rental car damage and liability insurance

Comprehensive car insurance provides coverage for damage to your vehicle that is not caused by a collision. It covers incidents like rodent damage, vandalism, weather events, and theft.

Comprehensive insurance is an optional add-on coverage. It is often required by lenders for leased or financed vehicles to protect their investment.

Adding comprehensive coverage to an auto policy typically costs an additional 7-11% in premiums. Cost varies based on:

  • Car make and model
  • Location
  • Driving history
Covered Losses Not Covered
Theft Mechanical failure
Vandalism Wear and tear
Rodent damage Improper maintenance

Rodent damage to vehicles

Rodents like mice, rats, squirrels, and chipmunks can cause extensive damage to vehicles when they crawl inside engine compartments, trunks, or cabins. They may chew through critical wires or build nests with fibrous materials.

Chewed wires are one of the most common forms of rodent damage. Rodents are attracted to the soy-based coatings of modern wiring. They also seem to enjoy chewing on rubber hoses, insulation, and other materials. This can result in:

  • Exposed and damaged wiring
  • Electrical shorts and fires
  • Stalled engines
  • Power losses
  • Check engine lights

Rodents may also shelter in hidden areas of cars and nest in air filters or ventilation systems. Their droppings, urine, and nesting debris can lead to:

  • Foul odors entering the cabin
  • Allergic reactions
  • Bacteria and viruses
  • Corroded components

Repairing rodent damage can be expensive. Some common costs include:

  • Wiring harness replacement - $200-$1000
  • Engine repair due to fire - $1500+
  • New air filters and cabin cleaning - $100-$300
  • Electrical shorts diagnosis - $100/hour

Filing an insurance claim is the best way to recover these costs. Comprehensive coverage will pay for repairs after the deductible is met.

Preventing rodent infestations can help avoid the need for repairs:

  • Park vehicles in garages when possible
  • Check under hood for signs of intrusion
  • Use commercial rodent deterrents
  • Remove food sources and garbage
  • Drive vehicle regularly

Reasons rodents damage vehicles:

  • Shelter - Hidden spaces are warm and protected
  • Nesting materials - Fibrous insulation and fabrics
  • Chewing instinct - Keeps teeth worn down
  • Attraction to wires - Soy-based casings smell/taste good

Rodent damage is often unpredictable and detection is difficult. But comprehensive insurance can provide vital protection against these common critter catastrophes for vehicle owners.

Filing an insurance claim for rodent damage

If you discover rodent damage to your vehicle, one of the first steps is to file an insurance claim with your provider. This section covers the key steps in the claims process.

Filing the Initial Claim

Contact your insurance company by phone or through their website/app. Provide:

  • Your policy number
  • Basic details about the damage
  • Where and when it occurred

The insurer will assign an adjuster to assess the claim. They will advise next steps.


Gather documentation related to the rodent damage and keep copies:

  • Photos showing chewed wires, nests, etc.
  • Repair estimates from mechanics
  • Receipts for related expenses
  • Records of preventive actions taken

Thorough documentation will help facilitate claim approval and payment.

Authorized Repair Shops

Insurers often have preferred repair shops in their network. Using these can streamline repairs and claims:

  • No need to get multiple repair estimates
  • Direct billing between shop and insurer
  • Guaranteed workmanship
  • Speeds up the claims process

However, you can choose any licensed auto repair shop.

Comprehensive Coverage Requirements

  • Damage caused by rodents is covered
  • Damage must exceed your policy deductible
  • Proper documentation must be submitted
  • No coverage lapses or exclusions apply

If requirements are met, your insurer will pay the portion beyond your deductible.

Claim Payment

Once the repairs are complete, the shop will submit invoices to the insurer. After confirming coverage, deductible, and receiving payment from you for your portion, the insurance company will pay the repair shop directly.

Preventing Future Damage

To help avoid repeat rodent damage:

  • Address gaps and holes where pests enter
  • Use deterrents: lights, noise, predator urine
  • Fix leaky pipes and clean up debris
  • Have a pest control expert inspect/treat

Document preventive measures like repairs and deterrent devices. This shows the insurance company you are trying to avoid further damage.

Overall, clearly understanding the claims process and comprehensive insurance requirements allows you to file smoothly and get your rodent damage covered. Taking preventive measures can also help reduce your risk going forward.

Coverage for rodent damage

A common question vehicle owners have is whether rodent damage is covered by their auto insurance policy. There are some key factors that determine if this type of claim will be approved.

Comprehensive Coverage

  • Damage from rodents like mice, rats, and squirrels is specifically covered under the comprehensive portion of auto insurance.
  • Comprehensive is optional - confirm you have this coverage before filing a claim.
  • It covers non-collision damage such as weather, vandalism, theft, and animal damage.

Policy Exclusions

  • Review your policy details for any exclusions related to rodents, vermin, or animals.
  • These may limit or exclude coverage for gnawed wires, nesting, droppings, etc.
  • Exclusions are not common but are more likely with certain insurers.

Filing Deadlines

  • Claims should be filed promptly after discovering rodent damage.
  • Most insurers require reporting within 1-3 days.
  • Late reporting could result in a coverage denial.


  • You pay the deductible amount before insurance covers further costs.
  • A higher deductible lowers your premiums but increases out-of-pocket costs.
  • The damage amount must exceed your deductible to get reimbursement.


