How to Stop Rodents Chewing Wires in Your Home (Prevention Guide)

One of the most frequent calls we get for electrical services in Cincinnati and Northern Kentucky is for electrical damage from rodents chewing wires. Rats, mice and squirrels like to munch on electrical wiring routed through attics and inside wall voids.

In this blog, we’ll review what makes electrical wiring attractive to rodents, the risks of rodent activity, how to prevent it and what to do if you suspect rodents are making meals of your electrical wiring.

Why Do Rodents Like Chewing Wires?

Experiments to formulate wire insulation distasteful to rodents have been largely unsuccessful. Therefore, most experts believe it’s not because rodents like the taste of wiring, but an instinct to prevent teeth overgrowth.

Rodent teeth continuously grow and if they grow too long, it makes it hard to eat. In addition, rodents often see wiring as an obstacle. The rodent tries to make its way from one area of your home to another through holes in studs or joists.

Wiring is sometimes in the way. The mouse, rat, squirrel or other rodent assumes if he chews away the wiring he’ll be able to pass. Activity increases when the weather turns cold or we have several days of rain in Ohio and Kentucky. Rodents seek the warmth and shelter of your home.

Hazards of Rodents Chewing Wires in Cincinnati, OH and Northern Kentucky Homes

Whatever the reason, chewed wiring is no laughing matter. It can cause electrical outages and dangerous short circuits. It’s believed that rodent damage may be a major reason for house fires in which no other definite cause can be determined.

According to a report published this year from the National Fire Protection Association, (NFPA), electrical failures or malfunctions were the second leading source of U.S. house fires in 2012-2016.

To reduce the likelihood you’ll need electrical services in Cincinnati to repair rodent damage to wiring, here are some suggestions to prevent it:

How to Prevent Electrical Damage and Repairs from Rodents Chewing Wires

Seal Entry and Exit Points

Seal exterior holes and crevices that allow rodents into your attic or the interior of wall spaces. Typically, they enter to escape winter cold, then breed indoors.

Depending on the size of the hole, use spray foam insulation or masonry repair to fill it. For large holes in drywall, the material will need to be patched.

Mice regularly squeeze through openings ¼ of an inch or larger, so don’t underestimate their ability to move through cracks.

Reduce Access from Nearby Trees

Cut back tree limbs within 10 feet of your roof or the siding of your home. Squirrels can easily jump that far and rats are adept at leaping down from higher limbs that extend above the roof.

Assert Your Claim

Sure, it sounds funny, as if you need to poke your head in there and beat your chest. But seriously, inspect and clean attics and crawl spaces on regular intervals. Your occasional presence in these often neglected areas discourages rodents from nesting.

It also provides the opportunity to catch early signs of rodents before the population becomes very large. Which, frankly, happens quickly.

Mice are capable of up to 20 pinkies per litter and can repeat the reproductive cycle every three weeks! That’s a lot of rodents chewing wires in your Cincinnati or Northern Kentucky home.

Finally, be careful when it comes to poisons. Rodents which take poison back to the nest or die in hard-to-reach areas create an odor problem.

Request an Electrical System Evaluation

Get a wiring evaluation by a professional. A qualified electrician knows the routing of house wiring and how to access and inspect all spans to check for telltale signs of rodent damage.

Also make sure to inform an electrician of any electrical problems, like unexplained outages in parts of the house or tripped circuit breakers. Don’t forget, if you’re a member of the Apollo Care Plan, you’re entitled to a complementary electrical evaluation each year.

Our team of electricians and HVAC technicians are trained to look for clues rodents are present. Sometimes they find nesting material, carcasses or droppings in ventilation ductwork, which reduces your energy efficiency as well as introduces pollutants into your air.

"Ernie & Mike did a superb job on my new furnace and A/C installation. Despite having more than a day’s work to do, they came in and stayed until the job was done. They were organized, efficient, and protected the rest of the house well. Got both furnace and A/C installed the same day. Ernie was courteous, informative, and clearly knew his job better than anyone I’ve encountered before. The units look so good guests now get The Tour of our new system. Apollo is clearly not a fly-by-night company. I would recommend them to anyone in need of a new furnace and/or A/C."

"I called Apollo because of a water leak I thought I had in our upstairs shower going into the kitchen. Robbie came and assured me everything was fine & looked at all the other plumbing. He ended up changing a few pipes for our washer & clearing a drain. He was very nice & knowledgeable with all my questions. I ended up signing up for the care plan & was very happy with my service."
- Cassandra B.
"The team at Apollo exceeded my expectations. As a business owner, my attention to the details and commitment to providing excellent service is high. From the sales rep. to the installation team, everyone’s performance was outstanding. For example, the installation team went to great lengths to protect our floors, placing floor runners and across the wood floors and up the stairs. They even were spot washing walls upon their departure. I highly recommend this company."

"We scheduled an estimate AND a tune-up. We knew something was wrong with our furnace, but hoped we could make it through the rest of the season. Upon telling Bill what our furnace was doing, he warned us immediately what the possible outcome was going to be; a cracked heat exchanger. He watched the flames roll backward, tested carbon monoxide levels, which were so high they meter’s last reading was 5,600 before saying “high”. He immediately shut it down, tagged it, and explained that with levels that high and children in our home he wanted off right away. He continued his inspection and showed us via a camera that not only was it cracked in multiple places, but had holes all over it. He gave us a few options for repairing it; his knowledge as well as genuine concern was beneficial and refreshing. Luckily we also scheduled an estimator, Micah, to come too and we were able to get costs between repairing and replacing (with several options). We decided to replace with a much higher efficiency furnace and one sized properly to our home. Hands down, not only did they both provide us great service and knowledge, but without sounding dramatic, they may have saved our lives. This was our first time calling Apollo, but it won’t be our last."

"Apollo is an excellent company. I always receive great service. Alex A. was professional and friendly. He kept me informed during the process of checking my furnace and heat pump to make sure they were working properly. The company makes sure you are notified who is coming and when they are on the way. All my interactions with the company have been wonderful."
