How to Keep Squirrels From Chewing Through Your Outdoor Christmas Lights

The holiday season is a magical time filled with beautiful lights and decorations. However, those twinkling outdoor Christmas lights can attract unwanted attention from local wildlife, especially squirrels. These bushy-tailed rodents love to chew through wires and can cause extensive damage to your decorative displays.

Don't let pesky squirrels ruin your holiday decor. There are several effective strategies you can use to deter squirrels and protect your Christmas lights from their teeth. In this detailed guide, I will provide in-depth information on how to keep squirrels from chewing through your outdoor Christmas lights.

Why Squirrels Chew on Christmas Lights

Before learning how to prevent squirrels from damaging your Christmas lights, it helps to understand why they are drawn to the wires and cables. Here are the main factors that motivate squirrels to chew:

Chewing is Instinctual

Squirrels are rodents, and like other rodents, they have a natural instinct to chew and gnaw. Their front teeth constantly grow throughout their lifespan. The act of chewing helps file down and maintain their teeth at an appropriate length.

Even if they aren't hungry or don't intend to eat something, squirrels need to chew. Unfortunately, Christmas light wires and plastic cables provide ideal chewing surfaces to satisfy this instinct.

Interest in the Materials

In addition to the need for chewing, squirrels seem attracted to the plastic coating and copper wires that make up Christmas lights.

The plastic insulation has salts from manufacturing processes that appeal to their taste buds. The outer coating also provides texture and resistance for filing down teeth.

The copper metal conducts heat in their mouths, which squirrels appear to enjoy. The warmth is inviting on cold winter days. Copper also contains nutrients like iron and magnesium that may attract them.

Seeking Entertainment

Squirrels are highly intelligent and playful animals. Chewing on Christmas lights offers mental stimulation and entertainment for bored squirrels during the winter.

The dangling lights moving in the breeze triggers their curiosity. Interacting with the wires and cables provides an outlet for their innate desire to play.

Electrical Current Sensations

Another theory is that squirrels may chew on lit Christmas lights because they enjoy the tingling electrical current passing through the wires. The mild shocks and vibrations can produce a pleasurable or exciting sensation.

Understanding these motives behind the behavior helps guide tactics to deter squirrels from chewing on lights. Next, let's explore your options to protect outdoor Christmas decor from damage.

Deterrent Methods to Stop Squirrels from Chewing Lights

There are various simple, humane ways to discourage squirrels from chewing through Christmas light wires. Using a combination of several deterrents is most effective to prevent these persistent rodents.

Apply Undesirable Substances to the Wires

You can coat wires with foul-tasting, smelly, sticky, or spicy substances to deter chewing. Popular homemade concoctions include:

• Hot sauce or capsaicin oil - Avoid touching bare skin to irritating hot pepper solutions.

• Peppermint oil - Strong herbal smell repels squirrels. Needs reapplication after rain.

• Vicks VapoRub® - Camphor and menthol smells overwhelm squirrel's sensitive nose.

• Alcohol or vinegar - Unpleasant bitter tastes.

• Petroleum jelly - Sticky texture sticks to teeth. Avoid lights with exposed wires.

• Bar soap - Apply and let dry. Soapy residue deters chewing.

Reapply these protective coatings frequently to maintain efficacy. Consider potential damage or staining effects on lights before using.

Wrap Wires in Protective Materials

You can wrap Christmas light cables in protective casings to create a physical barrier against squirrel teeth:

• Flexible plastic tubing or conduit - Slide over individual wires for protection.

• Metal wire mesh - Wrap entire strands of lights to block access.

• Old garden hose - Slice lengthwise and insert lights inside tubing.

• PVC piping - Encase sections prone to chewing.

• Aluminum foil - Chewing the reflective surface deters squirrels. Replace periodically.

Remove any existing teeth marks or exposed wires before applying protective wraps. Check that casings don't limit heat dissipation from lights.

Use Deterrent Scents and Substances

Strategically place unpleasant scented repellents near your Christmas lights:

• Moth balls or flakes - Strong odor keeps squirrels away.

• Ammonia-soaked cotton balls - Place out of reach in upside-down jars near wires.

