As the weather cools, rodents such as mice and squirrels begin seeking warm, sheltered spaces to nest—and your home often provides the perfect spot. Unfortunately, their presence isn’t just inconvenient; it can also be dangerous. At Secured Environments Pest and Wildlife Services, we want homeowners to understand how rodents can cause serious damage to electrical wiring and insulation during the fall and winter months.
Rodents have teeth that continuously grow, which means they need to gnaw constantly to keep them from becoming too long. Electrical wiring, insulation, and even structural materials often become their targets. In doing so, they can create hidden damage that leads to costly repairs.
When rodents chew through wiring, they strip away protective coating, leaving live wires exposed. This not only disrupts your electrical system—causing flickering lights, shorts, or outages—but also increases the risk of electrical fires. Many house fires each year are linked to rodent-related wiring damage.
Rodents often burrow into wall, attic, or basement insulation to create nests. As they shred and soil the material, insulation loses its effectiveness, making your home less energy efficient. Over time, this damage can drive up heating bills during the colder months.
The best way to protect your home is to prevent rodents from getting inside in the first place. Sealing entry points, trimming back vegetation near your house, and keeping food properly stored are all important steps. Once rodents are inside, professional removal and exclusion services are the safest, most effective solutions.
Don’t wait until you notice the signs of rodent damage. As fall settles in, schedule an inspection with Secured Environments Pest and Wildlife Services. We’ll help safeguard your home against rodents so you can enjoy a warm, worry-free season.
