrant products help to keep the home free of rodents without the dangers of poisons.
Homeowners with a mouse problem sometimes find pouring ammonia around the foundation of the house helps to eliminate mice. The mouse cannot determine if the ammonia comes from a bottle or if it is left by larger predators, such as cats, since urine breaks down to form ammonia.
Tabasco sauce is another strong repellent for mice. Mixing a few drops of this hot pepper sauce, dish detergent and water in a spray bottle and spraying the area where mice are hiding can cause them to leave.
