Electrical damage caused by Rats

Rodents, particularly rats, are known to cause significant damage to homes and properties. Electrical damage caused by rats is easily overlooked. In Northland, New Zealand, rats are a common pest that can infiltrate homes and cause serious damage to electrical systems.

Electrical damage caused by rats can occur in a number of ways. Rats are notorious for their ability to gnaw on anything they can sink their teeth into, including electrical wires. This can cause significant damage to electrical wiring, which can lead to power outages and serious electrical fires inside your home.
In addition to chewing on wires, rats can also cause damage to electrical equipment such as transformers, circuit breakers, and other electrical gear. This can result in costly repairs, replacing components, as well as potential safety hazards.
Rats are attracted to electrical systems for a number of reasons. The warmth can provide a cosy spot for rats to nest, and the insulation on electrical wires can be an attractive material for rats to use for building their nests.

Signs rats may have damaged your wiring

  • Lights flickering, or one circuit cutting out on its own
  • Breakers or RCDs tripping for no obvious reason
  • A burning or hot-plastic smell, especially near switches, sockets or the ceiling
  • Scratching or scurrying in the ceiling or walls, usually at night
  • Droppings, nests or chewed cable in the roof space

What to do

Don’t touch chewed or exposed cables. If you can smell burning, switch the power off at the switchboard and call an electrician straight away. Otherwise, book an inspection: we can check the affected wiring, repair or replace damaged cable, and make the installation safe. See our electrical maintenance service for more.

In order to prevent electrical damage caused by rats, it is important to take steps to keep rats out of your home in the first place. This can include sealing any cracks or gaps in your home’s exterior, installing mesh screens on vents and other openings, and keeping food and rubbish stored securely to prevent attracting rats.
If you suspect that rats have already caused damage to your home’s electrical system, it is crucial to have a professional electrician assess the situation as soon as possible. They can identify any damage and make necessary repairs to ensure that your home is safe and functioning properly.
In addition to preventing damage, there are also plenty of steps you can take to deter rats from your property. This can include using rat traps and poison, as well as using sonic deterrents or ultrasonic repellents. You can do this yourself or engage a pest control company to carry out a regular rodent control program.
