How to do it:
Seal all entry points with steel wool or metal mesh. Store food in airtight containers. Keep storage areas clean and clutter-free. Use peppermint oil-soaked cotton balls near suspected entry points. Set up snap traps in areas where droppings are found.

Result:
These steps can deter Black Rats from entering and damaging your goods by removing food sources and blocking access.

Problem:
If entry points are missed or food is left exposed, rats may still find a way in. Persistent infestations may require professional pest control.

How to do it:
Seal entry points with steel wool and caulk. Place peppermint oil-soaked cotton balls or sachets near goods. Use bay leaves or cloves in storage areas. Keep spaces clean and free of food crumbs.

Result:
Rats are repelled by strong scents and blocked from entering, reducing damage to goods.

Problem:
Rats may adapt to scents or find new entry points, making this method less effective over time.

How to do it:
Seal all entry points (cracks, holes, vents) with steel wool or metal mesh. Install door sweeps and weather stripping. Store goods in rodent-proof containers. Regularly inspect and maintain barriers.

Result:
Reduces black rat access to goods, minimizing damage and contamination.

Problem:
Method may fail if all entry points are not found or if barriers degrade over time, allowing rats to re-enter.

How to do it:
Use natural predators like barn owls to control black rats. Install owl nesting boxes near your home to attract owls. Keep your yard clean to encourage owl visits. Avoid using rodenticides that could harm owls.

Result:
Owls may reduce black rat populations, decreasing the chance of rats entering your house and damaging goods.

Problem:
This method may fail if owls do not settle in the area, or if there is insufficient food or shelter for them.

How to do it:
Mix equal parts of plaster of Paris and flour, add a little sugar to attract rats. Place small amounts in shallow containers near rat activity. Provide a separate dish of water nearby, as the mixture hardens in the rat’s stomach after drinking.

Result:
Rats ingest the mixture, which hardens internally, leading to their death and reducing damage to goods.

Problem:
Rats may avoid the bait if they detect the chemical smell, or pets and children may accidentally consume it, making this method risky and sometimes ineffective.