• Cayenne pepper flakes - Sprinkling this spicy powder deters chewing.

Reapply scents after rain or snow. Avoid options toxic to kids or pets. Monitor for skin or respiratory irritation.

Employ Sounds, Flashes and Motion

Add devices that frighten squirrels with various stimuli:

• Noise makers - Blowers, ultrasonic repellents, or rattling pie pans activated by motion sensors.

• Sprinklers - Intermittent water spray from motion detector sprinkler heads.

• Shiny tinsel - Reflective silver strands blowing in wind distract and deter squirrels.

• Fake predators - Place owls, hawks, or snakes nearby to scare squirrels off.

Check noise restrictions in your neighborhood when using audible deterrents. Don't irritate or startle neighbors!

Use Commercial Animal Repellents

Look for products designed to drive away squirrels and other nuisance animals:

• Chemical urine or predator scents - Synthetic versions of coyote, fox, bobcat urine, etc.

• Granular repellents - Apply foul-tasting pellets around decorations.

• Liquid animal repellents - Spray perimeter areas around lights.

Read labels thoroughly and confirm safe use around decorations, pets, kids. Reapply as directed.

Install Physical Barriers and Guards

Block squirrel access to Christmas lights with physical barriers:

• Wire or mesh guards - Cover light strands with metal wire guards.

• Cinder blocks or chicken wire - Place temporary barriers around base of light displays.

• PVC pipe cages - Affix protective tubing around posts and rails to prevent climbing.

• Electrified wire - Low voltage electric wire creates a harmless shock.

Check that guards don't limit ventilation or create fire hazards for lights. Monitor children and pets around electrified wires.

When to Apply Squirrel Deterrents for Christmas Lights

Timing is an important factor when using anti-chewing strategies for outdoor Christmas lights.

Before Installing Lights

Treat wires with protective coatings like hot sauce or bitter sprays before hanging lights. Pretreating helps prevent squirrels from developing a taste for your lights.

Also install physical barriers like wire guards or blocked access points to poles before putting up lights. This prevents squirrels from accessing wires at all.

Immediately After Noticing Chewing

At the first sign of damage, address problem areas right away. Squirrels often return to the same spots repeatedly once chewing starts. Use repellents or wrap protective tubing around compromised wires immediately to prevent further damage.

Catch issues early before squirrels chew through critical wires that could cause entire light strands to fail.

Throughout Holiday Season

Check lights regularly and reapply taste, scent or texture deterrents frequently, especially after snow or rain.

Hungry squirrels are most persistent in chewing from late fall through winter when natural food is scarce. Maintain diligence throughout the entire holiday season.

Tips for Deterring Hungry, Determined Squirrels

Here are additional useful tips to enhance your squirrel-proofing efforts:

• Use multi-sensory deterrents like smelly repellent sprays plus physical tubing barriers.

• Combine several repellent strategies like light mesh, hot sauce and predator urine.

• Apply hot sauce, chewing gels or protective tubing to wires out of squirrels' reach.

• Ensure repellents and guards don't create fire or health hazards.

• Check for and seal potential access points like gaps in eaves and roof peaks.

• Prune overhanging branches giving squirrels access to light strands.

• Remove food sources like bird feeders to avoid drawing squirrels.

• Limit lighting durations to deter squirrels active at night.

• Consider hiring a professional pest control expert for severe squirrel infestations.

When to Call a Professional for Help with Squirrels

For minor squirrel nuisance issues, the deterrent methods described above should help safeguard your Christmas lights. However, if you encounter extensive repeated damage or notice signs of larger squirrel infestations, contacting a professional may be wise.

Indications your squirrel problem requires expert assistance:

• Repeated damage even after using multiple deterrents

• Large numbers of squirrels on the property

• Presence of baby squirrels or nests in trees/structures

• Chewing damage inside attics, soffits or interiors

• Structural damage to buildings from chewing or nesting

• Risks of electrocution from exposed wires

Licensed wildlife control professionals and pest management specialists have advanced techniques, equipment and expertise to remove squirrels humanely and protect your home from risks associated with infestations. They can:

• Inspect for entry points and seal off access.

• Install one-way exclusion devices and traps.

• Remove nests and baby squirrels.
