Rats really will chew through anything, and thatís what makes them so dangerous as wild animals that invade your home. Electrical wiring - theyíll chew right through it. The same applies to wood, plastics, and other building materials, including brick. In fact, there are few very materials that these rodents wonít be able to gnaw and claw their way through. In case you were wondering, aluminum flashing and steel wire mesh are two things you can use to keep them out. They canít chew through these two strong metals.



A ratís incisors will never stop growing, and thatís what makes their chewing action so impossible to stop. If the rats didnít gnaw and chew on things, their teeth would be very long. They need the chewing to wear them down. The fact they the rats might be chewing on your electrical wiring isnít something the rats have done on purpose to annoy you. It's just something they do - they chew through everything and anything that gets in their way.

If that electrical wiring is close to a wooden beam, or it touches that wooden beam, you have a very dangerous fire risk. That is actually one of the biggest concerns when you have rats in your attic, and is one of the biggest reasons why you should regularly check your attic for signs of damage, wear and tear, or animal invasion.

Of course, electrical wiring is just the tip of the iceberg. These are animals that really will chew through anything. If you have PVC pipes, they'll chew through that, and that can cause leaks, and in worst-case scenarios, even flooding. If you have wooden beams or rafters, they will chew that those too, and that can cause serious structural damage to your home. These kinds of repairs are not small repairs, and they will cost hundreds, and potentially even thousands of dollars to put right. Do you have that kind of cash floating away spare in case of rat repairs? In this current economic climate, many homeowners do not.

Wiring behind refrigerators meaning that white goods need to be replaced or repaired, damage to curtains, walls, furniture, urine stains, fur and grease staining, the feces lying around Ö Chewing is only one small part of a very big problem when you have a rat infestation.
