How to Stop Squirrels from Chewing Outdoor Lights

Are pesky squirrels wreaking havoc on your outdoor lights? If you’re tired of finding chewed-up wires and missing light bulbs, you’re not alone. Many homeowners face the challenge of squirrel-proofing their outdoor lighting. But fear not! In this guide, we’ll explore effective strategies to protect your outdoor lights from these furry intruders. From understanding how to stop squirrels from chewing outdoor lights, we’ve got you covered.

Why do squirrels chew outdoor lights in the first place? These curious critters are drawn to the warmth and electrical wiring of outdoor fixtures. For them, it’s not just a matter of mischief; it’s about satisfying their natural instincts. Unfortunately, this behavior can result in damaged lights and potential safety hazards. So, how do we thwart their destructive tendencies and safeguard our outdoor illumination?

Strategies for Squirrel-Proofing

Choose Squirrel-Resistant Fixtures

Invest in outdoor lights specifically designed to withstand squirrel interference. Look for fixtures with sturdy casings and protective shields to deter chewing.

Apply a Squirrel Repellent

Utilize natural or commercial squirrel repellents to create a deterrent barrier around your outdoor lights. These repellents emit odors or tastes that squirrels find unpleasant, discouraging them from gnawing on your fixtures.

Install Physical Barriers

Consider installing wire mesh or hardware cloth around your outdoor lights to physically prevent squirrels from accessing them. Ensure the barriers are securely attached and cover all vulnerable areas.

Trim Nearby Tree Branches

Squirrels often use tree branches as launch pads to access outdoor lights. By trimming back overhanging branches, you can limit their access routes and make it more challenging for them to reach your fixtures.

Protecting Your Outdoor Wires

In addition to chewing on lights, squirrels may also target outdoor wires, posing a risk of electrical damage and fire hazards. To safeguard your wiring:

Encase Wires in Protective Conduit

Cover exposed wires with PVC conduit or metal tubing to shield them from squirrel attacks. This extra layer of protection adds a physical barrier against chewing and ensures the integrity of your electrical system.

Elevate Wires off the Ground

Whenever possible, elevate outdoor wires above ground level to reduce the likelihood of squirrel interference. Use mounting brackets or wire clips to secure them to walls, fences, or other elevated surfaces.

Pepper Spray

Pepper spray is a potent deterrent commonly used to discourage unwanted animal activity around outdoor fixtures. When applied strategically, pepper spray emits a pungent odor and taste that repels squirrels and other pests. It serves as a non-lethal but effective means of protecting your outdoor lights from chewing damage. To use pepper spray effectively, apply it to areas where squirrels are prone to chew, such as light fixtures and nearby surfaces. Reapply as needed, especially after rainfall, to maintain its potency and effectiveness.

Animal Control

Professional animal control services offer specialized expertise in managing wildlife-related issues, including squirrel infestations. By enlisting the help of trained professionals, homeowners can implement comprehensive strategies to deter squirrels and protect outdoor lights. Animal control experts may employ techniques such as trapping, relocation, and exclusion to manage squirrel populations effectively.

Additionally, they can provide valuable advice on preventive measures and long-term solutions to minimize the risk of future squirrel damage. Collaborating with animal control professionals ensures a humane and sustainable approach to addressing squirrel-related concerns.

Repairing Lights

When outdoor lights sustain damage from squirrel chewing, prompt repair is essential to restore functionality and safety. Begin by assessing the extent of the damage, examining wires, bulbs, and fixtures for signs of chewing or disrepair. Replace any damaged components, such as chewed wires or broken bulbs, with new ones to ensure proper functioning.

Use electrical tape or wire connectors to secure and insulate repaired wires, reducing the risk of electrical hazards. Additionally, consider reinforcing vulnerable areas with protective coverings or deterrents to prevent future damage. Regular maintenance and timely repairs are crucial for preserving the longevity of your outdoor lighting system.


By implementing these proactive measures, you can effectively deter squirrels from chewing on your outdoor lights and protect your property from potential damage. Remember to combine multiple strategies for maximum effectiveness, and regularly inspect your fixtures for signs of squirrel activity. With persistence and the right precautions, you can enjoy beautifully illuminated outdoor spaces without the nuisance of squirrel-induced mischief.
