Can Predators Chew Through Hardware Cloth?
Most predators cannot chew through welded, galvanized hardware cloth in a practical way, but some can tear it, pull it loose at the edges or break weak welds. The mesh holds up best when it has 0.5 in openings, a solid gauge and strong fastening. The wire is rarely the weak point. The seams, corners and fasteners usually are.

A raccoon, rat or squirrel has teeth that can wear down soft materials like wood, plastic and thin hex-style poultry netting. Welded steel wire is a different story. Chewing it is slow, hard on the animal and seldom worth the effort when an easier way in exists.
What predators do instead is test the structure. They pull at corners, push on loose staples, reach through large openings and tear at thin or rusted wire. A raccoon has dexterous hands, and a dog can tug a weak panel free. So the real question is less about teeth and more about whether your mesh and your installation hold up under pushing and pulling.
Think of hardware cloth as one part of a system. The mesh stops what it can stop, and the frame, fasteners and buried edge stop the rest.
Which predators go after wire, and how
Different animals attack wire in different ways. Knowing the method helps you decide where to spend effort.
Rats and mice can gnaw at edges and squeeze through gaps. Weasels and snakes can pass through surprisingly small holes. Raccoons reach, grab and pull. Foxes, dogs and coyotes dig and tug. Hawks and owls usually go for open tops and reach through large openings.
- Rats, mice and squirrels: gnaw at edges, soft materials and any gap they find.
- Weasels and snakes: slip through openings that look too small to matter.
- Raccoons: reach through holes and pull at mesh with their hands.
- Dogs, foxes and coyotes: dig under walls and tug on loose panels.
- Birds of prey: attack uncovered runs and reach through wide openings.
Why mesh size matters more than you think
Opening size is your first defense. Our best hardware cloth for chicken coop page points to 0.5 in mesh as the size that blocks rats and weasels, and every roll on that page lists a 0.5 in opening. Poultry netting has much larger openings, so snakes and small predators can slip through, and a raccoon can reach in and grab a bird.
Smaller openings also deny teeth and claws a place to start. A predator cannot get a grip on wire it cannot get its head or paws through. That is why vents, windows and low walls, where small animals try first, deserve 0.5 in mesh.
Gauge, welds and coating: what resists damage
Wire gauge runs backward. A lower number means thicker wire, and thicker wire resists bending, tearing and gnawing better. Four of the five rolls with a gauge listed on our comparison page use 19 ga. HANWRAPS does not list a gauge, so you cannot judge how well that roll resists bending or chewing from the published specifications.
Welded construction matters too. Welded joints hold the grid rigid so a predator cannot easily spread the wires apart. Galvanizing after welding puts zinc on the joints as well, and rust tends to start at joints and cut ends. Rusted wire gets brittle and weak, which makes it easier to tear. All of the rolls listed below are hot-dip galvanized after welding.
| Option | Mesh opening | What it handles | Weak spots |
|---|---|---|---|
| Poultry netting | Large openings | Keeps chickens in, blocks little else | Snakes and small predators slip through, raccoons reach in |
| 0.5 in hardware cloth, 19 ga, welded | 0.5 in | Rats, weasels, snakes, most chewing | Can be torn at edges or pulled off loose fasteners |
| Heavier gauge mesh over hardware cloth | Varies | Added tear and pull resistance | More effort to cut and install |
Roll options from our comparison page
If you want the full side-by-side, see our hardware cloth comparison. Here are four rolls with their published specs. All use 0.5 in mesh, welded construction and hot-dip galvanizing after welding.
Roll size matters for security. A short roll means extra seams, and every seam is a place a predator can test. Buy enough to cover walls, roof and a buried apron without piecing together small offcuts.

How to install it so predators cannot get in
Most break-ins happen where the mesh meets something else. A strong install matters as much as the mesh you buy.
Follow these steps for the best result:
- Fasten the mesh to the frame with screws and large washers, not just staples. Staples pull out under steady tugging.
- Overlap seams by several inches and fasten both layers along the overlap.
- Cover every vent, window and gap, including the spots under the eaves.
- Bury an apron of mesh about a foot or more outward from the base of the run, or lay it flat and cover it, so diggers hit wire instead of open dirt.
- Use mesh on the roof too, since climbers and birds of prey use open tops.
- Check the wire, fasteners and corners regularly and patch any damage right away.
Safety notes while you build
Cut hardware cloth leaves sharp wire ends. Wear heavy gloves and safety glasses when you cut, bend or staple it, because snipped ends can fly off. Use hearing protection if you run power tools such as a screw gun for long stretches.
Work from a stable ladder when you cover a roof or high vents, and have a helper hold the roll. Wire under tension can spring back and scratch you. If you dig a trench for the apron, call your local utility locating service first so you do not hit buried lines.
Frequently asked questions
Can a raccoon open hardware cloth?
A raccoon is more likely to pull or reach than chew. Loose fasteners, thin or rusted wire and unprotected edges give it a way in, so fasten the mesh firmly and use sturdy wire.
Is chicken wire safe enough against predators?
No. Chicken wire is thin with large openings, so it keeps chickens in but does little against rats, weasels, snakes or raccoons. Use 0.5 in hardware cloth instead.
Do I need to bury hardware cloth?
Yes, for runs on open ground. Burying or laying down an apron stops animals that dig at the base, which is a common way in.
Does rust make hardware cloth easier to break?
Yes. Rust weakens wire and joints over time. Choosing mesh that is galvanized after welding helps protect the welds, where rust often starts.
