How to Prevent Squirrels from Chewing Your Electrical Wires

squirrels electrical wires birmingham

Did you know that a squirrel can jump as far as 10 feet from the branch of a tree to the top of your home?

More than just an annoyance, squirrels can create a fire hazard when they chew through the wiring in your home. When squirrels choose to enter your attic to nest, the most effective way to prevent them from eating the electrical wiring is to evict them from your attic. This eliminates the fire hazards the squirrels’ chewing causes as well as eliminates the health hazards that arise from having squirrel feces and urine in your attic.

Here are a few tips for keeping squirrels from causing serious damage to your home’s wiring and your safety:

1. Thoroughly inspect your attic for tell-tale signs of squirrels. Signs include droppings, or areas where your attic’s insulation has been ripped apart and piled in what could be nests. Check for wires missing their insulated covering or show signs of chewing and listen for scratching noises in your attic, especially after dark, when nesting is most active.

2. Look closely around all of the edges of your attic, where the roof meets the top of the wall. You may find small holes the squirrels are using to enter your attic and take up residence. Most likely, the edges will appear chewed, as believe it or not, the squirrels are smart enough to take advantage of already existing holes and making them larger so they can get inside and nest.

3. Create an unwelcome and “anti-squirrel” environment in your attic. Play a radio or install a flashing light, both of which will annoy the squirrels and encourage them to take up residence elsewhere. If you’ve installed a one-way door, the squirrel will use the flap to exit and not be able to re-enter.

4. Once you’re absolutely certain they’re gone, patch the holes they’ve used to previously enter. The squirrels may have already nested, meaning there could be baby squirrels hidden in nests around your attic. Check very closely to be sure the mothers have taken the babies, otherwise they could die in your attic.

5. Trim the branches of your trees so that they end at least 10 to 12 feet from the top of your home. Most squirrels can’t jump further than that, so this should prevent squirrels from reaching your roof and subsequently the wires in your attic.

What is the future of solar power in Alabama?

Monday, January 6, 2020

The sun is the natural source of the most abundant, reliable, and pollution-free power in the world. However, problems with solar power, namely the expensive cost and inconsistent availability, have prevented it from becoming a more utilized energy source. Just like everything, eventually, it will be more affordable for the average homeowner. Could it be the new way people light up their homes in Alabama?

What others say about John's Electric Service

First, they were there within the hour of calling them. Secondly, I thought I had 2 bad florescent lights, but it turned out to be tripped GFI outlets. Instead of just going ahead and replacing the lights, the electrician found the tripped outlets and let me know that was all the problem was. He showed me where they were so, if I had a problem in the future I could look there first. I appreciate his honesty. It saved me a lot of money.

Solved a problem thus restoring my power to some areas of my house

Had a number of outlets not working and lost AC in 97 degree weather--he came twice the 1st time approx 1hr 20 minutes--wasn't able to locate problem---this I put on myself as I was unaware of putting a breaker box behind a vanity that hadn't been move since purchase of my house. Second visit after some search found problem 1hr

OK the skinny--I think he was professional--on time

Was upfront on costs

Problem once the second box was located was an easy fix so thought a touch high on price--that said it was upfront and had I had the answer to location as I should have I think the billing would be much lower so will put this on myself. In other words I don't think he would have ripped me off

Bonus was after having 4 others trying to blame AC and being told I needed a new one---he said everything in my problems was electrical--and viewing my AC said it was fine--no need of new unit--for the moment if right saving me $$$$
