Mice and rats are notorious for chewing on electrical wires in homes and commercial buildings, but why do they do it?

Why Do Mice and Rats Chew on Wires

There are several reasons rodents can be drawn to chew on electrical wires and other fixtures in your home.

First, it’s important to understand that chewing is a natural behavior for rodents. Their incisor teeth grow continuously and need to chew on objects to keep them from getting too long. You often see rodents chewing on wood, plastic, and other materials.

In addition to chewing to keep their teeth at a manageable length, rodents also chew to help wear down their teeth. Their incisors are very sharp and can become painful if they get too long. Chewing on hard surfaces helps to keep their teeth at a comfortable level.

Finally, some experts believe chewing on electrical wires may help rodents relieve stress. This is because the electrical current produces a vibration that can be soothing to rodents.

Whatever the reason, chewing on electrical wires is a dangerous behavior that can lead to fires and other serious damage. If you suspect that rodents are chewing on electrical wires in your home, it’s important to contact a professional pest control company right away.

What Are the Electrical Issues When Rodents Are Chewing Wires

Mice chewing on electrical wires is a major cause of electric failures and fires. According to the National Fire Protection Association, electric malfunctions were the second leading cause of house fires in the United States from 2012 to 2016.

When rodents chew on wires, it can create a number of electrical issues. This is because chewing can damage the insulation on the wires, which can lead to shorts or even fires. Additionally, chewing can also create gaps in the wires, which can allow electricity to arc, which can also cause fires.

One of the best ways to prevent electrical issues is to keep your wires well-protected. This means putting them in conduit or enclosed spaces where rodents cannot get to them.

Additionally, you can use rodent-resistant materials for your wires, such as steel wool or mesh. If you do find that your wires have been damaged, it’s important to have them repaired or replaced as soon as possible to prevent any further damage from happening.
