Rats can gain access to homes through cracks in the foundation, the sewage system, ventilation openings, doors, windows, the roof, floor drains, and garbage containers. To prevent this, these areas should be sealed with steel mesh, rat barriers, or sealants. Regular inspection and maintenance are key to creating a home that is less susceptible to rat intrusion.

Using Steel Mesh Against Rats

Steel mesh can be effectively used to secure areas against rats due to its durability and resistance. Here are several ways in which steel mesh can be employed to prevent rats from accessing various places such as homes, properties, and gardens:

1. Coverage of openings:
- Cover openings and cracks in buildings or structures with steel mesh to prevent rats from entering. Ensure that the mesh is securely fastened to prevent rats from gnawing or forcing their way through.

2. Sewage systems:
- Install steel mesh in sewage systems or drains to prevent rats from moving into buildings through these routes.

3. Garden protection:
- Use steel mesh to create protective barriers around gardens and crops. This prevents rats from entering and disturbing the crops.

4. Under floors and ceilings:
- If there are voids under floors or between the ceiling and roof, steel mesh can be used to cover these areas and prevent rats from moving freely.

5. Garbage containers:
- Mount steel mesh around garbage containers to prevent rats from entering and spreading waste.

6. Ventilation openings:
- Cover ventilation openings with steel mesh to prevent rats from entering buildings through these openings.

7. Maintenance:
- After installing steel mesh, it is important to regularly perform maintenance to ensure that there are no holes or damaged areas where rats can get through.

It is important to mention that the best defense against rats is a combination of preventive measures and regular maintenance. A thorough inspection of buildings and surrounding areas can help identify and address any issues early on.
