How to Squirrel-Proof Your Boat
As boat owners prepare for the season, many are surprised to find unwanted guests—squirrels and other rodents—that have turned their vessel into a winter retreat. These critters can cause serious damage by chewing through wiring, upholstery, and even fuel lines.
Western Financial Group, a 100% Canadian company, can help you navigate your car, home, boat, and business insurance during this period of economic uncertainty.
To keep your boat in top condition, follow these squirrel-proofing steps.
Step 1: Inspect your boat for signs of squirrel activity
Before launching for the season, conduct a thorough inspection:
Look for entry points – Check around hatches, vents, and any small gaps where squirrels may have squeezed through.
Check for droppings and nesting materials – Squirrels build nests using leaves, insulation, or fabric, often in hidden areas like storage compartments or engine bays.
Inspect wiring and upholstery – Rodents love to chew on electrical wiring and seat cushions, which can create fire hazards and costly repairs.
Step 2: Block entry points and seal gaps
Once you identify potential entry points, take action to prevent squirrels from getting in:
Use steel mesh or hardware cloth – Cover vents and openings with strong materials that rodents can't chew through.
Seal small gaps – Use marine-grade sealant or expandable foam to close off any cracks or crevices.
Keep hatches and compartments securely closed – Always latch doors and covers when the boat is not in use.
Step 3: Discourage squirrels with repellents
Keeping squirrels away requires making your boat an unappealing place to nest:
Use natural deterrents – Peppermint oil, soap, vinegar, or predator scent repellents can discourage rodents from settling in.
Install ultrasonic devices – These emit high-frequency sounds that irritate pests but are harmless to humans.
Try motion-activated lights or sprinklers – If your boat is stored outdoors, these can scare off squirrels before they get too close.
Step 4: Store your boat properly in the off-season
A well-maintained storage routine can prevent infestations:
Keep your boat clean and free of food – Even small crumbs can attract rodents.
Use a high-quality boat cover – Ensure it fits snugly to prevent easy access.
Elevate your boat off the ground – If stored on land, use stands or blocks to make it harder for squirrels to climb aboard.
Check regularly – Periodic inspections throughout the off-season can catch problems before they escalate.
Does boat insurance cover rodent damage?
Check for coverage on animal damage – Some policies include coverage for rodent-related destruction, while others may exclude it.
Confirm coverage for electrical and mechanical damage – If squirrels chew through wiring, will your policy cover repairs?
Consider comprehensive boat coverage – This can protect against a wide range of risks, including vandalism, storms, and wildlife damage.
