Squirrels can be a nuisance in the garden by chewing through wiring and damaging plants. Here is an in-depth guide on effective strategies to deter squirrels and protect your garden.
Why Squirrels Chew Wires
Squirrels are rodents with continuously growing incisor teeth. They chew on objects to file down and maintain their teeth. Wires also contain scent marks from your hands or oils that attract squirrels.
The main reasons squirrels chew wires are:
-
To file down their continuously growing teeth - Squirrels need to chew to wear down their incisor teeth. Wires are convenient chew toys.
-
Exposed wires appear vulnerable - Visible, unprotected wiring seems like an easy target for squirrels.
-
Wires contain attractive scents - Your scent, oils, or residues on the wires smell interesting to curious squirrels.
-
Squirrels may be bored - With no other outlets, squirrels will chew wires for amusement.
-
Electrical current or salt taste - Squirrels may be drawn to the electrical current or salt from your sweat on the wires.
Dangers of Squirrels Chewing Wires
It's crucial to protect your wiring, as squirrel damage can cause:
-
Electrical shorts or fires - Exposed, chewed wiring is a fire hazard if wires touch.
-
Power outages - Chewed wires cause electrical failures, leaving you without power.
-
Electrocution risk - Squirrels could get electrocuted while chewing live wires.
-
Costly repairs - Replacing damaged wiring, cables, or electrical devices gets expensive.
-
Ruined plants - Chewed irrigation system wires prevent watering, killing plants.
Effective Ways to Stop Squirrels Chewing Wires
There are several effective tactics to stop squirrels chewing wires listed below:
Remove Access Points
Block access by sealing entry holes or gaps where squirrels enter your yard and reach the wires.
-
Caulk, cover, or screen off openings in rooflines, eaves, fascia, attics, and crawl spaces.
-
Use wire mesh to fill hole or gaps in fences. Bury fencing 6 inches underground to prevent digging underneath.
Protect Exposed Wiring
Insulate vulnerable wiring to prevent chewing:
-
Use flexible plastic conduit or vinyl tubing to cover wires.
-
Wrap exposed wiring in aluminum foil or wire mesh.
Use Repellents
Apply taste, scent, or touch repellents to discourage chewing:
-
Coat wires with hot pepper wax, capsaicin gel, or ammonia-soaked cotton balls. Reapply after rain.
-
Sprinkle predator urine granules or coyote droppings around wires.
-
Attach cotton balls with menthol vapour rub on wires. The scent repels squirrels.
Install Physical Barriers
Block access to vulnerable wiring:
-
Place wiring through PVC pipe or flexible tubing to prevent chewing.
-
Staple metal mesh like chicken wire over exposed wires.
-
Wrap electric tape tightly around entire wire length.
Use Frightening Devices
Deter squirrels from the area with frightening sounds, lights, or movement:
-
Place predator decoys like fake owls, snakes, or hawks near wiring. Move periodically.
-
Set up motion-activated sprinklers, lights, or alarms when squirrels approach.
-
Use an ultrasonic squirrel repeller that emits high frequency sounds.
Apply Commercial Wire Protectants
Use flexible cable protectant tubing marketed for shielding wires from rodents:
-
Slip pliable plastic tubing over wires to block chewing.
-
Apply a bitter cable coating squirrels dislike chewing. Reapply annually.
-
Insert wiring through rigid metal spiral wrap or conduit tubing.
Remove Attractants
Eliminate tempting food sources near wiring that draw squirrels:
-
Clean up any seeds, nuts, or fruit dropped near wires.
-
Prune overhanging branches squirrels use to access wires.
-
Ensure trash bins are sealed so squirrels can't scavenge.
Provide Distractions
Give squirrels alternative outlets like chew toys to divert them:
- Offer roped corn cobs, sticks, bones, or wood blocks to chew.
-Scatter bird seed away from wiring to provide alternative foraging sites.
- Set up a squirrel feeder with corn, nuts or seeds on the other side of your yard.
Use Humane Removal
As a last resort, have squirrels humanely trapped and relocated if they persistently chew wires.
Seek advice from a wildlife control professional to ensure proper trapping and release methods.
Protecting Wiring from Squirrels Long-Term
For a long-term solution, follow these tips:
-
Monitor garden wiring and seal new access holes immediately before squirrels find them.
-
Check for signs of chewing weekly and implement deterrents at the first sign of damage.
-
Ensure all wiring is fully insulated or concealed from squirrels.
-
Periodically refresh repellent scents or coatings during peak squirrel chewing seasons.
-
Trim vegetation at least 3 feet back from wiring to eliminate squirrel access and hiding spots.
-
Maintain distractions like chew toys, bird feeders, or corn cobs to divert squirrels.
-
Contact a wildlife removal specialist promptly if issues continue despite prevention efforts.
By taking proactive measures to shield vulnerable wiring and discouraging squirrel interest, you can protect the safety of your garden wiring and avoid inconvenient damage from squirrel chewing long-term.
