Can Squirrels Bite Through Chicken Wire? Separating Fact from Fiction
Yes, under the right circumstances, squirrels can and sometimes do bite through chicken wire. However, it’s not always a squirrel’s first choice, and the quality and condition of the chicken wire significantly impact its vulnerability.
Understanding the Squirrel’s Gnawing Drive
Squirrels are rodents, and like all rodents, their incisors continuously grow. To keep these teeth from becoming overgrown, they constantly gnaw. This isn’t always about finding food; it’s often a biological imperative. The harder the material, the more effective it is at grinding down their teeth. This inherent need makes them particularly troublesome for homeowners seeking to protect gardens or structures.
The Weakness of Chicken Wire
Chicken wire, or hexagonal wire mesh, is constructed from thin, low-gauge wire. While it’s relatively inexpensive and easy to work with, its construction inherently makes it vulnerable to determined gnawing.
- The thin wire is relatively easy for squirrels to grip and bite through.
- The hexagonal pattern can create weak points, especially at the junctions where the wires are twisted together.
- Galvanized chicken wire offers some rust protection, but the coating provides minimal resistance to chewing.
Factors Influencing Squirrel Chewing
Several factors influence whether a squirrel will target chicken wire:
- Hunger and desperation: A hungry squirrel is far more likely to attempt to breach a barrier, regardless of its strength.
- Accessibility of food sources: If a tempting food source, like birdseed or garden vegetables, lies just beyond the chicken wire, the motivation to chew increases dramatically.
- Alternative food sources: Abundant natural food sources can reduce a squirrel’s need to chew on structures.
- The condition of the chicken wire: Old, rusted, or damaged chicken wire is significantly weaker and easier to penetrate.
- The availability of alternative chewing materials: If squirrels have access to softer materials like tree bark or branches, they may be less inclined to target chicken wire.
- Population density: High squirrel populations can increase competition for resources, leading to more aggressive behavior and a higher likelihood of chewing.
Alternatives to Chicken Wire
While chicken wire has its uses, it’s generally not the best choice for squirrel-proofing. Consider these alternatives:
- Hardware cloth: This is a more robust woven wire mesh made from thicker gauge wire, providing significantly better resistance to chewing.
- Solid barriers: Sheet metal, wood, or plastic can offer complete protection, but may not be suitable for all applications.
- Electric fencing: A low-voltage electric fence can deter squirrels without causing harm.
- Squirrel-resistant feeders: If protecting birdseed is the goal, use feeders specifically designed to prevent squirrels from accessing the seed.
Prevention Strategies
Beyond choosing the right materials, consider these preventative measures:
- Remove food sources: Eliminate or secure bird feeders, pet food, and other potential attractants.
- Clear vegetation: Trim trees and shrubs that provide squirrels with access to structures.
- Seal entry points: Inspect your home for cracks and holes, and seal them with appropriate materials.
- Use repellents: Consider using commercially available squirrel repellents, but be aware that their effectiveness can vary.
- Trapping and relocation: This is a more controversial method and may be subject to local regulations. Consult with a professional wildlife control service.
Comparing Wire Mesh Options
| Material | Wire Gauge (Lower is Thicker) | Chew Resistance | Cost | Best Use |
|---|---|---|---|---|
| —————– | —————————— | ————— | ——— | ———————————————— |
| Chicken Wire | 20-22 | Low | Low | Light-duty fencing, temporary enclosures |
| Hardware Cloth | 16-19 | High | Medium | Squirrel-proofing, garden protection |
| Welded Wire Mesh | 14-16 | Very High | High | Heavy-duty fencing, animal enclosures |
Frequently Asked Questions (FAQs)
Can squirrels bite through chicken wire if it’s brand new?
Even new chicken wire is vulnerable to squirrels. While it’s stronger than old, rusted wire, its thin gauge still makes it possible for squirrels to chew through, especially if they’re highly motivated.
Is galvanized chicken wire more resistant to squirrel bites?
The galvanization process provides some rust protection, but it doesn’t significantly increase the wire’s resistance to chewing. Squirrels are still able to bite through galvanized chicken wire.
What is the best type of wire to use for squirrel-proofing?
Hardware cloth is generally considered the best option for squirrel-proofing. Its thicker gauge and tighter weave provide significantly better resistance to chewing than chicken wire.
Will painting chicken wire deter squirrels?
Painting chicken wire might offer a minimal level of deterrence, but it’s not a reliable solution. Squirrels are primarily motivated by hunger and access to food, so paint is unlikely to deter them for long.
How long does it typically take a squirrel to chew through chicken wire?
The time it takes a squirrel to chew through chicken wire varies depending on the squirrel’s determination, the condition of the wire, and the availability of alternative chewing materials. It could take anywhere from a few hours to a few days.
Can squirrels bite through other types of metal mesh besides chicken wire?
Yes, squirrels can potentially bite through other types of metal mesh, but the thicker the wire gauge and the tighter the weave, the more difficult it will be. Hardware cloth and welded wire mesh are much more resistant than chicken wire.
Are there any natural repellents that can deter squirrels from chewing on chicken wire?
Some people have had success with natural repellents like cayenne pepper, peppermint oil, or garlic. However, the effectiveness of these repellents can vary, and they may need to be reapplied frequently, especially after rain.
Is it more effective to use chicken wire with smaller or larger openings for squirrel-proofing?
While smaller openings are generally better, they aren’t as important as the wire gauge. Squirrels can still chew through the wire itself, regardless of the opening size. Focus on using a thicker wire, such as hardware cloth, with smaller openings.
Can baby squirrels bite through chicken wire?
Yes, even baby squirrels can bite through chicken wire, although they may be less effective than adult squirrels. Baby squirrels are still learning to gnaw and may be less persistent, but the thin wire is still vulnerable to their developing teeth.
Is it cruel to use chicken wire to try and keep squirrels out of my garden?
Using chicken wire is not inherently cruel, but it’s important to ensure that squirrels don’t become trapped or injured by it. Regularly inspect the chicken wire for damage and make sure it’s properly secured. Consider using a more robust barrier to avoid any potential harm.
Can squirrels bite through chicken wire if it’s covered in plastic?
A thin layer of plastic won’t deter a determined squirrel. In fact, the plastic might make it easier for them to grip the wire and chew through it.
What should I do if I find a squirrel has already bitten through my chicken wire?
Repair the damaged section immediately with a more robust material like hardware cloth. Identify and eliminate any attractants that may have motivated the squirrel to chew through the wire in the first place. This involves securing food sources, and ensuring no access points.
