The answer to 'how to prevent rodent' is to take a comprehensive approach to rodent-proofing your home. This involves sealing up entry points, removing food sources, and using deterrents to keep rodents away. Start by inspecting the exterior of your home and sealing any cracks, holes, or gaps larger than 1/4 inch where rodents could enter. Use caulk, steel wool, or other durable materials to close these openings. Next, eliminate potential food sources by storing food in airtight containers, cleaning up spills and crumbs, and keeping trash in sealed bins. You can also use natural rodent deterrents like peppermint oil, cayenne pepper, or ammonia-soaked cotton balls in problem areas.
If you continue to have issues with rodents, you may need to consider more aggressive measures like traps or professional pest control services. It's important to act quickly, as rodent infestations can quickly spiral out of control and cause significant damage to your home.