  • Provide dated photos, repair estimates, and details on preventive actions.
  • Documentation showing diligent maintenance helps show damage was sudden/accidental.

Location and Storage

  • Damage that occurs when the vehicle is parked or stored for long periods is more readily approved than frequent/ongoing damage.
  • Consistent problems may be deemed result of negligence and excluded.

Pre-existing Damage

  • Damage present when you purchased the vehicle is not covered.
  • This is only an issue if you do not promptly identify rodent damage after buying the car.

Overall, comprehensive insurance is designed to cover unpredictable rodent damage. Carefully following policy guidelines, providing documentation, and demonstrating responsible car ownership helps ensure claims go smoothly.

Preventing rodent damage

The best way to deal with rodent damage to your vehicle is to prevent it in the first place. There are several effective deterrents and measures you can take.

Parking Locations

  • Park in an enclosed garage when possible.
  • Avoid long-term street parking or fields/wooded areas.
  • Concrete driveways or parking lots leave less shelter for rodents.

Vehicle Storage

For long-term storage:

  • Place dryer sheets in cabin and engine compartment.
  • Leave hood up to eliminate dark shelter.
  • Use mothballs or cotton balls with peppermint oil as deterrents.
  • Check under hood periodically for signs of rodent intrusion.

Sealing Entry Points

  • Use steel wool or copper mesh to close openings around wires in the engine bay.
  • Check firewall openings, wheel wells, and undercarriage for gaps.
  • Ensure hood seal and door seals are intact.
  • Plug any exposed ductwork leading into cabin areas.

Ongoing Repellents

  • Ultrasonic devices emit high frequency sound waves.
  • Sprinkling cayenne pepper can deter rodents from nesting in air filters.
  • Mothballs or ammonia-soaked rags can mimic predator scents.

With proactive steps, you can detect issues early and avoid extensive rodent damage. Confirm your comprehensive insurance coverage for peace of mind as an additional safeguard.

Reasons rodents damage vehicles

Rodents like mice, rats, squirrels and chipmunks frequently find their way into vehicle engine compartments and interiors. But what motivates them to chew through wires, insulation, hoses and other components?

Seeking Shelter

Rodents are drawn to the warm, dark, and protected environment inside vehicle cavities:

  • Engine compartments provide plenty of nooks and crannies.
  • They offer shelter from predators and the elements.
  • Insulation buffers sound and retains ambient engine heat.

Once inside, they begin nesting behaviors like gathering materials and establishing toilet areas.

Finding Food

Rodents have very strong senses of smell and taste. Potential food sources lure them in:

  • Soy-based wire insulation smells sweet.
  • Starch and cellulose are used in insulation, gaskets, filters.
  • Salt residue from leaked fluids.
  • Bits of food and trash transported inside.

They will nibble and sample these items seeking nutrition.

Basic Rodent Behaviors

Chewing, gnawing, and nesting are ingrained rodent behaviors:

  • Their teeth constantly grow so they need to chew to wear them down. Wires and hoses simulate tree branches.
  • Shredding materials to build nests satisfies natural instincts.
  • Urine and droppings mark territory and attract mates.

Damaging Effects

Common types of damage from these behaviors include:

  • Exposed and broken wire harnesses from chewing.
  • Clogged air intake from nest materials.
  • Corroded components from urine and feces.
  • Fires from electrical shorts.
  • Ruined insulation and fabrics.
Rodent Chewing Targets Nesting Sites
Mice Wires, hoses, insulation Air filters, vents, upholstery
Rats Wires, filters, rubber seals Under floor mats, inside doors
Squirrels Wires, upholstery, trim Vents, trunk, headliner

Preventing access by sealing openings, removing attractants, and using deterrents remains the best defense against costly rodent damage. Being aware of their behaviors helps better protect your vehicle.

Key factors in claim approval

When filing an insurance claim for rodent damage, there are some important considerations that can impact whether your claim is approved.

Comprehensive Coverage

  • Verify your policy includes comprehensive coverage for non-collision damage.
  • Review details to confirm damage by rodents is covered and not excluded.


  • Provide dated photos showing chewed wires, nests, droppings, etc. as evidence.
  • Have a mechanic verify the cause and extent of damage.
  • Note any attempts to deter rodents.

Damage Details

  • Damage must directly result from a covered peril like rodents.
  • Pre-existing damage before policy inception is not covered.
  • Minor cosmetic damage may fall below your deductible limit.

Storage Conditions

  • Frequent or ongoing damage in the same parking spot may be denied.
  • Damage that occurs when a car sits long-term is more readily approved.

Lapses in Coverage

  • Damage that occurs outside your policy coverage dates will be denied.
  • Maintain continuous, lapse-free comprehensive coverage.

Premium Payments

  • You must be up-to-date on insurance premium payments.
  • Claims can be denied if your account has a balance due.

Deductible Amount

  • Your deductible must be met before insurance covers further costs.
  • A higher deductible equals lower premiums but more out-of-pocket expense per claim.


  • Some policies exclude damage from rodents outright.
  • Most limit or exclude damage from lack of care or negligence.

Claims Limits

  • The total payout on your claim cannot exceed the value of your vehicle.
  • Check your policy limits for comprehensive claims specifically.

Satisfying these key criteria results in a smooth claim process. Your insurer wants to help you repair damage but must confirm coverage conditions are met. Maintaining your vehicle and preventing issues aids the process.

Benefits of comprehensive insurance
