When the temperatures drop in New Zealand, pests don’t disappear—they simply change tactics. Many species seek warmth and shelter, making your home the perfect winter retreat. While summer and autumn may bring more visible activity, winter is when preventative action pays off.

Here’s your go-to winter pest control checklist to help protect your home during the colder months.

🐭 Common Winter Pests in NZ

In winter, pests are drawn indoors in search of warmth and food. The most common cold-weather culprits include:

• Rodents (mice and rats) – Seeking warm places to nest, often in ceilings, wall cavities, and garages.
• Cockroaches – German cockroaches in particular can thrive indoors during winter.
• Cluster flies – Often found hibernating in wall voids and roof spaces.
• Spiders – House spiders may appear more frequently as they move indoors.
• Ants – Some colonies stay active and forage inside where it’s warmer.

✅ Winter Pest Prevention Checklist

🔍 Seal Up Entry Points

• Inspect around doors, windows, and vents for gaps.
• Seal holes around utility lines and pipes using steel wool or caulking.
• Fit weather stripping on exterior doors.

🧹 Declutter and Deep Clean

• Vacuum corners, behind furniture, and pantries regularly.
• Store food in airtight containers.
• Dispose of rubbish often and keep bins tightly sealed.

🚫 Eliminate Moisture

• Fix leaky taps and pipes—pests are drawn to damp areas.
• Use a dehumidifier in basements or poorly ventilated rooms.
• Clear gutters and ensure downpipes are draining correctly.

🏡 Check Roof and Attic Spaces

• Look for signs of rodent droppings or nests in roof cavities.
• Install a light in the attic—cluster flies are attracted to light and will eventually die from exhaustion.
• Ensure insulation and ceiling access points are secure.

🌳 Trim Back Vegetation

• Cut back tree branches and shrubs touching the house—these are highways for rodents and insects.
• Remove stacked wood or debris near your home’s foundations.

👀 Monitor for Signs

• Listen for scratching sounds in walls or ceilings.
• Look for droppings, grease marks, or chew damage.
