The Seasonal Surge: Why Winter in Melbourne Brings More Rats and How to Combat Them

As winter settles in Melbourne, residents often face an unwelcome visitor: rats. These rodents, seeking warmth and food, become more active during the colder months, leading to a noticeable increase in infestations. Understanding why this surge occurs and how to effectively combat it is essential for maintaining a safe and healthy home or business environment. In this blog, we’ll delve into the reasons behind the seasonal spike in rat activity and provide practical strategies for the prevention of infestations and how to get rid of rats.

Why Winter Attracts Rats

Rats, like many other animals, seek refuge from the harsh conditions of winter. The cold weather and scarcity of food sources drive them to find shelter in warmer, more stable environments—often within human dwellings. Here are the primary factors contributing to the rise in rat activity during winter:

• Seeking Warmth and Shelter: As temperatures drop, rats look for warm places to nest. Buildings, with their consistent heat sources, provide an ideal habitat. Roof voids, basements, and wall cavities become prime real estate for these rodents.
• Food Scarcity Outdoors: Natural food sources become scarce in winter, pushing rats to forage closer to human habitats where food is more readily available. Unsecured rubbish bins, pet food, and kitchen scraps offer an easy meal for hungry rodents.
• Increased Breeding: Contrary to popular belief, rats breed year-round. However, the stress of cold weather can accelerate their reproductive cycle, leading to a population surge in winter. A single pair of rats can produce dozens of offspring in a matter of months, compounding the problem.

Common Winter Entry Points for Rats

Understanding where and how rats enter buildings is crucial for effective prevention. Common entry points include:

• Gaps in Doors and Windows: Even small cracks and crevices around doors and windows can provide access. Rats can squeeze through openings as small as about 6.5 millimetres.
• Roof voids, Basements, and Crawl Spaces: These areas often have gaps, vents, or structural weaknesses that rats exploit. Poorly sealed eaves, soffits, and roof vents are particularly vulnerable.
• Overhead Powerlines and Pipes: Rats can use powerlines and plumbing pipes, as pathways into buildings. Check where these lines enter your home for potential entry points.

Preventive Measures for Winter

Prevention is the first line of defence against rat infestations. Implementing these rodent control measures can help keep your property rodent-free:

• Inspect and Seal Entry Points: Conduct a thorough inspection of your property, focusing on potential entry points. Use materials like steel wool, caulk, and metal flashing to seal gaps and cracks. Ensure doors and windows fit tightly and have no gaps.
• Proper Insulation and Ventilation: Ensure your roof void, basement, and crawl spaces are well-insulated and ventilated. This not only helps keep these areas warm and dry but also makes them less attractive to rats.
• Safe Storage of Food and Waste: Store food in airtight containers and clean up spills promptly. Secure rubbish bins and keep them away from your home. If you have pets, avoid leaving pet food out overnight.

DIY vs. Professional Rodent Control

While DIY methods can be effective for minor issues, significant infestations often require professional pest control intervention. Here are some considerations:

• DIY Methods: Setting traps, using natural repellents, and maintaining cleanliness can manage small infestations. However, DIY methods may not address the root cause or provide long-term solutions.
• Professional Pest Control: Hiring professionals like Dawson’s Australia offers several advantages. Experts can conduct thorough inspections, identify and seal entry points, and implement effective treatment plans tailored to your specific situation. They also provide ongoing monitoring and maintenance to prevent future infestations.
• Long-Term Prevention and Maintenance: Implement an integrated pest management (IPM) approach, combining sanitation, exclusion, and monitoring. Regularly inspect your property for signs of rats and maintain preventive measures year-round.
