How to Stop Rats This Winter?

Winter is the season when many pests, including rodents, seek warmth and shelter inside our homes. Mice, rats, and other rodents are particularly adept at finding their way into homes in search of food, warmth, and nesting sites. These pests not only cause damage to your property but can also pose health risks through contamination and the spread of diseases. If you’re concerned about rodents invading your home this winter, here are some practical tips to stop them before they find a way inside.

What Happens to Rats in the Winter?

As the temperature drops, rats seek warmth, food, and shelter. During the colder months, rats are more likely to enter homes and buildings in search of a comfortable environment to survive. In the wild, they typically huddle together in burrows or nests to keep warm, but indoor environments, such as basements, attics, and walls, offer a much safer and cozier refuge.

Rats are excellent survivors, and they adapt to the changing seasons by altering their behaviour. They might become more active during the night, searching for food and water, or they might hide in warmer spots during the day. If food sources outside become scarce due to the cold, rats will look for any available food inside your home, making your pantry, trash, and even pet food a tempting target.

How Winter Affects Rat Behaviour?

Winter changes the behaviour of rats in several ways. When temperatures drop, rats become more desperate to find a warm environment, making your home a prime target for infestation. During the colder months, rats tend to be more persistent in their search for food, and they can be more likely to enter homes through cracks, holes, and unsealed areas.

Additionally, winter forces rats to nest in areas with higher humidity, making basements, attics, and wall cavities even more attractive. This is why it’s essential to seal gaps and keep your home clean to avoid providing them with easy access to food and shelter. Rats may also breed more in winter since it’s easier to find warmth and shelter indoors, increasing the likelihood of an infestation.

Signs of Rats in Your Home

Before taking action, it’s essential to recognise the signs of a rat infestation. Rats are often active at night, so you may not see them directly, but their presence can be detected by:

  • Droppings: Rat droppings are usually found near food sources, in hidden corners, and around cabinets or pantries.

  • Gnaw Marks: Rats tend to chew on wood, plastic, insulation, and wires. If you notice damage to these materials, it could be a sign of an infestation.

  • Noises: Scratching or scurrying sounds, especially in walls, ceilings, or attics, could indicate rodent activity.

  • Odour: A musky or urine-like smell is another common sign that rats are present.

If you notice any of these signs, it’s time to take action to prevent further damage and health risks.

How to Stop Rats This Winter

Now that you understand why rodents are more likely to invade your home during the colder months, here are some effective steps to stop them:

1. Seal Entry Points

Rats can enter through surprisingly small gaps. Mice can fit through holes the size of a dime, and rats can squeeze through openings as small as a quarter. To stop rats, start by sealing all potential entry points.

  • Check for Gaps: Inspect the foundation, windows, doors, vents, and the roof for cracks, gaps, or holes.
  • Seal with Caulk: Use caulk or expanding foam to seal cracks around windows and doors.
  • Use Steel Wool: For larger holes, fill them with steel wool before sealing with caulk. This material is impervious to rodents’ chewing efforts.

2. Keep Your Home Clean and Tidy

Rats are always on the lookout for food sources, and a messy home is an open invitation for them to invade. By keeping your home clean, you can eliminate many potential food sources that attract rodents.

  • Store Food Properly: Keep all food, including pet food, in sealed containers. Clean up crumbs, spills, and food wrappers immediately.
  • Take Out Trash Regularly: Dispose of trash, especially food scraps, regularly, and make sure bins have tight-fitting lids.
  • Declutter: Rodents love hiding in cluttered spaces. Organise basements, attics, and storage areas, and keep them free of unnecessary items.

3. Use Rat Traps

Setting up traps is an effective way to capture rats that may have already entered your home. There are several types of traps to choose from, including snap traps, live traps, and glue traps.

  • Snap Traps: These traps are quick and effective for killing rodents. Place them along walls where rodents tend to travel.
  • Live Traps: For a more humane approach, live traps capture rodents alive, allowing you to release them far from your property.
  • Baiting: Use attractive bait such as peanut butter, chocolate, or oats to lure rats into the traps.

4. Use Natural Rat Repellents

If you’re looking for a chemical-free way to deter rodents, several natural repellents can help. These options are safe for homes with children and pets.

  • Peppermint Oil: Mice and rats dislike the strong scent of peppermint. Soak cotton balls in peppermint oil and place them in areas where rodents are active.
  • Cayenne Pepper or Cloves: Sprinkle cayenne pepper or cloves in areas like entry points, corners, and hidden spaces.
  • Bay Leaves: Place dried bay leaves in cabinets, drawers, and storage areas to keep rodents away.

5. Maintain Your Yard

Rats can enter your home from the outside, so keeping your yard well-maintained is an important part of preventing infestations. Overgrown vegetation, piles of leaves, or debris can provide shelter and food sources for rodents.

  • Trim Overgrown Plants: Keep trees, shrubs, and plants trimmed, especially those that are close to your home.
  • Clear Debris: Remove leaves, woodpiles, and trash from your yard to eliminate hiding spots for rodents.
  • Keep the Grass Short: Mice and rats prefer tall grass as it offers cover. Keeping your lawn mowed will help deter them from entering.

6. Hire a Professional Rodent Control Service

If the problem persists despite your best efforts, it may be time to call in a professional rodent control service. Experts can assess your home, identify rodent entry points, and provide targeted treatment to get rid of the infestation.

  • Schedule an Inspection: Pest control specialists will conduct a thorough inspection to identify areas that need attention.
  • Ongoing Prevention: Professional services can offer regular treatments to ensure your home stays rodent-free throughout the winter months.

Conclusion

Stopping rodents this winter requires a proactive approach. By following these tips, you can significantly reduce the chances of an infestation. Sealing entry points, keeping your home clean, using traps, and applying natural repellents are all effective strategies to prevent rodents from entering your home.

They took the time to investigate the cause, the source of the problem and elimnated it completely which included going through every cupboard, cracks hiding spots the lot. We had a cochroach problem in our apartment for 3 months and we had 4 different companies come out and NONE of them investigated they only sprayed.
