How Mice Get Into Watford Properties (And How to Stop Them)

Mice are clever and persistent pests. They can squeeze through gaps as small as 6mm, which makes most Watford homes and businesses vulnerable. At Watford Pest Exterminators, we provide professional mice extermination in Watford starting from £260, helping customers remove infestations and block re-entry points. Here’s how mice get in — and how to keep them out.

Common Entry Points for Mice

• Gaps under doors: Mice can squeeze under poorly sealed external doors.
• Pipes and vents: Spaces around water pipes, heating systems, and air vents provide easy access.
• Cracks in walls: Small holes in brickwork or plaster can be exploited by mice.
• Garages and sheds: Unsealed garages and outbuildings often lead directly into the property.
• Lofts and roof spaces: Mice climb walls, guttering, and trees to gain access to lofts through broken tiles or gaps.
• Basements and floor voids: Dark, hidden spaces are ideal for nesting and entry.

How to Stop Mice Entering Your Property

• Seal gaps: Use steel wool or metal mesh to block small holes around doors, windows, and pipes.
• Repair roofs: Fix broken tiles, fascia boards, and vents to block access to lofts.
• Secure bins: Keep outdoor bins sealed with tight-fitting lids.
• Fit door seals: Install bristle strips or weatherproof seals under doors.
• Protect vents: Cover with fine mesh to stop mice squeezing through.

Why Professional Proofing Works Best

DIY sealing can help, but unless all entry points are identified, mice may still find a way in. Our technicians carry out full inspections, find hidden entry points, and provide long-term proofing advice to ensure infestations don’t return.
