Why do do mice and rats come indoors in winter? As temperatures drop across Sydney, your home becomes more than just a cosy retreat for you, but it's an open invitation for unwanted guests like mice and rats. Rodents are resourceful, and even the tiniest gap or crack can be an entryway to a warm winter hideout. Your roof cavity, garage, or pantry could be their next stop if left unchecked.

During winter, food sources dry up outdoors, and rodents seek shelter near humans. With mice capable of squeezing through holes the size of a 10-cent coin, prevention is key.

Signs of Rodent Infestations

Wondering if you’ve got rodent roommates? Here are the common warning signs:

  • Droppings in pantries, under sinks, or along baseboards
  • Scuttling or scratching noises in walls or ceilings usually they hunt at night..
  • Chewed packaging, furniture, or wires
  • Nests made from shredded paper or insulation
  • Pets behaving oddly, sniffing around unusual places

If any of these sound familiar, it's time to take action before the infestation grows.

Top Prevention Tips for Mice and Rat Infestations

Keeping rodents out doesn’t have to be complicated it just takes a bit of planning and consistency.

1. Seal Entry Points

They cannot enter r house if possible entry points are closed. Start by inspecting your home’s exterior and interior. Use steel wool, wire mesh, or sealant to close off gaps near pipes, doors, roof tiles, and vents. Avoid foam sealant alone, rodents can chew through it.

2. Use Natural Rat Deterrents

Certain smells repel rodents from entering your house. You can use  natural ways to keep rodents think twice before sneaking in.

Peppermint oil: Just add a few drops to cotton balls and tuck them near potential entry points for a fresh-smelling barrier.

Apple cider vinegar spray: You can also mix up a and spritz it along baseboards where rats might travel.

Use kitty litter: Rodents tend to avoid areas that smell like a predator's territory.

These natural deterrents are great as a first line of defense, but they work best when paired with more permanent solutions like sealing gaps and keeping food securely stored.

3. Maintain Your Backyard

Keep your place clean! Rodents often start outdoors before coming inside. Start by trimming overgrown plants and tree branches near the house, elevate firewood and compost bins, and don’t leave pet food outside overnight.

4. Manage Waste Properly

Secure your bins with locking lids and clean them often. Rubbish left too close to your home is an open invitation for pests.

5. Remove Clutter Inside and Outside

Don’t let these rodents sneak o your house. Prevention is key to keep them away. Cardboard boxes, storage containers, and junk piles are perfect nesting spots. Keep your garage, attic, and shed tidy, and store items in sealed plastic bins.

6. Use Rat Baits, Traps and Poison with Caution

Snap traps and bait stations can be effective, but safety comes first especially if you have pets or children. For serious infestations, it’s best to let a pests control exterminator in Sydney handle it with safe and tamper-proof methods to keep them from from lurking in your home.
