Keep Rodents Out and Warmth In This Winter

As soon as winter hits, rodents start searching for warmth, and your home becomes a prime target. If you’re wondering how to get rid of rats, how to get rid of mice, or simply want to keep energy bills down, the best solution is simple: seal the gaps and stop rodents before they get inside.

Below is a quick, budget-friendly guide to staying warm, saving money, and keeping pests out this winter.

Why Rodents Invade Homes in Winter

Cold weather pushes rats and mice indoors through tiny cracks around doors, brickwork, vents, and pipes. Mice only need 6mm; rats just 12-15mm. That’s smaller than a pencil! Once inside, they can chew wires, contaminate food, and create costly damage.

By sealing these gaps, you achieve a double winter win:

Keep your valuable heat inside

Keep rodents outside where they belong

🚪 Brush Strips: Block Draughts, Stop Entry

Brush strips are one of the simplest ways to proof your home. They seal gaps under doors, keeping warm air in while preventing rodents from squeezing through.

Brush Strips 180 Degree: Neat seal for straight‑edge doors.

Brush Strips 90 Degree: Perfect for right‑angled frames.

Brush Strips 45 Degree:Ideal for angled thresholds.

Not only do brush strips stop pests, they also reduce draughts, helping you save on heating bills.

🧱 Seal Cracks and Gaps

Rodents are experts at exploiting weaknesses in brickwork, vents, and pipe entries. Use Raxwool Rodent Barrierand RaxStop Rodent Sealant to block these access points. Look for products reinforced with metal fibres or designed specifically for pest control, as standard DIY fillers can be chewed through.

🪟 Air Brick Covers for Vents and Gaps

Ventilation is essential, but open air bricks are an open invitation to rodents. Preventavent Air Brick Covers are purposely designed to keep airflow intact while blocking rats and mice from squeezing through.

🐭 Why Prevention Beats Cure

Traps and baits can help once rodents are inside, but prevention is always cheaper, safer, and more effective. By proofing your home before temperatures drop, you avoid infestations, protect your property, and reduce the need for chemical treatments.

🏠 Winter Proofing Checklist

Fit brush strips to all external doors

Seal cracks in brickwork and around pipes

Install mesh screens on vents

Inspect lofts, garages, and sheds for gaps

Keep food stored securely to avoid attracting pests

Final Word

This winter, don’t let rodents steal your warmth or your peace of mind. With simple proofing solutions like brush strips, mesh, and sealants, you can keep rats out, keep mice out, and keep your energy bills down, all at the same time.
