Why Rat-Proofing Is Essential

1. Prevent Infestations

  • Blocking entry points stops rats from accessing your home.

2. Protect Your Property

  • Avoid damage to wiring, insulation, and stored items.
  • Safeguard your family’s health from diseases spread by rats.

3. Save Money and Time

  • Proactive measures are more affordable than dealing with infestations and repairs.

    • Flashlight, mirror, and gloves.
  • What to Look For:
    • Holes, cracks, or gaps larger than ½ inch.
    • Signs of rat activity, such as droppings, gnaw marks, or grease trails.
  • Common Problem Areas:
    • Around pipes, vents, windows, and doors.
    • Attics, basements, and crawl spaces.

2. Seal Entry Points

  • Materials to Use:
    • Steel wool for small holes.
    • Caulk, expanding foam, or cement for cracks.
    • Metal mesh or grates for vents and drains.
  • Steps:
    1. Clean and dry the area.
    2. Fill gaps with steel wool or mesh.
    3. Secure the material with caulk or foam for a durable seal.

3. Secure Doors and Windows

4. Eliminate Food and Water Sources

    • Use rat-proof trash bins with tight-fitting lids.
    • Keep compost piles covered or in sealed containers.
