How to do it:
Seal all entry points with steel wool and caulk. Store goods in sealed plastic containers. Keep areas clean and free of food debris. Set up snap traps along walls. Use peppermint oil-soaked cotton balls near storage areas.

Result:
These steps can deter Norway rats from entering and damaging your goods by removing access, food sources, and using repellents.

Problem:
This method may fail if entry points are missed, traps are not maintained, or rats adapt to repellents.

How to do it:
Seal entry points with steel wool and caulk. Place peppermint oil-soaked cotton balls near goods. Use vinegar spray on surfaces. Keep area clean and food sealed.

Result:
Rats are deterred by strong scents and blocked access, reducing damage to goods.

Problem:
Persistent 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 larger than 1/4 inch with steel wool, metal flashing, or concrete.
Install door sweeps and weather stripping on doors and windows.
Store goods in rodent-proof containers.
Remove clutter and debris near storage areas.
Trim vegetation away from buildings.

Result:
Reduces rat access and protects goods from gnawing and contamination.

Problem:
Method may fail if all entry points are not found or if materials used are not durable enough to withstand gnawing.

How to do it:
Use natural predators or deterrents to keep Norway rats away from your home.

• Encourage barn owls by installing owl nesting boxes nearby.
• Adopt a cat known for hunting rodents.
• Place used cat litter or predator urine near entry points.
• Keep your yard clean to reduce rat hiding spots.

Result:
Rats are less likely to enter your house due to predator presence and scent deterrents.

Problem:
This method may fail if predators are not present, rats adapt to deterrents, or if food sources remain accessible.

How to do it:
Mix equal parts of plaster of Paris and cornmeal. Place small amounts in shallow containers near rat activity. Provide a separate container of water nearby, as the mixture will harden in the rat’s stomach after drinking.

Result:
Rats ingest the bait, leading to dehydration and death, reducing their population and protecting your goods.

Problem:
This method may fail if rats find alternative food sources, avoid the bait, or if pets and children access the mixture.
