For being so small, mice and rats can cause quite a bit of damage! A rodent's front teeth continuously grow, meaning they have to gnaw to keep them short. They may chew on your furniture, clothes, papers, or other belongings. They are also known to chew on wires, which creates a significant fire hazard in your home. On top of this, they are extremely unsanitary and can spread diseases and viruses to you and your family.
