HOW TO SEAL ENTRY POINTS TO KEEP RODENTS OUT

SUMMARY
Rodents can squeeze through tiny gaps to invade your home, bringing health risks and property damage. Learn how to identify, seal, and reinforce potential entry points using simple materials and techniques to keep your space rodent-free for good.

FEATURES
• Identify Common Entry Points: Where rodents typically get inside
• Use Steel Wool and Caulk: A tough combo rodents can’t chew through
• Seal Foundation Cracks: Close off gaps in walls, floors, and the basement
• Weatherstrip Doors and Windows: Prevent rodents from slipping through gaps
• Cover Vents and Openings: Use mesh to block access without blocking airflow
• Inspect Utility Lines: Secure areas around pipes, cables, and drains

DESCRIPTION
Rodents are resourceful and can enter your home through gaps as small as a quarter-inch. Sealing entry points is one of the most effective ways to prevent mice and rats from getting inside. This guide walks you through how to detect these openings and seal them effectively.

Start by conducting a thorough inspection of both the inside and outside of your home. Look for small holes or cracks in the foundation, around doors and windows, under sinks, and where utility lines enter your house. Don’t overlook attics, basements, garages, and crawl spaces—these are common areas for rodent access.

Once you identify the gaps, the next step is choosing the right materials to seal them. Steel wool combined with caulk is a powerful solution—mice can’t chew through the steel fibers, and the caulk holds it in place. For larger holes, use metal mesh or wire screen and secure it with screws or heavy-duty staples.

Foundation cracks, especially in basements or slab floors, are common rodent gateways. Use concrete patch or expanding foam to seal those properly. Be sure to smooth and seal every surface so rodents can’t exploit weak points.

Doors and windows can also be a weak spot. Install weatherstripping along the edges and door sweeps at the bottom. Even a small gap can be an invitation for rodents. Check that windows close tightly and repair any damaged screens.

Vents and other utility openings like dryer vents, exhaust fans, and chimneys need special attention. Cover these with metal mesh to allow air to flow while keeping rodents out. And don't forget the areas around pipes, electrical conduits, and cable lines—use caulk or foam to seal gaps around them.

By staying proactive and sealing these entry points thoroughly, you significantly reduce the chance of a rodent infestation and protect your home from costly damage and health hazards.
