The Eye-Opening Stats
The numbers surrounding rodent-caused fires are both surprising and alarming. Across the United States, experts estimate that 20-25% of all fires with unknown causes are linked to rodents. According to the National Fire Protection Association (NFPA), 322,000 house fires were reported in 2023. While it’s difficult to pinpoint precisely how many were caused by rodents, it’s reasonable to assume that thousands—or even tens of thousands—of fires may have started this way. That’s not a risk any Northern California homeowner wants to take, especially during the dry months when fire hazards are already higher.
How Do Rodents Start House Fires?
Rodents, such as mice and rats, are naturally destructive. Their incisors grow continuously, so they must constantly chew on things to keep their teeth in check. Everything becomes fair game when they get inside a home, from clothing and toiletries to more critical parts of the house.
Some of the most dangerous targets for rodents are:
- Electrical wires: Gnawed wires can short-circuit, creating sparks that may ignite fires.
- Gas lines: Even minor damage can result in leaks, increasing the risk of a sudden, unexpected fire.
- Insulation or combustible materials: Rodents can drag debris and nesting material close to heat sources, fueling the fire risk.
These fires often start in out-of-the-way places, such as attics, crawl spaces, or behind walls; in other words, areas where a small spark can smolder unnoticed until it becomes a major problem. Once a fire ignites, the damage can be substantial and extremely dangerous for anyone in the home.
How to Keep Fire-Starting Rodents Out of Your House
Preventing rodent-related fires begins with keeping rodents out. That might sound obvious, but it’s trickier than you might think. Mice only need a hole the size of a dime to squeeze inside, and rats can gnaw through soft materials to create new openings. For Northern California homeowners, this is especially relevant: older homes, decks, attics, and homes near greenbelts or parks are particularly vulnerable.
With over 20 years of experience in rodent control, Big Time Pest Control has developed proven methods to keep these destructive pests out. Here are their top prevention tips:
Outdoor Prevention:
- Seal all cracks, gaps, and holes around the foundation, siding, windows, and doors.
- Install door sweeps, window screens, and weatherstripping to block entry points.
- Trim back foliage and tree branches that touch the house, roof, or eaves.
- Keep your yard clean and free of clutter or debris where rodents can hide.
- Store firewood, compost, and trash bins at least 20 feet from your home.
- Remove pet food, bird seed, and other outdoor food sources that attract rodents.
- Fix drainage problems and eliminate standing water, which can draw rodents.
Indoor Prevention:
- Store all food in sealed containers.
- Wash dishes and wipe down counters and floors after meals.
- Reduce clutter, particularly in storage areas, closets, attics, and basements.
- Address indoor moisture issues, such as leaks or condensation, which can attract rodents.
What to Do If Rodents Get in Your House
If you notice signs of rodents, such as droppings, gnaw marks, greasy rub marks along walls, or sounds of scurrying, it’s time to call in the professionals. Many homeowners try to handle rodents on their own, but there’s too much at stake to take that chance.
Here’s why professional rodent control matters:
- Rodents travel in groups. Seeing one mouse usually means there are more hiding nearby. A single trap is rarely enough.
- Nests are often hidden. Rodents build nests in hard-to-reach places like attics, crawl spaces, or behind walls. Without the right tools, these areas are nearly impossible to access.
- Speed is critical. If left unchecked, mice and rats can cause fire hazards, structural damage, and health risks. Professional removal is faster and more thorough.
