Introduction
Running low-voltage wiring such as speaker wires or landscape lighting cables in your backyard can be a great way to enhance your outdoor space. However, one common problem many homeowners face is rats and other rodents chewing through and damaging the wiring. This can create safety hazards, damage equipment, and require expensive repairs. The good news is there are several effective strategies you can use to deter rats and protect your low-voltage wires when running them through your backyard.
Choose Appropriate Wire Casing
The first step is selecting the right casing or covering for your low-voltage wiring. Bare wire cables are extremely vulnerable to rat damage. Instead, choose wires that are encased in a thick plastic or metal casing that makes it difficult for rats to chew through.
Some good options include:
-
PVC conduit - Plastic PVC tubing is affordable, durable, and resistant to rodent damage. Run your cables through PVC conduit for maximum protection.
-
Steel armored cable - For high-risk areas, steel armored cables that have an outer metal mesh shielding offer the highest level of protection.
-
Direct burial cable - Cables rated for direct underground burial have a tough polyethylene jacket that deters chewing.
Using the most damage-resistant casing available provides a physical barrier to prevent easy access to the wires themselves.
Avoid Rodent Attractants
Rats are drawn to certain smells and residues that get left on wire casings. Avoid using any lubricating gels or pulling compounds when running your wires, as these can attract rodent chewing. Thoroughly clean and wipe down the outer cable casing after installation to remove any attractive residues.
Use Avoidance Deterrents
There are several types of deterrents you can apply to your wiring and cables that will cause rats to avoid chewing on them. Effective options include:
-
Bittering agents - Apply bitter-tasting gel repellents on the wires. Rats will avoid chewing on treated surfaces.
-
Hot sauce - Coat cables with hot pepper sauce for an unpleasant taste. Reapply monthly.
-
Moth balls or flakes - The strong odor repels rats. Place moth balls or naphthalene flakes in underground wire burrows.
-
Electromagnetic devices - Battery-operated repellers produce ultrasonic waves or electromagnetic fields that drive away burrowing rodents.
The key is using deterrents that create an unpleasant environment around wires so rats avoid the area altogether. Reapply repellents regularly for best results.
Select a Protected Route
When running wiring across your backyard, select a route that avoids potential rat nesting sites. Avoid directly crossing over:
- Wood or debris piles
- Overgrown vegetation
- Burrows
- Garden mulch
Burying wires at least 12 inches underground can help reduce accessibility. Running them through protective casings like garden hose also limits exposed access. Choose the most protected path possible.
Inspect and Maintain Wires
Regularly inspect your low-voltage wiring for any signs of chewing or damage from rats. Seal up any access points with caulk or concrete if they've started to gnaw through protective casings. Check that deterrents haven't worn off and reapply as needed. Taking proactive measures to maintain and monitor your wiring helps prevent major rat damage.
By selecting durable wire casings, using avoidance deterrents, routing wires away from rodent hideouts, and performing regular inspections, you can effectively rat-proof the low-voltage wiring in your backyard. Taking the time to properly install and protect cables will prevent countless headaches caused by rats chewing through and ruining wires that aren't adequately guarded. With the right prevention approach, you can outsmart the rats and keep your wiring intact.
