- Drains and Pipes: Install metal grates or screens on drains and cover pipe openings to prevent entry.
Eliminate Food Sources
Rats are attracted to readily available food. Eliminating these sources is essential:
- Secure Food Storage: Store food in airtight containers, especially in kitchens and pantries. Avoid leaving pet food out overnight.
- Prompt Waste Disposal: Dispose of food waste promptly and use trash cans with tight-fitting lids.
- Outdoor Food Sources: Remove fallen fruits, nuts, and seeds from outdoor areas. Keep bird feeders away from the house.
- Pet Feeding Areas: Clean pet feeding areas regularly and avoid leaving food out, especially overnight.
Maintain Cleanliness
Maintaining cleanliness deprives Norway rats of shelter and food:
- Regular Cleaning: Clean your home regularly, paying special attention to areas where food is prepared and stored.
- Declutter: Reduce clutter in and around the home to eliminate potential nesting sites. Use sealed containers to store items in basements and attics.
- Yard Maintenance: Keep the yard tidy by trimming plants and bushes and removing debris.
- Inspect and Clean Storage Areas: Regularly inspect and clean basements, attics, and other storage areas to ensure they remain uninviting to rodents.
Consistency in these preventative measures helps keep Norway rats at bay.
