The answer to 'natural rodent repellent' is to use a variety of natural deterrents and exclusion methods to keep rodents out of your home. Some effective natural repellents include peppermint oil, cayenne pepper, and castor oil. These can be applied around entry points and other areas to deter rodents. Additionally, sealing up any cracks and holes in your home's exterior with caulk or steel wool can physically prevent rodents from getting inside.
It's important to consistently apply and reapply these natural repellents, as their effectiveness may diminish over time. Regularly inspecting your home for signs of rodent activity and addressing any entry points is also crucial for long-term prevention.
