Mastertrap Stainless Steel Mouse and Rat Proofing Mesh 100mm

Professional-grade woven stainless steel mesh designed to permanently block rats and mice from entering through gaps, holes, and structural openings. The dense woven construction is extremely difficult for rodents to chew through and creates a long-term exclusion barrier once installed.

Designed for both residential and commercial proofing work, this mesh handles a wide range of common entry points. Compress it into cavity walls where rodents are travelling between brick courses, pack it under roof tiles at the eaves, wrap it around pipe penetrations, or secure it over air bricks, vents, and irregular openings. The woven structure compresses easily to fit tight spaces, then springs back once released to expand and fill the void completely.

This spring-back action creates a tight mechanical fit that locks the material firmly in place. In many cavity applications, it holds without relying on adhesives or fasteners. For surface-mounted installations or larger openings, the mesh can be cut to size and tacked, stapled, or glued securely over the entry point.

Unlike steel wool, which deteriorates when exposed to moisture, or copper mesh that can oxidize and stain surrounding materials, this stainless steel maintains its structural integrity and appearance in all weather conditions. It won’t rust, discolour, or break down over time, making it suitable for permanent proofing work indoors or outdoors.

The 5-metre roll provides enough material to seal multiple entry points in a single purchase. It cuts easily with standard tools and can be shaped to suit each specific opening. Suitable for residential and commercial proofing. Effective against rats and mice. Available in multiple widths to suit different gap sizes and applications.

Key features:
Professional-grade woven stainless steel — creates a durable exclusion barrier that rats and mice cannot chew through
Compresses and springs back — expands to fill gaps tightly and often holds in place without adhesives in cavity applications
Versatile width for varied applications — cavity walls, roof gaps, pipe penetrations, air bricks, vents, irregular openings
Won't rust, stain, or deteriorate — maintains effectiveness indefinitely unlike steel wool or copper alternatives
5-metre roll, easy to cut — covers multiple proofing locations, adapts to exact dimensions needed on site

Made in UK from 100% recyclable stainless steel

Choosing the Right Width
Selecting the correct width depends on how the material will be installed and the size of the gap being sealed. If in doubt, choose a width slightly wider than the visible gap to allow compression and expansion for a tighter mechanical fit.

20mm — Best for narrow gaps, small cracks, and tight utility penetrations. Ideal for fine detail work and minor mouse entry points.
50mm — Suitable for small cavity gaps, service entry points, and tighter roofline openings.
100mm — A versatile mid-range width for larger gaps, air bricks, and general proofing applications.
150mm — Designed for wider openings, deep cavity fills, larger vents, and areas requiring more surface coverage.
