How Much Damage Can Rats & Mice Do To Your Home?

Rats and mice are not just a nuisance; they can also cause significant damage to your home. Understanding the extent of this damage is crucial for effective pest control and maintenance of your property.

As the colder weather begins to set in, we quickly see a substantial increase in frantic, rat related phone calls. This is because as the temperature drops, rats and mice are forced to find warm, cozy nooks and crannies to wait out the cold weather and unfortunately they typically end up in homes and businesses during the winter.

How much damage can rats and mice do to your property?

Aside from carrying disease and being extremely unsanitary, rats and mice are also very destructive. Both have continuously growing teeth that require constant gnawing to be kept short, which can lead to significant damage to your home and belongings.

Rats and mice have even been implicated in causing house fires after chewing through wiring! They can also cause structural damage to hill sides and retaining walls, contaminate food and their droppings have been found to be potential asthma triggers. It is also important to keep in mind that most insurance companies do not cover damage caused by pests.

Remember, having a professional pest control technician come out and check your property is going to be far less expensive than having to repair structural damage or replace damaged furniture, wiring and clothes. Prevention is always better than a cure, especially when you could possibly be facing up to hundreds of rodents. So next time you see a mouse or rat scamper along the skirting boards, along the back fence, or you hear noises in your roof – think about your wallet and the expense of repair bills if the infestation is not taken care of in the early stages.
