Are Mice A Fire Hazard?

Mice can and do spark fires in homes

In previous blogs and articles on our website, we’ve talked about mice a lot. We’ve covered topics such as how mice get inside New Jersey homes, how to tell the difference between mice and rats, why mice are just as much a summer pest problem as they are any other time of the year – really the list goes on. What we’ve not mentioned (or if we have, very briefly) is how mice can actually be a potential fire hazard.

How do mice cause house fires?

To be fair, it’s not just mice that are considered fire hazards, rats and other house-infesting rodents can be lumped into this group as well.  But why or rather how are they considered fire hazards in homes and other structures in New Jersey? It can all be summed up in two words -their teeth. You see, rodents have incisors that do not stop growing. The only way for these critters to keep their teeth at a manageable length is to chew. Sure, they chew on all manner of things including items made from wood, plastic, rubber, anything they can chomp into really but they also gnaw on and through the plastic coating on electrical wires. 

Electricity that runs through wires is hot. The plastic coating surrounding the wires protects whatever is near the wire from becoming overheated. Unfortunately, when rodents chew through the coating, they expose hot wires. What’s more, they actually chew on and fray the wires themselves. A couple of things can happen as a result, one the heat escaping might cause wood or other material nearby to ignite or two, the frayed wire might cause a short circuit that sparks.

How to prevent fires caused by rodents

Since it is estimated that up to 25% of fires of unknown origins are rodent-related, it only seems logical to protect your home from becoming part of that statistic by implementing measures that take away their opportunity to infest. With that in mind, our New Jersey pest control pros have put together a few rodent prevention tips that are designed to keep rodents out of your house and also make your property less attractive to them. 

  • Seal up every possible opening on the exterior of your house- from the ground level right up to the roofline. 
  • Make sure your garage doors are closed when not in use and make sure you cannot see daylight when they are closed.
  • Trim tree limbs so that they do not touch the roof or any other part of your home. Likewise, do not let shrubs or other landscaping elements come into contact with the sides of your house.
  • Store firewood several feet away from the dwelling.
  • Remove anything from your lawn and property that rodents might use as shelter such as tires, old cars, tall grasses, dense vegetation. 
  • Keep trash cans sealed tight, do not overflow or leave trash bags beside cans.
  • Do not leave pet food outside.
