Every fall, as the temperature drops across Saskatchewan in October and November, mice go looking for somewhere warm to spend the winter. A parked car, a trailer in storage, an RV waiting for next season, or a combine sitting in the yard all make perfect mouse housing: the engine bay holds heat for hours, the interior is sheltered, and there is no shortage of soft material for nesting. The trouble starts when those mice begin chewing — wiring, insulation, hoses — and the first sign is often a dashboard warning light or a vehicle that will not start at all. The good news: in many cases the damage is covered. Here is how SGI rodent damage claims work, how to file one properly, and how to make sure the mice do not come back.
Why Rodents Target Vehicles in Fall and Winter
Mice are not being destructive for fun — they are following instinct. A mouse’s teeth grow constantly, so it has to chew to keep them worn down, and modern vehicle wiring, some of it wrapped in soy-based insulation, is an easy target. At the same time, a vehicle offers everything a mouse needs heading into a Saskatchewan winter: warmth, shelter from predators and wind, and shredded insulation, paper, and fabric for a nest.
Vehicles that sit unused are at the highest risk. Trailers, RVs, boats, classic cars, and farm machinery parked for weeks or months give mice the time to move in, raise young, and do serious damage undisturbed. SGI handles roughly 900 rodent-related vehicle claims a year, most of them in the colder months — and drivers in Regina and Saskatoon are far from exempt, even in the city.
Warning Signs of Rodent Damage
Rodent damage usually shows itself gradually, so it pays to know what to look for — especially before a vehicle goes into storage or comes back out of it:
- Chewed wires, hoses, or insulation under the hood
- Nests of shredded material in the air filter box or engine bay
- Droppings on the engine cover, in the glove box, or under the seats
- A musty or unusual smell coming through the vents
- Dashboard warning lights or strange electrical glitches
- Scratching or rustling sounds after the vehicle has sat unused
If you find any of these, take them seriously. Chewed wiring can cause shorts and even fires, and damage left unaddressed tends to grow into much bigger repair bills.
Does SGI Cover Rodent Damage?
In most cases, yes — if you carry comprehensive coverage. In Saskatchewan, rodent damage is treated as a comprehensive (non-collision) claim, in the same category as hail or vandalism. Your standard mandatory liability coverage on its own does not cover it, so it is worth checking your policy or asking your broker before you need it.
Two things to keep in mind. First, your comprehensive deductible applies, and SGI covers the rest of the approved repair cost. Second, timing matters: damage that builds up gradually through long-term neglect may be questioned, so report and document problems promptly rather than letting a stored vehicle sit for another season. If you are unsure whether your damage qualifies, your broker or SGI can confirm based on your policy.
How to File an SGI Rodent Damage Claim: Step by Step
Step 1: Stop driving if wiring is damaged
If you can see chewed or exposed wiring, do not keep driving the vehicle. Short circuits are a real fire risk — have it towed if necessary.
Step 2: Document everything with photos
Photograph the droppings, nests, chewed wires, and damaged insulation before anything is touched. Clear photos are the evidence your claim rests on, so do not clean up before documenting.
Step 3: Contact SGI or your broker
File the claim directly with SGI, through their online claim service, or through your insurance broker. The sooner the claim is opened, the smoother everything after it goes.
Step 4: Get an inspection and estimate
A mechanic’s inspection gives you a written summary of the cause of damage and a repair estimate for the claim file. The vehicle also needs to be properly cleaned and disinfected before or alongside the inspection — more on that below.
Step 5: Keep every receipt
Cleaning, repairs, towing, and any related costs should all be documented and kept with your claim paperwork.
Why Professional Cleanup Matters for Your Claim
Here is the part many people do not realize: a rodent-infested vehicle is a health hazard, not just a repair bill. Deer mouse droppings in Saskatchewan can carry hantavirus, a potentially fatal lung disease. Never sweep or vacuum droppings yourself — disturbing them dry can release the virus into the air you breathe. Professional cleanup means the droppings, nesting material, and contaminated debris are removed safely, and the interior, engine bay, and ventilation system are properly disinfected before you and your family use the vehicle again.
This is also where Green Pest Control can carry a lot of the load for you. Our SGI rodent claim support service for vehicles, trailers and RVs includes documenting the infestation for your claim file, complete mouse removal, droppings cleanup, hantavirus disinfection, and getting the vehicle inspection-ready — and we bill SGI directly, so you are not paying out of pocket and waiting for reimbursement. Because mice rarely travel alone, multiple treatments may be needed depending on infestation level, particularly where vehicles are stored near other harbourage. If you have found signs of mice in a vehicle in Regina, Saskatoon, or anywhere in Saskatchewan, call us at (306) 716-6900 and we will walk you through the next steps.
Prevention Tips for Vehicles, RVs and Trailers in Storage
Once the damage is fixed, a few habits keep it from happening again:
- Store vehicles indoors where possible, and seal gaps and entry points in the garage, shed, or storage building
- Remove attractants — bird seed, pet food, and garbage stored near vehicles are mouse magnets
- Check under the hood and in the air filter box regularly through the storage season
- Set traps around storage areas, compounds, and farmyards where vehicles are parked
- Move or run stored vehicles occasionally so they never sit completely undisturbed
- Consider a seasonal prevention plan if you store several vehicles, trailers, or machines
Mice move fast once the cold sets in, so fall is the time to act — check your stored vehicles now, and if you find damage, document it, open your claim, and get the cleanup done professionally and safely.
