When you think of pests invading your home, you might picture chewed furniture or dirty countertops. But did you know that rodents and other pests can cause serious electrical damage — creating fire hazards and costly repairs? This hidden risk is often overlooked, but knowing the signs and prevention tips can protect your home and family.
Why Rodents Target Electrical Systems
- Warmth and shelter: Wiring inside walls and attics provides cozy hiding spots.
- Nesting material: Chewing insulation and wires gives rodents soft materials for nests.
- Constant access: Small openings let mice and rats slip into wall cavities easily.
Common Electrical Damage Caused by Pests
- Chewed wires: Exposed wiring can cause shorts, flickering lights, and dead outlets.
- Damaged insulation: Leads to increased risk of electrical shock or fire.
- Nest buildup: Combustible materials near wiring increase fire hazards.
- Circuit breaker trips: Caused by shorts or faults in damaged wiring.
